SIXTHLY, The _French_ Stoves are much the same as the _Dutch_; and I am informed, that they have many from _Holland_ and _Germany_; but they have another Sort, which is the Mode at present; it resembles an old-fashion’d low Chest of Drawers with a flat Top, and has swelling or rising Mouldings on all Sides, which represent the Drawers: It is composed of several Pieces of burnt Earth, in the manner of our Earthen Ware, and is placed upon a Frame of Iron at Bottom, and all the Parts are luted together to complete the Body: It is likewise bound about with two Iron Belts to keep all tight, and has a little Door at one End like a _Dutch_ Stove, where the Fire is put into it; it projects into the Room some distance from the Chimney, and gives Heat from the four Sides as well as the Top; There is a Flue proceeds from the back Part, and an Iron Pipe fixed upon it, to reach the Chimney; which carries the Smoke up the Funnel, and the Chimney is closed up all round the Iron Pipe; it is on the same Principles as the _Dutch_ Stove, and is subject to many more Inconveniences, which are not necessary to be mentioned. SEVENTHLY, The _Pensilvanian_ Stove-Grate comes lastly to be considered, which is a curious Invention indeed, contrived about Twelve or Fourteen Years ago, and particularly described by Mr. _Franklin_ of _Philadelphia_, in a Treatise intitled, _An Account of the New-Invented_ Pensilvanian _Fire-Places_, _printed at_ Philadelphia _in_ 1744. I have lately examined one that was made in that Country, all of cast Iron, which I believe to be the only one in _England_; and at the same time I saw a perfect Model of it, which discovered the whole Work at one View. THIS Stove-Grate must infallibly cure most of the Inconveniences, with which the other sorts before-mentioned are attended, if the Smoke Passages can be kept clean. You have a full Sight of the Fire, nor does it lose any of the upright Heat, as in common Fire-Places, and smoky Chimnies will be often cured by it. This Stove has likewise the Advantage of a constant Supply of fresh Air, coming in warm through a Canal, in the Manner before described by Dr. _Desaguliers_, with this difference, that here the warm Air comes out on each Side of the Stove, and is better adapted to warm the lower Air of the Room, than if it came out higher in the Chimney.
