Abbott, Superintendent of the Botanic Gardens, entitled, "Notes on the Wild, or Canadian Rice." This paper was of a highly suggestive, and practical character, and the wish was expressed by several present that as much publicity as possible should be given to it. The Secretary read the following note from Mr. F. Abbott, junr., with the communication to which it refers from the Department of Agriculture, Washington, U.S.:— "The accompanying communication from the Chamber of Agriculture, Washington, relative to the Codling Moth, I received on Saturday last (9th August). No reference is made in it to any reports having been made by Commissioners or otherwise on the Moth, although I expressly asked for them, should there be any. The information supplied by the Department does not add much to our previous knowledge of this pest, but it confirms the fact of there being two generations in the year, and gives detailed instructions for the suppression of the Moth." Mr. Stephens read a paper on the same subject by Augustus Simson, Esq., of Gould's Country.
