There is a strong likelihood that the tiny seed of this very plant is identical with the Mustard seed of the Saviour's parable, in which He likened it unto the Kingdom of Heaven. The Mustard was extensively cultivated in Palestine for fodder, and from Asia and Europe it was introduced into our country, where it has spread from one end of it to the other. Surely, from its persistent spreading nature, the seed is symbolic of His divine command: "Go ye into all the world and preach the gospel to every creature." The very small, dark brown seed is a most important commercial product. It furnishes one of the most popular table condiments, as well as one of the best known household applications for common physical ailments. The use of hot Mustard foot-baths for colds and chills, and of the homely, blistering Mustard plaster for the relief of every pain is only too well known in every family. The oil of Mustard, made from the seeds, is intensely pungent, and is used for making liniments and soap. When used as fodder, the plant is harvested before the seeds mature. The Black Mustard is common throughout our country from June to November, in fields, roadsides, and waste places. Its presence is a familiar one about abandoned farm buildings and weed-grown foundations, marking the ravages and desolation caused by fire and decay. It is conspicuously at home in the vicinity of public ash dumps and in neglected gardens. While it is extensively cultivated in Europe, it is looked upon by farmers in this country as a most prolific and troublesome pest. It grows erect from two to seven feet high, and branches widely. The lower leaves are slender-stemmed and deeply cut into two or three pairs of irregular parts, and balanced on the end with a single large lobe. The edges are variously toothed. The shorter-stemmed upper leaves are lance-shaped, and often smooth-edged. The leaves are loose-textured, and on the underside they are hairy. They are set on the stalk at the base of the branches. The flower has four bright yellow petals, arranged like an oblong cross -the cross sign "X" of multiplication, which is one of the chief characteristics of all of the flowers of the Mustard family, and which the Latin name, Cruci-ferae, signifies. The flowers are less than half an inch broad. The delicate, rounded petals are narrowed at the base, and are spread toward the apex. The greenish yellow calyx has four narrow divisions. The green pistil is tipped with yellow, and there are four yellow stamens. The flowers are gathered toward the end of the stalk on short stems, forming a loose, golden sceptre. They are rapidly succeeded by short, narrow, flattened, four-angled seed pods, which are pressed toward the stem, and are tipped with a short, slender beak. Brassia is the Latin name for Cabbage.
