Experiment 6. November 23, 1894, 85 trees were sprayed with 
150 gallons of kerosene emulsion diluted with 12 parts of 
water to one of emulsion. The weather was cold and very windy.

Experiment 7. November 23, 1894, 71 trees were sprayed with 
150 gallons of kerosene emulsion diluted with four parts of water 
to one of emulsion. Weather same as experiment 6. Oost per 
tree, .021 cent. Owing to the wind much of the emulsion was 
wasted. 
Experiment 8. December 13, 1894, 150 trees were sprayed with 
150 gallons of kerosene emulsion diluted with 15 parts of water to 
one of emulsion. The weather was mild with but very little 
wind. Oost per tree, .003 cent. 
Nearly every tree sprayed both at Hector and Geneva were 
badly infested with the scale. The old mother scales were dead 
but the young larvez were hibernating in great numbers on the 
undersides of the twigs and in crevices in the bark of the trunks 
and large branches. 
We are unable at this time to determine what percentage of 
the scales were killed by the treatment, but it is expected thata 
more detailed account of the experiments together with results 
will be published in the fall. } ,
