HEATING BY HOT-AIR STOVES. 225 after being warmed by contact with the tubes, is distributed over the different portions of the house, being first com- pelled, under the striking-pit d, to form a bottom heat. By this extended radi- ating surface, which has also the advan- tage of being throughout its whole extent in immediate contact with the source of heat, the gardener has been enabled to obtain an invariable temperature with only two attendances daily. I bave," he says, " the satisfaction of adding, that this ventilating system of heating has proved uniformly favourable for plants in all stages, particularly when fruit is setting; and I have witnessed this pro- cess going on most successfully under the management above described, when the old plan of hot-water warming has not been able to produce the same result. The vapour appendage only now remains to be described : it is made of copper pipe, attached to the water-cistern, and resembles a fork with perforated prongs, through which water is made to drop at will upon the heated tubes, and may be so regulated as to continue imperceptibly saturating the atmosphere with moisture; or, by allowing a greater flow of water through the perforations, a steam is raised sufficiently dense to cloud the entire house in the course of a few minutes. Thus we have an unlimited power of producing artificial dew, which a consi- deration of the economy of nature shows to be largely required in hot climates, (else why so largely provided?) and while we strenuously endeavour to make an artificial tropic in our colder clime, we must not omit to imitate its insepar- able concomitantârefreshing ; Re- ferences to figs. â a stoke-hole ; b the chamber for the apparatus; k fire-box; c c hot-air drains; d striking pit, with bottom heat; e e ventilators ; / mouth of drain, h h for supplying fresh air; i the chimney; jj melon pits.
