tained during the season. The end of the second year the plants may be ploughed down, as the third year 
they will run to seed, and yield but small leaves. The leaves are pressed, and the juice treated as in making 
mdigo (see Indigofera) : but such is the cheapness of the latter article, that no British farmer can afford to raise 
any sort of substitute. 
1431. Myagrum. An ancient plant, so named from its properties of catching flies, which the modern plant 
does not possess ; fx^vtoe,, a fly, cty^tx,, capture. 
1432. Brassica. The etymology of this word has been explained with great learning and ingenuity by Vossius, 
Ray, Dalechamp, and others. It comes, however, from the Celtic bresic, which signifies a cabbage. This 
genus affords the well known pot herbs and roots, and also the oil plant rape, extensively cultivated in agri- 
culture. There is scarcely an instance in the vegetable kingdom of a plant that produces varieties so different 
m appearance and quahties as the B. oleracea ; comparing the original plant as it is found on our shores, with 
wavy sea-green leaves, no appearance of a head, and flowering Mke wild mustard or charlock, with the red 
cabbage or cauliflower, the difference is astonishing. A new arrangement of the cultivated species of Brassica 
has been made by Professor Decandolle {Hort. Trans, vol. 1., and in his Res. Ves.), whose varieties, or races of 
B. oleracea, are stated above. 
The colxa of the Dutch he makes a distinct species (B. campestris), and also the turnip (B. rapa) : the rape 
(B. napus), and the summer rape of the Germans (B. prsecox). 
In Hungary, in the territory of Alba, the B. elongata is cultivated for its oil, for which purpose it is said to 
be better adapted than any other species. 
The culture of all the Brassica tribe is so universally known that it would he a waste of space in a work of 
this sort to enlarge on it. They all prefer a loamy soil, well enriched with manure ; and manures of the 
strongest kind, as nightsoil, offals from the shambles, blood, &c. are not found too powerful for common cabbage 
or cauliflower. The turnip prefers a lighter soil than the cabbage tribe, but it must be well manured, and if the
