The last of the roundups was held in Routt County, Colorado, several years ago, so far as the writer knows, and it had only to do with shifting cattle from the summer to the winter range.
After the calf round-up came the beef round-up, the cowman's final harvest.

This began in July or August.

Only the mature or fatted animals were cut out from the herd.

This "beef cut" was held apart and driven on ahead from place to place as the round-up progressed.

It was then driven in by easy stages to the shipping point on the railroad, whence the long trainloads of cattle went to the great markets.
In the heyday of the cowboy it was natural that his chief amusements should be those of the outdoor air and those more or less in line with his employment.
