The wonder rather is, considerin-r the im- i'loprr and unnaturally shaped feet and shoes, that there "are an/- sound. ' Another of the 'crroi-.?ih shoeing which I' found current when I rame here was the want 6f a tip or pr6jection turned up, on the poin, of the shoe to for an abutment against the too of the hoof. It .scemod to me that in respect of tiiis the smiths had turned the shoe wrong side up, g.vmg a tip downwards where nature .iever designed it to be, and denynig one upwards where it was essentially wanted. As from the long toes so from this also the fore feet are the greatest suflerers. I liavc already mentioned the function of the fore limbs to be mainlv the support of the weight, and its transference forward from point to point durmg the motion of the animal. In doing this a considerable degree of concussion is inflicted upon the foot every time it striken the ground. The direction of this concussion is neilher right down- ward nor right forward, but between the two, partaking of the hori- /ontal motion of the body of the animal along the roud, and of the perpendicular direction of the descent of his wcig'it. Everyone knows the additional power of rosislihg or sustaining concussion and weight any (ibrous substance has if struck or pressed m tliR direction of the fibres bjsidos if acted on in any other. The hoof of the horse is compjsod of an infinite number of dense fibres, strongly agglutinated together ; and to enable the foot with the greate^'t advantage to meet and support the concussion there is when it^strikes the ground, these fibres are every one of them so placed in the unshod' loot as to receive the sliock directly on their end tliis, the front part of the hoof whore the 1 greatest is twice or thrice as thick and str .„ __ its slope indicating exactly the direction of tlTe de ••eight. , In addition to" brce of the concusr>in it' ■ong as the side and lieels, cent of the horses [9J Now all this thickening p.nd strcnRthoning and sloping at the too of the fore foot is not without an obvious design, which is to enable it to roceivo without injury tiie shock upon it when the horse is thrown forcibly forward, as in leaping, galloping, or even hard trotting, os- pecially if down iiill, and by turning up a tip on the shoe as an abut- mont for the too to press against when it strikes the ground we make both shoo and foot to aot together in harmony, we save the shoe from being knocked off, and at the same time promote the natural action of the foot. In shooing without this simple expedient, we frustrate the design which nature evidently had in making the toe so strong, and throw the concussion this strength was designed to meet upon • the nail holds of the weaker parts of the foot, sides and heels. These have not only to support the weight of iho shoe but also to bear the force of the foot striking the ground ; and the shoe being found from these two causes more inclined to come off than is wished, resource is had to an extra amount of nailing, not only at the toes, where from the thickness and want of spring in the hoof it is harmless but round the quarters and even to the heels where by its pinching and fettering effects it is productive of the worst of consequences ; corns, contrac , tion and founder being its daily fruits. No disease is more certainly a consequence of shoeing than corns, and the number of horses lame from this heroisfal most beyond belief, I have met with them in feet where they had caused lameness for years and been shod over all the time without discovery. In such a case we may blame the shacr for oversight but not for wilful mis- doing; but what shall wo say when a corn is discovered, and to aome relieved by the knife, and then the shoe refixed on the very plan by which the evil was originally produced, yet such things happen not once or twice, but daily. Two causes mainly contribute to the production of corns; nailing of the shoe too far back by its preventing the spring of the foot is one. The other is unequal pressure of the shoe upon the sole and heels ; when both are combined corns are next to inevitable. A reason or at least a pretext for heel nailing I have already noticed. The extent to which it is carried and the uniformity of its occurrence show that those who produce it never entertain a doubt of its propriety, nor a suspicion that the hoof of the horse is an elastic and ofganiz^d structure contracting and expanding alternately at every step and consequently in proportion to the extent to which it is fixed and fettered. The unequal pressure between the hoof and shoe which leads to^ corns and other hurtful consequences may arise either from the shoe [10] being improperly made or the foot insufficiently parerd out. It is rarer that we meet with a shoe here on which an attempt has been made to form a seat for the sole, more rare still that the attempt is success- ful. The seat when tried to be made is commonly only a concaTC from given to the entire surface of the shoe next the hoof instead of extending only as far outward as the sole, and leaving a level rest for the edge of the crust, such shoes should be called scooped rathei