Numerous names have been suggested by their fancied resemblance to the feet, hoofs, and tails of animals and birds; as, for instance, colt's-foot, crow-foot, bird's-foot trefoil, horse-shoe vetch, bull-foot, and the vervain, nicknamed frog's-foot.

Many curious names have resulted from the prefix pig, as in Sussex, where the bird's-foot trefoil is known as pig's-pettitoes; and in Devonshire the fruit of the dog-rose is pig's-noses.

The spring was by this time broadening into the loveliest of all times on the prairies (when the weather is fine), the days of the full blowth of the upland bird's-foot violets.

BIRD'S-FOOT-LOTUS.There are several varieties of this plant; one growing on very dry chalky soils, and which in such places helps to make a good turf, and is much relished by cattle.
