Millet was so'\\ti in the maize and in the middles of certain plats, as in 

 1907, but was not sown on different dates. A miscellaneous assortment 

 of weed seeds was sot\ti on the ends and on the middles of other plats. 

 In Table 12 is shown the nitrate content of the soil under maize and 

 millet mixed, under maize and weeds mixed, under millet alone, and under 

 weeds alone:

The yields of maize were extremely poor on these plats. This is an 

 interesting condition, as it gives in some cases about the same yield of 

 maize and millet combined as of millet alone, and the same yield of maize 

 and weeds combined as of weeds alone. This is brought out in Table 13:
