INTRODUCTORY. WHAT are " swimming-plates " ? is the natural inquiry of a stranger to the system, and its answer may be prefaced by an extract from the manufacturer's circular describing their aim and object, or what they effect. " These ' Plates, and ' Flippers ' give marvellous float power, diving power, endurance, and speed to swimmers. "They enable an average swimmer to carry from forty to fifty pounds' weight of iron, tied round the neck, while on the other hand, they enable him to dive, from surface, and swim under water, wearing an inflated life belt. " They enable weak swimmers to go long distances, by the saving of strength resulting from reduction of the ' slip ' of ordinary swimming ; and, by the grasp of water they afford, they increase an average swimmer's speed by about fifty per cent. " The wooden plates supply about seven ounces of buoyancy, and so allow of motionless rest on the surface, without any constrained breathing as in ordinary floating. 14 Plate-Swimming. "In short, they make swimming easier, pleasanter, and more effective" It is the duty of the writer to describe the " why " and the " how " of this predicate, always allowing that the best and most prac- tical argumeutum ad hominem, to the reader at least, must be the performance, by the reader himself, of the test conditions accepted in the above extract. The writer, being naturally interested in popularizing his own invention, will always be happy to supply explanation on any points which may be obscure to his readers, and will, under certain limits, give instructions to persons desirous of practising the accomplishment, whether swimmers or not. The said limits being that, as his instructions would be gratui- tous, it would obviously be unfair to professional teachers, to deprive them of paying pupils, or to continue the duties of an honorary instructor where any professional swimming master, com- petent to teach plate-swimming, undertakes the duty. Feeling convinced of the possibility of facili- tating the acquisition and practice of the art of swimming, of aiding materially human locomotion in water, and increasing both the power and speed of swimmers, by simple me- chanical means, the writer of this little treatise Introductory. 1 5 experimented for several years on the formation of practical fins and flippers. The results of his investigations were communicated to a few of those interested in the art, professionals and amateurs, in a lecture on " Swimming and Swim- mers/' delivered at the Marylebone Baths in April 1876. He then gave his system the title of " Plate-Swimming." The devices used were patented, to ensure at once the association of his name with the original invention ; and to prevent piracy of any credit due to the results attained, the assistance of the firm of Messrs Silver & Co. of Cornhill was secured as an assurance of sound manufacture, and sets of plates were presented to a few prominent members of the profession. During the first season, last summer, little or nothing was done in the way of push- ing the system with the public, no advertise- ments whatever being sent to the press. The writer gladly acknowledges having met with some educated and intelligent instructors of swimming who have shown a reasoning appre- ciation of the principles involved, as well as practical accomplishment in the art of natation, and who have taken keen interest in the utiliza- tion of artificial appliances for aiding swimmers, but this only in a few exceptional cases. It appears to be a common delusion that any winner of swimming medals or races, almost 1 6 Plate- Swimming. any one who " knows how to swim/* suffices fof the post of swimming instructor. But it is not always, or even often, that an uneducated per- former is also a good instructor of the art. As a rule, those who have been "educated " in general and cognate subjects, not merely "in- structed " in the routine of their speciality, arc willing recipients of suggestions for reform or improvement, while many self-styled "professors' 5 of the art, profoundly ignorant of all else, are very professionally conservative in their ideas, and bitterly opposed to what they deem " new- fangled notions." Some of the professionals attending the lecture in April did not hesitate to express their antipathy to the plan suggested before even hearing the address, and among some accomplished amateurs the author has observed that, while good-naturedly devoting both time and trouble to teaching the art to non-swimmers, when any rivalry was out of the question, they have evinced considerable jea- lousy at seeing themselves, despite many years of practice, easily passed in the water by plate swimmers of a few weeks' standing. " Have you seen or heard anything of Dunlop's system of plate-swimming ? " en- quired a friend lately of a professed swimming master. " No, I have not, but I know it's all humbug without seeing it," he replied. This maybe designated either "wholesome prejudice" In trodu ctory. 17 or " ignorant bigotry " according to the phase of mind exercised in characterizing it. It soon became evident that the initiation of improved methods through those wedded to more antiquated modes, was hopeless, and that it were easier to convert the instructors through a dispassionate public opinion, than attempt to introduce a novel system through those hold- ing professional and unreasoning prejudices against it. Perseverance in the plan was promoted by the fact that the only teachers of the art who had taken the trouble to practise with swim- ming plates gave the system their cordial sup- port, while the Press, on the one opportunity it had of pronouncing an opinion, accorded every encouragement. The Times, Daily News, Stand- ard, Land and Water, and other papers, in notic- ing the lecture of April last, not only fully recog- nized the advantages secured, at the stage then attained, but also the promise of the invention as appreciable from its prospects of further development. The Standard report on the sub- ject is reprinted on another page. It is thought advisable to detail the system throughout, i.e. beginning with the non-swimmer; but the descriptions will be limited, as far as pos- sible, to swimming taught with and through the use of plates. Unaided swimming action has been clearly and concisely set forth in an admir- c 1 8 Plate-Swimming. able treatise styled "Swimming and Diving," by Mr. William Wilson, of Glasgow, a work all amateurs ought to read. In short, the primary object of this book is to teach " Plate-Swimming," but for that purpose it is necessary to state in a popular and prac- tical form, a few of the scientific principles of all swimming, accepting the dictum of one of our greatest modern teachers, that " science is no- thing more than organized common sense." Report of Mr. Dunlop's lecture on " Swimming and Swimmers," from the Standard of April 2ist, 1876, alluded to in the foregoing preface. "ARTIFICIAL AIDS TO SWIMMING. " An excellent exposition on swimming was delivered last evening at the Marylebone Swimming Club by R. Wallace-Dunlop, Esq., C.B., the inventor of some nove and very effective aids to swimming, which address, delivered to a considerable although select audience, was admirably illustrated by lime light views on the screen and diagrams, and finally also by some most expert swim- mers of the above and other clubs in the great swimming bath itself. " The rinkomania,and Captain Webb's celebrated swim, had clearly given the lecturer the idea that swimming ought to become as fashionable a recreation as roller- skating ; whilst as an additional basis he brought in very substantial reasons why soldiers, and sailors in particular, and the public generally, should be educated in this use- ful and healthful art. His immediate object was, of course, to bring into notice his own invention for aiding Introductory. 19 human natation by ' plates ' and ' flippers/ easily attached to and detached from the hands and feet, but his reference to the system introduced by General Pfuel in Germany, of soldiers having to learn swimming as a part of their drill, was a strong practical point, especially as the French and other Continental armies have some equivalent in - struction, and no good reason can be stated why it should be neglected in our army, still less in our navy, the only useful efforts at present making in this direction being due to philanthropists like Lord Shaftesbury, or Mr. John Macgregor of the London School Board better known as ' Rob Roy the Canoeist,' who in training ships like the Chichester^ transmute the little waifs and strays of our cities into hardy sailors for our navy and mercantile marine. The contrast between swimmers and non- swimmers was vividly brought out also by two recent con- spicuous cases namely, the loss of life which occurred last year amongst a party of soldiers upset only a few yards from the shore of the Medway, and the burning of the Goliath, in which instance, out of the hundreds of little fellows, scarcely more able, one might suppose, to take care of themselves than old soldiers, comparatively few lives were lost, as numbers of them swam to shore when they found their ship disappearing, the captain's daughters diving off the burning deck and swimming like the rest. A third class of accidents, amongst others, in which swimming was of high importance, was referred to namely in iron ships, with which the average time between collision and sinking is seven to eight minutes. In relation to the public there is an absolute consensus of opinion, medical and general, as to the benefits of bath- ing and swimming, and yet as a rule the public do neither. The commissioners of public baths for Marylebone, Mr. Dunlop pertinently remarked, who had at a cost of ,7,000 built the baths in which they were congregated, quote on their handbills a very apposite extract from the writings C 2 2O Plate-Swimming. of Dr. Abernethy, whose opinion it was that 'next to eating and sleeping the swimming bath ranks amongst the very foremost of the necessaries and supports of life.' And yet there are, he added, only about twenty large swimming baths in London for nearly four millions of people, and these are never full even in summer, and are most of them closed in winter. One object of his present effort towards popularizing swimming would be to fill these baths, and he thought the best chance of accom- plishing this was by making swimming easier and more agreeable, and practised in dress by both sexes, much as dancing, riding, skating, or croquet are practised now. In the old heroic days of classical history, when Leander swam the Hellespont, he used, so far as can be gathered from tradition or record, the ordinary breast stroke ; and when a far greater swimmer crossed the British Channel last year, he too, throughout his long labour, remained not only naked and unbuoyed, but with his limbs as un- furnished for locomotion in water as were those of his renowned prototype three thousand years before. After thus pleading with much eloquence for the advent of a fashionable era in swimming, Mr. Dunlop gave a series of really lucid and scientific explanations of the natatory appliances and swimming actions of seals, fish, beavers, turtles, and other notable professors of the art, pointing out in each the special mechanical principles involved. "After this the immediate subject of the discourse was taken up. The first lesson Mr. Dunlop says he learnt in his search for a practical fin or propeller for human beings was that, owing to the impossibility of introducing nerves and muscles for economic expansion and contraction of such devices, all jointed, hinged, and umbrella fins are practically worthless. If the opening and closing of the fin is made dependent on the action of the water during the stroke of the arm or leg the greater part of such stroke is non-effective, being employed in the expansion Introductory. 