MENGER, M.D. — SAN ANTONIO, TEXAS GUESSAZ & FERLET COMPANY 1913 Biographical Sketch of the Author Dr. Rudolph Menger, of San Antonio, is a native of Texas, and was born in that city in 1851. He is the son of Simon M. and Augusta Louisa Menger, both parents being natives of Thuringia, Germany, who came to Texas in 1846, landing at old Indianola. Mr. Menger had been well ed- ucated in Germany, was a thorough musician, and had there taught ‘school and music. From Indianola he pushed inland to Comal County, and located on a farm near New Braunfels; at the same time he began teaching vocal music. He moved to Bexar County, and located on a farm a few miles from San Antonio, and from his home he rode into San Antonio and gave singing lessons: Then he located with his family at ‘Boerne, Texas. About 1850 or a little earlier, he moved to the city, and probably continued teaching music incidentally for several years. About 1858 he started a soap factory, the first ever conducted in all the south- west. Several of his sons were associated with him in, business, as they grew to manhood, and his son, Erick, conducted the business later on. August went to Houston and started in business there for himself, and established a flourishing business which he conducted until his death, in | 1893. Two sons, Oscar and August, served in the Confederate army; Au- gust served until the close, but Oscar was twice severely wounded, and disabled from his wounds, and was compelled to return home. The father died in 1892 at the ripe old age of eighty-five years; he was a prominent Mason. The mother had died some years prior. Our sub- ject’s primary education was secured in San Antonio, at the old Ger- man-English school on South Alamo street, and he began life as a clerk in Kalteyer’s drug store, and then under the able instructions of the proprietor, he also began the study of pharmacy. He was thus en- gared from 1866 to 1869, when he went to Germany, and entered the University at Leipsic, in Saxony, where he began the study of medicine. He spent five years in study there, and graduated in November, 1874. He returned at once to San Antonio, and became assistant surgeon in the United States army until. the close of 1875, when he was appointed city physician, and served until 1881; then for several years he devoted his time to his private practice which became quite extended. In 1892, he was again appointed to the office of city physician, where he served in that office to the satisfaction of-all. In fact, he greatly improved the appointment of the city hospital, and that instifution under his direction was almost perfect in its operation and utility.4 He also has a large gen- eral practice; had been an active member of the West Texas Medical Society, and contributed freely to various médical journals. He was tor a long time medical examiner for the New York Life Insurance Com- pany, and many other old line companies. He was married in 1879, to Miss Barbara C. Menger, a native of San Antonio, and daughter of Wil- liam’ L. Menger of the same family name, but no kin. Her father was an old and well known pioneer to San Antonio, from Germany. He erect- ed the Menger Hotel, one of the finest hotels in all the United States, and a popular resort to all visitors to the Alamo City. He was a very prom- inent and active citizen of San Antonio, and started the first brewery in the city, conjointly with Charlev Degen, lately deceased. _ To the union of our subject and wife eight. children have been born: Minnie, (now Mrs. Wm. R. Hoffman), born July 4th, 1880, Edward, August, Louis, Gustave, Rudolph, Theodore and Margaret Menger. The sons all have prominent and responsible positions, and the elders are the proprietors of the elegant “Menger Apartment House” on East Commerce Street, THE AUTHOR Preface This little work of “Private and Personal Observations and Remin- iscenses” is dedicated to all friends of Nature, and to San Antonians in. particular. It is not pretended to be a atncdly 4 scientific work, though based on scientific principles, but more a popular and _ res- ponsible treatise on Nature observations around San Antonio, the most up- to-date and metropolitan city of Texas; with over 100,000 inhabitants, with unexcelled climate, sanitary surroundings, artesian water supply, sew- erage ‘system, unmatched public utilities, superb city parks and amuse- ment resorts, up-to-date public buildings, a world-famed military post, and last but not least, unequaled historic reminiscenses. It is a treatise on insect and animal lifé, and some outing and hunting reminis- censes in particular; and it is nearly alla reprint of original articles pub- lished lately in Texas Field and National Guardsman, of which Colonel O. C. Guessaz and Louis A. Guessaz are the editors, and to whom the wri- ter is indebted for many courtesies. Also is the writer indebted to the San Antonio: Daily Express for the loan of engravings from original pho- tos by the writer, and to Mr. Albert Friedrich of San Antonio for the loan of the elegant halftone plates of his unexcelled collection of Texas deer horns, etc. A work of this kind takes many years of personal and accurate obser- vations and reliable original data, as well as up-to-date and original illus- trations of each subject, and, in how far this has been accomplished, is left to the kind judgment of the reader. For want of space, time and chronological data, it’ would be fu- tile to attempt writing a detailed description of “Old San Antonio,” of which only a few works exist, and among these the newest and best is written by Charles Merritt Barnes, entitled “(Combats and Conquests of Immortal Heroes,” published by the Guessaz & Ferlet Company of San Antonio, Texas (1910). It is a work of superior merit and profusely illus- trated with early day scenes. ‘Tue AUTHOR. OBSERVATIONS ON TEXAS INSECT AND ANIMAL LIFE IN GENERAL With Reference to the Objects Seen on the Miniature Views Herein in Particular ‘Formerly the quaint .and his- toric old Spanish-Méxican town of San Antonio, now the Metropolis and pride of Southwest’ Texas, due to its semi-tropical climate and ‘luxuriant vegetation and soil, in its frontier days harbored a large number of dangerous insects, which nowadays are nearly extinct; but the scorpion and centipede, and a few others of its kind, are yet occasionally met with along the river bottoms, under old bark of trees, under large, flat stones, and among accumulated debris after a flood. Though dangerous, they are not as fatal in their venom- inoculation, as for instance, some variety of scorpions and centepedes of tropical Mexico; however, their repugnant appearance is enough for us to let them, as many other poisonous insects, severely alone. Being a great friend of outdoor : life, whenever opportunity allowed it I had lots of practical experience in my younger years to study all kinds of Texas insects and animals during hunting and outing tours; and after, or during such trips also prepared a nice photo collec- tion of various of the Texas fauna of Southwest Texas. A small part of this collection is represented in the miniature photo submitted herewith, on page 6, the original ob- jects being prepared on 4x6 plates, while the entire original framed col- lection is 26 by 33 inches in size. It would be going too far, enume- rating in detail all the objects of this miniature photo collection; some of them, however, undoubt- edly will interest the readers, for instance, the first upper object representing the headparts with poison fangs of a very young Texas | centepede which was, when alive, — hardly two inches in length, and ‘which shows how boldly, even at this remote age of its existence, the poison fangs are already de- veloped, as also the feelers and man- dibles, and is readily seen on the original and highly magnified photo- micrograph of this same insect. In the third lower row, a centepede is depicted, which was about six inches in length, and captured in a stable by afriend, (Edw. Heus- inger, Esq., Secretary of the San Antonio Scientific Society.) During an outing in the hills of Helotes, north of San Antonio, the writer once came across one of the attractive and globular Cereus Cacti in full bloom. It was one large conglomerated bun- | dle of about ten or twelve cactus, ~ one ingrown close to the other, so as to form a perfect rounded mound, the size of a large bucket; and, for reason of its attractive blossoms of golden-yellow color we were induced to dig the entire con- glomeration out for transplanta- tion at home. First we tried this with a piece of mesquite wood, and, after coming down to the roots of the cactus, I put my right hand under the loosened plant in order to give it the final lift. ‘As quick as lightning, however, I withdrew my hand, for I received a fearful and excruciating sting in my index finger, from a large female scorpion, which had prepared its breeding nest in a furrow leading toward the 6 TEXAS NATURE OBSERVATIONS AND REMINISCENCES. base of that cactus, close to the roots of same. The sting was so painful that, in spite of some chloroform. used, it lasted the entire day. Usually on such trips I carried my emer- gency box with me, containing a few necessary surgical appliances Pe " photo, also seen in the miniature collection, (second last row) after having chloroformed all the scor- pions. The following statistics of the tropical scorpion show same to be a more dangerous type than the Texas variety: 1: MINIATURE ‘PHOTO COLLECTION OF TEXAS INSECTS AND OTHER ANIMALS and also a hypodermic syringe, carbolic acid, cocaine, iodine, per- manganate of potassium, camphor, etc., and some of these appliances would have given instant relief. Before disposing of the large scorpion and its young brood, which were quite fully developed already, I managed to prepare a From an authentic official source from a border town of Mexico, the following deaths occurred from the stings of scorpions (mostly children of the poor, and a few peons rambling around barefooted at night): In 1906 fifty-four deaths. occurred; in 1907 fifty-one deaths; and in 1908, forty-seven deaths. TEXAS NATURE OBSERVATIONS AND REMINISCENCES, 7 Formerly, the report said, many more deaths occurred, as scorpions were then much more numerous, and a bounty has been paid for nearly 100 years for the extermi- nation of scorpions in Mexico. (Official figures from Probate Office in Mexico, at Durango.) These statistics, as compared to our North American scorpions show that our scorpions are a rather harmless creature as far as death- Mexican scorpion as compared to our Texas variety. It is of nearly one half size longer and of a light yellowish-brown color, and its tail end venom receptacle harbors a most poisonous fluid which it in- jects through its needle-sharp and curved tail-end-claw. This speci- men was sent to the writer by Dr. Jackson of Durango, Mexico, and it killed a mouse in confine- ment with same, the experiment A Texas SCORPION WITH YOUNG ONES cases from same are concerned, and as to Southwest Texas, no deaths from the scorpion bite are resorded in the official mortuary records of San Antonio, as far as twenty or more years back. (Jno. U. Mueller, Secretary of San An- tonio Bureau of Deaths, having looked up this record for me.) The separate photo-view of three scorpions in natural size, shows the great difference in size of the being conducted by my friend, Dr. A. Lange, veterinary Surgeon of San Antonio. Such experi- ments, I may add, whilst they appear horrid to some, it should be remembered that mice and rats, being great public nuisances, they are often cruelly dealt with by drowning or strangled to death in traps, or poisoned, and a chicken or a turkey’s head is without much feeling, chopped off 8 TEXAS NATURE OBSERVATIONS AND REMINISCENCES, with a hatchet, a daily .occur- rance, and hogs killed with a butcher knife—all offer a slow death and the incarnate fiend in human flesh, the murderer, stabs or shoots a fellow being to death without much warning.

TEXAS NATURE OBSERVATIONS AND REMINISCENCES. 9 A sub-species of scorpion, the so-called vinaigron or “nigger- killer,” is nowadays a rare item in the inland sections of Texas, how- ever, they are said to abound quite numerously around the frontier towns. I always had been inter- ested to see one of these long- sheered, black scorpions alive and study their habits, but never had ducted with the said Del Rio specimen. It was my intention to get a mouse, and put it alive in the bottle with this specimen, for scientific observation, but not being able to get one at the time, I had several cockroaches caught and put them all in the bottle, to give the giant scorpion company and to note what would happen.

R., presented me with a large live’ specimen which was caught around Del Rio, Texas, and brought here in a wide-mouthed bottle. So much has been said and contradicted, ‘that they are as poisonous as a rattlesnake,” and that they sting with their long -eurved tail, that I was anxious to find this out, if possible. The latter, however, could not be prov- edjby a little experiment I con- Hardly was this done when the roaches became exceedingly lively and crawled like mad around the bottom part of the bottle, while the vinaigron also became more lively and fully outstretching its sheerlike arms suddenly grabbed one of the roaches and drew same in a curved line toward its mouth- parts, and sucked its lifejuice out. Then it began mutilating its body with its powerful. and moveable endsheers, and to feed on the fleshy parts. In a short while, two more of the roaches were thus 10 TEXAS NATURE OBSERVATIONS AND REMINISCENCES. kiued by the vinaigron. But in no instance had we observed that it used its long tail to sting and inoculate its victims; it simp- ly grabbed the roaches quickly with its sheers and held them thus to the mouthpiece for further ‘disposal.

