"W. M.," Govanstown, Md., writes: "I am in charge of a greenhouse on a gentleman's country place, size, 75x18 feet - glass area about 1,500 square feet - heated by one flue, running under front bench; in severe weather the thermometer goes as low as 450. It is a house of general utility for raising bedding plants, cut-flowers, etc., etc. I have been fairly successful with roses, such as Safrano, Niphetos, Pearl de J., and even Catharine Mermet, but I have a Mareschal Niel which bloomed well last June, then started growing in October and produced only about two dozen buds this winter, none of which were perfect, possibly because of too low temperature. It is now dormant and I expect it will produce a crop again about June. It is very strong growing, two seasons' growth covering 220 square feet. Now what I would like to know is, can M. Niel be grown successfully in such a house, and how can I change the habit of the plant, so as to make it produce the main crop during the winter months, instead of, as now, during the summer? I will be much obliged for the information".

[The Mareschal Niel is not now grown by florists for cut-flowers to the extent it used to be, partly on account of its waywardness as referred to by our correspondent, but chiefly because Perle des Jardins has become a successful rival. When it was popular, the season of flowering was regulated by pruning, the exact season for which depended on the amount of heat that could be commanded, aspect, slope of glass, and other circumstances. Taking the conditions as detailed by our correspondent, we think a severe pruning back to the two-year-old wood about the end of August, would bring winter flowers for him. - Ed. G. M].
