Plants were taken from the strawberry bed and used for setting out a new bed, which is located on level and uniform ground. By another year sufficient data should be at hand to report on the performance of the varieties tested.
The aphids were very numerous and unfortunately caused the defoliation of all the currants with the exception of the blacks. A new sidewalk through the currant patch necessitated the transplanting of about one-half of the varieties, and so the prospect for a good currant crop next season is poor. The mildew attacked the Poorman gooseberry very severely but did practically no damage to the native varieties, as the Carrie and Houghton. Blight was a negligible factor, and what little appeared was removed as soon as noted. This year’s rest, especially as it has been coupled with a good growing season, should be very favorable for an abundant crop in 1916.
In summing up the varieties at the Trial Station, it is of interest to note that the following number are under observation: 235 apple, 1 apricot, 15 cherry, 3 peach, 6 pear, 70 plum, 23 blackberry, 3 dewberry, 14 red currant, 3 black currant, 2 white currant, 13 gooseberry, 26 grape, 4 black raspberry, 22 red raspberry, 1 purple raspberry and 157 strawberry.
Vegetables.—The vegetable work has been concentrated on the bean, cucumber, lettuce, pea, onion, potato and tomato. The chief work with the bean and pea has been to isolate desirable canning types from the present varieties. Selection has also been carried on with the lettuce, with the object of securing a head type which matures uniformly. Onion bulbs of various types have self-fertilized, and desirable fixed strains will be separated if possible. Incidentally, the inheritance of various types and colors of the onion is under observation. In the tomato the influence of crossing on yield and earliness has been studied. Increases nearly as high as five tons have been obtained, and the prospects are very bright for securing valuable combinations for gardeners who use greenhouses and high-priced land. Results of this work will probably soon be published in a station bulletin.

A better type of greenhouse cucumber is being sought by combining the European and White Spine varieties. From past experience the author knows that a uniform type that is well adapted to market purposes can be obtained, and the only question will be its productiveness. Unfortunately hybridizing was not performed early enough in the season, and disease prevented the making of crosses. This coming season the work will be repeated.