It is interesting to note the ana- 12 TEXAS NATURE OBSERVATIONS AND REMINISCENCES, tomical difference between the head _of aneel and that of a rattlesnake, (lower row), and the close resem- blance of an eel to a nonpoison- ous snake. The depicted beast (Crotalus horridus) came near making the writer ‘“immune’”’ from writing about it for good. A party of us were hunting quail and wild doves in a friend’s pasture where lots of sunflowers ripen in falltime, and millions of doves signal, only about four or five feet in front of me. Luckily, however, I had not crossed the wire, or else the reptile would have struck me, since it had al- ready coiled into a spiral shape and was rattling fiercely. As quick as I noticed the beast, I put a shell into the gun and shot its neck in two. The snake had unusually large fangs, and I took a close focus view of the head afterwards— A Texas CENTEPEDE . congregated on mesquite trees by a nearby tank, for their nocturnal rest. We were close to the wire fence of the pasture, when several doves were seen alighting close to us but inside the wire enclosure. With the gun unloaded, and in the act of crossing between the wires, I was horrified to hear a huge rattlesnake giving its warning nicely depicted on page 13. Had my leg been entangled in¥ the wire fence, I certainly would have been struck; but as it was the rat- tler got the worst of it. As to Texas prairie snakes in general, occasionally one comes across queer freaks of nature, such as have been also described in the Texas. Field some years TEXAS NATURE OBSERVATIONS AND REMINISCENCES, 13 ago. During an outing with a number of friends last. fall along the San Antonio River, below San Antonio, one of. our party, whilst getting ready to put his fishing line into the water, was surprised by a rustling among the leaves and shrubbery along the river bottom, and upon closer search, one of the multi-colored kingsnakes was seen battling with another variety of prairie snake. It had the other shake in its mouth, and had nearly entirely swallowed it. At ‘another outing, near the same - fishing place about a mile below the Mission Espada, we came across a very large kingsnake, which had. in its mouth and throat a young kingsnake, and we were in doubt whether this latter instance was a case of protection of its offspring, or, as with the other specimen, a case of cannibalism. Both of these snakes were photographed, and one of the views is the second one on the lower row seen in the miniature photo collection. Dur- ‘ing that same day of our out- ing, whilst getting a bucket of water from a spring close to a ravine near the. river, I met a moccasin about one and a half feet long in my path, and the snake at once showed fight by thrusting its head upward with wide-open mouth. This genuine moccasin. of the ‘‘cotton-mouth”’ variety, when first seen was of. unusual thickness, and therefore I.was the more anxious to. kill it, to note what it had swallowed. With a stick and heavy blow, I nearly severed its head from its body, and bringing it on a forked stick to camp, we all guessed what it might have in its stomach, some guessed it was a frog, others said it was a toad, and: a lady naturalist of our party suggested a rat. On opening its abdomen, we immediately saw that our lady naturalist had guessed correctly, for it contained a full-size water- rat. The photo in the second last row, shows the same small moc- casin with the rat exposed in its stomach. Near the neck-part of the snake, which was split open from the severe blow, the photo shows the tail of the rat protruding outside. As to the various types of the Texas tarantula spider, much su- perstition and ignorance still exists. | Asarule, they are quite as harmless as many other poisonous animals, if not annoyed oy incidentally touched. A detailed account of our Texas prairie spiders has been pub- lished some years ago by the writer in Texas Field, which will be found on the following pages. The small jet black and reddish-striped jumping tarantula, encountered occasionally in gardens and forests, is about the most dangerous type.to be encoun- tered, and the writer could cite sev- eral serious but not fatal, cases of venom-inoculation from these in- sects. One large type of tarantula, rarely -met with in these days in inhabited places, but occasionally encountered in open prairies, where they sometimes move in large colonies, is seen: depicted in the third row of the collection. This same huge tarantula was captured by Private A. F. Denton, U. S. Army, in camp near Fort .McIn- tosh, Texas, and Mr. Denton sent the animal alive to San Antonio, where pictures of same were taken by Wm. Stucke, Dr. A. Lange, Veterinary Surgeon, and myself, and Isubmit one of the photos on page 15 showing the monster tar- antula in front of the rat it killed. (The photo being taken in the sunlight through the glass panel of the box at close range). In 14 TEXAS NATURE OBSERVATIONS AND REMINISCENCES, order to note its venomous char- acter, and the way in which it inoculates its victims, Dr. Lange put a large gutter-rat in a secure glass box with the tarantula, which inoculated the rat several times, and it died in about five and the venom serves at the same time to preserve the victims, insects, birds, mice, etc., as food supply to them or their offspring. Such is also known to be the case in the tarantula-killing wasp (first view, second row) which, however, | } 1 t | Texas FEMALE TARANTULA--(Natural Size). - hours. This shows that the ve- nom of this spider is a slow acting poison, gradually paralyzing the motor centers, with pralysis of — the extremities and respiratory centers, according to the amount of venom inoculated. Usually these, and other poisonous animals inoculate their victim only once, is not the regular tarantula-killer, which is of more slender structure, but powerfully built and which inoculates its victims with its sharp daggers, situated at the abdomen, and which communicates with the poison bladder of. the wasp’s abdomen. (Abdominal parts of this wasp species depicted TEXAS NATURE OBSERVATIONS AND REMINISCENCES, 15 in third row, last two photos). _I prepared the accompanying separate photograph of two poison fangs of the same species of taran- tula as the one described above, the specimens being also sent by Mr. Denton from Fort McIntosh. The venom of these animals seems to be stored away, so to say, in the mandibles, between the flesh (muscular tissue) in ducts of two separate cavities which communi- cate with the poison fang. The photos show the right and left mandibles opened artificially, the both mandibles and the fangs are instantly put in motion in an erect posture, and the fangs are suddenly plunged or hooked in the flesh of the victim, when an infinitesimal quantity of the dead- ly poison is injected into the tissues and absorbed by the capil- lary circulation. On examining the original tarantula mandibles sent by Mr. Denton, with a mag- nifying glass, both of the fangs showed at the upper curvature and close to the apex, a very minute outlet, and the lower photo Texas TARANTULA (Wits Rat It KitzEp.) upper one in part and the lower one in its entirety up to the apex of the curved poison-claw or fang, showing both specimens magni- fied about three times their nor- mal size. The mandibles and fang consist externally of a hard, dark brown shell, and both mandibles are covered with black, hairy bristles. When at rest, the curved fangs are retracted toward the base of the mandible: but when in the act of inoculating its victims (as noticed by Dr. Lange and myself in the case of the rat) herein shows»the thin wire piece which had been placed through the artificially opened mandible cavity along the opened fang, with its exit near the point of the fang, resembling in this respect the anatomical arrangement of the rattlesnake fang. Finally, the miniature photos show an interesting group of mos- quito-larvae (first row, second view), with stinging apparatus, and nearly fully developed, to escape their watery element, and also depicted in the separate photo- 16- TEXAS NATURE OBSERVATIONS AND REMINISCENCES. micrograph herein, showing, in up- per row, some of the larvae mos- ‘quitoes nearly fully developed, with the long, curved sting, etc., and below some remotely developed mosquito larvae are seen. They were originally gathered from a stagnant pool of rain water ina bucket in the rear of a drug store, which contained millions of them in all stages of development. On the third row of the photos, two views of the pestiferous house- “MANDIBLES WITH FANG OF THE TEXAS TARANTULA fly with eggs and ‘larval flies are seen; and on first view, last row, the sharp daggers of the blood thirsty horsefly; also the eye- globe of a fly; a number of tobacco beetles and larvae of such, infest- ing tobacco.

Two INTERESTING FLEAS OF a Mouse _ Fleas on various types of quad- rupeds vary somewhat as to size, shape and color; and the photo herein represents a male and female flea of a mouse. Note the long outstretched hindlegs, and the stinging apparatus, which is nicely represented in the following separ- ate photomicrograph. Tue Knives ann Daccers oF FLEAS TEXAS NATURE OBSERVATIONS AND REMINISCENCES. 17 This photomicrograph shows a flea’s stinging apparatus, magni- fied considerably, with sharp out- lines of the slightly curved daggers —which the insect inserts into the tissues and capillary layers of its victims’ skin to draw blood; ‘the stinging and_blood-sucking act being accomplished through rythmical muscular action of its head and stinging apparatus and suction tube. Some of the tropical and local sand-fleas have very powerfully developed stinging im- plements and cause intense irrita- tion with inflammation and ulcera- tion of the parts injured. The second photograph shows a small part of one of the hairy front feet of the flea, adjoining the long daggers. New Texas Antkiller A peculiar and rare insect in our climate had been sent to me ‘some time ago by the Daily Ex- press for identification, which had been previously sent to the Express office by V. 8. Kowalk of Pana Maria, Texas, in a small ‘square box, including remnants of earth and sand from an anthole and large numbers of butchered- up ants. When sent to me the ant-destroyer was still alive, and I subjected same and all the ants and earth remnants to a close ex- amination and photoreproduction. It is seen on the photograph here- in, about natural size, and readily illustrates how this ant-killer had disposed of its victims—our large ‘and poisonous red earth-ant, and ‘shows the powerful, large claws, ‘or fangs, its front head possesses —unlike any other insect of its ‘size that I am aware of. As stated, when received, this ant-killer still showed signs of life —as it moved about in a warm room and the first impression it made was the resemblance to some tarantula spider for a young vin- ‘aigron, an animal which has some characteristics of the scorpion and of some spider species alike. On -aeccount of its divided body be- tween head and thorax (meso-tho- rax), the position of the eyes and being supplied with haired and clawed legs, both of these animals belong under the class of arachni- dans or the spider family. As the letter sent along by V. 8. Kowalk, of Pana Maria is of much interest and importance in connection with the ant-killing qualities of this insect, it is herewith reproduced in full as follows: ‘‘T am sending you under separ- ate cover one bug. that will eat red ants and I want you to find out what kind of a bug it is. I found it in the ants’ nest just kill- ing them and eating them about a week ago, and I kept him in that box ever since. I turn him loose once a day in the ants’ nest to have his meal.’’ In viewing the photo herein, it is seen how this animal had cleared up with the anthole and dissected the ants, fragments of which—heads, bodies and single feet— being scattered all over the photo-view. This it accomplished by a regular ‘‘saw mechanism’’ the insect is supplied with at its head mouth parts similar to an ant itself. In examining the in- sect it was seen that two large projecting and mandible-like or- gans supply its front head, and that each of these organs had two extra scissors-like movable fangs, which it uses in grabbing and cut- ting up the ants. The head is small as compared -to these protuding powerful fangs and the head is supplied at its frontal margin with two glittering 18 TEXAS NATURE OBSERVATIONS AND REMINISCENCES, black eyes, also seen on photo. Its ten feet and its entire body is sup- plied with yellowish-red hair, and the joints of the two front feet are of black color, and they serve as feelers rather than legs in loco- motion. The technical name of this arach- nidan is Galeodes araneoides. ‘‘A recent traveler in Palestine relates that when living in tents on the plains of the Jordan, near Jericho, each night as nearly as possible between 9:30 and 10 o’clock, several sulpogids entered the tent room, running and racing with great speed over everything —tables, ‘chairs and beds—just amil New Texas Ant KILLER It is certainly a rare inhabitant of Texas, but perhaps from fav- orable (sandy) soil conditions and our sub-tropical climate, it was implanted, or it may be indigen- ous to that particular district of Bexar County where it was found and observed killing ants. It be- longs to the order of Solpugidea, a small but remarkable group of tropical or semi-tropical arach- nids. This is ‘what one authority relates of its life habits: like mad creatures, but apparent- ly with no definite object, per- haps only attracted by the lights burning in the tent. When dis- turbed in their diurnal hiding places they showed fight and were extremely pugnacious, but their being venomous is doubtful, though the Arabs seemed to dread them quite as much as they dread- ed the scorpions, which were also numerous under the large stones lying about.’’ TEXAS NATURE OBSERVATIONS AND REMINISCENCES, 19 The Tobacco and Drug Store Beetle In beginning to enumerate some of my private reminiscenses in na- ture observations, including ob- servations on Texas insect life, in the ‘‘Texas Field and National Guardsman,’’ the peculiar life history of one of the minutest and boldest of injurious insects, the tobacco and the so-called drug- store beetle, may find first place in these sketches; and the follow- ing is substantially a reprint from the Guide to Nature; a monthly magazine devoted principally to nature study, and edited by Prof. Edward F. Bigelow, Sound Beach, Conn. In his editorial columns, Prof. ‘Bigelow introduced the above matter in the following compli- mentary and highly appreciated words: < ‘*No. letters and contributions come to the Guide to Nature, which show more faithful and ef- ficient interest in nature than -‘ those from Dr. R.

