or an excess of 13.4 per cent. of nitrogen, of 10.6 per cent. of avail- 
able phosphoric acid, and of 10.7 per cent. of potash over the 
minimum amount guaranteed; while the maximum amounts guar- 
anteed were 19.6 per cent. of nitrogen, 13.5 per cent. of available 
phosphoric acid and 18.0 per cent. of potash, greater than the . 
actual amounts of each of these.constituents found to be present. 
For the details of this branch of the work of the Station refer- 
ence is made to the report of the Chemist and the several bulletins 
giving results of analysis. 
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 practic- 
ally 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 containing 
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 fer- 
tilizing materials, and analyses be made of them to determine 
‘whether these products are found up to their guaranteed composi- 
tion within the limits prescribed by law. 
The amount of analytical work involved in carrying out the 
provisions of this law is so great that it is practically impossible 
to do any work which is unofficial and of the general nature of 
private work, as analyses of individual. samples of fertilizers, of
