. Circular. Insects. 12 Careful harvesting.—It is always advisable to gather the entire crop, leaving none on the ground, and either place the nuts in tight receptacles or fumigate with bisulphid of carbon before marketing. The grubs crawl out soon after the nuts have been gathered, and as they require considerable moisture they will die if confined in closed barrels or boxes. The trouble is that enough nuts are usually left in orchards or in adjoining wood or forest land to serve for the propaga- tion of the insects the following year.

The trouble is that enough nuts are usually left in orchards or in adjoining wood or forest land to serve for the propaga- tion of the insects the following year. In order to make the method of treatment here described thorough, it will be necessary to secure the cooperation of neighboring landowners wTho grow chestnuts for mar- ket and of all who OAvn woodland containing chestnut and chinquapin. The collection of remnants can be made by children or the unem- ployed. It is also profitable to allow hogs the run of the orchards to destroy what nuts remain after the crop has been harvested. In the mountainous sections of Virginia and Pennsylvania it is a common practice to fatten swine on the unpicked fallen nuts. Hogs fatten on nuts and acorns as well as on corn, and without expense to the grower. Cooperation.—The results of the observance of clean farming on the lines that have been indicated may not at once be apparent, but in course of time, if this work is systematically carried out by all grow- ers over a considerable territory, infestation will be very materially decreased. An important point is to ascertain howT far the insects fly. Their structure indicates that they are strong fliers and capable, with favoring winds, of migrating considerable distances; but under ordinary circumstances they probably do not fly many miles at a time or in a given year. The Pecan Weevil. (Balaninvs caryx Horn.) With the increase of pecan culture in our southern States frequent inquiry is made in regard to the cause of the holes in the nuts (fig. 10), and during 1903 and 1901 there were reports of great
