When an animal is know n to be subject to overreaching, he should 

 never be driven fast w ithout (jiiarter boots, which are specially made 

 for the protection of the heels and (juarters. 



If there is a disposition to " <rrab " the forward shoes, the tionbU- 

 may be remedied by Iwn in<r the heels of these shoes made as short as 

 j)ossible, uhile the toe of the hind foot should project well over the 

 sJioe. When circumstances permit of their use. the fore feet may be 

 shod with the "tii)s" instead of the conmion shoe, as desci-ibcd in 

 treatment for contract^'d heels. 



CALK WOUNDS. 



Horses wearino^ sIuk's w ith sharp calks are liable to wound- of the 

 coronary reeion, cither from tramplinii on themselves or on each 

 other. These injuries are most common in heaw draft horses, espe- 

 lially on rough roads and slippery streets. The fore feet are more 

 liable than the hind ones, and the seat of injury is commonly on 

 the (juarters. In the hind feet the wound often results from the 

 juiimal resting with the heel of one foot set diiectly oxer the front 

 of the other. In these cases the injinw is generally close to the horn, 

 and often involves the coronary band, the sensitive lamin:e. the 

 extensor tendon, and even the collin bone. 



Treatrtient. — Preventive measin*es include the use of boots to pro- 

 tect the coronet of the hind foot and of a blunt calk on the outside 

 lieel of the fore .sh(K'. since this is genei-.illy tlie offending instru- 

 ment when the fore feet are injured. If the wound is not deep 

 and the soreness slight, cold-water bandages and a light protecti\e 

 dressing, such as carboli/.ed cosmoline. will be all that is needed. 

 When the injiUT is deep, followed by inflammation and suppuration 

 of the coronaiy band, lateral cartilages, sensitive laminie, etc., active 

 measures must be revolted to. Cold, astringent baths, made by 

 adtiing 2 ounce,s of sulphate of iron to 1 gallon of water, should be 

 used, followed by poultices, if it is necessary t^ ha.sten the cleansing 

 of the wound by stinudating the sloughing jirocess. If the wound 

 is deep between the horn and the skin, esjiecially over the ant<»rior 

 tendon, the horn .<;hould be cut away so that the injured tissues may 

 be exposed. The sub.seqnent treatn)ent in these cases should follow 

 the dire<^ions given in the article on toe cracks. 



FROSTBITES. 



Excepting the eai-s, the feet and legs are about the only parts of 



the horse liable to become frostbitten. Ihe ca.ses m(»st commonly 



seen are foiiml in cities. espe<ially among cai- horses, where salt is 



used for the purpose (»f melting the snow on curves and switches.
