Stout—Vegetation of a Typical Wild Hay Meadow. 447 
During the latter part of Tune the heat in the green house 
became rather excessive for the best development of these plants. 
By July 1st it was evident that the crop had reached its best 
development under the conditions and so from July 9 to 11 
the final data were taken on the aerial development and the 
baskets were dug out to determine the facts concerning the 
root development. 
The cylindrical baskets were easily removed. The tops of 
those plants growing within the area included in a basket were 
of course attached to the main roots included within that basket. 
In a few cases roots extended slightly below the bottom of a 
basket and in those cases it is possible that some of the finer 
and deeper rootlets were broken off in the process of removing 
the baskets. 
A fine stream of water from a hose was used to wash the dirt 
from the roots within the basket and the development of the 
roots was studied as to depth of penetration and degree of de¬ 
velopment at the various levels. 
In all cases the plants growing within the area of the bas¬ 
kets were typical of those of that segment. The measurements 
of root and shoot development were taken from the surface of 
the ground. The culm measurements were taken to the tips of 
the longest leaves. 
The final data on the plants are as follows: 
Timothy. 
Cylinder I. Boots 5 y 2 inches, dense mass of fine roots in 
upper iy 2 inches of the soil. Stems 6% inches, leaves yellow¬ 
ish and sparse. 
Cylinder II. Boots 24% inches, dense in upper 4 inches. 
Stems 141/2 inches, leafy and yellowish green. 
Cylinder III. Boots 27 inches, denser in upper 6 inches. 
Stems 19 inches, leafy, green, fruiting. 
Cylinder IV. Boots 24 inches, dense in upper 6 inches. 
Stems 26 inches, leafy, green, fruiting. 
Cylinder V. Boots 16 inches, denser in upper 6 inches. 
Stems 11 inches, green and leafy.
