The trustees of the college have author-

CONFERENCE ON FORESTRY 

 EDUCATION 



A N important conference on education in 

 forestry will be held in New Haven on 

 December 17 and 18 of the present year. 

 The work of the conference will take the 

 form of reports from a number of com- 

 mittees, each reporting on a certain phase 

 of the subject. The entire subject will be 

 covered by the various committees who are 

 now working on their reports. All fores- 

 ters and employers of foresters interested 

 in this subject and who can arrange to do 

 so, should attend the conference and parti- 

 cipate in its activities. 



FIGHTING THE BLISTER RUST 



"C 1 XPERIMEXTS in the warfare against 

 the white pine blister rust, which are 

 being carried on both in the east and in 

 the central west, begin to point the way 

 to better methods of attack. Such is the 

 report of E. G. Cheyney, head of the for- 



estry division of the Department of Agri- 

 culture, University of Minnesota. 



The white pine blister rust, like the black 

 stem rust of wheat, is kept alive and spread 

 by a plant ally of the disease. The group 

 of plants aiding the blister rust is known 

 as ribes and is made up of the various 

 species of currants and gooseberries. Spores 

 from diseased pines cannot carry to other 

 pines and infect them. The spores must 

 first find lodgment on a currant or goose- 

 berry bush and there develop a new spore. 

 This may then be carried to pine trees to 

 infect them. If, therefore, the ribes tribe 

 can be eradicated or greatly reduced, the 

 danger to the pine areas will be removed, 

 or at least greatly reduced. 



Understanding this situation, Mr. Cheyney 

 began at Rush Lake, Minnesota, a series of 

 eradication investigations. In the course 

 of these investigations in 1919, he uncovered 

 the important fact that instead of pulling 

 up the ribes. plants, the best method seem- 

 ed to be to grub them out. The reason 

 was, that in the work of eradication it was 

 found that neither from pulled nor grub- 

 bed plants did there spring any root sprouts 

 except where the root ends were exposed 

 to the light. The inference from this was 

 that the cutting off of the roots would seem 

 to be more effective than pulling, for ordi- 

 nary care would prevent leaving pieces of 

 crown in grubbing, while only extraordinary 

 care could prevent the leaving of exposed 

 root ends after pulling. It is believed that 

 the discovery of this fact will simplify, to 

 some extent at least, the problem of eradi- 

 cation. 



If, then, a high degree of efficiency in 

 eradication can be maintained, the re- 

 sprouting can be eliminated by improved 

 methods, "the reduced leaf surface of 

 the ribes crew of plants should certainly 

 give a large measure of protection to white 

 pine, if not complete exemption, from the 

 disease." 



OREGON AGRICULTURAL COLLEGE 

 pROFESSOR W. J. CHAMBERLIN, 

 of the Department of Entomology, 

 Oregon Agricultural College, has for two 

 months been studying extent of insect in- 

 festations in yellow pine and means for 

 their control. His field of operations is 

 southern Oregon. 



Special areas have been examined and 

 sample plots cruised in several instances 

 and breeding experiments for parasites 

 which will prey on destructive beetles are 

 under way. Professor Chamberlin has also 

 collected some valuable data regarding na- 

 tural enemies of the dendroctonus beetles. 



Experiments looking to possibility of de- 

 stroying beetles by use of electricity are 

 being started and a demonstration on a 

 scale sufficiently extensive to indicate the 

 merits of this means of attack will shortly 

 be undertaken. Up to the present time the 

 only successful means for destroying the 

 immature beetles has been peeling and 

 burning the bark of infested trees. This is 

 a slow and costly process.
