2 E2 FUMIGATION METHODS 
of prominence, the red scale ranks next to the black 
scale in California. The red scale is also familiar to 
fruit growers in the colonial orchards. Considering all 
things, Professor Lounsbury is of the opinion that 
fumigation conducted by the contract system would 
be more advantageous to the colony than that done by 
local organizations. There are only a few slight dif- 
ferences in the methods of operating and handling 
sheet tents. The derrick-poles used in the colonial 
orchards for manipulating the tents are very much the 
same as those employed in California. The dome- 
shaped covers, known as bell tents, are used. 
Inarecent circular Professor Lounsbury makes the 
following statement: ‘‘ Californians have demonstrated 
that they can grow citrus fruits at a profit, in spite of 
the heavy expense of fumigation. They fully realize 
that they may have to keep fumigating for an in- 
definite time. ‘Their hope is, as ours, that efficient 
natural enemies of the scale insects will be found in 
the future. For South African fumigators it is espe- 
cially recommended that changing poles be adopted for 
small sheets. A few colonial parties have fumigated 
for the white peach scale, Diaspis amygdali, and con- 
sider the remedy economical and satisfactory. If light 
weight sheets, handled with changing poles, were 
used it is probable that the gas treatment for this scale 
would become popular with a large number of our 
fruit growers.’’
