at right angles to the sides of the dining-room win- 
dows, and the regular storm sash screwed on to 
these. Here were the three glass sides of a small 
conservatory. Half-inch boards made a bottom and 
roof, the former being supported by brackets to 
give strength, and the latter put on with two slant- 
ing side pieces nailed to the top of the upright nar- 
row sash spoken of, to give the roof a pitch. Top 
and bottom were covered with old flexible rubber 
matting which was carried back under the clapboards 
making a weather-proof, tight joint with the side 
of the house. Six-inch light wooden shelves on the 
inside gave a conservatory of considerable capacity. 
How many houses there are where some such ar- 
rangement could be made as the result of a few 
hours’ work and thought, and a very small expense. 
And yet how infrequently one sees anything of the 
kind. In many instances such a glassed-in window 
would be all that is needed, sufficient heat being 
furnished by a radiator under the window 
within the house. In the case mentioned, how-

house. This was done by installing a small gas 
stove in the cellar, as nearly as possible under 
the window greenhouse. Over this stove a large 
tin hood was fitted, with a sliding door in front to 
facilitate lighting and regulating the stove. From 
the hood a six-inch pipe, enclosed in a wood 
casing for insulation, ran through the cellar window