2 1 of the fin ; and the effective complement of the stroke after expansion does not compensate for the extra friction and drag of the apparatus during closing and recovery. It must be remembered that the length of the leg stroke is from 2ft. to 2ft. 6in. only, and that the action is not directly backwards and forwards like the connecting rod of a crank or the piston of a steam engine, but that the feet trace a cycloid. His plates and flippers, therefore, Mr. Dunlop makes stiff or only slightly elastic the term ' plate ' being applied to those artificial propellers in which the hand or foot attachment is over the centre of its pressure area ; and ' flippers ' to those in which it is eccen- tric, considerable elasticity of action being afforded in the latter case, but less power and variation in the use of the instrument. The plates are, however, the more gene- rally useful, as they do not prevent walking on rocks or on the deck of a vessel, and are equally effective for back, breast, or side stroke. " The practical illustrations with which the evening terminated were excellent, and did credit to Mr. Dunlop's acumen and judgment. The experts were Ainsworth, captain of the Serpentine Club ; MacGarrick, of the Marylebone ; and J. J. Rope, of the Otter Club, the former (MacGarrick) swimming the full length of the bath atop of the water with a 42lb. iron weight slung round his neck, and then, with 42lb. displacement in the shape of two life-belts, at the bottom of the tank under water. An attendant at the baths, dressed as a soldier in heavy marching order, with knapsack weighted to 6olb., his full number of rounds of ammunition placed on his shacko, his rifle slung over his shoulder, managed to get from end to end of the tank, and landed safely ; and Mr. Dunlop's son a slender, well-formed boy made very good tracks indeed in the water. These two, repre- senting untrained ordinary swimmers, were testimony of the assistance the plates would be likely to render in the 2 2 Plate- Swim m ing. case of soldiers fording rivers and in shipwrecks, by enabling unskilled persons to keep themselves longer afloat, and to gain greater distances than would other- wise be possible for them to do. Mr. Dunlop's chief claim is that his plates will make a powerful swimmer of a weak one. " A hearty vote of thanks was given by the audience to the lecturer on the proposal of Captain Cockburn." CHAPTER II. NON-SWIMMERS. ONE point on which all rational teachers of swimming are agreed, is the desirability of allowing the tyro to gain confidence gradually. He should, in the early stages, be restrained from, rather than urged to, experiments risking anything like swallowing or inhaling water. Nothing more idiotic can well be conceived than the "good old custom," once prevalent at public schools, of throwing in the smaller boys ; indeed, all trickery, practical joking, or ducking of the inexperienced, should be sternly stamped out. It is not necessary or desirable that a begin- ner should plunge in, let him be content to wet his head and walk into the water. The first instruction should be to impress on his mind that by inhaling a long breath of air prior to dipping the head, remaining a few seconds under water, and exhaling on emerging therefrom, no inconvenience is experienced ; this fact once learned, he will know that the 24 Plate- Swimming. gasping, choking, and annoyance, resulting from inhaling under water, is due, if it occurs afterwards, to his own awkwardness or misman- agement. The writer once saw a teacher of swimming introduce his son, a fine plucky little fellow of six or seven years old, to the water in a tepid swimming bath. The boy was quite fearless and anxious to learn. His father entered the water, then took him on his back, making him hold on by his neck, and swam round the bath. He soon called out " Now then, Tommy ! shut your mouth!" and dived under water. Poor Tommy may have shut his mouth but could not also shut his nostrils like a seal, nor could he be expected to refrain from inhaling when under. He naturally came up a miserable look- ing object, choking and coughing, while his father putting him out on the side, tenderly wiped away the phlegm and saliva oozing from nose and mouth, and encouraged him by words, after having seriously injured his morale, and thrown him back several weeks by his first lesson. The most favourable position in which to acquire swimming action is when the learner is aided by displacement in water, i.e., wearing a macintosh belt or cork floats. The dread vul- garly entertained of some danger from change of position of the belt, or of its getting entangled Non-Swimmers. 25 with the feet, is unreasonable, no change is pos- sible if the appliance be properly attached ; but macintosh is always liable to leaking from punc- ture or rotting of the material ; it appears to lose all its good qualities, its elasticity and toughness, as soon as it loses its characteristic evil odour. The cheapest and safest life-preserver possible is made by collecting a number of bottle corks and sewing them as close together as they will go, on to an old waistcoat. This expedient was first mentioned to me by Mr. Humphrey, a teacher of swimming. A pair of cork hand- plates strapped to back and chest, also form an excellent life-buoy. As soon as a lad has attained a sound and slow action with the floats on, and this in most cases is attainable in three lessons, he need only continue the same stroke with the floats off to swim unaided. This I have tested in repeated instances ; the period of nervously hurried and exhausting effort common to most beginners, may be shortened, if not avoided by first teach- ing them, when comfortably buoyed, the regular system of correct movement. In the ordinary breast action, almost all the propulsion should be done with the legs, the arms being chiefly occupied in supporting the weight of the head. It is therefore of great importance to acquire from the first a powerful 26 Plate- Swimming. leg stroke. For this purpose it is usual to recommend the beginner to hold on to a bar at the side of the bath, or hang from a rope or loop attached to the ceiling, or be held by the teacher, and then kick out with the legs. In lieu of such aids the plate-swimmer gives the learner a pair of cork hand-plates, nine by ten and one and a half inches thick, or with nearly 100 square inches of horizontal face, or pressure area (vide wood cut at page 58). The outline is of little importance as speed is then not an object. The mode of attachment is, as with all hand-plates, a single buckle and strap passing through two slots in the plate and forming a loop through which the four fingers of the hand pass. The displacement of such a pair of plates is equivalent to seven pounds of dead weight, and it is evident that by such assistance not only can the leg action be easily 'taught, the support moving on as required by the learner's progression, but the synchronous action of the hands can be acquired in connection with it. To show how the buoyancy, independent of mechanical float power in such plates, may be calculated, if the reader will utilize the table of specific gravities which is borrowed at page 6 1 from Baker's Dynamics, he will find that such a pair of plates give him, allowing a small correction for bevils and rounding of the edges, some 288 cubic inches of displacement, or N on- Swimmers. 27 about nine pounds six ounces of water ; and as the cork causing said displacement itself weighs only two pounds eight ounces, it affords a buoyancy of six pounds fourteen ounces of dead weight. If he test the same empirically with well varnished cork, by floating and plac- ing weight on it until the water just covers the whole of the cork, he will find the result even more favourable for buoyancy, the cork being dry and its air cells protected by the varnish, it will carry over seven pounds of dead weight, by which is meant weight above, not floated in the water. The best possible preparation, by dry land drill, for practice in water, is to support the learner by a stool under the abdomen, while his wrists and ankles are placed in leather loops suspended by cords from ring bolts in the ceil- ing, by this means all injurious strain can be avoided, and the combined action of arms and legs so far mastered, as to ensure every pupil of good nerve, swimming across a bath during the first lesson. It appears to the writer to be of more im- portance to state the principles on which swim- ming progression depends, than to lay down dogmas as to the details of action. Much de- pends on physical conformation, and an intelli- gent learner will soon test the styles best suited to his own individual make or figure. 28 Plate- Sivimming. If, for instance, we glance at the instructions as to leg action given in some of the latest publications on swimming, we find in a small " Handbook of Swimming " by Messrs. Rout- ledge, p. 23 : " The legs, which should be moved alternately with the hands, must be drawn up with the knees inwards, and the soles of the feet inclined outwards ; and they should then be thrown backwards, as widely apart from each other as possible." In a book by Sergeant Leahy, a swimming teacher at Eton, " The Art of Swimming in the Eton style," we find, p. 5, these words : "With the soles of our feet we balance our- selves and walk on the land ; and with them also we propel ourselves through the water. To use the soles of the feet to the greatest advantage, that is to strike the water with the soles only, the knees, as I have said, ought to be turned out, and the toes drawn up towards the shins before every kick." Again in Captain Webb's book, p. 31 : " Here let me observe that it is a popular fallacy to imagine that the speed of the swim- mer in any way depends on the resistance of the water against the soles of the feet. I have often heard it observed": ' Oh, that man would make a fine swimmer ; he has got such large feet. ' Now, in the movement of the legs Non* Swimmers. 29 the flat of the foot never directly meets the water, except in the case which I shall here- after mention, known as 'treading water.' The propelling power in swimming is caused by the legs being suddenly brought from a position in which they are placed wide apart, into one in which they are close together like the blades of a pair of scissors. In fact the mechanical power here brought into play is that of the wedge. For instance, suppose a wedge of ice were suddenly pinched hard between the thumb and finger, it is evident that the wedge of ice would shoot off in the direction opposite to that in which the sharp edge points." These last two teachers are like the knights with the gold and silver shield, each looking at one side only, and each in a sense right as to the point on which he insists. As a matter of course, as large a cone or wedge of water as possible should be grasped by the legs ; and it stands to reason that if this wedge of water from which the forward impulse is obtained, were a wedge of ice, it would be of little consequence what the pressure area or diameter of each leg might be ; but it is very different with a yielding and fluid matter, a pair of scissors for instance as long as the legs, would obtain but little spring off a cone of water. It stands to reason, also, that the value of 30 Plate-Swimming. each unit of this pressure area of the legs is in direct proportion to its distance from the hips. In fact, that the most important and widest traverse is obtained by the feet ; and it is very desirable to increase the pressure area at the most important point, by using the sole, not the side of the foot, in bearing on the water- wedge described ; this, also, adds the impulse due to the fin-like action of the ankle-joint in that position. The same principles regulate the use of the flat, or palm of the hand, which should be passed edgeways through the water during " recovery " to ensure the minimum of resistance to its transit, while during the " stroke " it should be turned square to the direction of its motion, to obtain the maximum of resistance to its passage, i.e., grip of water. The principle of " plate-swimming" is the increase of the pressure area, by which pro- pulsion and surplus float-power are secured ; it is simply assimilating the hands and feet of human beings to those of certain aquatic animals, such as the sea-lion and turtle. When the non-swimmer, placing his hands in the loops of a pair of cork-plates like those illustrated, lays his length in the water, his head is sufficiently raised without effort or movement, and he is able by even a crude imitation of the correct action to travel round a bath at the first essay. So soon as his action is Non - Swim mers. 3 1 tolerably correct, the foot plates (page 34) may be attached, the next step is to exchange the cork hand plates for wooden ones, and a begin- ner usually succeeds in plate-swimming, travers- ing the length of the bath or round it in one lesson. For the second lesson, after practising with the plates on, and alternately with those on the hands or feet alone, after the learner has been warned to continue a slow steady stroke, the plates may be taken off, and he will find that he can cross the bath unassisted. Under any circumstances, and with the most nervous bathers, a few days' practice at most, ensures facility of swimming both with and without plates. The irregular jerky action often adopted by self-taught performers, is impossible while using the plates, because all action not perfectly true causes " drag," which modifies and corrects irregular movements and in fact insures, not only perfect action while " plate-swimming," but the habit of correct action, which remains when swimming unaided. The writer has frequently been asked why he did not devise a fin to open and close in lieu of plates ; an abstract of the objections to collaps- ing appliances has been quoted at the end of last chapter, in the extract from