_ GRATUITOUS ANALYSIS OF COMMERCIAL FERTILIZERS. 
a New York Srare AGRICULTURAL EXPERIMENT STATION, i. 
~ Geneva, N.Y. . 
To insure justice to manufacturers, dealers and consumers alike, 
thé Station will make gratuitous analyses of commercial fertilizers 
on samples taken by the agents of the Station, or on such others as 
are properly authenticated by the certificate of the person drawing 
the sample and in addition the witness of some competent person. 
The expense of making the analysis and the importance of the pub- 
lished results for good or evil to the manufacturer require that every 
precaution be taken for carrying out the directions given below for 
sampling. 
Directions To BE FoLLowepd IN Samptina CoMMERCIAL FERTILIZERS. 
1. Provide a teacup, some large papers, and for each sample a glass 
if fruit can holding about one quart, that can be tightly closed, all to be

of the fertilizer, or, if there are more than thirty, weigh every tenth © Y bi

tion of sample. 
3. Open the packages that have been weighed and mix well together 
the contents of each down to at least half its depth, emptying out 
_~upon a clean floor, if necessary, and crushing any soft moist lumps 
i unbroken, so that the sample shall exhibit the texture and mechanical 
condition of the fertilizer. 
4, Take out five equal cupfuls from different parts of the mixed 
portion of each package. Pour them, fifteen in all, over one another 
on the paper, intermix again thoroughly, but quickly, to avoid loss or
