▪ The Connecticut Agricultural Experiment Station in New Haven, established in 1875, is the oldest Experiment Station in the nation. Among the many contributions made by scientists at the Station, the development of hybrid corn by Donald F. Jones, and the discovery of vitamins by Thomas B. Osborne stand as hallmarks of science that have received much attention. Since the early 1920's, two issues have been studied in great detail at this Station; maintenance of soil fertility in New England's nutrient impoverished soil and disposal of agricultural and domestic wastes. Since the solutions to these problems are intertwined, the Station has been examining the time honored custom of returning wastes to soil to improve crop production. Even before the current rejuvenation of composting as an option in waste management, the Station expended considerable effort in composting research and its utilization in agriculture. This is a historical review of these efforts.

The objective of this study was to compare the inter- action between Frankia and vesicular-arbuscular mycorrhizae (VAM) on the growth response of Alnus acwninata H.B.K. seed- lings under three different phosphorus levels. Alnus acuminata seed- lings grown in sterile vermiculite, were inoculated with Frankia strain HFPArI3 and/or VAM (as Glomus inwa-radices) under three R. 0. Russo. J. C. Gordon and G. P.

Listed below are fifty specimens of rusts, representing nine genera and thirty species. These were collected by the writer on various travels (not collecting trips) outside of the New England states during the past two years. Specimens of all of these collections have been deposited in the Connecticut Agricultural Experiment Station Herbarium. In the spring and fall of 1925 the writer spent a few days in the Pocono Mountains, Matamoras, Pike County, Pennsyl? vania. Of the twenty-three collections made, the following rusts on the specific hosts are not listed in North American Flora
