7^ Experiments on Manuresi 



quantities. Ten loads of this manure, on poor land, will 

 produce orc'inarily twenty five bufliels of wheat, which exceeds 

 by five dollars the expence of the manure, and the five dollars 

 pays for the expence of labour in raifing the crop. The land 

 is then left ina ftate for yielding a crop of hay of between two 

 and one 'and an half toris per acre, which it will continue to 

 do for a great number of years. In fhort, no manure has 

 been found, as' yet, to continue fo long in the ground as 

 afiies. What will be the refult of the firft manure in that 

 refpeft is uncertain. 



The fcarcity of aflies will be in proportion to the fcarcity of 

 wood on the fea coafts, where it anfwers beft for a manure, and 

 in a few years cannot probably be procured in any confiderable 

 quantities. I would propofe to the fociety to order an experi- 

 ment to be made as a fubflitute for this article, and which will 

 be of the fame kind of manure ; which is, to buy in New- York 

 a barrel of the falts of lye, which it is faid will coft fifty fliillings ; 

 let a bed of earth be made in the field where you propofe to 

 ufe the manure ; diflblve this barrel of falts in any quantity of 

 water which fliall be thought fufficient to impregnate five loads- 

 of dirt, and with a watering pot fprinkle your bed of earth ; 

 then put on more earth, and water the fame with the diflblved- 

 falts, and fo on, till the whole five loads partake of the falts in 

 as equal a manner as may be ; perhaps after fome days it will 

 be beft to remove the whole, by (hovelling the fame into another 

 heap for the purpofe of mixing it more equally ; then cart the