the Standard report of lecture ; but it may be added that a 32 Plate- Swimming. great variety of such devices have been tested, and the popular tendency to such delusive aids is proved by the fact that three-and-twenty patents or provisional specifications of such hinged and jointed contrivances have been entered at the patent office, all collapsing, in more senses than one. The great impediment to the utilization of swimming-plates has been the human heel. No swimming animal, we may say no animal but man, has a heel, and the ninety degrees of play now obtained for the foot-plates has only been secured by letting the heel through a gap, and taking a bearing principally from the ball of the foot, so utilizing the play of both the ankle and the metatarsal, or instep, joints, to bring the plate in line with the leg or square to it at will. 35 CHAPTER III. SWIMMERS. IT is essential, in order to appreciate the varied phenomena appertaining to swimming questions, that we keep in mind a well known law of hydro- dynamics, that, "the resistance which a fluid opposes to a body moving in it, increases as the square of the velocity." So that a resistance of, say, twenty-five units, offered to a speed of one yard a second, augments to 100 units for two yards, 225 for three, and so on. The resist- ance is in direct ratio with the area of the moving body but modified by a co-efficient dependent on its shape. As a necessary consequence of the aforesaid law, the power exerted in overcoming such resistance must increase as the cube of the velocity, for, supposing the power exerted to achieve one yard per second to be twenty-five units, the first yard accomplished at the rate of two per second takes 100 units in lieu of twenty-five to complete, and the second yard adds another 100 to bring it into the same D 2 36 Plate-Swimming. time, the total 200 representing eight times, or the cubical proportion of, twenty-five. At page 371 of Molesworth's " Pocket Book of Engineering Formulae," published by Spon & Co., Charing Cross, the reader will find the rules for proportioning power and speed algebraically expressed for screw steamers. As instanced by an engineering friend of mine on one occasion, an ironclad of 3000 H.P. running at half power made ten knots an hour, while full power added but a little over two knots to her speed. It is evident that a point must soon be reached when, practically speaking, any increase of power will hardly add to speed. With our present appliances twenty miles an hour may be quoted as about the limit of speed for steamers, and roughly speaking one and a half yards per second is the ne plus ultra for swimmers. This affords some explanation how it is that while all good swimmers can go a yard per second, the most strenuous exertions are requi- site to accomplish fractional increments in excess of it, and an immense amount of extra energy has to be used by athletes like Jones and John- son when making time that shows in distance but a few inches per second over that of ordin- ary good swimmers. It is well known that in racing, as a rule, competitors sink as much as possible of their Swimmers. 37 body, in order that their efforts may not be wasted in floating or supporting it, but entirely utilized for propulsion. It is evident if we bring the before quoted rule to bear on the question, that the growing volume of resistance, owing to the density of water as compared with air, quickly brings a point where it is more economical to raise the body partly out of water, than to devote the entire power available to propulsion direct. Practically this is demon- strated by the action of the hundred yard champion, Mr. Trudgeon, who, striking down- wards as well as backwards with his hands, raises his body considerably out of the water, and accomplishes great speed, but at a cost of exertion which precludes its continuance for more than a short distance. Similarly, in the case of what are known as the wave-line build of vessels and boats, designed by Messrs. Scott Russell, Coryton, Ramus, and others, when running beyond a certain velocity they partly rise from the water, their draft diminishing in proportion to their rate of speed. It is not unusual to see self-taught swimmers who merely draw the legs and feet up for recovery and jerk them back for stroke ; they care nought for wedges of water or width of traverse with the feet, yet some of them are comparatively fast swimmers. Their propulsion 3 8 Plate- Swimm ing. is gained by utilizing the law of hydro-dynamics before expressed, i.e. if they only strike back the feet at twice the speed they draw them up, they gain for the forward impetus nearly twice the rearward drag. It must not be forgotten that plate-swimming is an accomplishment as distinct as roller- skating, and although many persons, find no difficulty in using plates at the first trial, their slide and grip of water, if misused or inverted in action, will impede or obstruct a novice just as they give power and speed to an expert. The writer has seen a person, proud of his proficiency in swimming, put on the plates for the first time, blunder about awkwardly on the surface and then disappear under water. On coming up spluttering to his feet, he promptly pulled off the plates and refused to try them again, complacently ignoring any awkwardness on his own part, he denounced "swimming- plates " as being being " very bad things " they drag you imder. This could only be paralleled by a tyro pulling off his skates at the first tumble, and pompously announcing that they throw you down. The swimmer who tries plates for the first time had better be content to use those for the feet only, wearing the anklet attachment, and making himself familiar with the character of the foot action before trying them on the hands Swimmers. 39 also. Although hand-plates are very useful in broken water, and essential in weight-carrying, all travelling should be thrown on the legs. In the illustration at the commencement of this chapter we have the pattern of hand and foot plates best adapted for general purposes. It will be seen that the hand-plate, which measures about eleven inches by eight, and is only three-eighths of an inch in its thickest part, has the simplest possible form of attachment a strap passing through two slots about four inches apart and so forming a loop for the hand. It will be seen that the foot is attached to the plate by a laced upper of leather. There are brass staples with sliding rings on each side of the heel gap, and there are two methods used for securing to the ankle : Firstly. By an anklet, instep strap, and heel strap, vide p. 34. Secondly. By a single long strap combining the three pieces in one, vide p. 46. This last is used by those who will not be troubled to fasten more than one buckle ; but the first is the more efficient mode, as it allows greater freedom and play to the foot, the heel strap being carried round the achillis tendon on a metal hook does not get friction bound by it, but allows the heel to traverse easily right and left while it runs through the hook. The heel strap is preferable to a lace as being stronger, 4-9 Plate Swimming. and a buckle is a safer fastening than a knot, often carelessly or awkwardly tied. With reference to tieing laces whether for uppers and anklets or for boot strings, and parcel fastenings, a few minutes' study of the annexed diagram will, unless the reader is already initiated, afford him benefit for the rest of his life. Here are two kinds of knot shown, with appar- ently very little difference between them, but that little constitutes the difference between a perfectly reliable knot which will not draw, but is easily opened at will, and a worthless tangle which frequently draws, but which, when once tight, it is a trying penance to have to untie. The first is the " reefer's " knot, the second the "granny's," the former so called because used by all sailors when reefing, and however jammed by strain or wet, it can be unloosened quickly, with the point of a splicing pin or almost any pointed piece of wood. It takes no longer, and is not more difficult to make, than the "granny's," yet strange to say, many men and nearly all women and children know and use the latter only. The main point in plate-swimming, whatever the action used, is to ensure the plates travers ing the water edgeways during recovery and square during stroke. REEFER'S KNOT GRANNYS KNOT Swimmers. 43 The hand-plates may, of course, travel edge- ways whether the plate be horizontal or vertical in the water, and it must be understood that both with the " side " and " overhand " action it is desirable that the underhand plate be ver- tical during " recovery ; " if kept horizontal, a slight error of incline might alter the position or " swim " of the body and transfer some of its weight to the plate, so as to retard progress, while the same amount of error with a plate vertical, would only cause a trifling change of direction. The recovery of the feet may be practised either separating the knees with the inner edge of the plate leading, or with the knees together and the heels leading. A bandy legged swimmer would use the former, and a knock-kneed one the latter. As a rule both should be practised, the first being preferable for all breast action, the last for swimming on the back. At page 36 of his book, Mr. Wilson describes the improved leg stroke for the side action. He says, "With the legs, bring both feet up to the body, heels touching, toes pointing outward ; send the topmost or left foot straight in front of and as nearly as possible at right angles to the body, at the same time kicking the under- most or right foot in the direction of one's own 44 Plate- Swimming. back. This motion of the legs seems like a long stride, as in running ; now bring the legs sharply together, the top or instep of the right foot, and the inner ankle of the left foot, offer- ing the resisting surface." There is no doubt this is the action used by our best swimmers, but there are many who do not adopt it. Indeed Captain Webb, among other injunctions to the side swimmer, (vide page 43 of " The Art of Swimming,") distinctly tells him "to keep the same stroke with his legs as in the breast stroke," and this is exactly what he must do when using the ordinary or oval pattern of swimming-plates, as they are designed for taking the pressure against the water on the sole or under surface of the plate. At p. 58 a " fishtail " flipper is shown, with which the improved leg action of the side stroke can be used, and the true fishtail action imitated, as more fully detailed in Chapter VII. 47 CHAPTER IV. EXPERTS. MOST persons will know what is meant by the term "slip " of ships' propellers ; it is here used in the same sense as applied to plates, and lest some readers may not have met with the ex- pression in its technical meaning, the exact purport had better be explained. If the helix or spiral thread of a screw has such a pitch that in one turn round the shank of the screw it advances say one inch, the screw would if turned into wood or any solid material, advance one inch with each complete turn, but if the helices or blades of the screw propeller of a ship have a pitch of, say, one turn in three feet, they do not, owing to their turning in a yielding or fluid substance, advance the ship at the rate of their pitch, but lose at a rate, large if there is much static inertia, or small if there is much acquired momentum, in the ship. The difference between the distance actually advanced and that which the rate of pitch would give, is the " slip " of the screw. If when a swimmer reaches out his arm before him he could lay hold of a fixed handle in the water ; or if when he has " recovered " 48 Plate-Swimming. his feet he could find a bar behind them, there would be good purchase for his stroke and no " slip." But, owing to his legs and arms being better proportioned for work on land than for grasp of water, the slip, in unaided swimming, amounts to about two thirds of the stroke. Much of this slip is of course saved by using plates, it is reduced not eliminated, and as the slip is caused by the power applied, or pressure exerted by the swimmer, they necessarily bear a ratio to each other. In the following diagrams therefore both swimming and sculling action are illustrated, by indicating the "slip" and relative pressure at each point of the movement. On the annexed diagram, the feet action only is shown, but that for sculling represents accu- rately also the movements of the hands, if it be supposed that the curves are separated by the width of the body. For swimming foot action the movement is the same whether en breast or back. We will suppose the feet to be recovered at A, the heels and outer edges of the plates then lead off to B and D respectively ; but slight pressure, commencing until the direct paddle blow BC and DE initiates the movement changing to the incline pressure along CF and EF. The strokes lengthening and the slip diminishing as the body gains momentum. The sculling movement is performed on the back, and is useless without the plates, sup- Experts. 