FISH OIL AS ADHESIVE IX ARSENATE-OF-LEAD SPRAYS 
11 
The flour used as one of the adhesives contained 16 per cent of 
gluten and was thoroughly mixed with the arsenate of lead before 
being brought into mixture in the spray tank. The day of the 
spraying was partly cloudy, with a temperature of 68° to 72° F.

The mixture spread fairly well over some of the foliage, but not well 
over that of white oak. It was only slightly better, if any, than the 
arsenate of lead used alone (fig. 9).

The proprietary miscible oil mixed readily with the arsenate-of- 
lead mixture. The day of spraying was partly cloudy; the spraying 
was done at a temperature of 70° F. Mixtures containing this 
material did not spread well over the foliage, especially that of the 
oaks (fig. 10).
