INsECTARY: Three hundred and fourteen different experiments 
were carried on in the insectary during 1909. This number repre- 
sents a large series in connection with the clover seed insect, referred 
to above, and also the leaf hopper. There has also been insectary 
work with the Stalk Borer, several species of borers working on 
shade trees, and many insects have been reared from the larval 
to the perfect stage, thus giving us an opportunity of studying 
their life histories and determining their names. Two hundred and 
fourteen insectary experiments is the record for 1910, which really 
represent a much larger number included as “sub-experiments.” 
EXPERIMENTAL GARDEN: A piece of land granted the ento- 
mologist for experimental work, upon a part of which the insectary 
is located, has again demonstrated its usefulness, and the director 
and a committee for the purpose has allowed the entomologist some 
land adjoining the present site for future work. The entomologist 
has been promised sufficient land for experimentation, should the 
present garden be needed for building space. 
SPRAYING EXPERIMENTS: ‘The assistant entomologist, Prof. 
A. G. Ruggles, carried on in 1909 a number of experiments in 
spraying, and in summarizing the results of the work, it may be 
said with certainty that three sprayings for plums and apples, with 
three pounds of arsenate of lead in fifty gallons of Bordeaux mix- 
ture, the first spraying to take place before the fruit trees bloom, the 
second just after the bloom has fallen, and the third ten or twelve 
days later, will insure a very large per cent of sound fruit, protecting 
the fruit and the tree from the attacks of the Plum Curculio, Cod- 
ling Moth, and also a majority of plant diseases. See page 143. 
The crop of plums and of apples was practically a failure in 
Ig10, and we have, therefore, been unable to push work further in 
this direction. 
STATE INsEcTIcIDE Law: At the thirty-sixth session of the 
State Legislature a bill, (H. F. 173) for an act to prevent deception 
in the sale of Paris green and other insecticides, introduced by Mr. 
Horton, became a law. The enforcement of all provisions of the 
act was placed with the State Dairy and Food Commissioner. A 
federal law to the same effect, but including all states and terri- 
tories was created by Congress in the same year. The latter also 
imposes several penalties for the shipment of any adulterated insecti- 
cide or fungicide. See page Iot.
