EXPERIMENT II. 
Another series of experiments with millet was made with this same 
type of soil — namely, No. 2 — the results of which are given in Table IV. 
Fertilizers were added hi the same amounts as in the previous series, 
and the soil was otherwise given similar treatment. This was deemed 
necessary to verify some of the results obtained in the first series. 
After the second crop of millet, a complete fertilizer was added before 
the planting of the third crop. (See Pis. Ill and IV.)
