bearing down, as he would do in the case of the surface plow, he 

 will only drive its wedge-shaped point deeper into the ground. 



The steel subsoiler (the one shown in Fig 67) has other uses 

 besides that of following in the furrow of the surface plow. The 

 smallest size, running six or eight inches deep and drawn by one 

 horse, is a capital cultivator for working between rows of corn 

 or roots, loosening the soil more deeply and more thoroughly than 

 any other implement. It should not, however, be run so near 

 to the rows as to cut off the spreading roots, nor should it be 

 used at all except during the earlier periods of growth. 



The larger sizes, running a foot or more deep, at intervals of 

 two feet in width, will loosen up a run-down or hide-bound 

 meadow or pasture, so that a top-dressing and subsequent roll- 

 ing will often restore its fertility, and postpone the necessity of 

 bringing it into cultivation. 



Land that has been plowed in autumn may be better prepared 

 for the planting of the next spring by the use of this tool — crossing 

 the field first in one direction and then in the other — than by the 

 use of the common plow. Of course, the harrow would be as 

 necessary in the one case as in the other.

The Collins Co. manufacture a steel plow, with Hayden's 

 patent subsoil attachment, shown in Fig. 69, which has the effect 

 of loosening up the hard-trodden furrow bottom.
