In “processing” McQueen’s Inoculator, excess 
moisture is slowly removed as the organisms are 
being concentrated, under controlled conditions. No 
additional moisture is added later, as the correct 
amount necessary is determined while the “process, 
ing” is being completed. 
The finished McQueen “carrier” therefore con¬ 
tains sufficient moisture to support the organisms, 
but no excess moisture to develop mold growth. 
McQueen’s Inoculator does not mold, spoil or 
dry out prematurely , if stored under favorable seed 
storage conditions. 
THE McQUEEN CONTAINER 
C INCE practically all “humus” type Cultures are 
^ sold in fibre containers, too much moisture may 
cause not only the above difficulties, but may also 
cause the container to “break down” and damage 
easily. 
Radical changes of environment while displayed 
for sale should be avoided. McQueen Cultures do 
not change, or “dry down” rapidly from a high to a 
low moisture content after they reach the dealers’ 
hands. 
It is important to hold the moisture content of 
Seed Inoculation Cultures at a nearly constant level, 
therefore McQueens use an improved type of con¬ 
tainer (can) which is “insulated” both inside and 
outside, to insure holding moisture uniformly under 
average conditions. This advanced type can has 
been especially designed to meet the rigid specifica¬ 
tions of the McQueen Research Department. 
All McQueen Cultures are guaranteed to give sat¬ 
isfactory results, or are replaced free of charge. In 
addition, they also carry an expiration date of suf¬ 
ficient duration to allow Seedsmen to sell them, 
without the necessity and expense of returning or ex¬ 
changing them at too frequent intervals. 
McQueen’s method of preparation — selection oj 
straws—moisture holding “carrier”—and “insulat¬ 
ed can ” are all very desirable and important features 
of McQueen’s Inoculator. These time tested features 
enable us to conscientiously solicit your Inoculator 
business and give your customers a high grade
