THE AMERICAN FARMER, 



produced. Its object 

 may be simply to invert 

 the sod, to slightly mel 

 low the surface of the 

 soil, or to penetrate into 

 the depths of the sub 

 soil and break it up 

 without bringing it to 

 the surface, or for vari 

 ous other purposes, 

 therefore it is very im 

 portant that the plow 

 should be adapted to the 

 kind of labor to be per 

 formed, and the depth 

 and time of plowing 

 should vary according 

 to the nature of the soil 

 and the crop to be culti 

 vated. Light or shal 

 low plowing cannot be 

 performed with a plow 

 designed for heavy 

 work, suited to that of 

 the sub-soil plow, 

 neither can deep plow 

 ing be well accomplished 

 with an implement de 

 signed for light surface- 

 work. Great improve 

 ments have been made 

 in these implements 

 within the past few 

 years, and one is led, in 

 seeing the complete suc 

 cess of the work per 

 formed by some of 

 them, to almost believe 

 that perfection has at 

 least been reached in 

 this department of farm 

 utensils; but as progress 

 and improvement are 

 ever inseparable from 

 intelligence and culture, 

 probably improvements 

 will continue to be made, 

 although it may be diffi 

 cult to tell how it could 

 well be accomplished.
