‘a ectively would have obtained for $4, 000,000 a value in Ones 
_ phosphoric acid and potash as follows: 

In spring.... 132,670 tons at $22.41 equals..... $2,973,134 0 
Simtel... <s 145,188 tons.at 18.91 equals..... 2,744,559 58 
Difference.. 12,468 | $228,575 ee 


In the spring, therefore, although getting 12,468 tons less ‘hack 
they could have bought at fall prices they would have obtained 
an increased value in fertilizing constituents of $228,575.12, an 
average saving of 5.7 per cent, or in other words, while the. 
average cost of these fertilizers in the fall was 91 per cent. 
of their cost in the spring, the average value of the fall fer- 
tilizers was but 84 per cent of the value in the spring; for by 
consulting the table given it will be seen that the average nitro- 
gen in the fall fertilizers was but 62 per cent of the average 
in the spring, and the average potash was but 58 per cent of the 
amount present in the spring, while there was an average of 10. 
per cent more available phosphoric acid present in the fall than 
was present in the spring, the ratio being as 100 for spring to, 
110 for fall. 
_ Acareful study of these matters deserves to be made by the. 
prudent farmer who finds it necessary to increase his home sup- 
ply of manure by means of these commercial fertilizers. 
It appears that it has been the custom of many dealers, 
especially of those selling ashes, to make sales upon prices subject, 
to the analysis of the Station, and it is obvious that it is practi- 
cally impossible for the Station to undertake such work, nor is it, 
contemplated by the law that work of such character should be. 
done at the expense of the State. All fertilizers sold or offered 
for sale within the State at a price of ten dollars or more per ton 
must be sold upon a guaranteed analysis, and the packages con- 
taining such products must have the guaranteed analysis plainly 
printed upon such packages, but it is not required that these, 
analyses are to be made at the expense of the State, the law 
requiring only that samples shall, so far as is practicable, be 
taken of such fertilizing materials, and analysis be made of them. 
to determine whether. these products are up to their guaranteed. 
composition within the limits prescribed by law.
