PROF. HANSEN'S SIBERIAN COSSACK ALFALFA 
Grows in Every State in the Union 
The Most Profitable Crop You Can Grow 
Farmers of the prairie states are planting 
more Cossack Alfalfa each year. Because— 
It produces more and better hay than any 
other alfalfa. It makes better pasture, is 
more drought resistant because of its spread- 
ing root system. It will withstand the most 
severe winter weather without injury. 
ASIATIC BLOOD TURNS THE TRICK 
In a three-year trial at the leading mid- 
western state experimental station, Cossack 
alfalfa yielded more than twice as much per 
acre than northwestern and five times as 
much hay as southwestern alfalfa. 
LESS SEED MORE HAY PER ACRE 
You can secure a stand with two pounds 
less seed per acre of our Siberian Cossack 
alfalfa, because this hardiest alfalfa is a 
bushier plant and produces more and finer 
stemmed alfalfa hay per acre than other 
strains. 
COSSACK ALFALFA SEED IS CHEAPER 

Prof. N. E. Hansen and a 
Single Plant of Cossack 
Alfalfa 
Cossack alfalfa seed costs a few pennies more, but is cheaper 
than any other alfalfa in the long run. It is hardier, longer lived 
and best yielding. Most prominent farmers and stockmen in every 
state recommend it. The purity is 99.5 per cent.
