(Ephestia elutella Hbn.) and the cigarette beetle (Lasioderma serricorne 
Fab.) Mr. Reed reports: "On June 1 and 2 we Supervised the fumigation 
of 1,590,080 cubic feet of tobacco: warehouses in cooperation with one 
company, and 5,605,195 cubic feet in cooperation with another company. 
The warehouses were ventilated on June 5 and the test lots of insects re- 
moved on the day following. * * * These warehouses were again fumigated 
on June 28 and 29 and will be ventilated on July 4. * * * On June 15 
we cooperated in the fumigation of 4,500,000 pounds of flue—cured tobacco 
and also in the fumigation of 800,000 pounds. Apparently good results 
were obtained using dosages of 16 and 20 ounces of liquid hydrocyanic 
acid per 1,000 cubic feet. * * * On June 16 we cooperated in the fumi- 
gation of more than 8,000,000 pounds of imported tobaccos in Winston- 
Salem, N.C. A dosage of 16 ounces of liquid hydrocyanic acid per 1,000 
Cubic feet was applied and apparently good results were obtained. On 
June 17 we supervised the fumigation of 725,000 pounds of flue—cured to- 
bacco in Washington, N. C. A dosage of 2 1/2 pounds of sodium cyanide 
per 1,000 cubic feet was applied according to the formula 1-1 1/2-2; 
fifteen wooden barrels of 50 gallons capacity were used to generate the 
hydrocyanic acid gas; each barrel contained a charge of 20 pounds of so- 
dium cyanide." 
Ground cloths for spreading -under fig trees.--Perez Simmons, 
Fresno, Calif., reports: "A group of 10 trees of the Adriatic variety, 
located in the Forkner fig tract, were measured for ground cloths. * * * 
A random sample of 22 Adriatic trees at Lone Star, measured May 11, 
ranged from 9 to 27 feet in spread. The same number of Mission trees 
at Lone Star spread from 12 to 34 feet. These figures show the range in 
Size or fig trees in orchard plantings and the probable necessity for 
ground cloths of different sizes. Widths of 6 and 9 feet are proposed 
for use in our experiment, as tobacco shade cloth is obtainable in widths 
Of 3 feet or multiples thereof," 
Pea weevils active at Moscow, Idaho.--Tom Brindley reports that 
"The pea-growing section of the Palouse area of Idaho and Washington is 
experiencing one of the worst weevil years in the history of the industry 
in this section. The weevils are so numerous in the vicinity of Moscow 
Mountain that almost all of the early planted fields will be practically 
a total loss. The weevils began leaving their overwintering quarters 
during the second week in May. The first weevils were found on volunteer 
peas on May 11 and by June 6 the numbers had reached a point where 9 wee- 
vils could be collected in 100 sweeps of a net. On June 11 a maximum of 
1,123 weevils were collected in 100 sweeps. On planted peas the first 
weevils were collected on June 3. In one planted field the numbers in- 
creased from a maximum of 4 weevils per 100 sweeps on June 7 to 206 wee- 
vils on June 10 and to 1,418 on June 18. Collections of this kind have
