Mrs. M. "W., Quaker Hill, K. Y., asks: " Will you, or some of your readers of the Monthly, please give me a little information through its columns about the following plants: What are the requisites for success in starting the double Chinese Primrose from seed? What special treatment do the following plants require: Cape Jassamine, Eucharis Amazonica, fragrant- Olive, and Stephanotis floribunda? And is the Eucharis a bulb, and if so, when is the proper time to plant it? If it is not too much for anew subscriber to ask, I hope some one will give the proper mode of treat-ins; them and thus confer a great favor on me. Would also like to know the cause and remedy for the little black flies which infest the earth of window-plants".
