{Ag. Bep.^ 1850, f. 371.) And in a later report lie says : Very deep 

 plowing and snbsoiling have not been practiced to much extent, 

 though, when done, the results I believe have been satisfactory. {Ag. 

 Jiep.lS52,p. 246.) James L. Cox, of Muskingum county, says: 

 Many ftmners are using the subsoil plow, and nowhere do they tell 

 better than in our clay wheat land hills. First, they stir the gi'ound 

 deep, that in a heavy rain it may be prepared to retain the water, and 

 thus prevent its washing the soil, or forming gullies. {Ag. Hep. 1851, 

 p. 400.) 



7. Indiana.— ls'Aa.c Kinley, of Henry county, says : Deep plowing 

 is becoming much more common, the effect of which is abundantly 

 evident in the increase of crops. {Ag. Hep. 1851, j!>. 429.) W. W. 

 Bunnell, of Wayne county, says ; Some experiments this season in 

 deep plowing more than double repay tlie labor, both for com and 

 wheat. As attention is paid to better modes of preparing the ground, 

 the crop is increasing. {Ag. Rep. 1851, jj. 430.) S. S. Boyd, of the 

 same county, says : Our corn ground is not generally plowed more 

 than six inches deep, but I am sati.'rfied that deeper plowing would 

 well pay for the extra labor from some experiments which have been 

 made in the vicinity. {Ag. Bep. 1852,^). 309.) 



8. Illinois. — Samuel Colcord, of Bond county, says : There are 

 farmers wdio have planted coni on the same ground ever since they 

 commenced farming, say for twenty-five years, witliout changing their 

 seed or plowing deeper than at first, still there are some who are bold 

 enough to differ from tliem, and who, after their grounds have become 

 a little worn, venture to let their plow in to the depth of from six to 

 ten inches, and thus, without manure, obtain double the crop of their 

 old-fashioned neighbors. {Ag. Bep, 1850, j9. 198.) 



9. Michigan. — W. T. Howell, of Hillsdale county, says : "NYhen 

 the land becomes impoverished by a succession of crops, bad hus- 

 bandr}", or any cause, this simjde method of plowing deeper or sub- 

 soil plowing is all that is necessary to restore it, and this only when 

 the farmer neglects rotation of cro|)s, clover and plaster, or refuses to 

 return to the land, in numure, the crops which he has taken from it. 

 {Ag. Bep. 1847,^. 404). Chester Hunt, of the same county, says: 

 Instead of plowing six or seven inches deep, as we were wont to do, 

 while our farms were new, many are setting the plow ten inches deep, 

 and, bv bringing the latent ]>ropertie3 of the sul)S()il into action, our 

 crops are increased. {Ag. Bep. 1852,^. 275.) Linus Cone, of Oak- 

 land county, says : Fourteen years since I commenced an entirely
