Water was applied to the surface frequently until Mar. 25 
without any planting in order to secure complete adjustment 
of the water levels. In March 25 seeds of alsike, red-top, and 
timothy were sown, each species in one of the quarter areas of 
each cylinder. It was impossible to secure seeds of the blue 
joint and so the areas designed for this species remained va¬ 
cant until Apr. 12, when rhizomes were transplanted from 
the marsh meadow to the cylinders. 
Each of the four species thus occupied one quarter of the 
surface area of each cylinder and was enclosed in a wire basket 
placed as described above. The water gauges were adjusted to 
allow the water to stand as follows: 
Cylinder ISTo. I, at the surface of the soil. 
Cylinder Ho. II, 4 inches below the surface of the soil. 
Cylinder Ho. Ill, 8 inches below the surface of the soil. 
Cylinder Ho. IV, 12 inches below the surface of the soil. 
Cylinder Ho. Y, 24 inches below the surface of the soil. 
Cylinder Ho. YI, 30 inches below the surface of the soil. 
The water used was from the pipes of the green house and 
was applied by means of a hose to the surface of the cylinders. 
In cylinders I and II the surface was flooded for about 30 min¬ 
utes after each application. Evaporation would lower the 
water level in cylinder I so that much of the time it was slightly 
below the surface. During the greater part of the time the ex¬ 
periment was run there was no difficulty in keeping the water- 
level of the gauges. During the hot weather of June the water 
table usually fell somewhat below the level of the gauges be¬ 
tween the applications of water. Ait first the seedling in cy¬ 
linders I and II made the best progress. Aside from this there 
was no decided differences noticeable until May 6 when the 
following notes were recorded. 
Timothy. 
Cylinder I, 2*4 inches high, yellowish, doing poorly. 
Cylinder II, 6 inches high, green, doing well. 
Cylinder III, 7% inches high, green, doing well.
