88 FUMIGATION METHODS 
in Riverside County from fumigation with cyanide has 
been caused by an occasional mistake of the foreman of 
fumigation in either beginning his work too early in 
the evening or continuing it too late in the morning. 
This has, however, seldom occurred, as few fumiga- 
tors who understand their business will risk their 
reputations by taking such chances. I recall to mind 
a suit brought against the county some years ago for 
alleged damages by one of our growers. This, I un- 
understand, was a case of daylight fumigation. 
‘*T quite agree with the advocates of daylight 
fumigation that there would be some advantages 
gained by doing the work in the daytime instead of 
night. There would bea small saving in chemicals, 
but not nearly so much as claimed by some. It would 
be also easier to locate trees and move the apparatus 
from place to place. On the other hand, there are 
some advantages in doing the work at night. The 
handling of a fumigating outfit, especially where large 
tents are required, is very laborious. Men could do 
more work with less fatigue on account of the cooler 
temperature. ‘This would be especially true in River- 
side County, where the greater part of the fumigation 
is done during the warm months. I am under the 
impression that it would be difficult to get men to work 
during the very warm weather in the daytime, as the 
reflection of the sunlight on the tents would increase 
the heat to such an extent that they would prefer 
other work at less wages. As was intimated at the 
beginning, it is probable that in some of the coast 
counties, in fumigating for black scale, where the 
amount of cyanide is much less than for red scale,
