High-Grade Fertilizers 
We have carefully considered the needs of our customers In making: up our list of Fertilizers, and in the following 
list will be found brands with balanced analysis to meet the needs and requirements of the most exacting grower, 
whether he raises Vegetables for market or home use, grows Grain and Grass crops. 
We recommend the use of the higher grade Fertilizers, as experience has proven that the high-grade fertilizers 
are much more economical to use than the lower grade goods at cheaper prices, as the cost of bags, labor, freight, 
drayage, storage, and other items of expense is the same per ton on low-grade goods as on the higher grades. 
Prices of Fertilizers given below are the prices in effect at the time this catalogue goes to press. All subject to 
change. 
Uses of Main Plant Foods 
NITROGEN —Promotes leaf and stem growth; increases 
proportion stalk to fruit, and hastens blooming. An ex¬ 
cessive amount delays maturity. 
PHOSPHORIC ACID— Stimulates early root formation; 
gives vigorous start to plants; increases ratio fruit to 
stalk; improves quality of fruit and hastens maturity of 
crop. 
POTASH —-Is important in sugar and starch formation; 
gives stiffness to stalk; helps plants to resist disease, 
and improves quality of fruit. 
Most soils furnish some of these elements and will keep 
plants alive; but often do not contain enough food to in¬ 
sure a proper and healthy development. Fertilizers must 
be used to supply a large part of the missing elements.
