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 favorable 

 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 ;
