On June 10 R. L. Furniss reported for duty at Klamath Falls, Oreg., 
where he was joined by J. A. Beal, and preparations were then made for 
putting the log examinations for the study of bark beetle infestation on 
a continuous basis. 
The mountain pine beetle control work on Crater Lake National Park 
was completed on June 20, with the exception of the rolling of a few in- 
fested logs, which had to wait for warmer waether. The work is in charge 
of W. J. Buckhorn. 
A heavy wind in April blew down an immense quantity of timber all 
through the Cascade Range. J. A. Beal examined one such area in Klamath 
County, Oreg., and reported that the attractive influence of these logs 
may result in concentrating attacks of the western pine beetle in the 
vicinity. It is not expected that the down logs will prceduce normal 
broods, 
Since June 17 most of the work of the locust borer control pro- 
ject at Columbus, Ohio, has been confined to the establishment of sample 
plots in cooperation with the Forest Service crew making a study of 
yield and volume in black locust. Results indicate that locust borer 
attack is definitely related to crown class, the most thrifty trees show- 
ing least attack and the least thrifty showing most attack. 
An outbreak of the periodical cicada (Tibicina septendecira L.) is 
reported from Ohio, where Brood V of Marlatt has emerged in the eastern 
part of the State. The cicadas are very abundant in the eastern part of 
Ross County, especially southeast of Chillicothe on the Scioto Trail 
State Forest. Adults were collected on this area on June 17. This in- 
sec. is causing serious injury to young trees of all species in that lo- 
cality by oviposition in the twigs, which later die and in many cages 
break off. Some black walnut trees were noted here that had 100 per cenit 
of the foliage killed as a result of oviposition by this insect. 
At the beginning of June Scotch pine plantations at Mount Toby, 
Mass., and the Harvard Forest were heavily attacked by the white pine 
weevil. Discussion with the Harvard Forest staff brought out the unan- 
jmous belief that the variety of Scotch pine in these plantations (Riga 
strain) would under certain conditions be vigorous enough to smother the 
young larvae after hatching and to recover completely. Accordingly pre- 
liminary observations have been mada and the foregoing premise seems to 
be true. In five plantations examined no dead leaders have been found. 
This study will be continued throughout the summer. 
Dr. H. J. MacAloney, in charge of the Amherst, Mass., laboratory, 
reports a rather heavy attack of the larch case bearer, and the charac— 
teristic browning of the needles was present in parts of the White Moun~ 
tains this spring. During the third week in June a heavy flight of 
moths was observed.
