Experiment 3.— WOLF’S SOAP. 
Solution, 4 ounces to 1 gallon of water. Sprayed on larvae feeding on 
walnuts. 
Result . — The larvae only changed their location for a branch higher up. 
Experiment 4.— COPPERAS WATER. 
Solution of 1 ounce to 1 pint of water. Sprayed two colonies of nearly 
full-grown worms. 
Result . — This seemed to destroy a very few larvae, and the remainder 
changed their location on the tree. 
Experiment 5.— COPPERAS WATER. 
Solution as in Experiment 4. Sprayed cluster on trunk of tree. 
Result . — They molted, and ascended the trunk and began feeding., 
Experiment 6.— SOLUBLE PINOLEUM. 
Solution of 1 part pinoleum to 32 parts water. Sprayed one cluster 
on leaves and another on trunk. 
Result . — There appears to be some reduction in the numbers of those 
feeding, and those on trunk were destroyed . 
Experiment 7.— SOLUBLE PINOLEUM. 
Solution of 5 parts of pinoleum to 100 parts water. Sprayed half 
grown larvae on branch high up in tree, so that I could only give them 
a slight whetting. 
Result . — None were injured, and, two days after, they were feeding as 
though nothing had happened. 
Experiment 8.— SOLUBLE PINOLEUM. 
Solution of 15 parts to 85 parts water. Sprayed copiously on cluster 
on trunk of walnut tree. 
Result . — About 50 per cent, were killed, some dying after the second 
day. The cluster became detached from the tree and fell to the ground, 
but a few larvae detached themselves from it, and again ascended the 
tree, and molted. 
Experiment 9.— AMMONIA WATER. 
Solution of 1 tablespoonful to 1 piut of water. Sprayed cluster on 
trunk of tree. 
Result . — They molted and ascended the tree. 
Experiment 10.— KEROSENE EMULSION. 
An emulsion, of equal parts kerosene, molasses, and water, was di- 
luted with three times its volume of water. Sprayed on cluster on 
trunk of tree.
