purpose. It is not to be fed to cattle or sheep or 
horses any more than acid phosphate or potash 
salts. 
The crystals of Nitrate of Soda vary somewhat 
in color, from brown to white, or gray. 
Order as early in the season as possible, and 
apply it early for best results. 
Nitrate is not to be put on wet foliage, and it is 
to be applied evenly. Both these precautions will 
enable you to avoid all danger of burning or destroy- 
ing vegetation. 
Your farmer or your gardener may be accus- 
tomed to use barn yard manure at the rate of a pound 
to a square foot. No commercial fertilizer should be 
put on any crop in such a quantity, since at such an 
extravagant rate its first effect would be to destroy 
or to badly burn any vegetation with which it came 
in direct contact. Direct contact of commercial fer- 
tilizers with seeds or vegetation is not generally 
advisable and direct contact is always to be avoided 
with wet foliage. All commercial fertilizers are best 
applied when the soil and foliage is dry. 
If you have any reason to suspect adulteration 
of the Nitrate you may buy, send several pounds of 
it to your Experiment Station for analysis, giving 
date of purchase, full name and address of agent, 
and of the Company which the seller represents. 
If you have any difficulty in obtaining Nitrate, 
either by reason of prohibitive prices or undue de- 
lays or on account of inability of dealers to supply 
you promptly, let us know at once, and the difficulty 
will be investigated immediately.
