120 MASSACHUSETTS AGRICULTURE. 



years before using, it being deemed important that it sliould 

 acquire age. The proportion of loam to that of the night-soil, 

 is about as three to one. This mixture Mr. K. has used as yet 

 only upon grass land, but, says he, " I generally get double, 

 and sometimes treble the quantity which my neighbors do." 

 His opinion is, that guano is not the article for land in the 

 south-western part of Essex County. 



Probably the compound prepared by Mr. K. is much the same 

 as the poudrette of the ships, but better because uninjured by 

 any agent used for destroying the odor, in doing which probably 

 the poudrette receives damage. 



Mr. L. planted one-fourth of an acre of corn about the middle 

 of May, with no manure but the super-phospliate of lime. The 

 seed was dropped upon the super-phosphate. " The yield," 

 says he, " is about equal to that upon two other fields where I 

 put on from five to six cords per acre of the green manure." 

 About a common handful of the lime was put in each hill. 



Mr: M. planted his whole field of corn, containing 2,500 hills, 

 in the following manner. With the exception of four rows, 

 twentj^-one hills long, he first put half a table-spoonful of Pervi- 

 vian guano (Xo. 1) to each hill, and spread it about with his 

 foot. Half a shovelful of barnyard manure was then put upon 

 that, then a slight covering of soil, and then the corn was 

 dropped and covered. The four rows which had no guano had 

 a fair shovelful of manure to each hill. These four rows ran 

 through the middle of the field from north to south. The crop 

 upon the four rows with a shovelful of manure, weighed as fol- 

 lows, viz. : the two western rows seventy-seven pounds each ; 

 the two eastern ones seventy-four and a half pounds each. After 

 this, the two rows with half a shovel of manure and half a 

 spoonful of guano on west side of said four rows, were found to 

 have seventy-seven pounds of corn each, and the two manured in 

 the same way on the eastern side of the said four rows, weighed 

 seventy-one and a half pounds. The whole quantity of guano 

 put on the field was 146 pounds. The whole crop was thirty 

 bushels of sound, shelled corn ; the quantity of land was three- 

 fourths of an acre. In dollars and cents the account would 

 stand as follows : Six cords of manure, (amount for three 

 fourths of an acre,) would have cost in the ground, $24.