than seated and are worse to make a horse go with, than even those flat made. But the cause of coma is often to be found in the way the foot is prepared. I have already adverted to the buttris as being instru- mental in the production of long toes. It is equally so in that of cdrns. Of this no better proof is needed than the disappearance of the one simultaneous with disuse of the other ; this has happened ge- nerally in Britain within the last thirty or forty years, and particularly in the practice of Reginiental shoeing. Professor Coleman of the Veterinary College of London, writing' in 1809 says : " There are very few horses that are not attacked with corns. This is so common a disease that nine hundred horses out of a thousand have it." Mr. Percival, Veterinary Surgeon to the First Life Guards, in his work on lameness in horses published last year says: "That faulty shoeing is the chief and predominant cause of eoorns cannot anywhere receive more satisfactory demonstration than in the Army. Corns and quittors and contracted feet were in former days as rife in the Cavalry as in other places, whereas at the present day these diseases are all but unknown to Veterinary Surgeons of Regiments ; and all is owmg to an amended practice of shoeing." My own experience, if it could add anything to the above is this : during seven years practice immediately preceeding my coming liere I did not meet with more than five or six casca of lameness from corns ; and in a record of more than a thousand cases that I kept during a part of the time, noting them in the order which I treated them, there is only one of corns, and that a slight one. Since I came here there are few days that I do not see horses lame from this cause, although it can be but a fractional part of the evil that comes under my ol-'?ervatio'.i. In blamlncr the buttris for producing corns and other evils, a few words of explanation is necessaiy. From the shape of this tool its- tendency in cleaning out a foot with it, is to cut away both crust and sole, bars heels and all to one level. In fact it is hardly possible when using it to leave one part more predominant than another, en- l^cially when it is the crust and bars that should be left and the sole t [U] internal agencies ,s by no means a stiff or rigid body, but springs and expands at every step, and along with thfs expan ion the Z d seen s and flattens out fro. the weigh, of the horse rest.ng on Z fort lZ:7'% """;'' ^'^ '^"^"^ °^ ^'^ -'« be not 'allowed for m fitung the shoe, either by a seat worked .„ the shoe itself, or by cleaning out the sole to a lower level than the crust, then the ole m us descent presses on the shoe, and the sensitive part inside is squeezed between it and the coffin bone. As the heel s par of the ^oun wh.ch expansion is greatest and the descent of the sole a^ coffin bone ™ost, and as the angle between the bar and crust i. t^e place from wh.ch the sole is with .eatest difficulty remov so it' •n the heels that the bru.sing ana ..rn producing action of bad shl^ .ng .s most to be met with. Yet I have seen on all part, of the si round near the crust bruises caused by pressure of' the Jle dol„ vards on the shoe. The way therefore in which the but^ a ds in' he production of corns is from its unfitness for effectually r mov p" tl^ more depressed parts of the unnecessaiy horny sole. T Je h^nds of a person aware of how the foot should be dressed, and whb w. 1 take the drawmg knife and rasp to give the sole, heel , and t5« the proper form after doing the rougher part of the work with Z bnttris. It IS aa efficient and useful tool, and so long as people aUow ^oX 1 r 'T^ ^^ ^"" ''' ''' ™^"^^' «^ a'timaMoutZ^' movmg the shoes, they can hardly expect it to be laid aside. I abuse however ,f better understood would be easier guarded againrt The common way in which I have seen feet prepared and shod o^e" ;L f" t""' Tr' ^' '''' °'^ ^^- the'bu'ttris is broug^ It „ n 7\ ''' '''"' ^'"'^ ^**^ ^'^««« '^^•"g -ft -d easily L get a hberal sUciag, a scoop is then taken out of the sole on eaclfsil extending nearly to the toe, and forming a uniform- concdve fromtte 2"t of the frog to the out edge of the crust, so that when, a scooped shoe IS placed on it, ir^tead of the foot and shoe presenting two lev^l surfaces to each other, they rest upon two thin edges, and even w^h the level shoe it is the thin out edge only of the crusl that bel the weight : this ...oojr.ng out of iho sides of the soles is all the implement can^convenientiy effect. It is not handy for rounding or shortening buck the too and so is seldom bid to do it, that part being.Ieft cntii oxcept a little out of th« sole surface which rather adds^han other. wise to Its projecting point ; neither is it available for cleanings out the aole from the angles between the heels and bars, leaving these part. [12] prominent to rest upon the shoe. All it can do here is to bring the parts to a uniform level, and this being done with the foot off the ground, the instant it is set down all the parts change their relative positions, and if the sole was left equally full as the crust and bars (parts designed to bear