The photograph shows the larvae Fig. 2. (1) Plug Tobacco Infested with the Tobacco Larvae. (2) Tobacco and Drug Store Beetles with Larvae. (3) Drug Store Beetles at Normal Size. in their natural positions as they had not been touched. Near these larval tobacco beet- les are seen some holes and fur- rows in the cigar which the ma- ture beetles and afterwards these developing larvae had prepared. It seems that during the fall-and winter the mature insects perfor- ate the tobacco and also other material such as food stuffs and drugs, producing a round deep hole not larger than the body of the insect, and. then deposit. the ova inside the tunneled holes when after a certain length of time the larvae seen on the plug cut tobac- eo (FigJI.) and the cigar specimen develop. This process has been witnessed off and on years ago and again lately by the writer when the furrows of these beetles had been exposed in to- bacco and some drugs, either of which they feed upon but with preference for the tobacco and usually for the best brand of to- bacco goods. These minute insects are occa- sionally and numerously found in dried vegetable drugs and house- ‘hold goods. But lately my friend, the druggist, happened to find an | old package of orris root powder ‘in which numerous round and oval. shaped bodies of granular appear-~ ance were present which after mounting and microscopical ex- amination I found to be composed mainly of the cocoons of the min- ute tobacco beetle and I prepared Two Tobacco Raa cee Drug Store Beetle (Lower) and Larvae. a photograph of.them magnified slightly (Fig. IV.).. Nearly all of these beetle cocoons: were in. the TEXAS NATURE OBSERVATIONS AND REMINISCENCES. 21 breeding cycle, i. e., most of them after opening the minute globular capsule showed a small live and curved larva. In others the ma- turing larva beetles could be seen, the larval state being in appear- ance identically the same as photo- graphed in Figs. 2 and 3. On closer inspection of Fig. 4 several of the whitish larvae of this beetle are seen, for instance at the places marked 1, and also two of the ma- ture tobacco beetles, (center right rear). Some of these larvae were quite disfigured in general ap- pearance from the fine orris root powder adhering to their fine ~ Fig. 4. , Cocoons of the Tobacco Beetle with Larvae Partly or Entirely Encapsulated. hairy filaments. In a few artifi- cially opened cocoons the larva is seen quite plainly in the illustra- tion. It is an interesting fact, also stated by Mr. Lucas, that these tobacco beetles prefer the best brand of tobacco and the more so as they are occasionally found in tobacco which had been sealed air- tight in tin or wooden boxes and therefore the probability presents itself that these pests had been conveyed through tobacco goods in the tobacco factories before be- ing put on the market, it being very difficult to detect the minute ova. How these beetles develop in all sorts of tobacco is seen, as a second example, in the so-called plug tobacco, Fig. 2 (1), which I also procured from the druggist. I prepared the view with an ob- jective lens applied to the camera, showing the tobacco larvae about. one-half times magnified, also the second figure of the same photo- graph, showing some of the larvae of the drug store beetle and the tobacco insect and also the ap- pearance and size (about one-half larger of the tobacco and the drug beetle (the latter being more slender). In further experimenting with this matter, I succeeded in pre- paring the view, (Fig.3,) using an extra strong lens to the camera at quite near focus, show- ing six of the tobacco larvae, two full-grown tobacco beetles and one drug store beetle (the lowest one in the photograph) magnified considerably. The third illustration in Fig. 2 shows the closely allied drug store beetle, named because of its pref- erance of invading drug’ store goods and infesting precisely in the same manner as the tobacco beetle. This view shows. the beetles in very slightly less than normal size. This drug store beetle is more slenderly built than the tobacco beetle, but otherwise is of a similar, reddish brown color and very active in its move- ments. Both the tobacco and drug store beetle, it seems, undergo about one and the same cycle of development and’ when the ova are deposited in favorable media of a powdered nature, such as rhu- barb, orris root, slippery elm, lin- seed meal, tobacco or cayenne vepiper, the ovum transforming into the larval state is encysted 22 TEXAS NATURE OBSERVATIONS AND REMINISCENCES. into the globular forms similar to these seen in Fig. 4 and similar to the genesis of other forms of in- sect life. ; The harm these minute insects are liable to do to tobacco, food stuffs and drugs is often enor- mous, and they are often a great plague to dealers in tobacco and drugs and, because of their minute size and rapid movements, are dif- ficult to exterminate. Being winged as other beetles, they can fly and migrate to distant places ‘and there perform the same havoe and multiply enormously. Both these minute beetles above described tally with the observa- tions of Dr. L. O. Howard, (Farm- ers’ Bulletin 120) and Dr. F. H. Chittenden (Bulletin No. 4, Divis. Entom. U. 8. Department of Ag- riculture and in our case the matter is the more. interesting, having found and depicted -the larvae in situ and the larva of the drug store beetle encapsulated in the peculiar globular cocoons de- scribed and illustrated herein. Dr. Chittenden says in regard:to the tobacco beetle, ‘‘as a tobacco feed- er it outranks that species (the drug store beetle) and also ap- pears to favor certain medicinal plants not so often affected by the sitodrepa (drug store beetle.) ‘‘Of household supplies it has been found infesting cayenne pep- per, ginger, rhubarb, rice, figs, yeast cakes and prepared fish food. It has been reported as destructive to silk and plush up- holstery and the past year did considerable damage to dried and preserved herbarium specimens in Washington, Of drugs it is par- tial to ergot and turmeric and to- baceo it devours in every form.’’ The druggists and tobacco deal- ers throughout the country un- doubtedly are familiar with the above minute pests and this mat- ter, I believe, will be appreciated by reading these memoranda on same. On another occasion I happened to shell out another larval beetle from a cigar in its maturing cycle of development—and a most in- teresting study it was! Its eubie length was only about one-eighth of an inch, and it was in its shed- ding stadium. After detecting this specimen, which was partly (its thoracic and head parts, an- tennae, legs and part of the ab- domen) denuded of its previous external integument or hull and of white color. I mounted it in Photo-Micrograph of Maturing Tobacco ; _ Beetle Larvae Highly Magnified.Original one-eighth inch. glycerine on a slide glass, and at once prepared the pho-micro- graph seen herein, which I believe an unusually interesting and rare specimen to study the genesis of such minute beetles. The microscope and the photo- graphic reproduction from the original specimen show how the -developing offspring of this min- ute larva (hardly one-eighth of an inch long) sheds its previous integumental environments and gradually, by means of rythmical TEXAS NATURE OBSERVATIONS AND REMINISCENCES. 23 contraction and expansion of its flexible body—similar to the shed- ding process of a snake—frees itself entirely of all its’ former hulls. The latter are nicely seen on this photograph—about half way stripped of its new anatomy —the lower dark outlines with the characteristic hairy integumental covering (a) and (b) being grad- ually peeled off and folded up at the base part (ab) of the new beetle’s abdomen, when the thus “newborn”’ little fellow is about ‘‘ripe’’ to escape into the world— after further evolution of its tho- racic organs, the wing parts and other of its anatomy. Some out- line of the (ringed) abdomen of this maturing tobacco beetle are quite plainly seen through the dark outlines of the old hull (b) and the developing feet (c) and two antennal appendages—the jointed and curved organs (d) at the head parts (e) with both dark eyes with lens, and the thoracic outlines (f) are quite consnicuous. The entire process resembles some- what the shedding process of cer- tain hairy caterpillars (larval butterflies) and other forms of insect life, including the vast numbers of all genera of beetles. When I first detected this speci- men it showed life, but its move- ments were very feeble and hard- ly perceptible, mainly from ex- posure, perhaps. It was found snugly imbedded between some of the cigar foldings, in a furrow similar to the larvae found and described and illustrated by the. writer in the June issue of The Guide to Nature, but it is a much further advanced pupal state than the one seen in the previous speci- men of the single cigar specimen. The Texas ‘‘Devilshorse’’ or Mantis Insect and Its Breeding Nest It is a noteworthy axiom in in- sect life that all insects, even those minute species hardly visi- ble to the naked eye, develop from ova or eggs, each ovum undergo- ing a regular cycle of develop- ment, typical to its sex; and the sects, but it was only of late that. I became aware of the manner in which this mantis insect breeds and develons its offspring. It was in- the summer of 1911 that a friend, a farmer from the Olmos settlement, north of San ee Younc ManTIS AND Ova--(Magnified one-third) genesis of the devilshorse or man- ‘tis insect makes no exception. It is but little generally known how this peculiar insect does develop. The writer is quite familiar with the breeding history of most in- Antonio, brought a small, square paper box to my office contain- ing the peculiar breeding nest of a devilshorse and its contents— hundreds of small and_ slender shaped young ones, in various sta- 24 TEXAS NATURE OBSERVATIONS AND REMINISCENCES. ges of development, and some of the ova. A number of these tiny, long legged insects and the ova in va- rious developmental stages, were mounted on a glass slide and pho- toreproduced. The engraving of same herein shows the small in- | sects plainly, enlarged about one- third ‘time original size. During outings, later on, several of such peculiar breeding nests of the devilshorse were encountered along the river banks and hilly regions south of San Antonio, on Fig. 1. Nest cut in two, showing cell apartments. Fig. 2. Nest intact. various trees and shrubbery, with preference on the mesquite tree and a small leafed acacia brush, loaded with scarlet red and glob- ular blossoms. A small branch of this latter brush containing one such mantis nest was removed, and the photo of same herein shows the peculiar ‘‘caterpillar- like’’ shape of this nest, showing the inside appearance and some of the many ‘cell apartments in which the old insect had deposited its eggs. These nests are about one to’two inches in length and worm-like shape; and its oval shaped body is ribbed and of ex- ceedingly compact structure—the old insect using some kind of a gum, perhaps mesquite gum, or perhaps it manufactures a gum of its own, to build its nest, and glues it on the branches or the trunk of a tree. The tubular cell apartments of which this breed- ing nest is composed and which, when finished, is as hard as rock, -reminds one of the cell arrange- ments of the wasp nest and some other insects; and the ova develop. on about the same principle as the wasps and bees, etc. The full grown devilshorse, of which an original picture from nature is appended herein, is nearly too well known generally to go into details herein about it. There exist various types of these mantis insects, and some of them attain enormous proportions and they all are of a repugnent and fearful looking nature— how- ever, they are entirely harmless. They are remarkable for their slender grotesque form. One spe- cies has a pair of legs in front re- sembling a person’s hands when folded in prayer and _ is often called the praying mantis. In writing one evening years ago, attracted by the bright elec- trie light, one of these long leg- ged insects suddenly appeared near my writing paper, and a queer aspect it was to see the insect standing erect on its hind legs, and twisting its large bulg- ing and glossy eye globes from one side to the other—watching the movements of my hand in writing. Some timid persons nat- urally get very excited, in encoun- tering a devilshorse insect, but: these insects nossess no weapons of inoculation, and they only scare a. person by reason of their pe- TEXAS NATURE OBSERVATIONS AND REMINISCENCES. 25. culiar. and characteristic position of the two front legs as seen also on the photo. These insects have many ene- mies, especially birds and tree liz- ards. Some time ago during an outing and camping under a huge body and off it went into a hol- low of the tree to finish its meal. These tree lizards, by the way, are very useful animals, as they live entirely on insects, and they should not be molested in any way. There are various types of FuLt Grown Mantis IN ‘PRAYING’?

