The adjutant bird (Leptoptilus dubius) is one of Nature’s little jokes. It is a caricature of a bird, a mixture of gravity and clownishness. Everything about it is calculated to excite mirth—its weird figure, its great beak, its long, thin legs, its conspicuous pouch, its bald head, and every attitude it strikes.

Our standard wheat flour contains only the endosperm and represents practically a 75 per cent. extraction. The remaining 25 per cent. is known in the trade as grain offal or mill-feed, and is used largely as a concentrated food for live stock, being prized in the feeding of dairy cattle.
