THE WORK OF OUR EXPERIMENTAL GAR- 

 DEN AND INSEGTARY. 



The Legislature of 1905 allowed the Entomologist $2,500 for an 

 insectary, which is located about fifty yards southwest of the Mechani- 

 cal Building upon a piece of land, approximately a third of an acre, 

 granted by the Director of the Station in 1906 as experimental garden 

 for the use of this division. Previous to controlling a piece of land 

 we had been obliged to make use of fruit and other trees, shrubs, etc., 

 belonging to the Horticultural Division of the Experiment Station, 

 and as the entomological work sometimes conflicted with horticultural 

 observations, very naturally objections were made by that division, 

 which desired and needed all of its land for its own use. Now, with 

 the land granted for the purpose, the Entomologist has a small orchard, 

 berry bushes, and sufficient ground to plant grain in plots, as well 

 as various garden crops for the purpose of experimentation against 

 injurious insects. This experiment garden is proving extremely use- 

 ful. In it experiments have been conducted, and are now in progress 

 against insects afl:'ecting grain, cabbage, cauliflower, radishes and 

 tomatoes, orchard and nursery trees, flowering plants, etc. 



The accompaiiyin.g photographs give an idea of the appearance of 

 a part of this plot at the present time. In one of the cages shown, 

 closely safeguarded, so that it is impossible for them to spread, is 

 the much dreaded San Jose Scale, in an experiment planned to test its 

 ability to withstand Minnesota winters. In another cage an experi- 

 ment is under way with the Apple Leaf Hopper, and the land shown 

 staked (in cabbages and cauliflower last summer), is planted with a 

 large number and great variety of plants in an experiment against 

 the genus of Stalk Borers. This experiment may last three years, 

 at least two or three years will be necessary to obtain the economic 

 results which we seek. In every experiment station with which we 

 are acquainted the entomologist is allowed, as a rule, much more 

 ground than we have here for msect experiments. Our field experi- 

 ments this year against the IMum Curculio, and with dust and liquid 

 sprays were carried on upon ])lum trees and apple trees upon ground 

 belonging to the Horticultural Division, and upon a large commercial 

 orchard at Long Lake, and in experiments during 1906 and 1907
