On June 24 and 25 Frank E. Todd and E. L. Sechrist, of the Davis, 
Calif., field laboratory, were in Stanislaus, Calaveras, Amador, and El- 
dorado Counties, Calif., making observations on the bees which had been 
moved into the buckeye territory. Two commercial apiaries, one of about 
50 colonies and the other of 120, were seen which had suffered severely. 
4n apiary of Carniolan-Italian bees located near the experimental Ital- 
ians, which suffered severely, in the buckeye territcry, did not show any 
symptoms of buckeye poisoning and is storing honey. The Carniolan—Italian 
cross at Three Rivers in Tulare County stored an average of 48 pounds per 
colony from buckeye and other flowers in the locality, with little loss 
of bees or brood. 
The use of various crosses of bees in two buckeye regions to de- 
termine comparative immunity or susceptibility to buckeye poisoning has 
been completed at the Davis laboratory and one lot of bees has been 
moved to the "Mineral King" region in the mountains of Tulare County, 
to an elevation of about 7,000 feet, while the other lot was moved to 
Strawberry, in Eldorado County, where the elevation is about 2,600 feet. 
These two lots of bees are being given an opportunity to recover in the 
High Sierras and to gather nectar from the numerous plants now in bloom 
there. Scale hives are located with these bees. The scale hive at 
Strawberry built out foundation and gained 8 pounds in weight in three 
days after being located. The honey appears to be water white and an 
abundant flow is promised over a long period, as the prevailing honey 
plants bloom over a considerable variation in altitude--up to 8,000 feet. 
Records have been secured of the honey produced by these bees and of their 
condition at beginning and end of the buckeye honeyflow. Two queen bees 
from the Strawberry—Placerville lot of bees have been brought to Davis 
and introduced into nuclei for a study of their behavior in recovering 
from the buckeye poisoning, or to learn whether they do recover satis— 
factorily. 
On June 2 to 9, George H. Vansell, of the Davis, Calif., field 
laboratory, investigated a serious outbreak of adult bee trouble near 
Yerington, in Mason Valley, Nev. There has been more or less of this 
disease every year since 1915, but this year the outbreak is more serious 
and has affected a territory having about 25,000 colonies of bees, ren— 
dering the most of them unprofitable this year, while numbers were com— 
pletely destroyed. About 75 per cent of the bees have been afflicted. 
Normally this valley produced 8 or 9 carloads of fine comb honey yearly. 
Smith Valley, where there are a few cases, produces about half that 
quantity. On June 15 to 21 Mr. Vansell made a trip to Ventura, Los An- 
geles, and Orange Counties, Calif., where trouble apparently similar had 
arisen. He secured similar data there, as well as records of the 
weather since 1914. 
On June 12 Messrs. Todd and Vansell were in Eldorado County, 
Calif., checking up on the dried fruit which had set in the pear 
orchards where experimental work with bees was being done.