With a sud- den jump, several feet off, one of the lizards, grabbed the insect’s tree lizards in our forests and prairie plains and an interesting lot they are when seen circling around a tree trunk ‘‘playing hid- ing,’’ like the wild squirrel in its ~ haunts when trying to evade the hunter’s gun. The Cotton Boll-Weevil Pest In the following memoranda, some of the original private data are enumerated herein anent the tiny pestiferous cotton boll-weevil inséct that has caused millions of losses to the Texas cotton crops in late years; and, for better un- derstanding the matter is illus- trated with several original photo- micrographs which, at this time were prepared by the writer many years ago, and were considered the first illustrations of boll-wee- vils ever made before by the pho- tomicrographie ‘process, (being used also in Leslie’s Weekly). The insects proper at the time shown in one of the illustrations herein were obtained from Mr. P. G. Lueas, druggist, and at pres- ent alderman of San Antonio, who procured them from a German farmer and had a large number of live specimens concealed in a wide-mouthed bottle, supplied. with. buds and bolls of the cotton plant. The insects were not lar- ger than a common fly; six legged, winged, very lively and excéed- ingly greedy. From what could be observed in Mr. Lucas’ collec- tion and- on sdéme of our cotton fields near town, the insects lay numerous eggs inside the punc- tured bolls or buds or rather they crawl inside the cracks of the boll capsule and perhaps breed there. The eggs develop numerous mag- gots and these are soon trans- formed into the young boll-wee- 26 TEXAS NATURE OBSERVATIONS AND REMINISCENCES. vils which at once crawl or fly around, if disturbed. One of the photo cuts shows several of the mature insects; they are so lively and tenacious to kill that they had to be chloroformed before a photo reproduction could be made of them. The following cut shows Microscopic appearance of the Boll Weevil's Nostrils, or Boring Apparatus, considerably magnifi d, showing part of head, eyes, nostrils, antennez, and the curved fangs on end parts. the microscopic appearance of the nostril or boring apparatus of the boll-weevil. It shows the front part of its head with both eyes (partly destroyed from pressure in mounting), the long and slight- ly curved proboscis with two deli- cate feelers (antennae), and its extreme end part is supplied with two curved fangs. The latter un- doubtedly serve to lacerate the tissues of the cotton plant, espe- cially the cotton bolls and buds whence they bore further and through the entire capsule or buds. A sub-species of this insect is occasionally very numerously en- countered in other plants, espe- cially in cereals; and perhaps those injuring corn, acorns, beans and peas, etc., belong to the same class. They bore, with a similar proboscis as the one of the boll- weevil, through the outer hull of the corn, ete., and perhaps hiber- nate there until favorable condi- tions produces new crops of these pestiferous insects. Some months ago I noticed in the so-called Mexican beans a great number of these insects; they had not been noticed until cooking the beans, when the shriveled, dark objects were noticed inside the shell in the corner of the beans and they resembled very much the cotton boll-weevil. The body of the boll-weevil is of dark grey color, broad at the rear and narrow toward the head which is supplied, as stated, with the long, curved proboscis and antennae or feelers. Some writer in the Galveston News related his experience on boll-weevils cap- tured alive and placed in a tightly corked bottle. He brought this bottle to an ice factory and there froze it in the middle of a 200- pound cake of ice. After this the cake of ice was put on exhibition on the street. ‘‘After melting, Seven Cotton Boll Weevils Magnified Slightly the weevils were exposed to the sunshine and after thirty hours captive in this frozen state it was proven that the weevils showed signs of active life.’’ No wonder the search for an agent, chemicals or otherwise, is baffling the minds of researchers. Fortunately though some ways and means undoubted- . ly will be found to capture and destroy them. TEXAS NATURE OBSERVATIONS AND REMINISCENCES, 27 The Fly Nuisance. There exist in all communities and outside of these, two main types of pestiferous flies—the com- mon housefly. and the socalled blowfiy—or dumpingfly, as they dump myriads of eggs on decaying and offensive material, as. well as on meat of all kinds. Both of these fly species are a great public nuisance, for various reasons. Both of them can be kept outside of dwellings by properly screening the houses, stables, etc. The call is to exterminate them—kill as many as possible, as thereby mil- lions of offspring will not exist in the near future, which would perhaps molest you or contaminate your food-articles or transmit dis- ease germs directly. , Just now again sanitarians and our health department are giving considerable thought to the eradi- cation of the fly nuisance, and they urge to screen the houses and premises and keep them clean and in a sanitary condition. Sta- bles especially, and outhouses, slaughter houses, hog pens, and in fact all such’ places where decaying and offensive material is liableto accumulate, should constantly receive sanitary atten- tion, as flies and other injurious. insects breed therein. By keeping such places as clean as possible and occasionally through sprink- ling with lime and coal oil, carbolic acid, etc., much good can be done. With our common houseflies, always more ‘or less flies with sting-weapons commingle, and many such, especially of the stable variety, resemble the common house fly very closely. The cluster-fly also often commingles with the housefly; it is somewhat larger, with smooth colored dark abdomen and studded with yellowish hair. It is, however, not as active as our common fly and is often subjected to a peculiar reddish fungoid growth or parasite, which often kills the fly and is thus seen adhering to the window panes, walls, etc. A large variety of other obnoxious fly species are the blowflies, those large and shining flies, with glitter- ing blue or green body. The majority of them belong to the ‘viviparous insects, the eggs being matured inside the fly’s abdomen, .and deposited in form of minute, wriggling yellowish-white worms. Some such species, however, lay a large number of very minute, oval-shaped and elongated eggs, depositing same on all sorts of fresh or decaying meats and food- stuffs, and with much preference also on venison of all kinds, and they therefore are the most. disgusting flies. on record. In slaughter-houses (not screened) hog pens and on dead animals they swarm by the millions and they breed and multiply in an exceedingly short time and inimmense numbers. On the prai- ries and plains dead animals are usually covered with them, black masses of such flies and billions _ of their larvae, and while feeding on such decaying animal matter they are liable to be swept by the wind currents into inhabited places and here infect occupants of dwell- ings or the domestic animals. By their immense numbers and multiplication they also do some good in absorbing putrid fluids and tissues, but. our common turkey buzzard—that great sanita- ty scavenger of the prairies and plains—does_ vastly better serv- ice in disposing of a dead animal. These so-called ‘‘dumping flies” or blowflies are also and especially a great nuisance at certain seasons of the year in camp, during outings, fighing time, hunting, etc., and parties attempting a pro- longed outing trip in the woods should provide themselves with mosquito netting or wire screens to cover the foodstuffs and game 28 TEXAS NATURE OBSERVATIONS AND REMINISCENCES. in particular, as the blowflies will sure be there in a short time and game and fish of ali kinds if not properly protected are in- fected. In order to show the reader the inside anatomy of a blowfly variety, The small worms seen on the photo were alive and crawling but were made motionless, for photo reproduction, with a few drops of chloroform. The view was taken with an extra-near focusing lens, showing Larce Type or FemaLe Houserry Depositinc Maturep Ecos. (Magnified from Nature.) a photograph of two such flies are appended herein, (page 29) magni- fied several times. The abdomen of one of these flies had been opened artificially. It was not the com- mon blue bottle blowfly variety, but, a sub-species of a larger variety of,;our common housefly. both flies magnified several times.

As a rule, however, most species of flies deposit prema- ture ova and sooner or later, according to temperature and other environments, these are developed into the larva and pupa states. Two Common HovusEFLigEs --« Slightly Magnified: Lower One with Opened Abdo- men, Showing the Man tee ease or Flyworms (Lar- va ies). Both of these flies, I may state, when captured on a window pane, were quite large and the abdomen distended, and one deposited living worms shortly after being put into the small glass. How immensely the flies breed and multiply during the hot season is well known and _ illustrated herein—each of the small creeping “worms” on the photo representing a future fly. I had prepared the view during an outing and hunting trip to a relatives farm where the entrails of a small cotton tail rabbit were purposely hung up on a board to attract the blowfly. Tt was in hot summer time, and hardly had an hour passed when the entire ‘intestines and the board itself swarmed with blowflies and others of the pestiferous insects. Fly eggs-and living 'flyworms were soon present by the: millions,. and the photo seen herein was taken on the second day with a close focusing lens and a Bausch & Lomb extension camera, showing the uncountable swarm of living fly worms. Had this same board with the rabbit entrails been properly screened not one of these fly worms would have been presént. Now, this also gives us a good lesson in how to destroy a fu- ture fly scourge in its incipient stage—simply by pouring a quart -of boiling water on such masses of blowfly worms and eggs of flies. In camp also, this method of putting a piece of entrails,. some rotten cheese, or meat, dead fish, etc., ‘to a place outside of camp, but near same, will attract all or most of the flies in the near vicinity and keep them from molesting the campers. -Chief Entomologist Howard, in ‘his admirable works on_ insect life, states that the. period of development of the fly ova were found to be about as follows (in the climate around Washington, D. C.): ‘Egg from deposition to hatching, one third of a day; hatching of larvae to first molt, Myriaps oF Live Larval FLIEs (Maggots) and-Eggs Deposited by Swarm of Flies on Entrails of Rabbit (One-half Natural Size). : : one day; first to second molt; one day; second molt to pupation three days: .pupation to issuing of ‘the adult, five days; total life’ round, approximately ‘ten days. 30 TEXAS NATURE OBSERVATIONS AND REMINISCENCES.

