410 [Assembly 



The superiority of compost Ihus prepared by the fixation of nitro- 

 gen in animal manure in preference to mf-thods used in its prepara- 

 tion by others, namely, the admixture of charcoal, lime, &c , adding 

 theri'hy to the natural constituents, in parts, (while at the same time 

 they chrmge the effects of nature,) is fully proved by the considera- 

 tion of the antecedent remarks. The question of economy for the 

 practical agriculturist is, therefore, alone to be considered. The 

 strength of human manure is computed to be that of 1 to 6 of ordi- 

 nary manure ; the time and labor of mixing this fluid with night 

 soil would not exceed half an hour in preparing, ready for use, one 

 ton ; the cost of the fluid would be about |2 a ton, easily transpor- 

 ted. 



Mr. Alanson Nash said that he viewed the communication made 

 by Dr. Boyd to be a highly important one, as if the facts stated in 

 it were true, and he had no reason to doubt their truth, our emi- 

 grant ships would by the use of this Disinfecting Fluid be rendered 

 healthy and thousands of valuable lives would be yearly saved, which 

 are now lost by ship fevers and other diseases generated on voyages 

 at sea. 



He also regarded the communication of Mr. Pell as valuable, es- 

 pecially that part of it which related to memoirs of the Sewers. 



He had read recently a London paper which contained a commu- 

 nication upon the waste of street u.anure in the city of London by 

 the sewers which emptied into the Thames. 



This writer declared that the sewers of London constantly carried 

 into the river *' legs of mutton and loaves of bread," and regretted 

 that this wastage of manure could not be prevented. 



Mr. N. further remarked that the sewers of New-York carried off 

 daily a great amount of manure into the rivers which partially sur- 

 round the city, but which might be saved at little expense. 



Ci.sterns should be put down at the mouths of the sewers or where 

 they discharge themselves into the rivers, these would collect all the 

 sediu)ent from the sewers, which would be a fertilizing manure for 

 gardens and farms. 



Mr. N. remarked that he did not fully agree with all the proposi- 

 tions of Mr. Pell on the subject of stabling milch cows, though he 

 had no doubt that a great amount of manure was lost by pasturage.
