what similar protection from the fertilizer inspection that he 

 had in earlier years when the brands ran far more uniform in 

 their manufacturing formulas than is now possible. 



Because of the physical impossibility of analyzing all of the 

 samples that might be collected and sent to the Experiment Sta- 

 tion or the Department of Agriculture, it is suggested that the 

 moment the consumer receives his fertilizer for 1921 that he 

 take a sample of the goods in accordance with directions which 

 are briefly stated below. 



CONCISE DIRECTIONS FOR SAMPLING FERTILIZERS. 



The sample may be taken by means of a sampling tube that 

 reaches the whole length of the package or as follows : 



Provide a teacup, a large sheet of strong paper, and for 

 each sample a clean and dry pint or quart glass fruit jar fitted 

 with a rubber ring. 



Open at least five full and unbroken packages, and thor- 

 oughly mix the contents of each for a foot in depth; take out 

 three cupfulls from different parts of the mixed portion of each 

 package, pour them over one another upon a paper and inter- 

 mix thoroughly but quickly to avoid loss or gain of moisture; 

 fill the jar from this mixture; seal with wax and attach to the 

 jar some such a statement as follows: 



This jar contains a sample of fertilizer taken by me in the 

 presence of Mr : _ as witness. 



I certify that the sample is from five unopened packages 

 as received by me on (insert date) and that to the best of my 

 knowledge and belief the sample fairly represents the stock 

 from which it was taken; and said stock was properly housed 

 and in good condition. 



The following is an exact copy of the printing upon or 

 attached to the package: (This should give: the name of the 

 goods ; the name of the maker ; the kind of package, whether 

 barrel or bag; the weight, and a copy of the guaranteed analyses 

 showing the percentage of nitrogen, available phosphoric acid 

 and potash.)
