OTHER INSECTS, TREE WASHES, ETC. 
Good results can be obtained in the eradication of aphides (plant lice) and 
•other insect pests by the use of Tobacco Water or diluted Whale Oil Soap. 
To make the Tobacco Water, boil up a kettle of tobacco stems and water; 
strain when cool and dilute with more water to about the consistency of weak 
lye. Apply to the tops of small trees with a common garden sprinkler; for use on 
larger trees a small force pump, with hose and spraying nozzle, becomes necessary. 
The Whale Oil Soap mixture is made by diluting one pound of Whale Oil 
Soap in seven gallons of water. Apply the same as the tobacco mixture. 
A good wash for the trunks of trees is made by dissolving one pound of potash 
in two gallons of water. This applied to the trunk and larger limbs will free 
the trunk from bark lice and will also aid the growth of the tree. As a wash for 
trees, this is far preferable to whitewash; it can be applied with an old brush or 
broom.
