shoots are soon killed from lack of necessary light. (Figs. 4 and 5.) 

 The branches which are first to appear and which are first to be 

 killed are those closest to the ground. It is therefore very important 

 when cutting this crop to cut the plants high enough from the 



FIG. 4. Sweet-clover plants, showing the direct relation that exists between the thick- 

 ness of stand, the time of cutting, and the height at which the stubble must be cut 

 if a second crop is to be expected. The plant at the left was cut 10 days later than 

 the plant at the right. Note the height at which it was necessary to cut this plant 

 so that a second crop would develop and also the scars on the stubble where young 

 shoots had started earlier and were killed from lack of sunlight. When the stand is 

 thin the young shoots will survive, as they did on the plant at the right, even though 

 the field is cut at a later date.

 branches to produce a second crop.
