310 TRANSACTIONS OF THE HORTICULTURAL 



Our pupil may now be said to be prepared for good and 

 thorough high school work, in which the microscope must begin 

 to play its important part. Parallel to the high school work 

 in Botany and Zoology would come a course in Chemistry, in 

 which the poisons used in the battle against insects would be 

 studied and their method of application brought out. 



A pupil thus trained in his early years has powers of observa- 

 tion which is now almost unknown, even inside our college 

 walls, but can such training be done with the school divorced 

 from their natural companion, the garden? The schools need 

 the experimental garden. May the time soon come when it will 

 be truthfully said that the garden needs the school.

Prof. Forbes — Thought the paper a very good one and paid a 

 glowing tribute to W. C. Flagg; referred to him as being very 

 instrumental in the organization of the several Universities in 

 the several states of the United States, and that he was a horti- 

 culturist to whom we might all look back to with pride. Said he 

 thought by asking for the natural sciences to be taught in our 

 common schools we would get them, and that they were cer- 

 tainly worth the asking. He had always been successful in his 

 demands on the Legislature in that direction, generally getting 

 what he asked for. Anything that brought these matters up for 

 discussion before the people was a grand good thing. 



Mr. Hammond — Commended the paper very highly and con- 

 sidered that our common schools lacked the proper instruction 

 on horticultural subjects. 



President Bryant — Thought the subject of horticulture was 

 much neglected in our common schools, and that it should be 

 agitated and brought before the people for their consideration, 

 which, if properly done, something would be accomplished in 

 that direction. 



SYNOPSIS OF RECENT WORK WITH ARSENICAL INSECTICIDES. 



BY PKOF. S. A. FORBES. 



When, in 1885, I began work on the arsenical poisons for the 

 codling moth and curculios, these insecticides had been already 

 before the horticultural public for several years, but not a line had 

 been published in the nature of a full report of precise experi- 

 ments, and no one had as yet acted on the idea that elaborate and 

 exact experimentation was necessary. To throw some Paris Green