5 1 posing the body to lie fully extended and the feet at a the knees are turned in, then the legs separated from the hips, to b and c. Though it is difficult at first, in this portion of the movement to make the soles of the plates bear strongly on the water, it is quite easy to run them edgeways through it, and so " recover " for the second portion of the stroke, in which, the knees being turned outwards, the plates get a good inclined bearing on the water, and being brought sharply together, propel the body effectually. The same sculling action being carried on by the hands, considerable speed without great effort, and without splashing, is attained, one great advantage being that the face is throughout above water, and breathing easy even when accelerated by exertion. The small amount of unprofitable action, in the necessary turnings, is shown by the dotted lines. The most conspicuous proof of the great power given to swimmers by swimming-plates is shown in weight-carrying, and the varied methods of utilizing this power are of primary importance in saving life. Swimmers who can- not,. in unaided swimming, carry for the length of the bath twenty-five pounds of immersed ring weights, can carry double that amount when using plates, while by merely treading water the plate-swimmer raises his head, thorax and shoulders, above the surface. In other words, E 2 5 2 Plate-Swimming. he has for the assistance of a drowning man, some twenty pounds of surplus power available. A plate-swimmer approaching any one in difficulty would seize his arms between the shoulder and elbow, from behind if possible, and by holding his head above water reassure and encourage him. If he is persuaded to hang by the arms round the swimmer's neck, his weight w r ill be favourably placed for carrying, as illustrated in the sketch from life, of weight- carrying, vide frontispiece. The heads of the swimmer and the person he carries are then side by side. It is easy to understand how different is such a position from the ordinary one in which the drowning man and his rescuer are sometimes under water, sometimes struggling on the surface, the extreme limit of the latter's strength being unequal for more than a few minutes of time or a few yards of distance. Most swim- mers entertain very delusive ideas as to their powers in this respect ; in a canal or river it is of little consequence how the victim is pulled to bank, a few feet only may be accomplished in some fashion, though lives are often lost even under these apparently easy conditions. It is as well to mention, that where there is occasion to drop the hand-plates and resume them again, it is advisable to attach them by a lace, run through the outer edge near the wrist- gap, and tied to the arm just above the elbow, Experts, 53 In most accidents while at sea, with a ship under way, all ordinary unaided swimming is impotent to save a drowning man. A melan- choly case has recently been reported by tele- graph, which strikingly illustrates this fact. On the 1 3th December last one of Her Majesty's ships, the Newcastle, was on its way home from China, when a sailor fell off the yard- arm into the sea; a gallant young midship- man named Wingfield, an excellent swimmer, sprang over the side to rescue him, and two seamen, both good swimmers, followed shortly after; the ship was brought to, and boats lowered at once, but bearings are very difficult to keep when the ship swings half round the compass, and a weary waste of waters must intervene ere the smartest crew can stop her way, whether under sail or steam. Wingfield was last seen, having reached the man he sprang to save, struggling to keep his head above water, but none of the four zvere ever seen afterwards. A man of the splendid physique of Captain Webb might perhaps save a life in such a case, and it would have been easy with the precau- tions taken, and a row-boat close at hand, for Baker to have rescued him had he succumbed, during his marvellous feat of endurance in cross- ing the Channel, just as Pamplin saved Cavill when persevering until unconscious to rival that achievement. But a rescue in a broken sea, when a " few minutes " and " a few yards " are not 5 4 Pla tc- Swimming. factors in the formula, offers a problem insoluble to unaided swimming. All honour to those who at the cry of " a man overboard " spring into the water after him as a matter of course; but let the fact be noted for prompt action in such emergen- cies by all in a position to aid, that where the savingof a non-swimmer is concerned, the instant cutting loose of a life-buoy and the lowering of a boat are so far essential, that a question of a few seconds sooner or later is a question of life or death. A study of the details of acts for which the Humane Society's medals have been given since 1830, published by Lambton Young, Esq., the Secretary, will enable the readers to judge what is possible and what impossible to human effort by unaided swimming. We now come to a point more important in this connection than even weight-carrying. Any- one who has seen J. MacGarrick of the Maryle- bone Baths, when plate-swimming with an in- flated lifebelt round his waist and a nautilus collar round his neck, go down at one end of the long bath and after swimming along the bottom come up at the other end 73 feet distant, will understand how important the use of such diving power, in overcoming and utilizing dis- placement buoyancy, might prove to be. A swimmer so provided, carrying down a lifebelt to a non-swimmer who had already sunk, could find no difficulty in raising him, and would have Experts. 5 5 no dread of the hug of a drowning man, as the belt alone could keep their heads above water. Another very important benefit from the com- bination of great grasp of water and displace- ment buoyancy, especially if the latter be applied as directed in Chapter VI., will be found in swim- ming through surf. Captain Webb very justly says, "To attempt swimming in a heavy surf would be an act of folly for any one, however great a swimmer he might be, unless he were possessed of considerable personal strength." Now it is just some equivalent for this excep- tional power that I design for ordinary swim- mers. Most persons are pleasingly surprised at their first experience of the ease with \vhich they can surmount great rollers in a heavy sea, when once they have got away from the shore ; but there are two difficulties, or rather dangers, to be avoided when crossing surf, the one being struck down by the curl of a wave, and the other being dragged back when trying to land, by the reced- ing water. However artificially aided, the swimmer can- not do better than follow the instructions of the greatest authority we have on this speciality. Captain Webb says, page 66, "The great art in returning to shore is, not to attempt to battle with the waves, but to manoeuvre with them so that they assist you. Should a huge mass of water be bearing down upon you from behind, 5 6 PI a te- Swim m ing. wait till it nearly reaches you, and then suddenly dive downwards, swim a little way under water, as far as you can, against the waves. By this means you will avoid being caught in the crest of the wave. Then turn again and strike out to shore, and let yourself be carried on the huge bend of the wave, which will take you rapidly in. The waves by this means will bring you nearer and nearer the shore; and the nearer you get the greater must your care be that you don't get caught, as I have said, in the crest of the wave, the effect of which will be to dash you on the beach, and probably, at the same time, knock all the breath out of your body. It will generally be found that every third and every ninth wave is larger than the others, and, also that every large wave is followed by a much smaller one. In reaching the shore, therefore, watch your opportunity, if possible to land as soon as you can after these great waves have broken. " In swimming out through the surf you must of course, start in one of these small waves, and when the sea appears to be in its calmest moments. Again, the first time you see a heavy billow higher than the rest rolling with tremendous force towards you, wait till it is nearly on you, then dive quickly and swim with all your might against the water as long as you possibly can, and your head will shoot above water when the wave itself has passed far back behind you.'* FISH TAIL FOOT FLIPPER 59 CHAPTER V. FLOATING AND DIVING, THE crudity of current views on swimming questions is shown by the practice still prevalent of quoting Dr. Franklin's essay, including the quaint superstitions it contains, as if the latter were scientific facts. In the edition of a popu- lar work of reference published so late as 1873, we find full paraded, his injunctions as to opening the eyes before diving, because of the difficulty of doing so under water owing to the pressure of the fluid on the lids. The English Encyclopaedia ignores the art of swimming, the Encyclopaedia Britannica quotes Dr. Franklin. We often hear the mischievous fallacy repeated that the specific gravity of the body being less than that of water, if non-swimmers only had the presence of mind to lie quietly extended, keeping the head well back, they would float even if the legs sank " till they were almost in a standing position.'' Most of our bathing accidents take place in fresh water, lakes, rivers, or ponds, in which, except in the 6o case of very fat people, the body is heavier than water. The writer has himself practised, and has often seen others, diving to the bottom of a swimming bath, and lying there motionless for a few seconds. When this is possible it were just as true to call two and two five, as to say that the body, bulk for bulk, is less in weight than water. In fact motionless floating is a feat for ex- perts and one requiring considerable practice. It is accomplished by retaining throughout respiration, a certain amount of air in the lungs ; without practising this constrained mode of breathing, any non-swimmer trusting to presence of mind, and the afore-mentioned pedantic delusion, would infallibly be drowned. As a general rule it may be accepted, that the body is lighter than water when the lungs are filled with air, but when they are emptied by exhalation, it is heavier than water. As, hov/ever, the surplus in specific gravity of the body is but trifling, very little additional displacement suffices to raise the face above w r ater, and any- one wearing plates of light wood may even go to sleep while floating, because natural breathing without sinking is practicable. A friend, late in the Indian navy, assures the writer that with the added buoyancy only of a Manilla hat he has slept for some time floating in the harbour of Jeddo. Floating and Diving. 61 As a matter of course the thick plates made for beginners are much lighter in water than the thin plates designed for experts, that is to say, the displacement of the former being much greater than that of the latter, they are lighter to wear for floating or slow movements, but much heavier to move through water during rapid progression. There is great difference between the specific gravities of woods ; for instance, taking (weights in ounces per cubic foot) Fresh water at 60 degrees . . rooo Sea water is .... 1*026 Oak and mahogany, about equal, "925 Beech "850 Elm '600 Fir -570 Poplar . . .

