Cylinder VI. Hoots 24 inches, as in V. Stems 11 inches, 
more erect than in V. 
This development in relation to the water and soil levels is 
graphically shown in Plate XXIII. In this experiment we note 
that timothy barely existed in cylinder I where the root and 
shoot growth was decidedly inhibited. Here the upper 1% 
inches of soil was practically one mass of fine roots. The best 
general development was in cylinders III and IV where at 
least one-half of the length and one-fourth of the total root 
mass was in the water. In cylinders V and VI with the water 
level close below the tips of the roots and the roots growing in 
soil of high capillary power the development of roots was some¬ 
what less and that of the stems decidedly less than in cylinders 
II, III and IV. 
Red top. 
Cylinder I. Roots 17 inches deep, mostly in upper 7 inches. 
Stems 7 inches, yellowish, poor leaf development. 
Cylinder II. Roots 24% inches deep, well developed below 
water level. Stems 15 inches, leafy but yellowish. 
Cylinder III. Roots 29% inches deep. Stems 19 inches. 
Cylinder IV. Roots 24 inches deep. Stems 15 inches. 
Cylinder V. Roots 23 inches deep. Stems 17 inches. 
Cylinder VI. Roots 25%' inches deep. Stems 17 inches. 
Red top grew poorly in cylinder I with the water at the 
surface and it made its best growth in Cylinder III with the 
water 12 inches below the surface of the soil. There were no 
marked differences in the other four cylinders. In II, III, and 
IV the roots grew well in the free soil water and the general 
development was nearly the same as in V and VI where the 
roots developed above the water table. See Plate XXIII. 
Blue joint.

inches, fruiting, leafy, yellowish. 
Cylinder II. Roots 26 inches. Culms 20 inches, fruiting. 
Cylinder III. Roots 33 inches. Stems 24 inches, fruiting.
