As this is of frequent occurrence, which we know from the number of men who come to us each year for advice, and, as men are often wrongly advised by "hoss doctors" looking for a job, we will repeat the advice we have always given, although nature almost invariably cheated us out of a job. In rupture, either of the scrotum or the navel, unless there is pain from strangulation of the intestines, our plan is to let it alone; and we feel safe in saying that fully three-fourths of such cases will disappear by the end of a year, thus saving the colt the pain and the owner the expense and risk of an operation. If, at the end of a year, there has been no decrease in the size of the sac, then we advise an operation on a rupture in either of the localities mentioned. Hut there is a difference in the manner of operating.

If the rupture is at the navel the colt must be turned upon its back and the contents of the sac returned through the opening into the abdominal cavity; the loose skin should then be drawn up and a strong cord tied several times around it as close as possible to the abdominal wall, and drawn tight enough to stop the circulation. If the cord is passed through the skin with a large needle it will prevent slipping, and in about ten days the sac will drop off and the part will heal over.

In rupture of the scrotum the operation is that of castration in case of a rupture, and should not be undertaken by any one without some knowledge of the parts. The colt should be cast and tied as for ordinary castration; turn him upon his back, return the intestines, then open the sac all except the last covering of the testicle. This should be stripped carefully by the fingers directly up to the opening of the abdominal wall and there secured by tying as in rupture of the navel; then the cord of the testicle can be severed two inches below. When both testicles have been removed the colt should be allowed to rise. Treat the same as in ordinary castration.