The power of resting during protracted exertion in long distance swimming is of great importance to the swimmer himself, but as a means of aiding others in difficulty, or at any- rate of saving life when the victim to be rescued has already sunk, it is of but minor importance 62 Plate-Swimming. compared to the power of diving, with facility of movement and command of direction under water. The period of time during which human beings can stand submersion in water without losing consciousness, is a question of consider- able interest to physiologists, as well as all classes of swimmers. The power of a diver to save life, in cases where a non-swimmer has already sunk, depends often on the amount of time he can devote to search under water for the body, or to disentangling the same from weeds and raising it to the surface. Most scientific works give from one minute forty-five seconds, to two minutes as the extreme limit of human endurance in this respect ; and this coincides with the experience of officers in charge of the pearl fisheries of the Persian Gulf. The chief pearl fishery of the world, in the neighbourhood of Bahrein and the E. I. C. islands, having a pearl fleet of some 10,000 boats, manned prin- cipally by Arabs, is, or lately was, kept in order by a gunboat or British Government vessel sent to keep the peace among them. Captain Tronson of the late E. I. Company's fleet, who was for some time in command of this vessel, informed the writer that he has had hundreds of opportunities for testing by the ship's chronometer, the moment of the entrance and exit from the water of the divers Floating and Diving. 63 around his ship. He found that the maximum period of submersion so proved was two min- utes, and that divers coming up after such an effort showed every symptom of complete ex- haustion. In this connection it is very desirable that the theory of respiration be clearly apprehended, because the phenomena attending its suspension and the practice empirically approved by divers, receive interesting elucidation in the discove- ries of advanced physiologists. I can strongly recommend to the attentive perusal of all inter- ested in such points, a pamphlet by Dr. Patrick Black, published through Smith, Elder and Co., entitled " Respiration, or why do we breathe.'* I quote later on some of its convincing exposi- tion of familiar facts, slurred over or avoided by less intelligent observers. When an experienced diver such as Mr. J. B. Johnson is preparing for a long stay under water, it will be observed that he fills and empties his lungs repeatedly by short full inspiration and exhalation. By so doing he is not merely filling the capillary air cells with fresh oxygen, which is very essential, but he is also, we may say, pumping blood through the lungs ; he is emptying the right ventrical of the heart so far as possible, just before diving, instead of commencing his suspen- sion of lung circulation with it semi-engorged. The writer tested Mr. Johnson's endurance on 64 Plate-Swimming* one occasion, when he remained under water for three minutes and thirteen seconds. There is also ample evidence of his having done so for three minutes thirty-five seconds, while his brother, Mr. Peter Johnson, has been more than four minutes under water. This, however, re- presents quiescent endurance of suspended res- piration only, whereas the active effort of col- lecting the pearl oysters, necessarily increasing heart action and filling the lungs with blood, must shorten the period of submersion possible when obtaining them. Mr. Peter Johnson's longest swim under water is reported slightly to exceed one hundred yards, and this at the rate of nearly a yard per second, which is pos- sible for divers, represents not more than the two minutes maximum accomplished when active muscular effort is imposed on the pearl fishers. Dr. Black says, " In speaking of the chemistry of respiration, I seemed to show that although the blood's aeration was the ulti- mate end to be attained, yet this might in a certain sense be considered incidental to the primary end, viz., that of the expansion of the air vesicles, without which expan- sion the blood could not pass onwards. Now, there are two forces which tend to expand the lungs ; one is the expansion due to the heart's vigorous contractions, such as take place in violent exertion, when the heart is beating with almost twice its usual frequency ; this is a force acting from within, and tending to push outwards the walls of the chest. Floating and Diving. 6$ " The other force is a power acting from without, one which tends to enlarge the chamber, to fill which the lung will swell out by the air rushing in by the windpipe and its branches. In the one case the lungs are filled with blood, in the other they are only filled with air." Again " Physiologists have taken account of the number of cubic inches of air we inspire in ordinary circumstances, and also of the greatest quantity we can draw in and give out under the most forced efforts. Now it is obvious there must be a limit to the extent to which the chest will: admit of expansion. The chest at its fullest expan- sion after a forced inspiration is said to contain about 330 cubic inches of air, in its medium condition about 200. Now this gives us a proportion of about 20 and 12 ; 20 representing that degree beyond which the chest will not admit of any further expansion. If it were possible that the heart by its own energetic action could so en- large the lungs as to bring them up to this limit of 20, life would not only be imperilled, but if such a state of things were to continue for a minute, or perhaps a little longer, death would be certain. Who cannot remember instances when, either in his own person or in that of others, he has been made conscious of that intense distress, when after the utmost exertion, he has found it impossible to draw his breath ? I have heard people describe it in the words, ' I thought I should have died.' I sometimes put to young students of medicine the following question, ' A man runs a few hundred yards at the top of his speed, at the end of which he is out of breath. What is the phy- siological explanation of this condition?' I have just given it you, but I will repeat it. The lungs are filled with blood not with air, though indeed they contain pro- bably more air than at any lower point of expansion. To enable this blood to pass onwards to the left chamber of F 66 Plate- Swim m ing. the heart, expansion of the air cells is now necessary, but if the limit of expansion has already been reached, death is inevitable, because this left chamber of the heart is starved of its supply; it has nothing to contract upon. You see then what a difference it makes whether the chest is expanded by the muscular forces external to the lungs, or by the force of the circulation within them, which imperatively demands a still further effort from without. In the first case we draw in air, and blow it out again at our will; in the second we pant in our almost vain efforts to give further expansion to the lungs ; and this state continues until the circulation slackens from enforced quietude." In considering these details the idea naturally suggests itself, that if it were possible to unite in the shape of a lozenge, any salts which, with the addition of water, developed a non-irritant gas, the dilatation of the lungs and their mechanical action in circulation would be secured under water, and a few moments' time at least for effort and observation beneath the surface gained. As a matter of course absence of oxygen in the lungs would very soon produce insensibility, but for a few inspirations it is possible to do without it, as instanced where nitrous oxide gas, which has no free oxygen, is inhaled. The suggestion as to " diving lozenges " was made to an acquaintance engaged in chemical work, some time ago, with no result ; but it is still to be hoped that chemical ingenuity and research may lead to some practical utilization of this line of invention, Floating and Diving. 67 Captain Tronson of the Indian navy mentions, that on one occasion a slipped anchor which was visible through the clear waters of the Red Sea at a depth of sixty feet, was recovered by an Arab diver, who succeeded in reaching it and hooking a chain to its ring, but he lost conscious- ness before he got to the surface again, and was rescued in one of the ship's boats when insen- sible and bleeding at the eyes, mouth, and ears. It was, doubtless, the muscular effort required to complete his task, which proved the prover- bial feather in this case. On another occasion, when the cable had twisted round coral in the harbour of Jeddo, the depth varying from 12 to 15 fathoms, an Arab went down repeatedly, and standing at the bottom, freed it without ill effects to himself. Mr. Wilson describes a diving competition in which he was himself engaged, in the Frith of Clyde off Greenock, where one of the competi- tors, Mr. James Milne of Edinburgh, brought an object from the bottom, at a depth of seventy- two feet. The Somalees,aswell as the Arabs about Aden, are admirable divers ; if a rupee be thrown into the water from the deck of a ship, one or more of the lads swimming around will pursue and secure it before it has sunk more than a few feet When approached by two divers about the same moment, they fight under water for its possession. F 2 68 Plate- Swimming, When dashing into the water from the deck of a vessel after a shoal of fish, they frequently succeed in seizing one. A friend of the writer once saw a diver bring up one in each hand; caught of course, not by any speed of swimming, but much as an omnibus catches, and unless pulled up, would run over an old female at a crossing, fear and confusion of mind producing paralysis of action. Natives in India, many of them mere children, practise diving from great heights, always feet foremost, into large wells or tanks, in the hope of receiving some trifling pecuniary reward from spectators. At the Bawalee or Great Well near the Kootub pillar of old Delhi, the writer has been boys springing off every stage from top to bottom ; and at the Khund or water-hole among the towering ruins of Futtehpore Sicri, near Agra, he has seen native boys climb to the third and fourth stories, then spring from a window, struggling during the descent to keep their posi- tion, feet downwards, just as they approach the water suddenly straightening the body, seizing the nostrils with the finger and thumb of the right hand, the arm close to the chest, the left arm close along the side, or sometimes held above the head, they then appear to enter the water with the rush of a cannon-ball. For practical purposes however, the feat of diving from heights exceeding the deck of a Floating and Diving. 69 ship, the side of a pier, or a river bank, may be deemed useless. In diving with plates from surface when swimming, all that is requisite is to point the hands downwards, the swimmer's momentum carries him after them without further effort than continuing the foot action. Any depth or any direction can be regulated by the same means. When diving from a bank, boat, stage, or similar height, the foot-plates follow naturally the course of the diver without further attention than pointing the toes. But if hand-plates also are used, practice and perfect command of the plates are requisite to utilize them. They must strike the water at the angle intended for the entrance of the body, as any awkwardness in holding would deflect the arms from the direc- tion aimed at, while very shallow water suffices for the plunge of an accomplished plate swim- mer. THE "AQUATIC DRESS," 73 CHAPTER VI. AQUATIC CLOTHING. IF we consider briefly the principles on which clothing warms the body on land, we perceive that, as the contact, of very cold air carries off caloric faster than it is naturally replaced by vital combustion, we seek to keep the film of air heated by contact with the body from being too rapidly changed for that of a low temperature, by interposing plies of clothing proportioned to the warmth required. Chilling may be caused either by transfusion or conduction, and warmth requires thickness of covering for the latter, as well as closeness of texture for the former. Clothing should of course be more or less ventilating to carry off the insensible perspira- tion, and renew gradually the air next the skin, and water being a much better conductor than air, it is proportionately more difficult to protect the body from cold in it. The insensible perspiration amounts to some pounds weights per diem, and the pores of the skin become poisoned by hermetical sealing. I 74 Plate-Swimming. have heard of an instance of death resulting to a little child carried in procession during one of the native festivals in India, from its having been covered with gold leaf to represent an image, and a similar case is reported to have occurred in Italy. It becomes therefore desir- able, if impervious tissue be used for aquatic dress, to allow transfusion of a certain amount of water for the renewal of that in contact with the skin, or, as it would be expressed with air, for ventilation. I have attempted with some success to meet these difficulties by the sea-suit depicted at the head of this chapter. It consists of a pair of drawers and a jacket made of the elastic woollen webbing used for " tights " by athletes ; the jacket buttons across the chest and is cut to a point before and behind so as to fasten between the legs. These garments are covered with a thin skin of rubber, and fit closely round the wrists and ankles. The suit alone allows of an hour's practice in the sea, when it is too cold for bathing with comfort if unprotected. And extra warmth is obtainable by the addition of an ordinary merino vest and drawers beneath the sea-suit. One chief advantage of such a dress is the means it offers of correctly locating any dis- placement required either for non-swimmers, or on occasions of dangerous service by swimmers. Aquatic Clothing. 