■ Guaranteed also to contain .75 per cent potash. 2 Two analyses made. 



Brands showing a Commercial Shortage of $I or over per Ton. 



1 This product was sold on a unit basis and guaranteed 6.12 per cent ammonia and 15.79 per cent phosphoric 

 acid (.which is 43ractically a 6-14 grade), the unit price being $3.80 for ammonia and 10 cents for bone phosphate 

 of lime. The commercial shortage was $1.24 and the rebate due for deficiency was $2.50 per ton. This sample, 

 collected at Bolton, had a commercial valuation of $42.68 per ton. Although the company's analysis showed' 

 this grade of tankage to run 6.12 per cent ammonia and 15.79 per cent phosphoric acid, yet the difference in com- 

 position found by the station analysis, quite likely made on a smaller tonnage than was the company's test, in 

 this particular case emphasizes the importance of a control analysis in ca.se of products bought on the unit ba.sis. 



2 Further tests revealed the presence of 5.88 per cent of potash, 1.04 per cent of nitrogen in'^form of nitrates and 

 ammoniates, and 7.04 per cent of available phosphoric acid. The explanation of the Rogers & Hubbard Co. with 

 reference to this sample was that the regular supply of stencilled bags for Hubbard's Seeding Down Fertilizer 

 became exhausted and a few plain bags were filled with this mixture and piled near the stock of ground bone; 

 through a mistake a few bags of this mixture were probably tagged as Strictly Pure Fine Bone. Less than one 

 and one-half tons were involved and the commercial shortage was adjusted by suitable rebates.
