Mr. Scott said that he had made similar experiments in Georgia 
looking to the control of the San Jose scale and had obtained gratify- 
ing results. He had used a 25 per cent strength of crude oil with 
water on peach and plum trees, spraying in the winter time, with the 
results that the scale had been effectually destroyed and the trees 
not damaged. He had found, however, that the undiluted crude oil 
killed peach trees outright, as did also refined kerosene. He had 
used the Pennsylvania crude oil registering 43° on the Baumé oil 
seale. The high price of the crude oil, as purchased from the Stand- 
ard Oil Company, made it more expensive than refined kerosene, and 
for that reason, and because of its variable character, he did not rec- 
ommend it for general use. For three years he had used a 20 per 
cent strength of kerosene with water as a remedy for San Jose scale, 
and the results were all that could be expected from the application 
of any spray whatever. He said that at the recent meeting of the 
Georgia State Horticultural Society the general expression from the 
fruit growers was to the effect that the San Jose scale was no longer 
feared since the kerosene treatment had proved so effective. He said 
that infested orchards of more than 100,000 trees each were being 
successfully treated. 
Mr. Felt suggested that perhaps the San Jose scale did not become 
so dormant in Georgia as it did farther north, which would explain 
the successful use of comparatively weak applications of insecticides. 
Mr. Scott replied that this was true, as he had frequently found 
the seale breeding on warm days in midwinte:. 
Mr. Kellogg expressed a surprise that the price of crude petroleum 
should be so high, and suggested that it might be obtained at a 
reasonable price direct from the oil wells. 
Mr. Gillette then presented the following paper: 
NOTES ON SOME COLORADO INSECTS. 
By C. P. GILLETTE, Fort Collins, Colo. 
Nysius minutus has been unusually abundant in portions of Colo- 
rado this summer, and numerous inquiries have been received con- 
cerning it. 
My attention was first called to it by being told that it was destroy- 
ing the strawberries upon the experiment station grounds. A visit to 
the strawberry patch was made at once and the bugs found in large 
numbers upon leaves, fruit, and blossoms, but most numerous upon 
fruit, both green and ripe. They were not giving special attention to 
strawberries, however, as they were much more abundant on some of 
the weeds growing between the rows, and particularly were they abun- 
dant upon wild mustard and Monolepis nuttallii, wilting the plants to 
the ground. Plants of yellow dock, and even Helianthus, were liter- 
ally covered with them. In fact, hardly any species of plant in the
