Dried Blood and Takkagb. 



Four analyses of these materials have been made for private 

 parties, and the results are here given with the other analyses 

 made for purchasers. 736. Dried Blood, made by Sperry & 

 Barnes, New Haven ; sent by J. J. Webb, Hamden. 768. Tank- 

 age, made by Strong, Barnes, Hart & Co., New Haven ; sent by 

 J. M. Hubbard, Middletown. 702, 703 and 704 are samples of 

 comparatively pure dried blood containing very little bone. 

 " Tankao-e " is a mixture of blood and offal of various sorts with 

 fragments of bone. It contains less nitrogen, more phosphoric 

 acid and usually more moisture than the pure dried blood. 736, 

 768 and 784 are all articles of this class.

Estimated value per ton, $44.61 41.83 

 Cost per ton, $35.00 35.00 



Allowing 6 cents per pound for the phosphoric acid in 736 and 

 768, the nitrogen costs 18 cents in one and 19 in the other. No 

 other fertilizers examined this year furnish nitrogen in so cheap 

 and readily assimilable a form.
