July 27 and they began to lay eggs on August 11. One weevil has laid 
119 eggs. The eggs thus far examined, however, have been infertile. 
It is important to know that more than one generation of weevils is pos— 
sible when food conditions are favorable, as it applies to crops of early 
and late peas grown in the same territory, the practice in some parts 
of Oregon." 
Pea—counting machine developed.—-— Mr. Brindley describes a piece 
of apparatus devised ta facilitate the work of counting peas. It "con= 
sists essentially of a board 1/4 inch thick, perforated by 500 5/16 inch 
holes set over slide and drawer. The holes are filled by spreading 
peas about the top. * * * One 500~pea sample can. be counted and sack— 
ed in 1 minute. This machine has already been copied by the pea-grad— 
ing laboratory at the University of Idaho and by one of the leading pea 
sia eg 1k

Improvement in honey-heating apparatus.-- "Several changes have 
been made in the apparatus for heating honey," reports G. E. Marvin, 
Somerset, Md. "The principle is that the honey is run over a heated plate, 
coming in contact with the heat for only about 1 minute. It is apparently 
possible to heat honey much higher than 160° F., which has been believed to 
be the maximum, without damaging it. In trial runs honey just as it 
left the hot plate registered 180° to 185° F. without apparent harm. 
Further refinements will have to be made in the apparatus before it can 
be recommended to the trade. Difficulty is still experienced by the 
formation of fine scum after the honey is run into the bottles. However, 
this type of apparatus has a number of advantages. Bottling can be 
Started after preliminary heating of only half an hour, and it is not 
essential to heat a large volume of honey at any one time. By the use 
of heating in excess of 160° F., the honey is thoroughly pasteurized."

Tartar emetic-molasses spray does not deteriorate with age.—— 
QO, C. McBride, in charge of the field laboratory at Honolulu, Hawaii, 
has conducted a series of tests of a tartar emetic-molasses bait spray, 
which has been found of value against the Mediterranean fruit fly (Cerati- 
tis capitata Wied.). The material in these tests was atomized on paraf-— 
fin paper and flies were introduced into the cages 5, ll, 15, .and 25edagm 
later. The conclusions drawn from the experiments are stated by Mr. Mc— 
Bride as follows: "On the basis of the data presented herein, the toxic 
principle of the tartar emetic—molasses Spray does not deteriorate with 
age. The spray is lethal so long as a sufficient quantity of,the spray 
remains available for a toxic dosage. Under field conditions the spray 
remains effective and is governed by the elements of the environment. 
Washing of the spray by rain would be the greatest limiting factor."
