PLANTS OF THE BRASSICA GENUS. 157 



Distribution. This crop is wide in its distri- 

 bution. There is probably no state in our republic 

 and no province in Canada in which it may not be 

 grown, and with considerable success. While it has 

 highest adaptation for cool and moist climates, it 

 will, nevertheless, grow better relatively in warm 

 climates than rape. But in these the enemies of the 

 plant, such as the aphis and the cabbage worm, are 

 much more troublesome than in northern latitudes 

 where the mean summer temperature is lower. Thig 

 crop may be grown in best form in the states of the 

 Union which border upon Canada and in the 

 provinces of Canada which border upon the 

 United States. But excellent crops can be grown 

 under certain conditions in states much further 

 south. In fact, there are but few states in the 

 Union which, in some of their more elevated valleys, 

 do not furnish just the right conditions for grow- 

 ing cabbage. 



Where the crop can be successfully grown as 

 human food, it may also be successfully grown as 

 food for live stock, for the requisite conditions to 

 produce either crop are essentially the same. But it 

 should be carefully observed, that because a cabbage 

 crop has given a financial profit when grown for the 

 human family, it does not follow it will also give a 

 financial profit when grown as food for live stock. 

 Such an assumption would not, of necessity, be cor- 

 rect, since it involves the consideration of relative 

 values of cabbage in the market and of meat and 

 milk produced by the cabbage when fed. 



Soil. Cabbage like all plants of the Brassica 

 genus luxuriate in a fertile soil, and more especially
