Report of the Horticulturist 

To the Director of the Storrs Agricultural Experiment 
Station: 
Sir:—The investigation work of this departmént is of 
two distinct types :— 
1. Demonstration experiments. The object of this type of 
investigational work is to solve the various problems which 
confront the local horticulturist. Of such problems the fol- 
lowing have received attention. a 
(a) Orchard cover crops. Twenty-five different cover 
crops were tested in a tenacre peach orchard at South Glas 
tonbury. In order to verify the results of last year and to 
collect further information on the chemical composition of 
the plants used, it has been decided to repeat the experiment 
this year. | 
(b) Orchard renovation. The renovation of a badly neg- 
lected apple orchard is under observation. 
(c) Spraying experiments. Experiments in the spraying 
of melons, cucumbers, tomatoes, beans, etc., are being con- 
tinued. A comparative test was made of the commerciai 
miscible oils and a home-made preparation for the treatment 
of San Jose scale. The. home-made emulsion while ap- 
parently just as efficient may be prepared at one-third the 
cost of any one of the proprietary oils. 
(d) A new apple pest. Bulletin No. 45 gives the results 
of my observations on the habits and life history of the 
insect known as the Apple Leaf-Miner (Tischeria malifoliella 
Clemens. ) 3 
2. Research. Under this head comes the solution of the 
more difficult and fundamental problems in horticulture. 
Unlike demonstration work the aim of this type of investi-