The mouth parts vary considerably in different species of flies; the common housefly, and as seen on the microscopic photo above, being void of special knives and daggers, but supplied with a long tongue or suction tube (1 and 2 on photo.) This tongue of our common fly species is wonderfully composed of a network of delicate absorption tubules (at 1) which during the act of feeding is supplied by aid of the muscular and very flexible neck part of the tongue’s body (at 2) and communicates at the inner base of the flies head and thorax with the stomach. ' The eyeball of the common fly consists of numerous prismatic segments (4) which vary but little in various fly species, though some show more or less: arranged lense ‘segments. wets : “ In the vicious fly species these lense segments seem to be more of ‘a cubic formation; however, they vary slightly in appearance during ‘microscopic and photomicrographic reproduction—according to the an- ‘gle of light reflex applied to ‘Wluminate such otherwise invisible objects. ‘In the common housefly, as stated, the tongue’s suction appara- tus consists of numerous hair-fine capillary tubules arranged in spiral- shape at the apex or lobe of the tongue with which the fly sips its food and absorbs it through these delicate capillary loops. In some of the vicious prairie flies and the cattle fly there exists a combination of such suction appar- ati—besides the tongue with which the fluids are aspirated after searifying their victims with their powerful sting implements. Some Rare Prairie Flies Our ‘Texas prairie conceals a large variety of more or less vicious fly species among which the so-called humpback fly and ' «the horse fly will be considered here. ed ; One of the prairie fly pictures peculiar fly species which, in one way also, is a useful fly, as it attacks and destroys wasps and other vituperous insects. This fly has‘ somewhat the general ap- ‘pearance of a wasp itself, . but it has such peculiar and characteris- tic anatomical arrangements that I am sure these insects belong to the fly family, for these reasons: First, they have the same number of haired feet, with the characteris- tic footclaws and footpads, and “ shows same in the act of carrying -- its victim—a black wasp. Among the numerous and various -- types of prairie flies, for instance. there exists a peculiar and not generally known type of a most 32 TEXAS NATURE OBSERVATIONS AND REMINISCENCES. secondly they have about the same netwings and eyes—the latter of a greenish color and of the same prismatic and cubic arrangement of the lens segments; and third, the mouth parts have a cimilar anatomical arrangement as the vituperous horse-fly species. The . most prominent characteristic of this fly, however, is the peculiar humpback-like thorax, which pro- trudes considerably over the balance of its body. In flying, these flies make a humming noise with their wings, and they are exceedingly swift in their flight, flying however only a short distance, and always with aloud buzzing noise, which is suddenly cut short when they alight on the ground or brush. During a hunting trip in the lovely Leona Valley and also at the Olmos, north of the romantic head of the river, some years ago, the writer first encountered these insects; and one in particular attracted my attention, as it carried a large black wasp in its claws dur- ing its flight. I followed. it a short distance, when it lit on a sunflower bush, and on closer Vicious Prairizg Fry Witu Its Victim, A Biack Wasp. (Normal Size from Nature) inspection it was seen that it had perforated the wasp's abdomen with its long proboscic implements. Being supplied with some chloro- form, a few drops gradually made the insect loosen its hold and drop to the ground, still having the wasp in its clutches; and, after bringing this specimen home, I prepared a photo view of it, showing also the captured wasp beneath it, though the feet were somewhat relaxed and the mouth daggers of the fly also retracted— placed in normal condition.

After the above humpback-fly had been captured and _ photo- graphed with its victim in its clutches, I prepared a photomicro- graph of this fly’s suction and stinging implements.

They scarify the skin and bore down to the blood capillaries until blood oozes in streams from the wound. Our prairies also harbor among other such vituperous fly species a very large, jet b'vck fly, about the size of a cockroach. It, however, is not as numerous and otherwise conspicuous as this fly and the common prairie cattle or horsefly, but it occasionally attacks cattle and horses, and it is supplied with a. number of fearful looking knives and daggers at its mouth parts, and which the insect plunges into the hide of the cattle, causing tke blood to ooze freely from the large scarified wounds. Having captured one such fly during an outing in Medina County some time ago, I prepared a photo-micrograph of the stinging implements of the fly, showing a-number of sharp-edged knives or lancets and dagger-like cutting implements, with a main central suction tube with which this insect aspirates the oozing blood of ani- mals, after scarifying the skin with the other sharp instruments which resemble those of our com- mon prairie horsefly.

The stinging implements of most insects, in the inactive state, are concealed in a hollow sheath along the base and interior part of the proboscis, which comprises the flexible suction tube or tongue, in some insects. - When in the PHOTOMICROGRAPH OF A Mosguito’s Heap AND STINGING IMPLEMENTS : act of stinging the needle-pointed daggers are separated from the hollow sheath and, through muscu- lar action at the base parts and rythmical motions are gradually pierced through the skin up to the, capillary layers, when blood is liberated and absorbed through suction. The original photograph of a mounted mosquitoe’s mouth parts shows one of the daggers inside the central sheath, and two slightly curved daggers outside of same. The knoblike end part of this broad, hol- low proboscis is jointed at its lower part, and consists of two hairy pads, which is also set in motion by the mosquito during the suction act, and serves to accumulate and ab- sorb the blood particles. It is quite well known that a variety of insects, in particular blood sucking insects, are liable to transmit morbid tissue-pro- ducts and pathogenic micro orga- ism upon man and animals. This is the case with some species. of flies, which can transmit anthrax _bacilli, after feeding on some such diseased animal, and produce the malignant pustule; and the horsefly with its powerful developed mouth- parts of daggers and lancets, scari- fies the thick hide of animals until blood oozes from the wounds, and these scarified places often suppurate later on, and are then infested by other insects, especially the blowfly, which deposits numer- ous eggs, from which the screw- worms develop; or the small gnat-. flies, and mosquitoes, feed on the suppurating surfaces, trans- mitting pus and blood corpuscels, © etc., upon other animals or man,— for instance, opthalmitis, etc., when coming in contact with the conjunctiva of ‘the eye.

In former years it was impossible to have a good nights rest on account of the mosquito pests throughout the warm summer months—up to late in fall; but, since the oiling of stagnating waters and breeding places of the mosquito have been inaugurated and especially also the oiling of streets, the mosquito pest, and in fact, all sorts of annoying insects have been driven to outside haunts, as it is simply impossible for such insects to with- stand the odor of oil. Inhabitants along oiled streets in particular, corroborate this, and they are relieved of a great annoying insect burden since .the city’s streets have been subjected to occasional oiling along the carlines, etc., and the terrible dust nuisance is also thereby abated and the streets put in a better trafic condition. ‘STINGING APPARATUS (Suction Tube and Dagger) of a Full Grown Mosquito 36 TEXAS NATURE OBSERVATIONS AND REMINISCENCES.

When once perforated with their powerful mouthdrills, the small reverted hooks of the boring- machines cling to the body tissues like a leéch and only the forcible tearing off of.the tick’s head lessens the excrutiating pain these pests inflict. The original microscopic illus- tration herein of our common wood- tick exposes the powerful boring, cutting and suction implements of a young tick, considerably magnified. _ With these three strong, boring instruments the tick bores, cuts and dilates the scarrified tissues until blood oozes, and the entire boring machine is inserted down to the base parts of the head, at the same time the smaller and broader cylindriform suction in- strument (seen on the photo) serves as the main suction and absorption apparatus of the tick with which it sucks the blood. This boring and cutting act into the skin is very painful, and the riveted hooklets hinder the boring apparatus to be re- tracted and usually is so tightly entangled within the tissues that only by force the tick’s body can be removed—usually leaving the entire mouth-parts and the head of the tick inside the skin. The Texas Cattle Tick and Eggs Under Microscope It is hardly conceivable to the casual observer how immensely the cattle tick really propagates but a mere glance at the photo- engravings herein, at once ex- plains the matter. Through courtesy of a farmer friend at the Olmos settlement, Anton Krug, the writer had oc- casion to peruse a few private ob- servations regarding the interest- ing development of the pestiferous cattle tick, how it breeds its eggs and how they develop into the . mature insect. Some years ago, Mr. Krug had gathered trom his cattle, during the months of December and Jan- uary, numerous cattle ticks in a small perforated box, and some of these I preserved in a plain small pill box, partly covered with cot- TEXAS NATURE OBSERVATIONS AND REMINISCENCES, 37 ton. This was January 18, 1910, and six days later, on examining the ticks two of them had hatched myriads of pinhead size eggs of oval or rounded shape and red- dish brown color and of uniform size. These er-~ were conglomer- ated together like a bunch of grapes and hundreds of them were hatched by a single tick in a few hours and the photo-reproduction of this tick seen herein, with a portion of the myriads of tick eggs it had deposited a short time before, gives us an idea how im- developing, and on February 20, a few of the latter specimens were again mounted on a slide glass, and a microscopic photo plate prepared. This view shows how the eggs progressed developing in the meantime, and how the cellu- lar and other elements of the egg contents developed into a separate oval-shaped body—the future cat- tle tick—these embryonic bodies, of course, still being under de- velopment, until the advancing warmer weather was to eventually develop all of the embryos into _ Texas CaTtTLe TICK, MaGNIFIED SEVERAL TIMES AND Ecos Ir Larp 1n CONFINEMENT. mensely these ticks breed. The tick, with its eggs on this view, is magnified about five times, show- ing the tick on its dorsal side, with the surrounding glistening eggs. | Being now more interested to note the further development of such eggs, numbers of them were ‘mounted in an artificial blood ‘preparation (bovinine) and_ gly- cerine and, though observed dur- ‘ ing .cold weather we had at the time, the eggs slowly progressed the mature insect. These developing eggs show how the outer egg-shell—its cal- careous environments—has separ- ated from the inside delicate cgg membranes, inside of which the developing tick embryo is snugly imbedded. When examined several days after the first crop of eggs is laid, the original fresh egg shell assumes a darker color, nearly black, from accumulated caleare- ous and other matter, but later 38 TEXAS NATURE OBSERVATIONS AND REMINISCENCES. on much of this calcareous outer shell is absorbed by the growing embryo. Some of the eggs were disintegrated through artificial means or partly dissolved in the preserving fluids in which the eggs were mounted for microscop- but in this case they. were about three times larger than when first: laid by the old tick, when they were more of a yellowish r. G, glit- ttering color.

