On this day, as they rode along, they came on some thing that interested them both. In a grassy hollow at the head of a dry coulee they saw a little brown mustang mare and a brand new colt. The colt was an awkward-looking scamp as he stood with his trem bling legs braced wide apart, catching his breath after the effort of getting up. His body was close knit and compact, and his back was strong and flat, but his legs were so long and slender he appeared to be walking on stilts.
