" The supen^hosphate of lime was made on purpose for these 

 experiment?, and wa.-^ a pure mi:ieral manure of superior quality, 

 made from calcined bones ; it cost about 21 ci nts per jwund. The 

 sulphate of ammonia was a good, commercial article, obtained 

 from London, at a cost of about seven cents per pound. The ashes 

 w.re made from beech and hard maple (Acer siccharinum) wood, 

 and were sifted through a fine sieve before being weighed. The 

 guano was the best Peruvian, costing about three cents per pound. 

 It was crashed and sifted before using. In sowing the ashes 

 on plot 7, an error occurred in their application, and for the 

 purpose of checking the result, it was deemed advisable to repeat 

 the experiment on plot 10. 



" On plot 5, with 300 Ib^. of superphosphate of iime per acre, the 

 plants came up first, and exhibted a healihy, dark-green appear-
