very briefly some of their good and bad characteristics, taking 

 them in the order mentioned in the table. 



Buckwheat. — This is desirable because it will grow on almost 

 any soil, leaves the land in better physical condition than perhaps 

 any other crop, furnishes a large amount of humus, is reasonably 

 clieap, and starts so quickly after sowing that it will smother 

 out many annual weeds. This last point is particularly im- 

 portant where one has witch grass to contend with. On the other 

 liand buckwheat furnishes no nitrogen, makes rather a poor 

 cover, and is killed by the first frost. All things considered the 

 orchardist should class buckwheat as among the best three or four 

 cover crops and one which it is difficult to do without (Fig. 45). 



Cow Peas. — These are rather a southern crop and are not as 

 good as several other crops when one gets north of Connecticut. 

 In their own section, however, they are famous as soil improvers. 

 They are sown in July and are killed by fall frost. 



Cow-horn and Purple-top Turnips, — The great advantage of 

 these plants is cheapness, which certainly appeals to a man when 

 he has fifty acres or more of orchard to cover. They also fur- 

 nish an immense amount of humus, make a fairly good cover, 

 and with the purple tops at least one may pull out and sell 

 enough of tlie best turnips to far more than pay all the expense 

 of the crop and still leave plenty on the ground for a cover.
