246 SOUTHERN FIELD CHOPS 



(3) If a field of any class or variety of sorghum can be in- 

 spected, make record of the following : 



(a) The apparent impurity, or percentage of plants which 

 seem to belong in a different class or variety ; 



(5) Effects on the size of heads and size of stalk due to wide 

 or close spacing of plants. 



(4) If a field of kafir or milo can be inspected, note whether 

 there is uniformity in the height of plants and time of ripening. If 

 not, does this diversity interfere with the local method of harvest- 

 ing the seed ? 



(5) If fields of saccharine sorghum are available, cut short 

 sections of the same row when the plants are at different heights, 

 or stages of maturity ; record the weights and condition when 

 cut, and a month or two after each cutting, note the effects of 

 cutting at different stages on the height of the second growth.
