Delay in picking up figs increases moth infestation.——"Consider- 
ing Ephestia infestation alone," reports Perez Simmons, Fresno, "the 
records show that twice-weekly gatherings of Adriatic figs resulted in 
an infestation by Ephestia of 2.6 percent; weekly pickings, 3.7 percent 
infestation; and picking up every 10 or 11 days, 11.6 per cent infesta- 
tion. These results support our recommendation that figs should be picked 
up aS frequently as possible and at least once a week."

run, those dried under cloth would have brought about $36 per ton this 
year and the others about $15, a difference of $21 per ton. If sorting 
had been done, the figs dried under shade cloth would have been brought 
up to 90 percent good, worth $40 per ton; and, at a liberal estimate, 
the figs dried on exposed trays would have tested 80 percent good after 
Sorting, worth $27 per ton. In other words, an expenditure of $1.50 per 
ton for material, and possibly an equal amount for extra labor—total 
¢3-would have brought gross returns of $13 per ton above what was hypo- 
thetically receivable for the figs dried in the usual manner, or a net 
advantage of $10 per ton." 
TOXICOLOGY AND PHYSIOLOGY OF INSECTS 
N. E. McIndoo, Takoma Park, Md., states that the heading for par-— 
agraph 1, page 6, in the January 1933 Monthly Letter should have been: 
Tarsi of flies do not carry gustatory organs. 
BEE CULTURE

tive study of apiary organization and management, mentioned in the De- 
cember Monthly Letter, George E. Marvin, Somerset, Md., says: "It ap- 
pears more profitable to follow the plan of putting down into the brood 
nest combs of honey from the supers above and to save out full combs’ of 
honey to feed in the spring than to buy sugar, make up sirup, and feed in 
fall and spring. None of the cooperators who had to feed their colonies 
to keep them alive had an absolute crop failure. In 1930, the cost of 
Sugar alone for 16 cooperators amounted to $3,598.97 and in 1931 forl13 
cooperators to $1,816.47. In order to pay the sugar bill alone a large 
quantity of honey had to be extracted, tanked, pailed, and marketed. It 
seems a waste of time to go to all this trouble when combs of honey can 
be saved from the early crop for fall and spring feeding."
