It seems as though some kind of insect lays eggs on these geraniums and deforms the leaves. F. J. J.—Wis. Those light spots on your geranium loaves are caused by the cyclamen mite, Tarsonemus pallidus. To get rid of it, use nicotine oleate and spray thoroughly on the under side of the leaves, repeating at least once" each week until the plants are clean. Get from your druggist what is known as oleic acid and use it in connection with a forty per cent nicotine product. Mix two and one-half parts of the nicotine with one and three-quarter parts of the oleic acid. Then use these four and one-fourth parts in 900 parts of water.

If you find that you need a stronger solution, trv it out on a small scale first. A. F. J. Baur. GERANIUMS IN KANSAS.
