Alphano Humus Co. — Prepared Alphano Humus, No. 955: nitrogen 

 found, 1.63 per cent, guaranteed, 1.25 per cent; total phosphoric acid found, 

 .59 per cent, guaranteed, .50 per cent; potassium oxide found, .04 per cent, 

 guaranteed, .50 per cent. Upon the receipt of the advanced report of this 

 analysis, the company requested that other samples be drawn and tested for 

 potash as they felt confident that the average of this brand shipped into the 

 State contained the minimum potash guaranteed. Two other samples were 

 therefore secured and both showed serious deficiencies in potash, one testing 

 .07 per cent and the other .08 per cent of actual potash. The explanation 

 given by the company with reference to the shortage in potash shown in all 

 of these samples was that the wood ashes which they were obliged to purchase 

 and use as their potash source must have been leached. They furnished the 

 information that hereafter nothing but potash salts would be used in furnish- 

 ing the potash supplied in their material. 



American Agricultural Chemical Co. — Grass and Oats Fertilizer, No. 879: 

 no nitrogen guaranteed; available phosphoric acid found, 10.84 per cent, 

 guaranteed, 11 per cent; potassium oxide found, 1.77 per cent, guaranteed, 

 2 per cent.

 1.61 per cent, guaranteed, 1.64 per cent; available phosphoric acid found, 

 8.42 per cent, guaranteed, 8 per cent; potassium oxide found, 3.22 per cent,
