degree of nitrogen-fixing power. Prepared 
in convenient form for immediate use, it 
is merely necessary to moisten the seed 
with the culture before planting. The 
bacteria multiply on the roots of the plants 
and make the crop the greatest factor in 
adding nitrates to the soil, instead of tak- 
ing them away. 
This means earlier maturity, larger 
yield and greater food value for the crop 
itself, and added nitrates in the soil in the 
most soluble form for other crops. 
The United States Department of Agri- 
culture says: 
**The Pure Culture Method has 
come to Stay.’’ 
VETCHES 
Vetches are coming into rapid favor as 
one of the most valuable of fall cover 
crops, since they will grow luxuriantly in 
many places where it is difficult to grow 
peas, beans or other legumes. Barren, 
sandy soils can, in a few years, be made 
into exceedingly fertile land by the work 
of the FARMOGERM bacteria on the roots of 
this plant. When planting grain, such as 
oats, rye, or barley, a bushel of vetch seed 
treated with FaRMOGERM and planted with 
the grain will develop nodules, adding 
nitrogen to the soil to be taken up by the 
growing grain cropand to enrich the land 
with an added supply of nitrogen for fu- 
ture crops of any kind. After harvesting 
the grain, the vetches will make a quick 
second growth, which can be turned under 
as green manure or will make an excellent
