The are not quotations in any sense of the word, and all the 

 Cultivation of fig ures of the table refer only to one grade of Nitrate of 



Soda, namely: that containing 15.65 per cent, of Nitrogen, 



28 equivalent to 19.00 per cent, of ammonia. It is prepared 



merely in order that purchasers may compare the price of 

 Nitrate of Soda, which is always quoted by the hundred 

 pounds, with other ammoniates, which are quoted by 

 the ton unit. In the first column, therefore, are given the 

 prices per hundred weight of Nitrate of Soda ; in the second 

 column, the equivalent price of the ammonia per ton unit; 

 in the third column, the corresponding prices per ton; in the 

 fourth column, the cost of the contained ammonia per 

 pound, a figure which is always discussed, but almost never 

 explained in Station Bulletins, and in the fifth column 

 are given the corresponding prices of the cost of the Nitro- 

 gen per pound, a figure also much discussed, but not always 

 explained in Bulletins. The important figures to remember 

 are the price per hundred weight, the price per ton and the 

 equivalent price of the ammonia in the Nitrate per ton unit. 

 The table is prepared to cover fluctuations in price running 

 from two dollars per hundred, to three dollars per hundred; 

 or from forty dollars to sixty dollars per ton.
