As polo ponies are the only working horses which are usually wintered, I shall here refer only to them. Mr. E. D. Miller's Modem Polo contains such an able and full account of this subject, that I need only touch on the general conclusions of that author. The pony may spend the first two months of the slack time from the 1st September to the 1st April, at grass without corn, provided that the "keep" is plentiful, and the animal is young, vigorous and acclimatised. If he finds the exposure trying, he may have a couple of feeds of corn daily. Mr. Miller considers "that the best food for ponies when turned out is 4 lbs. of split beans mixed with plenty of old hay cut up into chaff, divided into two feeds, to be given morning and evening, and about 10 lbs. of hay in the middle of the day. My ponies thrive better on this allowance of beans than on double the amount of oats." All the ponies should get three feeds of corn daily (early in the morning, at noon, and at night), from about 1st November. "Feeding is of more importance than shelter. Even when open sheds exist in the fields, ponies will not as a rule use them. Consequently, these buildings are not of much advantage, unless the ponies are shut up in them at night. It is a curious fact that even in the coldest and roughest nights in mid-winter, the majority of ponies seem to prefer lying out under a hedge or tree, even in the snow, to using the most comfortable shelter provided for them " (Miller). An ample supply of water should of course « be given.
