vetch (V. dasycarpa) of the Mediterranean region, the Carob tree or St. John's 

 bread {Ceratonia sili-qua) is a small tree of the Mediterranean region, the 

 pods of which contain much mucilage of a sweet nature from which syrup 

 was made, and is supposed to be the locust which John the Baptist lived upon in 

 the Wilderness and is used as food; and cattle also relish it. Manna (Alhagi 

 mauroruni) is a dwarfed, thorn)', shrubby plant which produces a kind of 

 manna. The locust trees of the West Indies, or Courabaril {Hymenaea Cour-

 in a white spongy mass. The Zamang (Pithecolobium Saman) is a large 

 tree of Venezuela which produces thick, flat pods, containing a sweet pulp 

 commonly used by cattle and horses for food but which are liable to cause 

 internal disorder. The honey locust of eastern North America {Gleditschia

 {Glymnocladus dioica) is native to the Mississippi Valley and it produces a 

 broad, tough pod which contains large, hard seeds. The pod contains a sweetish,

 is durable. The seed of hairy vetch (Vicia hirsuta) is a common impurity 

 in grain seed. The plant is used for forage. The seeds of Castanospermum 

 OTistralis are used in New South Wales in the production of starch. The

Medicinal Plants. Of the medicinal plants, in this family, the most important 

 only will be mentioned here. The broom (Cytisus scoparius), native to Europe, 

 is used as a diuretic and purgative. Fenugreek (Trigonella Foenum-graecum) 

 was formerly used in medicine, but the powdered seeds are now used as an in- 

 gredient of curry powder and also in the preparation of stock foods; they 

 have a characteristic odor and bitter taste. Licorice root (Glycyrrhiza glabra 

 and var. glandulifera (Russian), native to the warmer regions of Europe and 

 extending eastward into Central Asia, is made into extract of licorice which 

 is used to cover the flavor of nauseous medicines and contains the glucoside
