PIONEER I 
GPM Peat Moss is a virgin soil, formed 
centuries ago by the growth and decay of 
mosses and various aquatic plants. It has 
many uses in gardening. 
1. Organic material, contributing to humus 
content of soil. 2. Assures constancy of mois¬ 
ture about the plant root level. 3. Has spe¬ 
cial root growth promoting substances. 4. 
Lightens heavy clay soil. 5. Binds and holds 
moisture in sandy soil. 6. Free from fungus 
growth and weed seeds. 7. Clean, odorless 
and pleasant to work with. 8. Economical to 
use. 9. Good winter mulch, as it insulates 
soil against frequent freezing and thawing 
effects. 10. Good summer mulch, as it con¬ 
serves moisture and prevents soil from bak¬ 
ing and crusting. 11. Reservoir for plant 
food. 12. Fine medium for packing and 
storing bulbs, roots and fruits. 13. Enables 
you to grow healthier evergreens, as it sup¬ 
plies a desired acid reaction. Mix with top 
soil at the rate of 25% Peat Moss and 75% 
soil. 14. Good basic soil material for lawns. 
15. Conveniently packed. 
“GPM” is packed in tightly compressed 
bales, burlap wrapped, well sticked and wire 
strapped. And, each bale of “GPM” con¬ 
tains twenty (20) bushels of loose Peat Moss 
—even though the bales will be of different 
weights—which will cover between 250 and 
300 square feet, one inch deep. It is not sold 
by weight because the weight of the bale is 
dependent upon the technical moisture con¬ 
tent at the time of baling and varies in ac¬ 
cordance with atmospheric conditions. 
“GPM” is of superior quality and the 
finest medium that money can buy. There 
is only one “GPM” brand—the pioneer 
Granulated Peat Moss, in all America. 
PRICE 
$4.00 per 20 Bushel Bale, F.O.B. Dundee, 
Ill.; $1.25 per 2 Bushel Carton. 
Hill Evergreen Tree Food 
This is a special formula containing 10% 
nitrogen and other elements, which we have 
found through extensive experiment, produce 
best results with Evergreens. Not only will 
the growth and the general health of the tree 
be benefited, but the color will be more 
pronounced when trees are properly fed 
using this food. 
Directions for application: Use one-half 
pound per foot in height of tree, example: 
2- foot trees, 1 pound fertilizer. 
3- foot trees, 1^2 pounds. 
4- foot trees, 2 pounds. 
Larger trees in proportion. 
PRICE 
Put up in 25-pound sacks, $1.50 per sack. 
($5.00 per 100 pounds.) Ready for shipment 
from Dundee by Freight, not Prepaid. Com¬ 
plete directions with each bag. 
The Garden Club Shrubbery Protector 
At last an invention that protects Evergreens from 
dogs. An almost invisible protector made of steel spring 
wires, rust proof. Each protector has three prongs and 
covers a quarter of a circle. If the tree is against the 
house or wall, two protectors are enough. This is a tested 
device that has proved very satisfactory. 
Price, $1.95 per dozen, F.O.B. Dundee.
