The samples were taken by our regular inspector, 

 Fertilizers Air. Jas. T. Howard assisted by Mr. E. C. Hall 

 Collected. and Mr. E. L. Winn. An effort has been made 

 in all cases to get representative samples. At 

 least 10 per cent of the bags found present have been sampled by 

 means of an instrument taking a core the entire length of the bag. 

 In no case have there been less than ten bags of each brand sampled 

 wherever that number has been found in stock. In case of bulky 

 mixed goods which might have a tendency to mechanical separa- 

 tion in transit, a sample has been taken from both sides of the bag 

 so that in case any of the fine, heavier chemicals such as potash 

 salts had sifted through the more bulky portion, the sample taken 

 would be more representative. 



Whenever possible, samples of the same brand have been col- 

 lected in various parts of the state, the object being to sample as 

 large a proportion of the tonnage shipped into the state as possible. 

 In most cases where duplicate samples have been drawn, a com- 

 posite made up of equal weights of the various samples served for 

 the analysis. In some instances several analyses have been made 

 of the same brand ; this has been done at the request of large con- 

 sumers who[^have bought heavy shipments of some special brand. 

 It is difficult to tell how large a per cent of the total tonnage 

 shipped into the state has been sampled. An effort was made at 

 the end of the season of 1910 to ascertain approximately the num- 

 ber of tons sold, but some of the larger manufacturers refused to 

 furnish the data. As complete and extensive a collection as pos-
