POINTS FOR CONSIDERATION AS TO RELATION OF 

 PRICES OF FARM PRODUCTS TO NITRATE OF SODA 

 PRICES. 



From the farmer's point of view, when a reduction in 

 the price of cotton and produce happens, it is to be 

 deplored, but in such a case it should be considered 

 whether abstention from the use of Nitrate is a wise way 

 of meeting the situation. The utility of a fertilizer obvi- 

 ously depends upon its productivity, which is not affected 

 by its price, and an increase in the latter justifies aban- 

 donment of the fertilizer only when its jjroductivity ceases 

 to be profitable. The profit to be reasonably expected 

 from the use of Nitrate of Soda is not so materially 

 interfered with by any ordinary rise in its price as to 

 economically justify any substantial reduction in its con- 

 sumption.
