FERTILIZER INSPECTION.

The law regulating- the sale of commercial fertilizers in this 

 State calls for two bulletins each year. The first of these 

 contains the analyses of the samples received from the manu- 

 facturer, guaranteed to represent, within reasonable limits, the 

 goods to be placed upon the market later. The second bulletin 

 contains the analyses of the samples collected in the open market 

 by a representative of the Station. 



The analyses of the manufacturer's samples for this year were 

 published early in March. The present bulletin contains the 

 analyses of the Station samples and of such of the manufac- 

 turer's samples as were received after Bulletin 50 was issued. 



The figures which are given as the percentages of valuable 

 ingredients guaranteed by the manufacturers are the minimum 

 percentages of the guarantee. If, for instance, the guarantee is 

 2 to 3 per cent of nitrogen, it is evident that the dealer cannot 

 be held to have agreed to furnish more than 2 per cent and so 

 this percentage is taken as actual guarantee. The figures under 

 the head of "found" are those showing the actual composition of 

 the samples. 



A comparison of the results of the analyses of the samples col- 

 lected by the Station with the percentages guaranteed by the 

 manufacturers shows, that, while as a rule the fertilizers sold in 

 the State are up to guarantee, in some instances the particular 

 lots of fertilizers sampled are not as good as they should be. 

 The comparisons indicate that many of the manufacturers do not 

 intend to do much more than make good the minimum guarantee 

 and it is not surprising that this results in some of the goods fall- 

 ing below the guarantee in one or more ingredients. As this seems
