360 BOAED OF AGRICULTUEE. 



The fertilizer is sold to farmers at $50 per ton. A few 

 additional percentages of potassa would be a judicious change. 

 The fertilizer, however, is fully worth the price asked for it 

 in its present condition. 



Messrs. C. A. North & Co., of Boston, manufacture a simi- 

 lar animal fertilizer at their hog-slaughtering establishment. 



Their mode of operation resembles quite closely that pur- 

 aued at the Brighton abattoir. The bones, the meat scraps 

 and the blood obtained from one thousand hogs per day can 

 be treated in their apparatus. Their daily produce of fertil- 

 izer is stated to be three tons. 



Laro;e establishments of a similar character are in construe- 

 tion at New York City and at Jersey City. It is a fact of con- 

 gratulation to the farming interest of the Atlantic States, 

 that, with the increase of the meat-packing business in their 

 commercial centres, improved modes of converting the animal 

 refuse material obtained, in an economical and rational way 

 into valuable fertilizers, find a rapid introduction. 



Meat, blood and bones contain the most essential substances 

 of the food consumed ; their influence regarding the repro- 

 duction of the staple crops of the country cannot be second to 

 any fertilizer in our market, provided a suitable mechanical 

 condition favors their speedy disintegration. It matters very 

 little which of our domesticated animals furnish the material 



cattle, sheep or hogs. The water contained in the meat of 



these animals varies from 72 to 79.3 per cent. 



Fresh meat from cattle contains 3.29 per cent, of nitrogen.

which, on an average, amounts to 3.35 per cent.

In dry meat, the nitrogen varies from 14.30 to 15.72 per 

 cent., provided the fat has been abstracted. The blood of 

 these animals amounts to about one-tenth of the weight of the 

 entire body, and is in all of them of a very similar composi- 

 tion. It contains, on an average, 78 parts of water and 22 

 parts of dry substance.
