and labeled with the Station number corresponding to that on the — i iM 
index book. The cans, each bearing only a simple number for identi- — 
fication, are then placed in the hands of the assistant chemists for 
analysis. The analysts who carry out the details of anaylsis know 
absolutely nothing as to what brand of fertilizer they have in hand, 
The analytical methods used are strictly those adopted by the Asso- 
ciation of Agricultural Chemists. Every determination is duplicated 
once at least. . 
The results of analysis and other data are‘arranged by the chemist 
and are finally inspected by the director before publication. 
In cases where several duplicates of the same brand have been 
sampled, several of these samples, taken in different localities of 
the State, are selected, and one hundred grams taken from the well 
mixed contents of each can. These several portions thus taken are 
thoroughly mixed, and then the sample for analysis is taken from the 
mixture thus prepared. 
If the results of the analysis of the first sample correspond to the © 
guarantee, then no other samples of that brand will, as a rule, be 
analyzed during the present season. If, however, in the first case, 
the analysis gives results lower than the guarantee, then numerous © 
other individual samples will be analyzed. It is believed that this — 
method will do justice to all parties concerned more surely and 
satisfactorily than any other method. 
Only samples collected by duly appointed agents of the Station 
will be analyzed and reported upon officially. 
8. GUARANTEES. 
In every case, the Station’s analyses of brands are compared with 
the manufacturer’s guarantee. The data are so arranged in the 
tables of analytical results that comparison can readily be made by 
anyone. 
9. Graturrous ANALysIs OF CoMMERCIAL FERTILIZERS FOR F'ARMERS, 
The Station will continue, as in the past, to make analyses of com- 
mercial fertilizers for farmers, without charge, on the following 
conditions: (1.) That the samples are taken by consumers from 
stock of present season, and in accordance with the Station instruc- 
tions for sampling. (2.) That the samples are fully described on the 
Station “Form for Description of Sample,” or otherwise, as may be 
sees fit.
