of Lexington, Mass., : a cord of fresh dung converts twice 1 kc 

 Imlk of peat into a manure of equal value to itself that is, a 

 cord of clear stable dung, composted with two of peat, forms a? 

 manure of equal value to tliree .cords of green dung. 



Mr. S. L. Dana, of Lowell,, Mass., wrote a book, a few years since, 

 for the purpose of showing that ,peat mixed with an alkali, in all re 

 spects resembles, and, as a manure, is equivalent in effect to cow dung. 

 The cost per cord, at that time, he estimates as ; 



1 Cord peat and digging, - - - $1 .50 



92 I!)?, potash at 6 cents, $5.52 *) 



Or 61 Ibs. soda ash at 4 cents, 2.44 | 



Or 24 bush eornmon wood-ashes } average &amp;lt;of alkalies, 3.65 



at 12},&amp;lt; cents, - - - 3.00 | 



3)10.96 



$3.65 Per cord $5.15 



&quot;Were they really good hard- wood-ashes, about 16 bushels would be 

 sufficient, but an excess is allowed to compensate for variation. At 

 that period, clear cow dung was purchased by the Print works at an 

 average cost of 174-5 cents per bushel, or $17.45 cents per cord, at 

 times even higher. 



We must he e complete our very imperfect remarks on manures, as 

 the subject is sufficiently extensive to fill a much larger volume than 

 this. The teacher will find all that he can require in the American 

 M tcJc Book, by D. J. Browne, 12 mo. pp. 429, published by C. M. Sax- 

 .ton, New York, 1852. 



For the sake of convenience, however, we add a list of the articles 

 used in various countries as manures, designating with an asterisk (*) 

 sue& as can probably be of service in the United States.