the horses weight,) it is now more so, and a week or two's work and growth brings such a degree of pressure on it as to bruise the sensitive sole underneath, rupturing some of the minute blood-vessels with which it is studded, and showing the evil that is done by the effusion of the blood through the pores of the horny sole as in the condition called corn. The foot being prepared in this way, the shoe is fitted (so far as it gets any fitting) to its elongated and pointed form, and being turned wrong side up so far as the shape of the toe goes, it is nailed as far back towards the heels as nails can safely be driven, and the same process being repeated time after time when the shoes are removed we have the long contracted mule looking feet produced that we see daily on our streets. A system of shoeing free from these defects is just as easy to prac- tice, equally cheap, and productive of far more satisfactory results. The following is an outline of its most important points. In making the shoes whether fore or hind, the elongated and pointed shape should be studiously avoided, even when from previous bad management the feet are contracted at the heels and flattened in on the sides to an extent admitting of only a partial restoration to the proper shape ; still the projecting point upon the toe can be dispensed with, and a broad and solid bearing given in front. The fore shoes if they have a concave seat should have a perfectly level bearing of the breadth of the crust round the outside. The hind shoes do not need seating as the hind feet have a greater concavity and less des- cent of the sole than the fore. Both fore and hind shoes should have a tip or projection turned up in front as a rest for the toe to bear against in the descent of the foot, and an aid to the nails in keeping it on. The web or body of the shoe stiould be of a uniform thick- ness all around, and when heel caulks are worn they should be both one length ; when only one caulking is worn the other heel of the shoe should be thickened up to the same level. When toe caulks are required either to give foot liold for heavy draught or for sharpening in winter, they should extend as far laterally as the breadth of the foot will admit, be as little prominent as may be to afford sufficient hold, be of a uniform depth from end to end, so that all parts bear equally on the ground, and have the bearing edge on the same level as a line drawn between the points of the heel caulks. [13] The fullering or grooving of the shoe is n useful device for secur- ing the even punching of the nail holes and protecting the heads Of the naih from wear. Beyond this I am not aware of any benefit from it, and it certainly has the disadvantage of weakening the shoe and facilitating its being worn down. In France, many parts of Britain, and in all the English Cavalry Regiments, the nail holes are simply punched and couriter-sunk without any groove or fuller and have a nail suited to the size and form of the hole. The shoe made thus has a greater solidity and durability, and I have little doubt will ultimately be the form preferred. But whether fullered or not there are one or two things about the punching of the nail holes not to be overlooked. They should all be so punched that the nails may enter the wall of the hoof on its inner edge. No nail hole should ever be seen on the seating of the shoe, nor nail in any part of the edge o* the sole. To do this properly requires some nicety as both the thick, ness and slope of the crust alter as we proceed from the toe to the heels, and it is one of the things much neglected in the making of shoes here, there being but few in which you will see a well gra- duated range of nail holes. A point worse managed however is the placing of the nail holes properly as regards their distance from the heels. No nail should ever be driven into the foot further back than its broadest part. This is a rule of nature's indication and she will not suffer its violation with impunity. Beliind the broadest part of the hoof the spring and expansion is such that it cannot be fettered or confined without harm ; yet we seldom see a shoe made here that has not one or two nails into the forbidden ground, and often they arc nailed to the very heels. As an instance : a gentleman drore a horse from Fredericton to 1st. John last winter who had been shod the day before leaving. He was two days on the way, and before reaching here was lame on all four feet. On taking off the shoes no special cause of lameness was found in any of the feet except the fettering effects of the nails ; but these were driven to within half an inch of the heel caulks, so as to destroy entirety the natural action of the foot. In another case a gentleman's horse in Portland had been lame from corns noboby knew how long, as the hoof was so over-grown that the corns had never been discovered. In this case tho fore feet admitted of being shortened back more than an inch, and a propor- tional quantity taken off the sole ; and the nail holes of the old shoe instead of extending only hilf round as they should have done, occu- pied more than two-thiru - !.
