The moss and grass should always be returned in the boxes ; and, with a little addition, they will serve the ■whole season, provided such mate- rials be shaken up, and well aired, alter each journey ; in order that they may remain sweet. Lastly, it will be necessary to cord these boxes firmly, v.-ith a view to pre- vent any accidents that may arise daring their conveyance. If this method be carefiilly pursued, it will certainly be attended with success ; for, Mr. Forsyth observes, that fruit thus managed, may be sent vith perfe6t safety, either by coaches or waggons, tpthe remotest part of the kingdom. FURNACE.— The construaion of furnaces, so arranged as to ccn- spme the whole volume of smoke, is an obje6l which has long en- gaged the ingenuity of artists. — Hence various contrivances have been proposed ; but few, we be- lieve, for efficacy and simplicity, can come in competition with that invented by Messrs. Robertsons, of Glasgow. The opening of iheir furnaces, ins:ead x)f being closed by a door, consists of a quadrangu- lar hopper or fuiinelj hich is con- GOO tantly supplied with coals ; so that, in proportion as the fuel is exhausted, a fresh stock continu- ally descends through the hopper. Thus; the first combustion, which disengages the greatest part of the smoke and flame, takes place near the mouth of the fire-place, and a considerable quantity of the smoke will, without any other contriv- ance, be consumed by passing over the fed-hot fuel in the farther part of the furnace. But, as a perfe£t combustion of smoke can- not be obtained without the aid of atmospheric air, a cast-iron plate, about three quarters of an inch above the top of the hopper, is in- troduced, so that a slit is formed of this depth, and of an equal breadth to the front of the furnace; through which a current of air constantly enters, and is tiien com- bined with the smoke. This aper- ture may be enlarged, or diminish- ed, as occasion may requiie, by raising or lowering the iron plate, by means of an iron pin : thus, the supply of air may be proportioned to the quantity of smoke produced, and tie whole of the latter will be advantageously used, before it can escape through the chimney. G. Germ ANDER.— In the second volume of the "Travsafiiovsof the Jioi/til and Ecoiiomicul Society of I'loience," we meet with an in- teresting memoir by Dr. Menau- p.onk, on the medical properties of the Common Gekmakijer. Our limits permit us only to state, that Dr. M. strongly recommends the leaves and shoots of this indig( nous plant as a substitute for the Peru- vian bark ; a hint which deserves flie aitenliou of medical pradi- tioners.
