J. M. Miller, Berkeley, Calif., reporting on a regional survey 
of bark-beetle infestations says: "An examination was made of the moun— 
tain pine beetle infestaticn around Medicine Lake, in the Shasta National 
Forest, July 4 to 6, by Mr. Salman and Phil Johnson. This infestation was 
found to be continuing at about the same momentum az in 1930. * * * 
The survey party completed the 1931 sample plot and strip work on the 
Modoc and Shasta Forests by July 19. At that time the 1931 tendencies of 
the western pine beetle infestation were becoming evident on these areas. 
* * * All indications point to an aggressive and increasing infesta- 
tion. The base for this survey work was moved to the Sierra National 
Forests in central California July. 20. * * * Conditions found here indi- 
cate that the epidemic of western pine beetle infestation started in 1930 
and has already advanced to.a point where the 1931 losses are far greater 
than any that have previously occurred in the history of the area."

"The grasshopper situation in South Dakota and Nebraska contin- 
ued to grow more serious during July," says J. R. Parker, Bozeman, Mont., 
"and requests for assistance from this station were also received from 
Iowa and North Dakota. R. L. Shetwell was in South Dakota from July 10 
to July 30, acting in an advisory capacity to State and county officials 
and carrying on experimental work.***"Due to delays in securing an ef+ 
fective poisoned bran mash in sufficiently large amounts before grass~ 
hoppers reached the adult stage, the control campaign in South Dakota 
and adjacent territory in Nebraska was not successful and ina large area 
many crops were completely destroyed. Large-scale poisoning operations have 
been given up for the season and our efforts for the remainder of the 
season will be directed toward finding out where and how many eggs are 
being laid. This information will be absolutely necessary in planning 
for an intelligent control campaign next year." 
Iowa State officials were taken through the devastated areas in 
Nebraska and South Dakota and were accompanied back to Iowa by J. R. 
Parker, who states: "In the vicinity of Missouri Valley, Iowa, cornfields 
were found sericusiy damaged by the same species of grasshoppers (Melano— 
plus bivittatus Say and M. differentialis Thos.) that had devastated South 
Dakota and Nebraska. Several control demonstrations were made and State 
Officials were informed of the serious situation that exisied. Fifty 
thousand dollars was made immediately available and prompt measures wer?