75 The usual system of cork or air belts is hope- lessly destructive of the outline essential to rapid locomotion in water. Any unfortunate wearer of such appliances, stuck nearly upright, like an empty bottle, drifts helplessly with wind and tide, and may die from mere inability to reach the shore. It will be seen from the draw- ing that a tube of air along the back, and a pipe communicating with the mouth, enables a tired swimmer at once to make use of displace- ment, causing a minimum of obstruction to locomotion. If the displacement instead of being placed in a ridge like a fish back, was supplied by a net-work of air-tubes between the woollen webb and rubber skin, it would, acting as a noncon- ductor, give much greater warmth to the wearer. The reader will easily understand from this description, wherein this sea-suit differs from the " Merriman Dress " exhibited by Captain Boy- ton. That gentleman is an excellent and most energetic exhibitor, and the chief merit of the dress is the protection from cold it affords ; but it seriously impedes locomotion, it precludes all possibility of following and saving any non- swimmer who has sunk, and its price, fifteen pounds, is prohibitory. The dress I have designed for plate-swimmers is supplied by Messrs. Cording, of 125, Regent Street, London, for sixty-three shillings. I have found it very 76 Plate- Swimming. seviceable when practising in a rough sea, and it is little or no impediment to a plate-swimmer's progress whether under water or on surface. It is not patented, and I trust it will be made and improved on by others. It is to be regretted that there is no recognized authority or ruling body for swimming regulation and government, such as the Jockey Club for turf questions, and the Marylebone Club for cricket. If the London Swimming Clubs were asso- ciated, sending representatives to a central committee in proportion to their numbers, and contributing towards prizes both for profes- sionals and amateurs, contests might be system- atised, public interest in them aroused, and means sufficient found to stimulate and reward exceptional merit either with credit or coin. We should not then have the farce of several claimants advertising themselves as champions of the same distance or the same feat in nata- tion, and squabbling in the press as to their re- spective merits. The title of " champion " would be an honour if limited to recognized test distances, such as the hundred yards, mile, and long distance at sea. A championship for pre-eminence in diving would probably also be acknowledged, due note being taken of its various kinds. Aquatic entertainments have already Aquatic Clothing. 77 very popular wherever well organized, and atten- tion is given to variety and novelty in the char- acter of the performances. The routine programme for London appears to be, handicap racing, fancy swimming, plung- ing, diving for eggs, undressing in water, the " Monte Christo " trick, tub racing, and what is called the saving of life illustration ; this last bearing no resemblance to reality, the part of victim being performed by some accomplished swimmer, the whole process looks deceptively easy, the true difficulties of such an undertaking never appearing in the representation. But all practice of the kind is useful, if the illustration be defective, and with a view to pro- moting activity, readiness and familiarity with recurring unexpected immersion, I can strongly recommend to entertainment organizers, the Indian practice of " Mussuk riding." " Mussuks " are the tanned goat skins used by Indian water carriers, which, if filled with air, can be ridden in the water either crossed-legged, or sideways. A practised rider will spring on to a Mussuk from the bank, sink overhead, but rise again firmly seated on " goatback." But the struggles of a novice, either to mount or keep his balance, the gravity of his countenance, and the effects of gravity on his person, his solemn persistence and frequent ducking, are sometimes ludicrous beyond description. 78 Plate-Swimming. In tournaments, each tries to put the head of his opponent under water, and if two grappling go under together, the last head visible, if only for a second, wins the bout. In racing with sides, say three against three, the time of each is taken by the last of that side " home," so that even two practised riders may have to support and push along a weak brother, whose perpetual fallings off, though dis- tressing to his side, are generally highly ap- plauded by the spectators. Handicapping is perhaps a necessary evil, though the honour to the competitor of winning such a race, is not self-evident, if the cause of his doing so consists in swimming so badly that he is let in with a start which the others cannot make up. It might vary the monotony of this kind of match if the competitors carried belts of different weights, in lieu of getting time allowance, and so swam shoulder to shoulder through the greater part of, if not throughout, the contest. 79 CHAPTER VII. ANIMAL SWIMMING. AQUATIC birds, putting aside mere waders, are all web-footed, and may be roughly divided into, firstly, those which swim by means of the feet only, their wings being large and not shaped for use as flippers, such as ducks, geese, and swans, gulls, cary chickens, &c. &c. ; their speed is very small, even human swimmers being able to catch them when disabled for flying. Secondly, the puffins, guillemots, razor-bills, and divers generally, with narrow, clean cut, closely feathered wings, \vhich they use freely underwater; they have great speed in swimming coming out, as a rule, after diving as clean and smooth as fish. Thirdly, some few of the auks and penguins, or booby tribe, use their wings only as fins for swimming, being too small for flying, some even having no quill feathers, and the wing, in proportion to their size being no larger than the flippers of the otaries, or sea-lions. The public have now a good opportunity of 8o Plate-Swimming. studying the swimming action under water of guillemots, at the Brighton Aquarium. They can there see to what extent wing action assi- milates to, or differs from, rigid plates, and flippers such as those of the turtles. The guillemots are perpetually moving about on the surface in their tank, using the feet only for propulsion, but directly they pass below the surface, the feet lie back motionless and they fly about under water, never closing the wings, but progressing with rapidity by the effective pressure of the upper and lower surface inclining alternately during upward and downward stroke. The film of air between their feathers and the the water looking like molten silver, and giving off bubbles continuously as they move. There is a fine specimen of the otaria jubata, or great sea-lion in the Regent's Park Zoolo- gical Gardens. This animal, though appearing when seated in a chair, as in the well known photograph by Mr. F. York of Netting Hill, only about five feet long in body, is, when extended to full length in the water, nine feet and a half from nose to end of foot fins, weighing over 200 pounds ; the flippers or fore arms are each two feet long and nine inches in width, the end section of these flip- pers, forming sixteen inches of the said two feet, is in skeleton a gigantic hand, the five fingers and their respective nails being dis- Animal Swimming. 81 tinctly indicated, but there being no joints to the fingers they form practically a swimming plate. The feet flippers are each twenty inches in length, but the five fingers or toes have skin hanging some inches beyond the nails ; this is possibly the result of confinement, as newly caught specimens are without it. At first sight it is difficult to realize the pos- sibility of such a creature pursuing and catching fish for food, but any doubt is quickly removed in watching the marvellous agility and rapidity of movement in water of the smaller sea-lion, or otaria pulcilla, which is in the same tank. This little animal has a more pointed head and slim- mer body than his companion, and skips through the water, after food which is thrown right and left for it, almost as lightly as a flying fish. The affection of these animals for their late keeper, Leconte, was very remarkable ; they used to perform a most ludicrous dance on the wall of their tank, jumping for joy, when they saw him coming, and when he turned to go, the larger one sometimes would lay hold of his clothes with its teeth to stop him. As regards the action of beavers, I looked through a number of zoological works in order to ascertain the precise manner in which they swim, and found a variety of superstitions not very creditable to modern publications, but no Detail whatever of the obvious indications G 82 Plate- Swimming. offered by their shape as to their manner of swimming. I read that they swam with their hind feet, that the tail was used for guiding them when swimming, and also for smoothing the mud with which their houses are built In fact that it performed the functions of a trowel and a tiller. An examination of the animal itself in the Zoological Gardens, and the ocular test of watching its action, disproved much of this detail. The ihind feet, though webbed, have but a small pressure area, as compared with the tail, which is flat, covered with scales, ten inches long and about five across and of an oval shape ; its pressure area is about forty square inches, and in swimming the animal sculls itself as palpably and unmistakably as is the case when a man uses an oar in the stern of a boat. The tail in fact is not a rudder but a propeller. It will readily be understood that this scull- ing is for the purpose of continuity, or sustaining acquired momentum, a much more economical application of power than the intermittent action of paddling. All warm blooded aquatic mammals, seals, walrusses, otaries, hippopotami, dugongs, &c. &c. &c., close the nostrils at will. This is of course essential \ where >f subaqueous turnings oftelTdirectlhe nostrils upwards, because water Animal Swimming. 83 would, if they were not closed, instantly replace the air in them and so find its way to the air passages of the lungs. One of our best fancy swimmers says, he is frequently troubled by this difficulty when practising his evolutions. All the pearl divers use nose pincers of bone, which hang round the neck by a string, and are slipped on to the nose before diving. The nose pincers shown at p. 58, were designed to meet this inconvenience, they are made of sheet vulcanite, being easily cut out with the aid of a small saw, the edges are filed round, and they are moulded to shape after dipping in scalding water, cold water setting them immediately. It is as easy to pass under water from surface when swimming on the back as when swimming on the chest, if using plates, and this enables the swimmer to look out from under water like a seal, but if attempted without closing the nostrils it would cause instant choking. The public are often misled as to the possi- bilities of human swimming by reports of distances and times taken from performances in tideways or streams, all mention of the favouring current being omitted, while credit is sometimes claimed for the accomplishment of rates of speed when the results announced are based on the most slipslop observation. G 2 84 Plate-Swimming. Mr. A. G. Payne was the first to sweep aside much delusion on this point by the stern logic of tested and registered facts, quoted in the work he edited for Captain Webb. We may take it as a deduction from our records of the art, that no one has ever yet accomplished two miles within the hour in still water. In fact that man is, looking to his size and weight, about the feeblest and slowest of swimming animals. A large retriever dog would weigh about half as much as a man, yet is sometimes able to beat him in the water, as shown in the follow- ing account from the Sportsman, of a match made last summer. "HARRY PARKER v. MR. EADE'S DOG, FOR 50. " Such a match as that contended at the Welsh Harp, Hendon, on Saturday last, is, we believe, without pre- cedent. Certainly in recent years nothing of the kind has been chronicled, and, therefore, the issue afforded the greater surprise, resulting as it did, in the defeat of the man. That a dog could compete with any chance of success against a moderately good swimmer many were loth to believe, and, although conceded a start on this occasion, the almost unanimous feeling was with the biped. In fact, it was generally considered a "good thing " for Parker, who, as a professional swimmer, has taken very high honours, and is at the present time teaching the art of natation at both the Peckham and Kennington Baths. The articles stipulated that Parker should concede to the dog a start of 30 seconds in half a mile, the time to count from the moment the dog entered Animal Swimming. 