According to Science, Professor and Mrs. T. D. A. Cockerell of the University of 
Colorado will sail on June 4 from San Francisco for Yokohama. Thence they will

According to Science , Professor D. L. Van Dine, extension entomologist of the 
Pennsylvania State College, has been appointed one of the scientific trustees of the 
Tropical Plant Research Corporation, a newly formed organization, the objects of 
which are to promote research for the advancement of knowledge of the plants and 
crops of the tropics. 
Mr. W. E. Haley of the Bureau of Entomology has started experiments in southern 
Louisiana with the new hot water treatment of sugar cane. It has been found that 
soaking the cane in water heated to a certain degree destroys borers in the cane and 
at the same time hastens the germination of the stalks when planted. 
Dr. A. C. Baker will assist Dr. Quaintance in administrative work in the office of 
Fruit Insect Investigations, Bureau of Entomology. He will continue as custodian 
of the aphid and aleurodid collections, and will have time to pursue his studies in these 
families. A. C. Mason, under Dr. Baker’s supervision, will devote all his time to 
the aphididae. 
The results of the work of the Bureau of Entomology on insects affecting dairy 
cattle will be shown at the National Dairy Exhibit to be held at Syracuse, N. Y., 
next October. Practically every bureau in the department will have some part in the 
exhibit. It is expected that one booth will be devoted to entomological problems. 
Dr. L. O. Howard, who is now abroad, has been made honorary president of the 
International Conference of Phytopathologists and Economic Entomologists, which 
is to be held at Wageningen, Holland, on June 24. Dr. Howard will also attend the 
International Congress of Agriculture at Paris May 22-26, and the international 
conference concerning Dacus oleae, to he beld at Madrid on June 18.

The position of Assistant Professor of Beekeeping at the Massachusetts Agri¬ 
cultural College made vacant last fall by the resignation of Piofessor N. E. Phillips, 
has been filled by the appointment of Mr. Morton H. Cassidy, a graduate of the Col¬ 
lege who received his training in Beekeeping under Dr. B. N. Gates, and who has 
since that time been actively concerned himself, in Beekeeping. Prof. Cassidy 
began his work April 1. 
According to the Florists Exchange , the Colorado potato beetle has made its ap¬ 
pearance in France where nearly 100 square miles in the Bordeaux district are in¬ 
fested. Presumably it was carried from the United States to France in some kinds 
of produce, not necessarily potatoes. The British Government warns potato growers 
to watch for the pest and has prohibited the importation of plants and bulbs from 
the infested region in France.