The original size of these same tick eggs is not much larger than an ordinary small sized pinhead, keeps growing and absorbing its eggs elements, assuming the shape and consistency of a miniature rub" ber ball, with several indentations along its dorsal and abdominal side, and gradually eight legs form, when, after another cycle of TEXAS NATURE OBSERVATIONS AND REMINISCENCES, 39 shedding process, the maturing tick shows three pairs of legs on its clumsy body. The suction ap- paratus of this tick also develops early and serves the insect, after crawling on its host to work its way into the tissues of the ani- mal’s skin,when it sucks its body full of blood. It can be imagined how the poor cattle suffer from these minute leeches when thou- sands of these insects are adhering to the cattles’ body and sucking the life juice out of them. The cat- tle thereby become anaemic and sick, with high fever and diseased inner organs, and often die by the wholesale—all on account of these minute bloodsuckers. The enormous loss to cattle breeders by these ticks may best bé seen by consulting the official reports of the United States De- partment of Agriculture, and I take the liberty to; append herein reports of W: D. Hunter, Shreve- port, La., and Dr. J. R. Mohler of the Bureau of Animal Industry of this department. They have made most careful, comprehensive esti- mates of the losses caused by ticks. The following summary is taken largely from their writings: 1. Loss by death from disease jin young animals and those re- moved from temporarily tick-free localities (as, for instance, all cities,) to places where they, be- come infested. The enormous loss under this heading will be under- stood when it is recalled that ev- ery bovine animal in the tick area must suffer an attack of fever if it becomes infested with ticks. In an instance that came to the at- tention of the writers, 39 out of 40 calves dropped ina city dead of tick fever when removed to an infested pasture. 2. Loss in weakened condition and stunted growth caused by the fever. 3. Loss by gross tick infesta- tion. At the present time (March 1907) hundreds of cattle in South Texas are dying from gross infes- tation resulting from a mild win- ter. In extreme cases, Mr. May- er estimates that as many as 200 pounds of blood may be withdrawn from the host during a single sea- son. This makes a gain in weight impossible, even in the best of pas- tures. Morever, Prof. H. A. Mor- gan and other observers believe that gross infestation and the con- sequent general debility induce acute attack of fever even in ani- mals ordinarily immune. 4, The tick makes hazardous the importation of pure-bred cat- tle. This prevents the upbuilding of Southern cattle and at the same time largely deprives the North- ern breeder of a market that he should have. Moreover, the in- ability of the Southern breeder to exhibit his stock in the North and of the Northern breeder to ex- hibit his in the tick area ig a handicap, the importance of which will be readily seen. 5. The necessary restrictions in the shipping of Southern cattle al- so handicap the breeder and af- fect the price: 6. The maintenance of the quarantine involves considerable annual expense for the protection of the cattle owners north of the line. 7.. Minor losses may be grouped as follows: (a) In Texas, espec- jially, the tick induces the attack of the screw worm fly (chryso- myia macellaria Fab.) ; (b.) there seems to be, as pointed out by Mr. Mayer, a considerable interference with the fecundity of the infested cows; (c) the railroads are put to'the expense of disinfecting cars and maintaining separate pens and the stockmen to the expense of dipping—items which react on the price that Southern cattle bring. ‘All the losses that have been mentioned total approximately $100,000,000 each year. At present the loss, as indicated by Dr. Moh- ler, amounts anually to at least 10 40. TEXAS NATURE OBSERVATIONS AND REMINISCENCES. per cent of the value of the cattle. The quality of the animals is low- est and the loss is greatest in the. regions where the natural condi- tions without the tick should pro- duce the finest cattle with the least loss. But the damage may be better expressed by the state- ment that the tick makes profit- able production practically im- possible in the South. Any suc- cessful system of agriculture must rest upon a diversification of crops, and this, in turn, depends upon animal husbandry to main- tain the fertility of the soil. There- fore, until the tick is eradicated or placed under control a rational system of agriculture in the infect- ed area is out of question, and that achievement would mean al- most as much to the North as to the South. The Hog Louse Among the hundreds of various types of animal lice the above louse of a hog takes the cake. Note the fearfully large and curved claws of each leg with which it molests the animals and often causes ulcerations and general sick- ness. The specimen was gathered at a Texas farm, the louse ac- cidentally crawling. along a fence- rail. It is considerably magnified and represents a nice specimen of photo reproduction of that par- asitic creature. THe Hoc Louse The New Human Parasite of the Sarcoptic Tribe In April, 1896, when acting as city physician of San Antonio, a peculiar chronic disease in an aged person, (Doctor R: ) came to my notice through a friend, Dr. Wn. Fleming of Georgetown, Tex- as, who was attending the case. Concerning the symptomatology, Dr. Fleming -kindly favored me with the following data: ‘‘ About eight months ago my patient be- came afflicted with the disease and has been a great sufferer ever since. The disease appears with small papules here and there, from a pale to firey red, and at times under treatment will seem appar- ently well, but on application of ointments or lotions reappears in greater or less numbers and larger or smaller lesions. The disease is not attended with itching, but when very red has a slight burn- ing sensation. The dnimaculae, it seems, on maturing, emerge from the skin, in some places seem to discharge germs covering a space more or less dense from a half to two inches in diameter. The various remedies I have used have caused many of all sizes to come to the surface, some bore under the skin again, and although IT have picked off thousands, I have never seen one move. One of the annoyances to the patient is their crawling on the skin. Their bite is much like that of a flea or a chinch, and often so rapidly is it done that the mite will bore in before you can pick it off with the point of a knife. The bites and pimples never suppurate nor ex- ude serum. “T have given six months of study and investigation to the dis- TEXAS NATURE OBSERVATIONS AND REMINISCENCES. 41 ease and have found nothing in our medical literature which at all resembles it. I have carefully watched him, so that he could not deceive me nor anyone else. Be- sides, he is too anxious to get well for a malingerer.”’ The doctor and also his patient have forwarded samples of the material gathered from the sick man‘s body for me to examine mi- eroscopically. After proper mount- ing (in glycerine and dilute acetic acid also, in Canada balsam) the main ingredients seemed to be in- dressed a letter to Dr. Fleming, and received the following an- swer: “‘T assure you that every par- ticle of the samples I sent you eame from his body. He never has taken a sand bath; he always washes himself in hot water, as it gives him more relief. I have watched him closely for six months and have tried every known remedy without success.

In a number of these slides I noticed several peculiar microscopic mites, and in few instances larvae and casts of these parasites. Being somewhat suspicious, I again ad- on him by washing or any appli- “eation.' ‘When I use vinegar on him there will come out on his body more sand or shells, and in the morning his body contains more than in the daytime, keeping him awake through the night. I have scraped regular ‘barnacles formed by the insects at night from between his toes and creases of the arms and elbows,’’ etc. After these statements I gave the matter closer attention, espe- 42 TEXAS NATURE OBSsrVATIONS AND REMINISCENCES. cially regarding the parasites found, as, from first appearance it appeared to me that the mite was not a species of the common acari, found occasionally in de- caying material or detritus, or fruit, vegetables, cheese, flour, ete., but that it was a true sar- coptes—not, however, the common itch parasite of man. In this onin- ion I was sustained by Dr. A. EH. Boeckling, an expert on parasitic mites, and also by Prof. Allen J. Smith, Pathologist of the Galves- ton University. Both of these gentlemen had taken a great in- terest in the seemingly trivial matter, which, of course, could on- ly be settled by a close microscopic examination and comparison with other similar mites. Having se- cured one especially fine specimen among the cuticular scrapings, I mounted it separately from the other remnants and forwarded it to Prof. Virchow, after having it investigated by our Smithsonian experts, etc., but never received a reply from Berlin (perhaps it had not reached its destination). This mite is of the size of the common itch mite, hardly visible to the naked eye, of yellowish- brown color, supplied with eight legs, jointed, and the pedal ex- tremities are supplied with a suck- ing disk—characteristic of the sar- coptes or itch-parasite. The eight legs are decidedly thoracic, not marginal, and the specimen pre- served was a male one—the sex found being considered by ex- perts as of rare occurance. In comparing this mite with the com- mon cheese mites and fruit acari, our mite shows the legs, jaws, ab- domen and bristles more fully dev- veloped, the latter closer to the base of the abdomen and larger and thicker. As seen on the photo-reproduc- tions, I succeeded in making sev eral microphotos of the parasite, in different stadia, and also of the larvae. The latter is six legged; the body and legs were semitrans- parent and dotted throughout. I have not encountered any such larva in microscopic mites before. The Smithsonian experts also de- elared it to be the larva -of the parasite under question: Prof. Allen Smith in October, 1896, had given me a very inter- esting report on sarcoptic mites in general, and of our acarus in particular, and I only include here the following points: *‘ I have been looking up all the data I can get hold of in my endeavors to identify the dermal parasite. There seems to me to be no doubt of the parasite being an acarus. The mode of articulation of its legs, the fact of its having five divisions to each limb, its choli- form or pinchers-like jaws in my mind place it surely among the sarcoptides. (Here follows an ex- haustive explanation of the five tribes of the sarcoptes family, having used as euide, Meguin: (‘Les Parasites articules.’’) The five tribes are: Sarcoptes detri- colles, S. plumicoles, 8. cysticoles, S. glicicoles and S. sporae.** The specimen in hand cannot belong to the first tribe. It differs in being provided with a somewhat rugous integument, in having un- equal limbs, and, I believe, dis- similar in having a distinct cleft in the abdominal extremity. It is not to be mixed up with the bird- infesting sarcoptes (S. plumicoles) the latter has all its legs well de- veloped and never even tending to be abortive (as in the last pair of R’s parasite) and never produce painful or itching sensations (by some poison in its bite.* * * I would place R.’s parasite, from its shape, its somewhat striated coat, its undeveloped hind pair of legs, and its power to produce itching, among the true itch-sar- coptides. * * * I believe the R. parasite to correspond with the genus of chorioptes. As to species. I am still uncertain, but believe it TEXAS NATURE OBSERVATIONS AND REMINISCENCES. 43 to be C. ecaudatus. * * * I see no hairs on the third pair of legs (they are present on this parasite, but were unclear or not visible on the microphoto. R. M.) and only two clearly on the abdominal bor- der. I cannot make out the dor- sal plate, etc., since the photo- graph from which I must take my points only gives the ventral sur- face. * * * Aside from these, the deseription suits well, and if these differences are real I believe that at least the genus is correctly fixed, and the species perhaps a new one.”’ Dr. Boecking called to my at- tention that, if the above diagnosis of the parasitebe applied to a mature specimen, it seems, indeed, to point to a cheiroptes, were it not for the fact stated in regard to the position of the extremities, which are thoracic in our mite and not marginal. I have compared our parasite with a number of mites of old fruit and cheese, and it diffeys in being smaller and ‘‘bolder’’ ap- pearing acarus, and the endpads of the legs, on high-power exami- nation, showing a stirrup-shaped diseus or sucking-cup. This dis- tinguishes the sarcoptes from sim- ilar acari. In microphotography, -of course, only such objects and outlines can be copied as come un- der sharp focus of the lenses of the microscope, especially in making a microphotocopy of such a minute -object as our mite under a very high magnifying power. For this reason the outlines of the terminal parts (sucking-cup) of the legs are not so sharply outlined as the rest of the’parasite’s body. This case of parasite disease seems to be unique in many par- ticulars regarding etiology and symptomatology. With the excep- tion that it was noticed over near- ly the entire body, the symptoms, as stated by Dr. Fleming, would distantly tally with those of the common itch sarcoptes of man;. but, as noticed, had patient the usual itch plague, there certainly would have been found remnants of the itch parasite and its larva, ova, etc., and then, the itch disease is easily amenable to rigid anti- parasitic treatment. The speci- mens or remnants from scraping of the skin sent to me were, of course, in a dried-up state; they formed a yellowish-brown, granu- lar powder, showing cn proper ex- amination, numbers of cuticular cr more deeply-seated remnants, ca- pilli (sparingly), calcareous rem- nants, some granular (apparently hemorrhagic) detritus, shed skins of microscopic mites, and the par- asites, either entire, but contract- ed, or in remnants (partly incrust- ed). The latter were dead aca- rinae, and the one specimen, now under question and _ illustrated, had its legs contracted when first found, but, under coverglass pres- sure, the legs were gradually _ Spread out. In conclusion, I beg to call at- tention to the fact that an article on this subject has been published some time before, but the same was full of typographical errors and the photo-illustrations of the parasite were not as good as de- sired. It is for these reasons that’ the matter is hereby again brought before the profession. I may also ‘state that I had sent the article (in pamphlet form) to a large number of experts and medical in- stitutions here and in Europe, and received from none any data con- cerning a similar parasite. The authorities of the Zoological Lusti- tute of Genoa, Italy, have sent me ‘in return, some literature on mi- eroscopie mites, with illustrations, but no such mite is mentioned. Whether, in our case, the parasite had been implanted accidentally on the patient from some animal infested with a sarcoptic disease, or from some other unknown source, of course can only be con- jectured, but the fact remains that . 44 TEXAS NATURE OBSERVATIONS AND REMINISCENCES. the entire case, as above described is unique, and the parasites found are some uneatalogued sarcuptes species—in my own humble opin- ion at least. The cuticular serap- ings, as stated, contained 2 vast variety of superficial cuticular ab- rasions and deeper-seated pro- ducts, especially of the follicular . system of the derma, and among these were remnants of the para- sites, some seemingly incrusted and surrounded by a caleareous encasing. The sarcoptes species in differ- ent animals differ from the one under consideration in many re- spects, and it is for this reason, and in particular, also, as the par- asites, larva and remnants of same etc., were found in scrapings re- moved from the body of man, that this is such an interesting study, even were there found no parasi- tic vestages, : Referring to the microscopic illustrations herein, the photomi- erograph, Fig. 1, shows how immensely this parasite is magni- fied— compared to the smallest hardly visible dot in Fig, 3, and it shows the bold outlines ,of the legs, body and _headparts plainly. Fig. 2, represents the cast off remnants of the larval state of this mite. Fig. 4, shows the general appearance of the raw cuticular material sent for examination ; and the large dot in Fig. 3, shows the average size of the globular bodies expelled, some of which revealed the encased lar- val parasite. Some Observations on the Echinococcus Disease (Bladder Tape Worm.) Of the Texas Jackrabbit ‘in Particular. The near relationship of the echinococecus parasite of man to the same parasite disease in ani- mal, and the question often asked of the writer whether this disease was the cause of the widespread and common tapeworm pest, in- duced me to investigate this inter- esting matter thoroughly in the following paper published some years ago in a medical journal. There is no doubt to me, as to oth- ers who have given the matter a close consideration, that there oc- cur cystic tumors in man which are really echinococi in advanved and degenerated state, but were overlooked as such for want of a microscopic examination. My pa- per, therefore, and the photo-mi- crographs of the echinococeus par- asites, which I prepared from mi- eroscopic testings, I hope, will be welcomed in throwing a little more light on the matter. Besides _ the more common and well-known species of tape-worm—the taenia mediocanellata, taenia solium and bothriocephalus latus—there oec- curs in this climate a very minute and but little known taenia, the embryonic or larval state of the bladder tape-worm, which, in ani- mal, infests with narticular pref- erence the prairie rabbit; and to hunters it is well known that among the rabbits it is nearly ex- clusively the large so-called jack- rabbit which is often infested with peculiar tumor-like protuberances or cysts in different parts of its body, and that, especially during a protracted drv season, a perfect epidemic of the disease exists among the large prairie rabbits, and that the small bush rabbit is nearly exempt from the disease. In consulting a number of works, medical as well as veterin- ary, I find no mention of the echi- nococcus disease among the rab- . bits. It is a noticable fact that, TEXAS NATURE OBSERVATIONS AND REMINISCENCES, 45 while this parasite in other ani- mals invades nearly all the inter- nal organs, the echinococeus tu- mors in rabbits, with but a few exceptional instances, have been found with particular preference in the muscular system, especially in the muscles of the lumbar re- gion and the muscles of the thighs and ribs. A common idea prevails among the laity that these tumors from which they generally start to develop and multiply or mi- grate to other parts of the body. During their growth the cyst sacs protude below the skin and they can easily be felt in the shape of roundish, oval or flat, single or conglomorated, and elastic tu- mors, from the size of a marble up to a child’s head, thereby giv: ing the different parts of the rab- Tue AutuHor (At time of writing of the article some fifteen years ago) are some sort of ‘venereal dis- ease,’’ ‘‘ulcerations,’’ ‘‘grub- worm,’’ ete. I had occasion to ex- amine a great number of cystic diseased rabbits, some of which, in rare instances. showed over one half of the entire body covered with cysts, reaching along and be- tween the muscles of the lumbar and thoracic region down to the abdominal and thoracic cavities, rabit’s anatomy a very deformed appearance. On dissecting these tu mors, in advanced cases, a firm fibro-cystic membrane with the in- ner or endocyst, similar to the py- ogenic membrane of some abcess cavities is noticed which is filled with some albuminous like or gela- tinnous fluid, and each separate eyst and even surrounding parts of such, contain myriads of small, 46 TEXAS NATURE OBSERVATIONS AND REMINISCENCES. whitish, hard kernels not larger than a pinhead. These kernels, if compressed between two slide glasses and examined with a mag- nifying glass, show an oval or roundish worm-like body with a short and rather broad neck (in its contracted state) and a mi- nute head. If put under micro- scopic examination, it is at once apparent that these bodies are some species of the larval state of appearance of these minute taenia bodies plainly. In general these echinococei of rabbit correspond to the echinoccoccus parasite of man, only that in man, while it is found in nearly all organs, but especially in the liver, it is a para- site that, as stated, nearly exclu- sively infests the muscular sys- tem of the rabbit—similar to the trichina spiralis of man, arid some species of cysticerci—only _ that Eccurnococcus Disgasz 1n Rasair, Section of Lumbar Muscle Infected with the C ysts1,2and3.

