28 THE SEED-GROWER. 
For a seed-crop, seed is sown in northern States in 
August, the plant not being allowed to become fully 
developed. In latitudes where the climate is not too 
rigorous, plants may be left in the field undisturbed 
over winter, but where it is too severe as in the northern 
Atlantic States, they should be dug up entire and stored 
either in a trench or in a sheltered place, covered lightly 
with coarse litter, or in a cellar, the plants being packed 
closely with soil. In spring they should be set out two 
feet apart, in rows three feet apart. 
Cultivation, harvesting, threshing, cleaning, etc., are 
similar to what has been given in preceding pages for 
borecole. 
Market.—The quantity of Brussels sprouts seed con- 
sumed in the United States is upwards of 10,000 pounds 
annually. The greater portion of this is imported from 
Europe, from whence it is laid down in New York at 
about fifty cents per pound; the remainder is raised 
mostly on Long Island, New York, and is equal to the 
imported in quality. A yield of seed in a favcrable 
season is from 400 to 500 pounds per acre. 
CABBAGE. 
While this vegetable thrives best in a cool, moist 
atmosphere, or where the nights are uniformly cool, it 
succeeds well in almost any section of the United States. 
It will grow in any soil from a light sandy to a heavy 
loam, but is a gross feeder and requires heavy manur- 
ing, either well-rotted stable manure or a commercial 
fertilizer made up to contain about seven parts of nitro- 
gen to eight of available phosphoric acid and about six 
of potash. The soil should be well harrowed and made 
into fine tilth. 
For the seed bed, the soil should not be too rich;
