But in summer they are at no loss, for besides an abundance of streams and springs, plenty of rain water collects in the pools, by the side of which grass is abundant, and the yak, by no means a dainty feeder, after growing thin during winter, becomes fat again in autumn; this is particularly the case with young bulls and single cows.