The echinococcus tapeworm in man is described as a very small taenia, with only four or five joints. TEXAS NATURE OBSERVATIONS AND REMINISCENCES. 47 The most accepted theory re- garding the migration of the echi- nococcus into the substance of the liver in man is this one: that after the echinococcus embryo is set free in the intestines from the food or drink containing the ova, it starts on its migration into the portal vein, and through that source into the liver. Besides the portal vein and its hepatic branch- es, some authors claim the gall tered, and in Pepper’s system of medicine on echinococeus of the liver, mention is made of an oc- casional anomalous development of the multilocular parasite, which from its resemblance to colloid cancer, was supposed to have this character. Peper states: “‘Its re- semblance to colloid cancer is the more striking because of the tend- ency of the interior of the mass to undergo degeneration, to disinte- Oe Soe Hzapparts witH HockLets IN THE CENTER AND SUCTION CUPS OF THE Eccuinococcus Parasite IN Rassit (Highly Magnified.) ducts and the lymphatic sinuses as the main source of migration into the liver substance, remnants of the narasite having been found within the lumen of these vessels.

An echinococcus multilo- cularis tumor is of almost stony hardness; it has a very dense fi- brous structure, intersected by ca- vities with thick gelatinous cavi- ties,’’ etc. I have myself not en- countered just such conditions as the above mentioned in examin- ing echinococecus conglomerations in the rabbit, hut I do recollect many years ago having removed: 48 TEXAS NATURE OBSERVATIONS AND REMINISCENCES. an enormous and nodulated cys- tie tumor of one of the’ ovaries, showing precisely the same condi- tions, but the case undoubtedly was one of cystoma or cystic de- generation of the ovarian follicles; it weighed thirty pounds, the lady living yet, in good health. It is quite well known that in these cent. of the cattle carry the echi- nococcus, and that in some other countries, Iceland for instance, aceording to Kuchenmeister, the echinococcus disease is so wide- spread among man that the native physicians there in 1872 reported one-eighth of all the diseases oc- curring there as having been A S1IncLE EccuiNnococcus with HooK.etTs IN CENTER OF UPPER Bopy.

