THE WEST SHORE September. 12 A COTTON-PICKING MACHINE. If tin' complex ojtcratinns needed in cotton plokluji tro loooutifiilljr pnrfnrnnil by mechan ism, it would seem that the inventor Deed brink from no problem. According to LtftU Millimj fftw$, the cotton picker bjM been patented and the following gives an idea of the machine and Uh task: Cotton plants vary in hight from one foot to seven, and are planted in rows at various diatances apart, hut averaging tOOttt three and a half feet. The podl mature at vary ing times, and when tliey open, the cotton grad ually unfolds ib i-Ii and hangs down more and more, until, if not picked, it is linally shaken out hy the wind, and falls on the ground. Thf picking season extends usually from the lattei part of Angnit to the linit of I)eceml)cr. From the knowledge of these facto Home idea tan he formed of the difficulties' t . he overcome hefore totton can 1 successfully picked by machinery. We now learn that an apparatus has been mudni'-ted and eTpenmented with wmcn UIIHIllW to fultill the requisite conditions.

It cm iisl i "i a frame, mounted on three wlicel.i, and Hpanning two rowtt of plants, the Mingle front wheel running between the rows, tho rear wheels outside. I he rear wheels are tjuitc largo, o an to carry the framework over the higliCBt plants; thu front wheel Ih much Hinaller, and works under the machine on a pivot joint, u which the liorHea are attached. The picking in done by a series of tlexibh rublier rods, licardcd with tine Hpinea point ing upward, which work alternately up and down tnroiign itic plants iu uiu mnnnntft snr ranees. These rods are foal i to levers, which vibrate alternately, ho that aa one rml is moving up the next ih going down.

The apparatus does not interfere with TO LOWBB THE TEMPERATUHE IN A SICK ROOM. Dr. Henry X. Dodge, of Morristown, givea the following to the Scientific A merkansA the result of his experience: A few weeks ago, while thinking with aome anxiety of the dangers which the ap proaching hot weather might bring to his toeth- hild. the idea occurred to tlie writer THE ORIGIN OF PETROLEUM. At a recent meeting of the Chemical Society of Si Petersberg, Professor Mendelijeff sought to combat some of the old notiona on the origin of petroleum, and to substitute a new theory on the subject It has been maintained by m&ny geologists that the decomposition of mineral that the temperature of a heated room might be miitter in the lower strata of the earth was the source oi petroleum. .xienueiijeu uence uiai, me true source is to lie found much lower down. The sandstone in which it is found were not its original sour as is shown from the fact that no carbonized an' imal remains are lounn in it. i Here ought also to be other products of animal decomposition, if that was the starting point; we must search lower down, even below the Silurian, as the mineral on m wiu v.aueiiMin in louim in the Tertiary, and in Pennsylvania in the Devonian and Silurian. As, however, in the rocks heln the Silurian there was verv little ureanie lifn the formation of such a great quantity of petro- iuuui wvum cv-j v-v-m w oui.u a liUllUxl source. Meudeliicti therefore oroiioses n mik stitute for the organic theory. He goes back to the nebular nypotiiesis ol Ijiplace, and applies inuetuiB ht i" u inigiiiui odvuub UOIlUlllon of the material of the earth, and, taking into consideration the density of the earth and 1 1-, vapor density of the elements, he arrives at the conclusion that the interior contains many met als, and that chief amoug them is iron; bnally, be assumes the presence of carburetic com pounds of the metals, and comes to the follow ing conclusions: Through some of the tissurea in the crust of the earth, occasioned by the upheaval and depression of the Burface, water percolated to the carbureted metals, and acted upon them at high temperature and elevated pressure, thuB forming metallic oxides and sat urated hydro-carbonB; the latter rose in ti, form of vapor to the upper strata, where they condensed to liquids in porous sandstones and Dther rocks having a tendency to absorb liquids. The internal heat of the earth occasioned thp reduction of carbureted metals, and this gave rise to hydro- carbons. Other chemists than MendelijetT have shown, experimentally, that something very like petroleum can be produced artificially by imitating in the laboratory the process above described. lowered by keeping the window aw nings satu rated with water or any voiatue uutu. Hy this means not only would the air which entered the windows be cooled by contact with the cool wet surface of the canvas, but also by evaporation of the moisture from the awnings. Accordingly, on the following day, a brass tube having a diameter of one-quarter of an inch w as so placed that it would lie across the outside surface of the awning at a distance of a few inches from the upper edge, which is attached by hooks and rings to the house. Tho ends of the tube, being bent at right angles to the tube, hang down by the sides of the awning about six inches. All along the aide of the tnbo which touched the awning were drilled, at intervals of three inches, holes about the size of a pin. One end of the brass tube was closed and over the other end was slipped a small indiarubber tube. This tube was carried in at the open window aud con nected by an ordinary screw coupliug to the near est cold water faucet The awnings of threo w indows of the nursery havingbteu supplied with this simple apparatus, the water was turned on, and, after passing through the rubber tubing, escaped through the perforations in tho metal tubes, and, llowmg evenly over the front and sideB of the awnings, dripped upon tho tin roof of the porch below the windows a miniature summer shower. In a Bhort time a refreshing coolness and moisture of the atmosphere re minded one of breezes blowing into the windows from off the surface of a lake. A thermometer hung outside of the window under the awning, while Btill dry.Bhowcd a temperature of 974" Eah. Upon turning the water on, the mercury sunk in If minutes to 00 Foh,, the thermometer still hanging below the awning, but protected from contact with the water. A still more marked effect might be produced by passing the rubber tulw through a pail of broken ice. The appara tus iH inexpensive; the amount of water used ia small, while the comfort which it might bring to a sick child or a feeble invalid might be very ia. that nfatht ls of value on thin aide of the the risiiu; or lowerini; of the awnini;: ondshnuld globe, as the U:mjcrature which calls forth the the dripping Ix; objectionable where there iB no remarks ia not higher than that of moat Amor-! roof below to receive it, a small gutter of canvas ieaii eitiea in midaumnier. The Cbineso prae- j or metal could be readily attached to the lower lice of rooting their streets in hot weather with ; edge of the awning to carry off the water; or a a temporary covering of matting is spoken of in m.,11 Mow of water may be used, enough only termaof hiidi approval. Streets thus shaded are Baid to furtiinh a moat agreeable arcade. It is further Hiiggeated that t he air lieneatb the matting might advantageoualv lie kept in mo tion by out-door punkaliH.

On FlUBt A writer for the Polytechnic. lie eiVir notes the following points: In using a new tile, the pressure employed at first should lie comparatively light, until the very Bharp edges of the teeth havo been removed; after which, stronger pressure aud deeper cut may bo made without injury to the teeth. Rut if the teeth have hard usage put upon them while their edges are keen and penotrating, they ore likely to take hold more strongly and liecome broken off at the root A few careless strokes may damage a new tile so as to take away half the "life of the first cutting. The lUni of cast ings are not only "chilled,'' ami hence harder than the interior, but are often glazed with a vitreous surface, in which, also, gritty particles are imbedded. No new file should be UBed on such surfaces, nor on welds where borax or vitreous tluxes have been used, nor on oxid ized Biirfaccs; but a worn file should be used to attack such work, which will scarcely harm it. For iilini: steel, grades coarser than second cut are apt to be too "hoggish;" steel cannot 1 ripped off like brass or iron, and the same cut of tile should not be used on steel and on iron, any more than on brass and iron, or horn and iron.
