have recently shown a small increase in cost, the former being quoted on 

 Sept. 26 $1.69 and the latter 54 cents higher per ton than for the six months 

 ending March 1, 1932. 



High grade sulfate of potash has shown a decline in price of 75 cents per 

 ton, this being the only change recorded for this element. 



From the above, it would seem that no material increase in the cost of 

 mixed fertilizers for 1933 can be anticipated, and it is not unlikely that some-

The following fertilizer trade values are based on average wholesale quota- 

 tions taken from trade journals for six months ending March 1, 1932, to 

 which 20 per cent has been added for overhead, proper allowance having also 

 been made for bags, labor, and freight when appropriate.
