in spring-time, preferably when the crop is about 

 6" high. 



After cultivation, the whole crop can be chain 

 harrowed and rolled, and when the crop is about a 

 foot high the inter-crop may be sown. This latter 

 point is very important. If the inter-crop in a corn 

 crop is sown before the " nurse crop " is advanced 

 in growth to the stage mentioned, there is a danger 

 that the inter-crop may grow too vigorously and 

 render the cutting of the corn crop very difficult t® 

 effect with a corn binder — that is, the butts of the 

 sheaves may contain a portion of green material 

 which prevents the corn passing easily through the 

 binder canvasses, and also retard the drying of the 

 sheaves when in the stooks. 



If the corn has been allowed to get advanced in 

 growth before the inter-crop is sown, then the former 

 just permits the latter to get a root hold, but keeps 

 its further growth in subjection, exactly as is the case 

 when grass seeds are sown with a corn crop. In a 

 moist growing season, the inter-crop, of necessity, 

 will get advanced in growth by the time the corn is 

 ready for harvesting. Under these conditions the 

 corn must be cut with a high stubble. 



Generally the type of inter-crop sown with a corn 

 crop will be the mixture of tares previously given. 

 After the corn has been removed the tares should be 

 grazed down, and the grubber run between the rows 

 of tares. This has the effect of rooting out the corn 

 stubble, thereby forming a soil mulch and refreshing 

 the tare crop, and so hastening growth. 



In the following spring the second cultivation of 

 the tare crop must be carried out in precisely the same 

 manner as with the corn. In this case, the tares 

 should be allowed, no matter how late tha season, to 

 get sufficiently advanced to allow of grazing down
