This figure is a vertical section of a self-acting apparatus for feeding furnaces with fuel, secured by patent in England as the invention of W. Wright, of Newcastle-upon-Tyne, and described in the London Engineer. It is intended to supply fuel regularly to the fire, is especially designed for glass furnaces, and is operated by the draft of the furnace itself. A is the cone of the glass staek or house; U is furnished with a screw fan-wheel, B, set in the wall, and revolving horizontally in the stack. The bevel gear, C D, operated by the fan, gives motion to the shaft, E, on which are gears, F G, that give motion to the vertical shaft, H, the lower end of which has a worm wheel on it that meshes into another, If, on the outer end of the archimedean screw shaft, II, working in a round casing, the inner end of which opens into the passage, N, leading to the furnace, O. The fuel h carried up by an elevator, R Ii, which is also operated bytheshaft, E, through a worm gear, S, on its outer end meshing into a worm, T. The fuel is depositedby the buckets of the elevator into the receptacle, H, thence passes down the channel, P, into the case of M, and is conveyed forward to the furnace passage, N, by an archimedian screw. As the fan wheel, B, is operated by the draft of the furnace, it follows that after it has started, it will supply fuel when properly set for the purpose in quantities proportioned to the combustion, thus forming a constant supply. As there are quite a number of glassworks in our country, this is a subject for tlie consideration of those engaged in the glass business. The apparatus ia also applicable to other kinds of furnaces. "WHILE boring an artesian well at Lafayette, Ind., very recently, after penetrating to the depth of 21G feet, a subterranean stream was reached, which, in an incredible short time, filled the well to the top. The Courier says that "Arabs in the desert could not have been more delighted " than were the citizens of that city. This experiment of an artesian well was made at the expense of the county. Literary Notice NEW AMERICAN CYOLOP.SDIA, Vol. I. D. Appleton. &Con New York. The value of a really good cyclopaedia is inestimable, because it is the collection and condensation of the facts contained in many libraries, without the dressing and adornment with which the original authors thought proper to clothe them. A learned divine was once asked by a rich man, what was the use of a library containing so many books" for," continued the man of money, "you can never read them through." " Let me," said the divine, in reply, "let me ask you, what is the use of your dictionary ? you never readit through." " Oh ! the dictionaryis of great use." " Then sir." replied the other, " what the dictionary ia to you, my library is to me—a place of reference." This ia exactly the caee of cyclopaedic literature ; one does not expect ever to read a volume through, but it is necessary that almost eveiy person should have a copy on their shelves. Concerning the cyclopaedia we are now noticing, we have to remark that the first volume—the only one published—is aa near perfection as may be : and what is best of all in our opinion, it contains an index to' itself—a thing that has long been wanted. It promises to be bulky, but as it ia being issued in parts, there can be no inconvenience in that, because the price places it within the reach of everyone, and we should advise every one to take it, for we have no doubt that it will long remain a standard, and prove a lasting honor to George Ripley and Charles A. Dana, the painstaking, accurate and talented editors. We shall take occasion to give a more critical examination of this work as we receive the subsequent volumes.
