Cost of fertilizers Applied per Acre. 



In order that the experimenters and other farmers may bet- 

 ter understand the inquiry made upon the different plots, the 

 cost of the different materials used is given in the statement 

 which follows. The calculations are made upon the cost laid 

 down at Auburn. The local freights upon the packages re- 

 shipped to the depots of the experimenters would produce a 

 false impression, since the average local rate of freight charged 

 upon the amount sent to each experimenter from Auburn to 

 their depots exceeds five dollars per ton. Shipped in quantity, 

 the freight to the various depots of the experimenters would 

 average little more than that from the factories to Auburn. 

 Again, in estimating profits resulting from the use of the dif- 

 ferent fertilizers, it will be more convenient to have a common 

 standard of comparison.
