MANURES. 131 



another fourth part of the manure to plot No. 2, and then cross plough 

 the Avhole field to about half the depth of the first ploughing. Spread 

 another fourth of the manure upon [)lot No. 3, and harrow or cultivate 

 the whole field ; after which sow or plant the whole evenly, with any 

 crop preferred. Finally, spread the remaining quarter part of the manure 

 upon plot No. 4. 



" Observe that by pursuing this coui'se, each of the five lots will 

 receive equally, a deep ploughing, a shallow ploughing, and a harrowing 

 or cultivating, the only difference in them being that in No. 1 the manure 

 is buried deep, in No. 2 shallow, in No. 3 buried only slightly, but coated 

 Avith loam, and in No. 4 left exposed upon the surface ; while No. 5 gets 

 no manure. The manure is to be spread broadcast and as evenly as 

 possible. The after cultivation should be the same on each of the lots, 

 and the harvest of each should take place at the same time. * * * 



" This experiment is to be continued through a rotation of three years, 

 but no manure is to be applied to the second or third crop. The rota- 

 tion would be preferi'ed if limited to corn, grain and grass, but is 

 optional." ****** 



[As these experiments are to be continued through a course 

 of three years, no report, except of progress, will be expected 

 until the third year, 1862. Three entries were made in this 

 department, and the competitors, severally, furnished the re- 

 quired statements, of which the following are abstracts. — Sec.^ 



Statement of Isaac B. Woodward. 



The lot on which my experiment was tried contains twenty 

 square rods. The soil is rather heavy, being a black loam upon 

 a clay subsoil, is moist and retentive of manures. The crop 

 of 1859 was potatoes, manured at tlie rate of about three cords 

 of horse manure to the acre. For the present crop it was first 

 ploughed eleven inches deep ; manured with one hundred and 

 twenty bushels of green manure of neat stock, thirty bushels 

 to each of the four lots ; was planted with corn May 9th, the 

 corn being dropped by hand and covered with a hoe, and was 

 lioed three times, using the cultivator the first and last times, 

 and ploughing the second time. 



As soon as my corn was planted the wire-worm commenced 

 to destroy it, and what little did come up the cut-worms took 

 at the halves, so that I could not liave any experiment this year, 

 but 1 hope for better success with wheat next year, and grass