The main cause of the disease in Iceland, according to Kuchen- meister, is attributed to the many dogs kept there; these and the warm drinking water being re- sponsible for the enormous spread- ing of the disease in man, as the dogs devour the cystic deposits which are carelessly thrown about the yards, and the people are reported to sleep with the dogs in one and the same hut in many imstances. In {the case of our jack rabbits, undoubtedly the same process of propagation or auto-infection takes place, and it is a noticable fact that when our prairies are covered with an abun- dance of luxuriant green grass, cystic diseased rabbits are rarely met with; as soon though as a prolonged droughty season pre- vails, such as the present one, and the rabbits are compelled to eat nearly directly from the ground, they also perhaps devour numbers of the echinococeus eggs or taenia embryos, and the prairie is thea found to be covered with diseased rabbits. The wolves, and perhaps sheep also, undoubtedly . spread the disease. The wolves kill and eat the remnants of the Ciseased or killed rabbits and deposi: the ova or embryo in their manure. It is an accepted fact by au- thorities (Leuckart, Sicbold, Vir- until they. chow, Kuchenmeister, and others,) that the echinococcus is a sort of cystic tapeworm and the embryo state of the taenia echinococcus— the same as the cysticercus cellu-, losae is related to the taenia so- lium. Experimental tests with echinicocci of man introduced into animals have proven negative so far, but, acording to Niemeyer’s pathology, it has been proven that animals fed on echinococci of an- other animal developed the taenia echinococci in the intestines of such animal experimented upon. The immense proliferating proper- ties, each vesicle containing, ac- cording to Friedberger (Patho- logy of the Domestic Animals), as many as thirty scolices, and in one echinococcus alone as many as a thousand; its very minute size and its vitality and tendency to mul- tiply in the rabbit faster than the same species of parasites in man, readily explains the immense and wide-spread infection in the rabbit and canine’ species. Luckily ‘though, we Texans are not living in Iceland, and our advanced civ- ilized methods of preparing and cooking food, our protected and wholesome hydrant drinking wa- ter, and also the abondonment of eating raw meat has cut a great figure and added immensely in the prophylaxis against all sort of par- asite disease, and we owe it to our good housewife and hotel cooks in general that such narasite disease as echinococcus in man is rather a very rare occurance in Texas. Among Texas cattle.and sheep this disease also is hardly known, as far as I am informed, and _ the question naturally arises: Is this parasite in our rabbit of the same _ Species as the one that produces such havoe in some other coun- tries? That, from its description and histological appearance, this embryo-coceus of the jack-rabbit is near related to the echinococeus of man, there hardly can be any doubt. At any rate, though, it 50 TEXAS NATURE OBSERVATIONS AND REMINISCENCES. has no relationship with the wide- spread and common tapeworm pest, the taenia medioconellata and solium, it is a parasitic disease sui generis as far as the Texas jackrabbit is concerned. | The par- asite, therefore, does not produce any tapeworm in man, as some persons are led to believe, and good cooking and frying will de- stroy the fins or cysts in the meat of any rabbit; but, of course, it is better that such infected rabbit meat should not be used at all. In order to hear the opinion of other professional gentlemen on Dr. FERDINAND Herrr. Late Veteran Physician and Surgeon of San Antonio, and Nestor of the Medical Fraternity of Western Texas, (From life size and life’ like painting.) the subject, I addressed some years ago, a few lines to Dr. F. Herff, (who by the way, has had an immense amount of practical experience in this line, also), and the venerable old gentleman kind- ly forwarded me the following re- ply on the subject: ‘‘The taenia echinococcus is a verv small tape- worm with well-developed head (scolex) and three or four, joints (proglottides). It lives in the in- testines of the dog, and is not so very easy to find and the roundish appearance of the body, which at first sight looks like a small nem- atoid worm. Only by examining it in water, by which the intestinal _ mucus is washed away, and with a common loupe you can disclose its true organization. J stumbled on it during the examination I made on a dog which I had fed with trichinotic sausage, while hunting for intestinal trichinae. Afterwards I found it many times in the intestines of many dogs which were killed by the police during the rabies scare and fur- nished by Dr. Petterson, then city physician (in 1873). The embrvon- ic state in the rabbit has been known to me long ago, as it is also to many hunters who have shot rabbits, and, in consequence, cre- ated a disgust in people to eat them. The embryo lives in the peritoneum and between the mus- cles in the connective tissues, and is a true echinicoccus—that is, a scolex—which multiplies in its cystic surroundings by spzrout- ing or budding anl ereating new scolices. In that respect it differs from cysticercus, which lives in a solitary cyst, and to which family the taenia solium, mediocanellats, etc., belong, while the botrioceph- alus latus develops free in water at first, but probably enters then a host (cistern, sink or waterpool) and then is developed in the body of man, as botriocephalus. These of course, will not cause to man, much _ less _ echinococcus which is only produced by the in- gestion of the eggs of the mature animal, the taenia echinococcus which came from the dog that had eaten infected meat from rabbits, or through wolves or foxes who also harbor the mature: parasite. Insofar the eating of infected rab- bit meat is onlv disgusting, but will not produce taenie. The dog however, is the evil-doer, and so the fondling and kissing’ of. lap- dogs or the sleeping. in the same room with dogs is to he avoided. * * * * “T have found the echinococcus TEXAS NATURE OBSERVATIONS AND REMINISCENCES. 51 in man twice in the liver (in one case over two quarts and one quart in the other case) ; between the extensors of the thigh; one in the bulbus of an eye extirpated for panovhthalmitis; once it passed from the bowels of a lady who had often suffered from pain in the liver, but did not show any tumor. My son took a great many echinococcus from the bladder of a child; they were large, trans- parent and elongated. All these specimens I mentioned contained hooklets, and so the diagnosis was eorrect. I understand that Dr. McLaughlin, in Austin, also re- moved echinococci from the vagi- no-rectal cellular tissue. I am sure if proper inquiries were made it would prove to be so. The speci- mens of which you send the photo- graph is a true echinococcus, as ‘the multiplicity of the heads in- dicate.’’ Besides above, I have a few other cummunications on cases of echinococci in man, including one of Dr. R. H. L. Bibb, of Saltillo, Mexico, stating that he had re- moved a cystic tumor. several years ago, situated in the cellular tissue between the ‘‘trapezius’’ and the ‘‘latissimus dorsi’? mus- cles, which the microscope showed to be due to this parasite. The microscopic mountings which I prepared from specimens of diseased rabbits, I may state, were examined by friénds with much interest; especially also in the private bacteriological labora- tory of Dr. Julius Braunnagel. -~ After above had been written, an additional paper on the sub- ject heading this article was con- tributed to the Texas Medical Journal, and I herewith submit the main part of same: These investigations will show that after the development of the premature or embryonic p:rasite of the echindcoccus tapeworm from the ingested ova of the ma- ture taenia, up to the migration, encystment, and snrouting of new embryonic colonies inside the cyst membrane in different parts or organs of the human. and ani- mal system, that all of these par- asites in their most primitive sta- dia already show quite a well- developed head with characteristic suckers and hooklets and after further development, free them- selves from the endocystic mem- brane, although still adherent to its linings and ultimately, after still further development, some of the more mature of these embry- onic parasites isolate themsclves later and free themselves entirely from the other more premature crop, and can then be found in a free state cither near the base of the endocystic membrane or in- side.of the cyst fluid. Something About the Texas Prairie Spider. In his ramblings about the prairie-plains, river-bottoms and forests, the hunter and lover of nature encounters a large variety of interesting arachnids, from the smallest, hardly visible spinning- variety up to the hand-large black or brown-colored and fearful look- ing jumping tarantula. : With its immense area of over 274,000 square miles and sunny clime, Texas naturally’ harbers a ‘large variety of spiders .of differ- ent type and colors; and, al- though the more dangerous types are not as numerous as encoun- tered in the tropical zones of oth- er countries, we have among the smaller variety of interesting arachnids some very vicious speci- mens; and among these the small speckled vagabond’ or jumping tarantula is most conspicuous. For reason of a lecture before the San Antonio Scientific So- ciety, the writer had the pleasure 52 TEXAS NATURE OBSERVATIONS AND REMINISCENCES. to submit a lengthy report on Tex- as prairie spiders and others, con- jointly with numerous photo illus- _trations which are now also re- produced herewith, and the read- ers undoubtedly will recall most of the different tynes they may have met on their hunting trips. These photos are all original, and as seen in nature. As stated, Texas harbors in cer- tain favored localities numerous spiders of more or less vituperous type; but the majority are entire- ly harmless, and many are useful creatures. During summer and especially during the breeding time some species are exceedingly vicious. At this time they prepare their delicate breeding nests either underground, or in hollows of trees, under jogs and rocks and the loose bark of trees, old rotten wood, ete. In gardens they are es- pecially dreaded at this time, on account of oecasionally invading the fruit trees, in particular ba- nanas, grape vines and ripe grape bunches ete. Undisturbed by their many enemies—man and birds and wasps, they are cntirely harmless and in one way useful. In the Is- land of Madagascar, it is well known, the natives gather the spi- der web material of a particular spider species directly from the spider’s spinning apparatus. It is of yellowish-gold color and glitters like silk, and the most delicate and costly fabrics are woven from the silk-like spinning material of these useful insects and there ex- ist special spinning factories in which the natives prepare the most gorgeous silk-like domestic products known in the world. In Texas the most dangerous species known is the small speck- led snider belonging to the ge- nus Letrodactus Mactams and Phydippus Trinunctatus. a small, jet black or brown Tarantula, striped with white, orange yellow or vermillion red specks on its up- per abdomen. These spiders have, camparative- ly, short but powerfully strong fangs and legs, a very large quad- rangular head and thorax, and four to six very sharp eye lenses. They jump a far distance to catch their prey—mostly flies and other insects. The poison of these spiders is contained in a poison receptacle near the headparts, and it commu- nicates in tubules with the small but sharp and curved fangs. The venom is of an oily consistency and even a very minimal quantity produces so severe venom-inocula- tion symptoms that it is consid- ered more venomous, comparative- ly, than the venom of a rattle- snake. The curved venom ciaws can be seen at the end part of the strong mandibles in the form of deep steelblue and glittering pro- jections, and more so if viewed with a magnifying glass. The inoculation symptoms are either of local or of systemic na- ture, according to the amount of venom and the parts inoculated. Generally a severe sting is felt, with inflammation or blisters af- terwards; or the venom is ab- _sorbed rapidly into the blood and lymph current, and symntoms of ‘a severe nervous nature, with pain radiating over the abdonien, chest and spine set in—-as if a band was tightly constricting the — body. In such severe cases vomit- ing spells oceur and the heart centers may be affected——-:ymp- toms similarly oceuring in snake- bite. The medical profession ‘occa- sionally meets with such eases, and I recall a case that happened some years ago which I treated with Dr. Cafferey: A young lady from the Salado settlement was bitten on her leg by one such spider and she suffered excruciating pain and nervous attacks before being relieved under special treatment, and it was over two hours before TEXAS NATURE OBSERVATIONS AND REMINISCENCES. 53 ‘she could be safely returned to her home. In his publications on ;Texas reptiles and spiders, Dr. H. W. Cruse of Victoria, Texas, re- lates the following interesting case of spider bite of the small, Jumping variety by some hunter: ‘*In the month of October, 1865, I was hunting in the woods three miles north of Halletsville, La- vaca County. Thrusting my hand into a blackjack stump, I felt a sharp pain in the back of my hand between the thumb and fore- finger, of my right hand. With- drawing it quickly, I found a spi- der (Latrodactus Mactams) fast- ened to my hand. I crushed it and proceeded with my investigations. In a few minutes my hand began ‘to tingle, like it had been asleep, and a place around the bite, the size ‘of a half dollar, began to discolor. I started for home about one mile away. In the meantime the tingling had turned to a thou- Wuite anv Rep SPoTTeD JUMPING TARANTULA (Magnified alive three times. ) sand needles being thrust into my hand and arm as high as the el- bow and I got sick at the stomach, and when about half way home I laid down and vomited freely. Ar- riving at home, I had another vomiting spell and felt very faiut, and the pain in my arm was going up. There was little swelling in the arm, but the spot around the bite had turned the color of dead . flesh, and the nausea was very great. I secured a horse and start- ed for town, three miles to a doc- tor. Six times in the three miles I stopped to vomit, and when I got to town the intense pricking pain had gone up my arm and around to the shoulder blade. I went straight to the office of Dr. Troup. My eyesight was dim. My brain was muddled, the nausea was intense, and the pain in my hand, arm and shoulder was very severe, and I lost all mental fear of what the result might be. The doctor gave me something which relieved me of all pain and I went to sleep. When I awakened he was examining my shoulder and arm. About where vaccine is generally placed on the arm was another place similar to the one. around the bite, and still another on the shoulder blade. They were all about the same size and color, slightly raised and hard. I was in bed two days. About the fifth day a sharp line had separated the healthy flesh from the diseased flesh at three swollen places, and the dead flesh fell out in a lump, leaving a clean, healthy hole that would hide about two half dollars. I lost flesh and it was about a month before I regained my usual health. I do not know what reme- dies Dr. Troup used.”’ The breeding nest of these spi- der species is an interesting study. They do not dig funnel shaped nests underground, like some of the larger tarantula species or prepare web nests in hollows of trees, like some other spiders, but they prepare a neat, flat, or glob- ular, dense nest in some corner— probably under loose wood or bark of old trees or rotten wood. or in secluded places. of stables and old-fashioned privy vaults. During an outing in the post-oak valley of the Olmos settlement, north of San Antonio, some time 54 TEXAS NATURE OBSERVATIONS AND REMINISCENCES. ago, the writer came across a large broken oak tree trunk, with its bark leosely adherent to the fallen tree. In removing this bark with a stick an interesting scene presented itself. In one cor- ner two large scorpions, with tail erect, were seen, coiled up and ready to strike, and several feet apart two small jumping spiders, with their breeding nest were to be seen. They were both of the deadly speckled type, and the jet black colored variety with its which the spider dwells and lures for some insect that may be en- tangled in this upper web (just as seen in the illustration). A similar rare and rather queer and scientificially interesting breeding nest of a spider is also seen in the photo illustration in these pages, showing a spider’s breeding nest in a large silver spoon. The spoon with its inter- esting contents was handed the writer two years ago by the sec- retary of the San Antonio Scienti- PHOTOMICROGRAPH OF a VERY YOUNG CRABLIKE SPIDER AND Ecc three carmine red specks. It was hidden under the cover-lining of its dense webnest—exactly as seen in the original photo in these pages. In the center part of this illustration is seen the round- ed or oval-shaped cocoon of these spiders, which contained myriads of eggs, and perhaps developed young spiders. The mother spider of this species covers its breeding nest with delicate, yet dense and strong, upper weblining, under fic Society, and later I happened to prepare a photo copy of same for a lecture before the Scientific Society of San Antonio, on Texas arachnids. This spoon, as the il- lustration shows, was nearly en- tirely covered with a densely wo- ven, network cover, and a funnel- shaped breeding nest inside the hollow part of the spoon. We noticed numerous living spiders crawling over the edge of the spoon and along the web-lining— TEXAS NATURE OBSERVATIONS AND REMINISCENCES. 55 -not much larger than a pin head. They were of crab form, hairy, and showed well-developed spin- ing claws and six eye-lenses, on microscopic examination. The il- lustration shows how the mother spider, after preparing the inside funnel-shaped breeding nest— and which contains innumerous spider eggs—artistically spun its delicate threads from one edge of the spoon over the other margin, thus covering the breeding nest which serves to protect the young developed brute as well as to en- tangle insects, which later serve as food. The greatest enemy of spiders rolled around and around, until, after several attempts, it succeed- ed in plunging its sharp stinger into the spider’s body, and it ex- pired at once. After this it car- ried its victim to a nearby hole, ‘ and disappeared with the tarantu- la under ground. The illustration in these pages I reproduced for this article from Harper’s Ilus- trated Journal, as it is a fine and lifelike presentation of this pe- culiar vicious and useful wasp. ~ It is an interesting study to note the breeding cycles of spiders and some years ago, whilst engag- ed in some private entomological research and microscopic study of A Pair oF SMALL PRAIRIE TARANTULAS WITH BREEDING NEsT AND Cocoon 1n Hottow or a TREE Bark. # & is a. fees yellowish-brown wasp. —a, ground wasp.

It was during a hunting trip, in a severe cold winter month, out in the postoak valley of the Olmos, that I ease across thos interesting nest. It was suspended on the 56 TEXAS NATURE OBSERVATIONS AND REMINISCENCES. branches of a dry mesquite tree, with some of the dry mesquite leaves interwoven to a branch at its base.

The spider seldom bites or stings, but should anyone try to catch him, bite he will, and, though not venomous, his jaws are as powerful as a bird’s beak. ¢ Cocvoon oF a LARGE AND BEAUTIFUL PRAIRIE SPIDER WITH MyRIADS OF THE YOUNG Broop, SusPENDED BETWEEN Drizp BRANCHES AND LEAVES OF THE MESQUITE TREE large brown lycosa tarantula.
