nine cords per acre), composted from equal parts of peat mud, 

 sea manure and horse manure, all forked over together three 

 times, aud allowed to ferment each time. I then ploughed 

 (April 16th) the whole land eight inches deep, then harroAved 

 very thoroughly, until the sod was well pulverized. 



April 17th lot No. 2 was spread with the same amount of 

 manure of the same quality, and the whole land cross ploughed 

 four inches deep. Then lot No. o was manured in the same 

 manner as lots No. 1 and 2, and the whole land harrowed 

 thoroughly. April 18th the whole land was furrowed four 

 inches deep, and three and one-half feet apart ; and lot No. 6 

 was manured in the drill, with' the same amount and quality as 

 the previous lots. I then planted the whole land with Jackson 

 White potatoes, of small, but not the smallest, size, placing 

 them whole, ten inches apart, in the drills. 



Then spread upon lot No. 4 manure as upon the other lots, 

 and allowing it to remain upon the surface ; while lot No. 5 

 had no manure at all. 



I am aware that the experiment of lot No. 6 is not required 

 by the Society ; but it being the common way of applying ma- 

 nure for potatoes in this vicinity, I was induced to extend the 

 experiment for my own gratification ; and thinking others 

 might be interested by the comparison, I offer the result of the 

 whole. 



The first rain fell, after planting, May 19th, the land being 

 very dry until then. The potatoes were ploughed and hoed 

 three times before the middle of July. Upon the 20th of 

 July the potato blight struck the tops, but the crop was so far 

 advanced that they did not rot but little. The total amount 

 was reduced somewhat, but I think not very muck. The . 

 whole crop was harvested October 31st; the restilt of which 

 may be found in the annexed table, together with a brief 

 synopsis of the weather during the season.
