The plants brought into the house in the Fall will perhaps begin to show signs of suffering soon, for insects, over-watering, and sulphurous gases soon begin to tell on the health of the plants. For insects, continual watchfulness, with a sponge and soapy water is one of the best preventatives; and to have plants rather underpot-ted is a good security against over-watering. By this we mean that the pot should be rather below than above the wants of the plants. As for sulphurous gases from heaters or burners, there is no remedy but to see that all is tight. People talk of dry air being injurious to plants, when they really mean impure air. Air is seldom too dry.
It is a pleasure to note that window gardening is growing in favor much more than many have an idea of. In a recent journey of some five thousand miles through our country, it was surprising how much of this kind of gardening was evident, over a few years ago. Pittsburg, Columbus, Cincinnati, St. Louis, Kansas City and Denver were generally gay with window flowers. Here, in Philadelphia, the number of people who have flowers about their houses is wonder-fully large to what it was over a half dozen years ago. Especially is this true of hotels and other public places. During the last annual exhibition of the Pennsylvania Horticultural Society, quite a number of persons went into the Hotel Lafayette, supposing from the large number of beautiful pot flowers about the hall-ways and windows it was the great horticultural exhibition. It is wise especially for hotels to pay attention to house gardening. Many people will travel in Summer who love country seats where they can have gardens and flowers, and nothing is more calculated to make these travelers feel at home than to have nice gardens and flowers for them.
