HocforNa, und«r Professor Hunt's direction f Cornell 

 247, 1&0-192), approached the probitira in a different manner. 

 Sodium nitrate was applied to the end of a plat (468) 

 Table XII, where millet was growing in corn. This part of 

 the plat is deeignated as 462 N, aft*&r the fertilieer was 

 applied. The growth on the whole plat was ssrlouely 

 cheeked as compared with the check plate where corn was 

 growing alone and receiving cultivation. When the aodium 

 nitrate was applied, the moisture in this plat, fudging from 

 the averages of soil moisture, was not low enough to cause the 

 laek of growth, but the N0_ in the soil was running very 

 low. "Twice the amount of nitrate of soda necessary to 

 supply 86 parte per mixlion of dry soil to 2,000,000 of soil 

 or to a depth of 8 inches was applied to 35 hills of the 

 maiae plat, known as 402 N.on July 6, 14, 21, and 27, or 

 four applications in all. At the end of the first week or 

 on July 14, both the maise and the millet were much greener 

 than the rel|^ of the plat (462) not so treated, but it 

 could not be s&id with certainty that the growth was greater 

 although it seemed a shade longer j on July 18, however, 

 the hills were distinetly larger than the other hills of 

 the millet plat, and as green as the plants on the eulti- 

 vated plat."
