Beet digger. When fed to cattle, mangels are usually "pulped" or grated to irregular-shaped pieces about three- fourths of an inch in size. British feeders frequently mix the pulped roots with chaffed hay or straw and let them stand twelve hours before feeding. For sheep they are cut into finger pieces, or else sliced. Enemies. _ Mangels have few troubles, and should any occur which cannot be controlled by good tillage and good rotation, it will be better to abandon the crop. The diseases are the same as those of the sugar- beet [which see]. Parsnip. Pastinoca saliva, Linn. Umbelliferce. This plant is biennial, and is grown for its thick- ened stem and root, which is used for human food and for stock-feeding. The parsnip was doubtless known to the Greeks and Romans, and it has figured in most of the herb- als written since the sixteenth century, showing that it was well known and was used as food. It was disseminated in the West Indies by 1564, was cultivated in Virginia as early as 1609, and was grown in other colonies later in the same century. The Indians of western New York cultivated it in the eighteenth century. Wherever it has grown readily it has tended to escape from cultivation and become wild. Seedlings from wild plants will assume the characteristics of the cultivated forms under favor- able conditions. The plant is generally considered to be a native of
