NORTHERN GROWN SOIL BUILDERS 
Prof. Hansen's Cossack Alfalfa Takes Hard Knocks 
We have alfalfa seed from over 40-year-old fields of Cossack alfalfa that has 
survived 45 below zero cold, grasshopper plagues, meanest drought of the Thir- 
ties. Some crowns are a foot or more across, and the larger plants bush out to 
a diameter of 3 to 4 feet. Combined with Ranger alfalfa in a 50-50 mixture, you 
not only get higher yields of best quality alfalfa per acre, but also the hardiness 
and WILT RESISTANCE which assures LONGER LIFE.

Ranger-Cossack Alfalfa 50-50 Mixture: 1 bu. $48.50; 100 Ibs. $80.00 
WASHINGTON ALFALFA 
Because of very unfavorable weather conditions we have not harvested 
as large a crop of alfalfa as usual... and there will not be enough to go 
around. We have therefore secured a car of alfalfa from Washington state 
... trom that part of the state that comes closest to approximating our 
own climatic conditions.

—NEW ARASAN TREATMENT FOR ALFALFA SEED— 
We have added new modern machinery to treat alfalfa seed by the 
slurry method. If you wish your seed treated, add $1 per 100 pounds to 
the list price. We recommend this treatment for those areas where soy- 
bean fungus is a threat to new alfalfa. 
Announcing the newest 
RHIZOMA ALFALFA 
After years of work by the Canadian Experiment Station we have a most 
valuable contribution for the American farm and ranch. Here is a new highest 
yielding alfalfa for hay and the first real practical pasture-type alfalfa. It 
combines the extreme hardiness of the Siberian Semi-Palatinsk pasture-type 
alfalfa which we have tried on the Bober Seed Farms and the highest 
yielding strain of Grimm alfalfa. . .. It stood more below zero weather in 
Canada without any winter-killing than any other known strain. ... Outyielded 
all other strains in yield of No. 1 quality hay. Stands pasturing and tramping 
by livestock without material injury. ... Mixed with Lincoln Bromegrass it will 
produce MORE BEEF per acre. ... Planted by itself in rows 3 feet apart at the 
rate of 14% pounds per acre, will send out runners like strawberry plants and 
cover the field with most productive alfalfa.
