first year these pollenizing grafts produced any blossoms. He also 
placed 10 colonies of bees in the orchard this year. The fruit marketed 
was 800 boxes. He intends to place twice as many colonies of bees in 
the orchard next year." 
Mr. Sechrist states further: "The outstanding thing so far de- 
veloping in this study is the limited areas in California in which rental 
of bees for pollination is practiced, or seems necessary. These areas 
can readily be supplied with bees while, in Oregon, and particularly in 
Washington, all the bees available in the State would not supply the needs 
of the fruit growers. In a number of fruit-growing sections of Califor— 
nia the bees are either plentiful naturally, or are moved near the or~ 
chards by beekeepers because of scarcity of nectar elsewhere, so that 
the pollination is not apparent." 
At the Somerset, Md., laboratory, according to Jas. I. Hambleton, 
"Work was continued on the determination of the per gallon weight of 
honey. The minimum weight of 12 pounds per gallon for honey has been 
considered for many years as the correct standard. In fact, the cor—- 
rectness of the figure has hardly been questioned. Recent studies made 
by G. E. Marvin and also by the University of Wisconsin indicate that 
there are a number of important commercial honeys preduced in the Uni- 
ted States which are lighter than 12 pounds to the gallon, and yet are 
excellent honeys, considered from’ the stardpoint of ripeness, bcdy, 
flavor, etc. In view of this fact, it will be desirable to specify a 
new minimum weight per gallon for honey in the revision of Circular 24, 
which describes the United States grades for honey. The study to date 
indicates that a weight of 11 pounds 12 ounces per gallon would not be 
too low. The specific gravity will be stated in pounds and ounces per 
gallon, with equivalent Baumé and Brix readings. In connection with 
the study of the specific gravity, an effort is also being made to work 
out an easy and accurate method which honey inspectors can use for read-— 
ily detecting honeys that do not meet the minimum weight specifications."

A. J. Ackerman, Bentonville, Ark., reports that "The results of 
the 1931 control experiments indicated the necessity of ccmbining oil and 
lead arsenate for efficient control of the ccdling moth (Carpocapsa 
pomonella L.) in this section. The white oils proved most promising. 
At the 1 per cent dosages in the first—brood cover sprays the oils show-— 
ed ovicidal as well as larvicidal effectiveness. As little as one-fourth 
of 1 per cent oil in the late sprays provided an excellent spreader and 
sticker for protection of coverage in the late applications of lead 
arsenate." 
Results of control investigations of the codling moth at Yakima, 
Wash., are reported by E. J. Newcomer, as follows: "Briefly, the re- 
sults show that the use of oil emulsion with lead arsenate decreases the
