172 REPORT OF THE HORTICULTURIST OF THE 
shallow worked plats. The proportion of shallow roots on 
the other hand was greatest on the shallow worked plats. On 
the deeply worked plats, the horizontal roots were very few. ‘The 
roots appeared to diverge as they extended downward, reaching 
‘their greatest extent many inches below the surface, while in the 
shallow worked plats many roots grew nearly horizontal, so that 
the roots on these plats reached their greatest extent but a very 
few inches below the surface. 
The ground occupied by the roots might be coer la in the 
deeply worked plats by a short cone buried just beneath the sur- 
face, in its upright position, while in the shallow worked plats the 
cone would need to be inverted. 
The differences noted in the root growth correspond well with 
the observations upon the growth of the plants made during the 
summer. During June and the early part of July, before the soil 
had become very dry, the corn grew most rapidly on the shallow 
worked plats. In August, however, during a period of severe 
drought, the plants on the deeper worked soil overtook and sur- 
passed the others. T'be rich green foliage and vigorous appear- 
ance of these plants presented a striking contrast with the rolled 
and withering leaves of the plants on the shallow worked soil. 
Toward the end of summer a regular gradation in the height of 
the plants was noticeable, as well as in their stage of maturity, 
the tallest and least mature plants being those on the deepest 
worked plat. All, however, ripened before frost. 
The yield of the different plats, which may have some interest, 
is given below. It appears that the deepest and most shallow 
tillage gave the largest yield of corn, while the shallow tilled 
plats gave the smallest yield of stalks :
