later. The second bulletin (45 j contained the results of the 

 analyses of the samples collected in the open market by the 

 officers of the Station, and was published in October. 



A comparison of the percentages guaranteed b}' the manufac- 

 turers' samples and those collected by a Station representative in 

 different parts of the State, shows that, as a rule, the fertilizers 

 sold in the State are well up to the minimum guarantee. In a 

 few instances the particular lots of fertilizers sampled were not 

 quite as good as they should be; there was, however, no case 

 which appeared to be an attempt to defraud. The comparisons 

 indicate that the manufacturers do not intend to do much more 

 than make good the minimum guarantee, and this is all the pur- 

 chaser can safely expect.

 sons of manufacturer's and Station samples vrith the guarantee.
