HISTORY OF THE THIRD YEAR'S WORK. 29 
grain was secured, but in a large proportion of the cases the stands of 
clover and alfalfa were unsatisfactory, which was perhaps due in the 
main to the fact that, in order to put the grain seeds deep enough in 
the ground, the smaller seeds were buried entirely too deep. How- 
ever, in practically all the rows planted some of the smaller seeds 
germinated, but in not a single case did the plants grow vigorously. 
By June 1 in spots only was it noticeable that any of the clover or 
alfalfa plants were alive, while the rye, barley, and wheat grew and 
developed well. Later, during February, and as late as during the 
early days of March, alfalfa and clover seeds, mixed with several 
varieties of spring wheat and oats, were sown, but, as in the other 
instances mentioned, only indifferent stands of the alfalfas and clovers 
were secured, and, while the uniformly excellent stands of oats grew 
and matured well, in no instance did the others do so. | 
These experiments, while they may be regarded as suggestive, are 
not to be taken as conclusive against the idea of mixing the smaller 
seeds with the larger, but they justify a substantial doubt of the prac- 
ticability of the idea on which the experiments were based. If clover 
and alfalfa seeds be sown on ground previously seeded to any of the 
grains mentioned, after the latter are up, it is quite possible, even 
probable, indeed, that good stands might be secured, and the plants 
grow well. It is practically certain that such of them as did so would 
be much benefited by being protected by the older and larger growths 
from the direct rays of the hot summer sun and the hot winds. The 
smaller seeds might be sown on the surface and covered by means of 
a light harrow where the others had been broadcasted; or where the 
others had been drilled the smaller seeds might be drilled between 
rows at proper depths. In either case no serious injury need result to 
the young rye, barley, or wheat; but on the other hand, the proba- 
bilities are that this surface treatment of the ground would materially 
benefit them by killing the weeds, loosening the surface, and inducing 
the absorption of moisture from the air—something nearly always to 
be desired during the hot months in the semiarid regions. 
A TENTATIVE SUCCESS NOTED. 
Another experiment on somewhat similar lines may be noted. Sev- 
eral varieties of beans and peas having running, clinging vines, as cow- 
peas, field peas, and velvet and other running beans, were sown in the 
same rows with many varieties of sorghum. In some of the rows the 
peas and beans were sown with the sorghum seeds, in others when 
the sorghum stalks were several inches tall. In every instance satis- 
factory results were secured. 7 
EXPERIMENTS WITH GRASSES. 
A large number of sowings of grass seeds were made between March 
28 and April 8. Practically everything that had been tested in the
