[Continued from page 47.] evidence in Oregon up to two years ago, but in this short time it has be- come a pest which must be cheeked. Prof. Lovitt described the life history and habits of the larvae and adults, showing that they breed in May and June, during a period of five or six weeks. The same generation thus ap- pears in all stages of development throughout the late spring, summer and early fall. Prof. Lovitt recommended spraying with nicotine solutions in the proportion of one to 400 parts, which he said had been used successfully in an ex- periment at an eastern college. Several members questioned the virtue of the spray so reduced in strength. One mem- ber advocated quassia chips and whale oil for outdoor use, but his experience did not cover plants under glass. Prof. Lovitt said the writer of the bulletin advocating the nicotine spray claimed that the one to 400 strength solution would penetrate the epidermis of the leaves and kill a large per cent of the larvae, which were feeding on the plants. The cyclamen grub has been giving trouble to the growers here for several years. The O. A. C. has been investi- gating methods of controlling it for two years. At present the college recom- mends sterilizing the soil by heat or chemicals, after the plants have been potted some time, as it is believed that while the eggs of the beetle forming the grub may be introduced with ma- nure, such introduction is not usual. J. H. Baehr read an article which he published recently* in the local dailies, calling attention to the fact that grow- ers of plants were longer-lived than other people, generally speaking, and that plants in the home, by giving warn- ing, by drooping, of unsanitary condi- tions, tend to conserve health.