85 the water and not from any signal tendered by the starter. Mr. Eade has named his dog ' Now Then/ and he tells a very interesting story of the manner in which he first dis- covered the powerful merits of his animal in water. It appears from his account that being some distance off Margate in a boat accompanied by the dog, he unfor- tunately lost his two sculls, and how to reach the shore he was at a loss to know for some time, until the bright idea struck him of utilizing the animal. This he did by means of his pocket handkerchief which he attached to the collar of ' Now Then/ who was known to retrieve well in water, and, as a means of keeping him in the right direction, his owner cut the stretcher up into numerous pieces, and so threw them just ahead of the dog, who being thus encouraged on his way, successfully towed the boat to shore. 'Now Then/ a half-bred retriever, is black, and shows remarkable strength in the fore arm, while his paws, when spread, are unusually large, and, in swimming, the whole of his back is visible. A straight half mile had been marked out with flags denoting the course, and at a few minutes past six the dog leaped off the punt, his owner leaning over the stern of a skiff which preceded the animal, enticed him with cooked liver, and in the half minute allowed he travelled nearly forty yards, the speed with which he propelled himself being par- ticularly noticeable. Parker slightly reduced the gap in three hundred yards, but keeping a beautifully straight course, the dog began now to positively draw away, and to the chagrin of the swimmer's backers at the end of about 450 yards the dog was seventy ahead. After this Parker eased, and never again went at top-speed to the end of the journey, the dog thus winning very easily in 14 minutes 3 seconds." The best natural illustration of plate-swim- ming is shown by the turtle family. 86 Plate-Swimming. The shape of the turtle is that of a swimming plate ; moving easily edgeways in water, but having great vertical stability, this enables it to make both the up and down blow of its front flippers very effective. The action of the turtle when moving slowly is like that of the frog, on the diagonal, i.e., the left front and right rear flippers move together, but like the frog also, the turtle works its flippers in pairs whenever doing its best, and this is also found advantageous by human swimmers with plates. Mr. Winwood Reade, who visited Corisco near the Gaboon on the West African coast, gives a good idea of the speed of this animal. He had been introduced to a great turtle har- pooner called " Abauhi " and he describes their proceedings as follows : " When the moon had risen above the plantain trees, Abauhi came forth carrying a couple of long spears and followed by two men, with paddles in their hands. He led the way down to the beach and pushed a small canoe into the water. He then asked me if I could swim, as canoes are often upset in the turtle-spearing business. I was obliged to reply that I could not. He seemed sur- prised at my venturing at all on the water in such a case, and advised me to go home again. Finding that I was not inclined to do this, he placed me in the bottom of the canoe, holding the sides with my hands, and told me not to stir after we had once started. His injunction was quite unnecessary, for, as we wobbled along in this tiniest Animal Swimming. 87 of vessels, it seemed to me that only a succession of miracles kept it from capsizing. Abauhi stood up in the prow, with a foot on each gunwale. Two mortal hours and nothing had been seen. Clouds circled and threat- ened to obscure the moon. My joints became horribly cramped ; and when I looked at the dim water over which we passed, I could not believe that it was possible to see a turtle where I could see only the reflection of the stars. Suddenly the spear was hurled into the water. The men gave a yell. Something large and black leapt through the air, and fell into the sea with a prodigous splash. Abauhi .snatched up a spare paddle and the canoe seemed to fly. In front could be seen a cloud of white foam skimming along the surface of the sea. This was the staff of the spear, the turtle being in the water underneath. The iron spearhead with its small barb is tied by a string to the staff or butt, when the turtle is struck the spearhead remains in the flesh, and the staff retained by the string floats on the surface. " After a second spear had been thrown, and a second burst of speed followed, the turtle was pulled into the canoe." Some stress has been laid on the question of the speed of the turtle, because a friend hearing that the action of these flippers followed to some extent that indicated by those of the turtle exclaimed, " Oh but they are such very slow animals!" He probably confounded the tortoise, renowned in fable, with the turtle. Perhaps the most important example of the natural mechanism of animal locomotion in water is that of the fish's tail. Among the 88 Plate- Swimming. illustrations in woodcut, page 58, will be seen a propeller called the " fish tail flipper." Now what is the true action of a fish's tail ? I believe it has never yet been correctly de- scribed. There is an excellent work on animal loco- motion by Dr. Pettigrew, published by Messrs. H. S. King & Co., to which I can refer my readers for much that is interesting, but, having analyzed for myself the action of the tail of a fish, I cannot agree with Dr. Pettigrew as to the correctness of his theory on the subject. Dr. Pettigrew states that all writers since the time of Borelli, whose work " De Motu Ani- malium" was published at Rome in 1680, have adopted his assertion that, " The fish in swim- ming causes its tail to vibrate on either side of a given line, very much as a rudder may be made to oscillate by moving its tiller." And, he adds, "according to this, the commonly received view, the tail would experience a greater degree of resistance during the back stroke, i.e., when it is flexed and carried away from the axis of motion d, c y f than it would during the forward stroke, or when it is extended and carried towards the axis of motion. This follows because the concave surface of the tail is applied to the water during what is termed BORELLIS FISH Animal Swimming. 91 the back or non-effective stroke, and the convex surface during what is termed the forward or effective stroke. This is just the opposite of what actually happens, and led Sir John Lub- bock to declare that there was a period in which the action of the tail dragged the fish backwards, which, of course, is erroneous." That I may not make a misleading interpre- tation of Dr. Pettigrew's views, I have given a copy of his diagram on the subject and will use his own words in describing it. " By always directing the concavity of the tail s and / towards the axis of motion a b during extension, and its convexity c and v, away from the axis of motion a b during flexion, the fish exerts a maximum of propelling power with a minimum of slip. In extension of the tail the caudal curve s, is reduced as the tail travels toward the line a b in flexion. A new curve v is formed as the tail travels from the line a b, while the tail travels from s in the direction t the head travels from d in the direction w. There is therefore a period, momentary it must be, when both the cephalic and caudal curves are reduced, and the body of the fish is straight, and free to advance without impediment." Now it is physically impossible for a fish to strike from s to a b with its tail concaved at all. Q2 Plate- Swimming. The elasticity alone of the digits or rays in the tail, to say nothing of the power and pressure of the water, suffice to open it the instant it reaches the limit of its sweep. The recovery or transfer of pressure to reverse side is caused by a slight flexion of the caudal vertebrae, and the tail passes from s past the axis of progression to t ; with a rearward reflexion of its effective side throughout the stroke. In fact the tail is never coincident with the line of progression, except when the fish is gliding with acquired momentum or at rest. I show what I believe to be the true tail action of fishes in diagram No. 3 of annexed illustration, as also its possible application to the reciprocating fish- tail action of human legs. The " recovery" on one side being effected by bending the knee joint, or the other, by bending both it and the ankle joint. The action depicted in Dr. Pettigrew's dia- gram is supposed to be that of the sturgeon, exaggerated probably to emphasize the theory enunciated, as it rather resembles the action of the dog-fish, which seems to swim with the entire body, somewhat like the eel. The fish I have chosen for illustration is the gurnet. It has two pair of enormous pectoral fins, between which on each side lie the curious little claws by which it walks ; these are all Animal Swimming. 93 furled up out of the way close along the body, as soon as it begins to travel forwards in swim- ming, the entire progression being effected by the tail flexions. These begin at two thirds of the entire length from the tail, and a visit to almost any aquarium will place the character of these flexions beyond dispute by ocular demonstra- tion. The great head wags in unison with the caudal movement, turning slightly to the side to which the tail is carried, exactly as the prow of a boat follows the right and left sweep of the sculler's oar, and quaintly recalling one of Lord Dundreary's confusions, in which he reflects as to why a dog wags his tail, and then supplies, the mechanical explanation, that " he is bigger than his tail," " and unless the tail was smaller than the dog, of course the tail would wag the dog." The .swimming action of the mackerel also shows, to my mind very clearly, that propulsion is effected by passing the blade of the tail across the axis of progression with a rearward reflection of its effective side. I shall be glad if my own interpretation be freely criticized and any inaccuracies corrected. There can be no doubt but that we may learn a valuable lesson from the unquestioning credulity of those who for 200 years accepted the very unmechanical superstition of Borelli, merely 94 Plate- Swimming. because it had been enunciated by authority ; it proves the truth of Huxley's assertion that, in science at least, " scepticism is the only phase of mind promising safety, and blind faith the one unpardonable sin.'* 95 CHAPTER VIII. VALEDICTORY. " Three wives sat up in the lighthouse tow'r, And they trimm'd the lamps as the sun went down : They look'd at the squall, and they look'd at the show'r, And the night-rack came rolling up ragged and brown ; But men must work and women must weep, Where there's little to earn and many to keep, Though the harbour-bar be moaning." " Three corpses lay out on the shining sands In the morning gleam as the tide went down, And the women are weeping and wringing their hands For those who will never come back to the town ; Yet men must work and women must weep, Though storms be sudden, and waters deep, And the harbour-bar be moaning. IT may be as well to state clearly what is the present position and future promise of this system of aiding swimmers, i.e. what is already demonstrated and what hoped for. The inven- tor has sufficiently shown that the use of swim- ming-plates is not, as one critic to whom the 96 Plate-Swimming. suggestion was submitted, declared, "anatomi- cally impossible for human beings," but an easily acquired and agreeable accomplishment. It has been proved to demonstration by repeated practical test, that lads who could not swim 100 yards unassisted, can complete four times that distance with plates ; that an amateur with little practice, whose best time for 100 yards unaided was 132 seconds, has done the same distance plate-swimming in 83, while a profes- sional has reduced his time for 100 yards in the same way by thirteen seconds, and the writer can safely defy any unaided swimmer to accomplish the feat of swimming even twenty yards with 50 Ibs. of iron weights tied round his neck, though he has himself easily achieved more than this test of the power of plate-swim- ming. If any one examines what is called the annual wreck chart of the British Islands, compiled from the Board of Trade Register by the officials of the Life-Boat Institution, he will be struck Firstly, by the enormous amount of the casualties reported in a single twelvemonth's record. The quarterly journal of the Life Boat for November last says : " The annual average number of wrecks on the coasts of the United Kingdom reported since 1855, divided into four periods of five Valedictory. 