ostriches were allowed to bring forth in their own sweet way. Of recent years, however, incubation on the most progressive farms has been done by artificial means. The eggs, each weighing between three and four pounds, and of sufficient size to afford a meal for six hungry men, are turned in the incubators twice a day until at the end of six weeks the young chicks are hatched. The PanAmerican farm alone has incubation facilities for 1,800 eggs—a sizable "clutch" indeed—and could hatch 7,000 or 8,000 birds a year.

After the chicks are released from the shells they receive the fostering care of experienced ostrich, men until they are large enough to fend for themselves. A prominent Arizona farmer explained that they "require as much attention as babes." Men unfold their cots in the fields and spend the nights with the
