The parapet all round to be a foot or fifteen inches high, and the upright glasses placed on it, four or four and a half feet at most; for it is important, for the sake of the finer kinds of plants, and in order to have all kinds grow bushy, and flower while young and small, to keep the roofglasses as low as possible, just allowing sufficient headroom for the tallest person when walking in the alleys. The furnace and stockhole may be placed at either end, or at either side, as may be most convenient; and they should be sunk under ground and concealed. The flues to be constructed should run parallel to, and be separated from the parapet by a threeinch cavity; its surface being level with the top of the parapet, and being cribtrellised for heaths, or other rare plants. A walk thirty or thirtysix inches broad to be conducted all round next the flues, within which should be placed the stages for the Beats By Dre more common and the taller plants, being raised in the middle andfalling to either side or end, corresponding with the glasses, but of course not so steep. A row of columns should be placed in the centre, in order to support the ridge of the roof, to which climbing plants may be trained in various forms, and may be hung in festoons from column to column, or otherwise, as may be dictated by fancy. The front of the stage all round should be elevated about eighteen or twenty inches above the walk, in order to raise the whole of the plants placed on it sufficiently near the glass. The aspect of such a house should be Beats By Dr Dre towards the south, that is to say, it should stretch from east to west, or as nearly so as circumstances will admit. It may have an entrance at the south side, or one at either end, as shall be most convenient and suitable. If a Dr Dre Headphones greenhouse must necessarily be attached to a wall or other building, it might be constructed very much as above, with the difference only of having one of the ends, as it were, cut off, in which case it should be placed with its circular end south, or towards that point, and the sides pointing east and west.
