ress of modern agriculture, being the most nutritious 

 form of Nitrogenous or ammoniate plant food. While 

 the action of micro-organisms with . . 



certain crops (legumes) combines and ^Modern* 1 

 makes effective use of the inert Nitrogen Agriculture, 

 of the atmosphere, such action is far 

 too slow and uncertain for all the requirements of 

 modern agriculture, for it is not available for use for a 

 whole year or even longer. The rapid exhaustion of 

 combined Nitrogen has several times been noticed by 

 eminent scientific men, with reference to food famine, 

 because of a lack of the needful Nitrogenous plant food. 

 It has been estimated under the present 

 methods of cropping the rich lands of 

 our Western States, that tor every 

 pound of Nitrogen actually used to 

 make a wheat crop, four to five pounds are utterly 

 wasted. In other words, our pioneer agriculture has 

 proceeded as though fertility capital could be drawn 

 upon forever. 



This injudicious waste is already reducing the 

 yield of many of the best lands, rendering the use of at 

 least a small application per acre of Nitrate both profit- 

 able and necessary. The agricultural 

 value of Nitrate of Soda has had the Eminent Scien- 



attention of the foremost agricultural sts ^L w A rld

 in Spain; and Drs. Voorhees, Brooks, Duggar, Ross, 

 Patterson, Hilgard and Garcia in America. The re- 

 sults obtained by these officials may be summarized 

 as follows: 



1. Nitrate of Soda acts very beneficially and with 

 great certainty upon all straw-growing plants. 



2. It is of special value for forcing the rapid de- 

 velopment and early maturity of most garden crops. 



3. It is of great importance in the production of
