Prairillon

“As night had closed in, we found some difficulty in choosing a camping-place: at length we pitched upon a prairillon under the lee of a hill, where we had bunch-grass and fuel, but no water. The wind blew sternly through the livelong night, and those who suffered from cramps in cold feet had little to do with the ‘sweet restorer, balmy sleep.'”
