WHY IT PAYS TO INSIST UPON GETTING 
MICHIGAN PEAT—SOIL SPONGE 
NATURE'S FINEST SOIL BUILDER 
jyriCHIGAN PEAT—SOIL SPONGE is rich 
* * brown peat moss, produced at Capac, 
Michigan from America's Choicest Peat Beds. 
It is pure organic vegetable matter which 
creates soil fertility—develops vigorous root 
growth—loosens clay soils and binds sandy 
ones. Briefly, MPSS replaces lost nutrients, 
enriches and re-vitalizes your soil — 
Economically — Efficiently — Permanently! 
Here are a few comparative facts :— 
MPSS is shipped with less water 
than humus. Being dryer, each ton 
contains more actual "peat" so that 
fewer tons are needed to accomplish 
the same results. 
MPSS is approximately 97% organic; 
the highest found in any similar peat 
or humus product. Extra organic 
means extra money to you and extra 
value to your soil!

3— Coverage MPSS averages 31/4 cubic yards to 
the ton; humus less than 2 yards. 
MPSS being drier, lighter and more 
fibrous covers greater areas with 
less tonnage and labor. 
MPSS is "humus forming" but out¬ 
lasts humus in the soil. It assimil¬ 
ates rapidly and will not float or 
wash away. 
MPSS is recognized as the Standard 
American Peat. Government Experts 
approve it and have specified it in 
contracts replacing imported foreign 
baled peats. 
Michigan Peat—Soil Sponge holds the U. S. 
Government Contract for Peat for 1939. It 
is packed in 25 lb., 50 lb. and 100 lb. bags. 
Also in 150 lb. crates — lowest prices on