97 years, may thus be given. Between 1855 and 1859, th e number was 6,023, giving an average of 1,204 a year. Between 1860 and 1864 the number was 7,415, or an average of 1,483 ; between 1865, and 1869, 9,467, or a yearly average of 1,893 ; and between 1870 and 1874-5, 10,428, giving in that period an average of 2,085 wrecks each year. Secondly, by the fact that despite the heroic readiness of our life-boat crews, and the numer- ous stations which the Royal Life Boat Institu- tion has established, there must remain many rocks and shoals unguarded. Thirdly, that throughout the coast lines of the world there are none so guarded by life- boats as the coast of England. There is many a wild stretch of strand the dwellers by which may, at any moment during stormy weather, be startled from the half-awak- ened pity which a knowledge of distant danger arouses, to quick throbbing sympathy for pre- sent trouble, by the sound of minute guns at sea. Then, as men and women hurry to the beach, or watch from the cliffs, midst driving wind or blinding rain, striving to trace the outlines of the doomed vessel, through the hoarse roar of the trampling surf they hear again the faint echoes of that solemn appeal from those in mortal danger to their fellow men, where no life- boat is available, where no H 98 Plate-Swimming. ordinary boat could live, and where strenuous if almost hopeless effort, would be a relief from pain. It was on just such a spot, and in just such a storm, that the Royal Charter was lost on the coast of Wales. The Royal Charter was an iron passenger steamer, and when driven on to the rocks of Anglesey she had on board 494 souls, principally returned emigrants, some of them seeking, after life-long exile, the haven of home. Thirty-nine only were saved out of that community, and the manner of their rescue is the lesson on which I would now insist. One gallant swimmer, a Maltese sailor of the crew, named Joseph Rodgers, volunteered the attempt to carry a line to shore, and struggled through that raging sea to land, with the means of communication fastened to his waist, so enabling a hawser and guiding lines to be carried across for slinging to shore the few who were snatched from destruction. Many more might have of course escaped by the same means but for the rapidity with which the iron fragments of the wreck were engulphed after she crashed on to the rocks. Surely what was barely possible for even the boldest swimmer unaided, may be rendered more feasible for such a volunteer if he 'were protected from cold by impervious tissue, pro- Valedictory. 99 tected from the possibility of lengthened im- mersion by air displacement, and supplied with propellers enabling him to force his way through a tide. It would, as a matter of course, be at the risk of his own life, even if so assisted, that a swimmer would commit himself to the sea ; but I feel confident that many would be found to accept the risk even of attempting communi- cation from shore to the ship, and much as we may value the hope of any single life being so saved, we may reckon far higher the thought that such volunteers can be found. One life so sacrificed for men would be far more for human- ity than many a life so saved. Supposing a single set of these appliances placed either in a passenger boat or a pleasure yacht, there are numerous situations in which they could be used with pleasure or profit, to say nothing of their being in reserve for such desperate extremity as that described. There are now no covered cold water swim- ming baths for London. There are two small cold plunge baths, the " Nell Gwynne " in Cold Bath Square, Clerkenwell, which is fifteen feet by sixteen, and only five feet deep ; and the old Roman Bath, Strand Lane, Strand, eight feet by fourteen, and four feet six inches deep. The old " Royal bath," Newgate Street, has, like the "Peerless Pool" before it, been swept H 2 I OO Plate- Swimming. away to make room for improved buildings, and a letter addressed to the Manager of the Cam- den bath was returned through the dead-letter office marked " deceased." For open air bathing, in stagnant water of dubious character, the Hampstead Ponds, or those in Victoria Park, or the Serpentine during early morning, and, bar- ring temporary financial collapse, the Alexandra Park Bath, are available during summer. While swimming races are at times allowed at the "Welsh Harp" Hendon, at the Crystal Palace, and in the Thames. In the Appendix will be found a list of London tepid water swimming baths in alpha- betical order, with their addresses and dimen- sions ; these latter have in most instances been tested for this list, in some cases the measure- ments are taken from Dr. Dudgeon's " Swimming Baths of London," published seven years ago. Whenever remarkable speed in swimming is quoted on the strength of time taken in a bath, it is of importance to test its exact length, and not accept all that is entered on pro- grammes of entertainment. Thus, with the largest of our baths, that at Brixton, the times reported might prove delusive, unless it be remembered that "for racing purposes" it is called 50 yards long, but being unfortunately four feet less by measurement, the competitors in a 500 yard race go 40 feet short of that distance. Valedictory. 10 1 The weak point of our baths is their want of depth, the maximum of all but two being six feet only, which offers little facility for practice under water. Diving into a clear pool on a fine day, with the sunlight streaming into and illuminating the water, is very enjoyable, but practising in the same pool during dull foggy weather affords comparatively little pleasure. This is just the difference between the modern clear bright look- ing bath lined with white encaustic tiles, and the dismal sort of hole which the ancient ill- ventilated, ill-lighted, and stone or wood lined style of bath presented. It is certainly a remarkable fact that while there are more than 40 tepid swimming baths, great and small, in London, there does not exist even one in Paris. Yet, so far as what is called society is concerned, a larger proportion of young Paris can swim than of young London; this arises in part from their having a cleaner river at their doors. During the brief season that their floating baths are on the Seine, the French spend more time, and enjoy more thoroughly life in the water, than is ever witnessed in this country. Very much of the credit of our valuable system of tepid swimming baths is due to our parish authorities. The best baths now in London are those of Marylebone and Pad- 102 Plate- Swimming. dington. When, therefore, easy strictures are levelled by critics on parochial parliaments, common justice and common sense will surely allow fair credit to those of our vestries which have given practical effect to enlightened views of administration and sanitation, and have estimated the benefits conferred by such in- stitutions as these public baths, by a higher measure than the mere return in pounds, shillings, and pence, to the communities they govern. At the Marylebone establishment there are not only the " Gem " bath of 73 feet long for gentlemen, and one of 45 feet for ladies, but a second-class bath of tepid water, 66 feet in length, the admittance to which costs three- pence. Also a third class bath of the same dimensions, the charge for which is two pence only. All of these are admirably light, airy, and clean ; even the third class bath being lined with white enamel bricks. The Bath Commissioners appropriately quote on their handbills these words of Dr. Abernethy : "Next to eating and sleeping, the swimming bath ranks among the very foremost of the necessaries and supports of life ; it is of far higher consequence, and of more general utility, than any kind of manual exercise, gymnastic or sport. It affects the system more power- fully than these, even in the very points wherein their excellence consists ; and it is applicable in a thousand circumstances where they are not. It does not supersede, Valedictory. 103 but it ought to come before these other practices. Time should be therefore found for the bath among the regular occupations of life ; it ought to be a permanent institu- tion, ranking immediately after the prime necessaries of our being. Either daily, or several times a week, should every one repair to it, in some shape or other, either at morn, mid-day, or evening, according to strength and leisure. There certainly does not exist a greater device in the art of living, or a greater instrument for securing a vigorous and buoyant existence. It is one of the most powerful diversions to the current of business occupation ; it can suspend for a time the pressure of our pursuits and anxieties, and return us fresh for the enjoyment of our other delights. To the three varieties of state which our bodies daily pass through, eating, working, sleeping, it would add a fourth, luxurious in itself, and increasing the relish for all the rest. It would contribute to realize the perfect definition of a good animal existence, which is, to have the appetite always fresh for whatever may be before it. The health of the mind must be based in the first place on the health of the body ; mental occupation and refined enjoyments turn into gall and bitterness, if not supported by the freshness and vigour of the physical frame." No physician need wish for a better epitaph or a nobler monument to his memory than this practically, if indirectly, accorded to Abernethy by the vestry of Marylebone. The plan is throughout the same at the Bayswater establishment, the charges are iden- tical, but the baths considerably larger. On the other hand it is matter for regret that 1 04 Plate-Swimming. the use of our natural facilities for open air swimming, river, canals, and park lakes, is practically prohibited to the population. Any poor little waif who attempts a clandestine swim in or near London, is hunted off by the police. While bathing even for the privileged few at the restricted corners provided in our parks, is, after eight in the morning, too " shock- ing " to be thought of. Seaside " bumbledom " sometimes ' drives away to an inconvenient distance, or an incon- venient hour, all bathing and bathers who can- not afford to hire machines, while, despite all this misdirected repression, there is much coarse indifference to what is befitting a civilized community ; I have seen much that is unbe- coming even in first class baths in this country. Surely the proper remedy is simply to enforce the continental system of decent dress in the water. The very poorest casual who ever bene- fitted by free bathing can afford a pair of " calegons " in some form ; even if as ragged as his everyday habiliments, or perchance in part those habiliments themselves, they would be at any rate as " decent" as his costume in Regent Street. When aquatic entertainments are given, and ladies admitted, " university dress " is very properly insisted on, and some sort of costume should at all times be compulsory. Valedictory. 105 So might we ultimately overcome that foul- thoughted vulgarity which leads the middle class British Philistine abroad to find cause of offence in ladies and gentlemen, even though fully dressed, entering the sea from the same bathing stations at Dieppe, or Ostend. So may we hope in time to escape his own improprieties when he airs his language devoid of aitches, and his person devoid of drawers, among the gentle- men swimmers at our public baths. It is earnestly to be hoped that some pro- vision or protection for common rights in water may be arranged, its reckless pollution more sternly punished, and free bathing places pro- vided wherever natural facilities exist. The value of patches of common land to the community is now fully recognized, and the rights of the public have been nobly vindicated by the City authorities and the Metropolitan Board in the Epping Forest and other cases. It is fortunate that any have been found honest enough, wealthy enough, and powerful enough, to compel part restitution of such misappropriations ; to speak fearlessly, " judge righteously, and plead the cause of the poor and needy." But for such defence of the inter- ests of the people, there must soon have been, not scores, but many thousands in this country, doomed to live out their lot on earth, from the 1 06 Plate- Swimming. cradle to the grave, in squalid dwellings, and paved streets, or roads alternately muddy and dusty, warned against leaving these pleasant paths by threats of prosecution with the utmost rigour of the law. If some spot could be allotted for free bath- ing, during the summer months, from steps below the embankment, it would not only be a blessing to many of the poorest in London, but might perhaps hasten that happy time when a peremptory termination will be put to the system of river pollution above the metropolis, which is now perpetuated by the correlation of selfishness, and apathy, ignorance and imbe- cility, in those concerned therewith. It may be mentioned in conclusion, that should any of my London readers be desirous of acquiring the accomplishment of plate-swim- ming, they can readily do so by visiting during the summer either the Paddington or Maryle- bone baths ; Messrs. Silver having, by permission of the authorities, arranged to place a small number of plates at each for hire at sixpence the set. And should beginners be unable to learn, or work out the system by practice for themselves, Mr. C. Whyte of the former bath, and Mr. J.
