SUMMARY OF ALFALFA SOWING. 523 
indications are that it will be a heavy yielder. The 
stems are finer than those of the common alfalfa, 
very thick and the foliage is of fine quality. It 
would seem that this would be an excellent variety 
for the cornbelt as well as the northwest, but at 
present the seed is scarce and high-priced. In a 
few years there will be more of it for distribution 
and data about it will by that time be more com- 
plete. 
Semipalatinsk.—This variety has coarser foliage 
than the other Siberian varieties, and is more 
branching and recumbent in its habit of growth. It 
was hoped that it would be a great pasture plant 
on the arid western plains. In general character- 
istics it resembles the Grimm, but due to its coarse- 
ness it is doubtful whether it would make as good 
hay, especially if it were grown on fertile soil. 
Baltic—tThis variety so closely resembles the 
Grimm that there does not appear to be any reason 
for keeping it as a distinct variety. 
Danger in Using Too Much Acid Phosphate.— 
That there is danger in using too much acid phos- 
phate on alfalfa meadows was clearly demonstrated 
to us on Woodland Farm the past season (1915). 
Two of our alfalfa meadows are separated merely 
by a farm road and have both been seeded the same 
length of time and treated in the same manner, 
except that one has had several applications of acid 
phosphate while the other has had basic slag instead. 
Ordinarily we cannot see much difference where
