The Second Pan-American Scientific Congress was held in Washington, December 

 27, 1915, to Januarj' 8, 1916. One of its numerous sections was entitled "Conserva- 

 tion of Plant Life," and under this section there was one session in which papers were 

 presented bearing upon the general subject of quarantine, in which entomologists 

 were interested. Mr. Marlatt, Chan-man of the Federal Horticultural Board, and 

 Dr. L. O. Howard, Chief of the Bureau of Entomology, took part in this discussion. 



A community demonstration on methods of control of Scolytus quadrispinosus in 

 hickory, and Agrilus bilineatus in oak on Long Island is being made under the specific 

 direction of Dr. A. D. Hopkins, Bureau of Entomology; 942 infested hickories and 

 911 infested oaks, within an area of 1,200 acres and involving six estates, were marked 

 during the fall for treatment. At present the control work is being carried on by 

 owners with special energy. Both the marking and control work are under the 

 immediate supervision of the assistant in shade tree work, Mr. L. C. Griffith. 



The present regulations of the U. S. Department of Agriculture require that a 

 copy of every manuscript intended for publication outside of the Department be 

 submitted to the Assistant Secretary for filing in his office. It will save considerable 

 work and time if Department agents who submit manuscripts for publication outside 

 of the Department send in three copies, one to be filed in the office of the Assistant 

 Secretary, one to be sent to the publishers, and the third to be filed in the Bureau 

 with which they are connected. 



It has been observed by members of the Bureau of Entomology that the cabbage 

 looper {Autographa hrassicce) has different habits according to the region in which 

 it occurs, due doubtless to climate, heat and cold, and environment. This species 

 can be easily controlled in Tidewater, Va., but it is more difficult to destroy in the 

 Atlantic region of the North. There is no evidence that when this species occurs in 

 Tidewater, Va., it cannot be controlled by almost any spray since the conditions 

 there are quite favorable for infection by a bacterial disease. The combination of 

 the disease and poisons kills a high percentage of the larvae. 



Theodore Pergande, the oldest scientific assistant in point of continued service in 

 the Bureau of Entomology of the U. S. Department of Agriculture, died on March 

 23, in Washington, at the age of seventy-six. He was born in Germany; came to 

 America at the outbreak of the Civil War; served through the war in the northern 

 army, and later became assistant to the late C. V. Riley when the latter was state 

 entomologist of Missouri, coming with him to the Department of Agriculture at 

 Washington in June, 1878. He was a keen observer of the structure and habits 

 of insects, and was especially noted for his work on the Aphididae. — From Science 



According to the Experiment Station Record, four new entomological laboratories 

 were completed in Canada during the summer of 1915, located respectively at Annap- 

 olis Royal, N. S.; Fredericton, N. B.; Treesbank, Man.; and Lethbridge, Alb. The 

 laboratory at Fredericton is the most elaborate of these structures and is a two- 

 story and basement brick building 24 by 30 feet, located on the campus of the Uni- 

 ' varsity of New Brunswick. Its work has been especially directed toward the natural 

 control of insects, notably the brown-tail moth, tent caterpillar, spruce budworm, 

 and fall webworm. The laboratory at Annapolis Royal is a wooden one-story and 

 basement building, 26 feet square. It is located on the county school grounds and 

 is equipped with special reference to combatting the brown-tail moth and for studies
