Whexi it is dark or the streets are muddy, or a crowd has collected on the spot before, the engines arrive,’ there is ge. nerally a good deal of difficulty in finding the plugs, and much time lost in conse:. quence. ‘I wouldthercfore propose that‘, ex. actly opposite to every fire plug, there should be a lamp, with a glass of pink color, so that the driver ofa fire engine might drive up to the very spot \ 'ithout the delay of a single in- stant. The cost ofsuch a lamp would be so trifling that I dare say that the fire companies would themselves defray it. - Your obedient servant, ‘WILLIAM Rump. 'Peterhofl', Jan. 10, 1833. On the Power 0 the ‘Wiml. By G. K. O. [For the Mechanics’ Magazine] SrR,—The wind is a natural agent, of much power, not often at rest, and accessible to any one, but is not applied to many me- chanical purposes, by reason of its extreme irregularity. It is the design of this article to suggest a method of obviating this diflicul- ty. Let a wind-mill. cause an air-tight &: 1 lbrcing-pump‘ to condense air in a suitable vessel : for instance, a steam boiler. If a cy- Iindrical vessel, ten feet in length and five in diameter, be thus made to sustain a pressure of 75 pounds on the inch, it will furnish 100 cubic inches per second of air of twice its ordinary density, for one hour, and exert force sufficient to raise 1000 pounds 450 feet, and, though unsupplied by the forcing- pump, at the end of the hour sustain a pres- sure of 30 pounds on an inch. The air may be applied directly to a wheel, or used as steam to work iin engine. The quantity emitted would of course be regulated by a governor, and a fly-wheel may be employed for further uniformity. The same object may be attained by caus. ing the wind, whenever it may blow, to raise water into a reservoir, whence it may be drawn at pleasure to work a wheel or by. draulic engine. One thousand cubic feet of water raised 25 feet, would, in descending, exert force sutlicient to raise 1000 pounds 1,562 5.10 feet high. Two heavy weights may also be employ- ed: ‘.37 cubictset of iron, specific gravity 7 5-10, descending 25 feet, exert t'orc"e sul’. ticient tor-aise 1000 pounds 316 4-10 feet. By means of double gearing one weight may be raised by the wind while the other is working, and when no work is doing, both may be raised. ‘.Vhatever advantages may attend these means ct‘ regulating the force of wind are obvious.

During the warm weather within the temperate, and at all seasons within the limits of the torrid zone, the fall of rain is often ac- companied by lightning, thunder, and violent winds, constituting what is commonly called a thunderstorm. Thunder-storms generally commence between mid-day and sun-set, and move from west to east.-——[Prof. Mitt-.hell.] S'rn.u1C.ian1Aoss AnnoAn.—-VVelearn, from a cor- respondent at Brussels, that KingLeopold is taking a very active part in the introduction of steam carri- ages into Belgium, which, being generallya flat country, is extremely well suited to vehicles of this description. His Majesty has appointed a commis- sion, consisting of Count Hompesch (president), Count Vilain XlV., M. Eagleo, banker, Colonel Schenofsky, and M. Jobard, manufacturer, to watch over the progress of this improved mode of trans. port, andto facilitate its general adoption by every possible means. The chief Belgian competitors in this line, at present, are M. Deitz, senior, (the in- ventot, we believe, of the steam-enginellately de- scribed in this .lournal,) and u M. Couchans, oi Charlerci, bothof whom have been making expori- mental trials, with carriages of their own construc. tion, in the neighborhood of Brussels. The carriage ct" Dcitz seems, from the description sent to us, to be rather a stupendous afi'air—eight tons weight, and fourteen feet high! It is hung, however, on springs —-—enormous steel springs (sur d’enormes 1'e.s‘8m'tS dmcier.) The boiler is composed of six elliptical chambers, placed in pairs one above the other, which contain altogether 240 square feet of licating surface; There» are two pistons, which turn two cranks, which turn two pullies,(which carry two endless chains, which turn the two hind wheels, by which (alone) the carriage is propelled. There is but one wheel in front, and that is used as a guide wheel. The engine is stated to be able, in ascend. ing hills, to exert a power of 120 horses, and there appears to be some arrangement by which in such cases the wheels may have the help of cogs (son! garnics de billets cle bois dc bout.) The river steam- carriage of M. Couchans has tour wheels. The cir- cumference of the wheels is stated to be “ elastic,” which means, we presume, that they are construct- ed on the give and take principle of our Messrs. Jones and Compan_v‘s'patent wheels. The results of experiments hitherto made’ with these carriages are but indiffererit. The greatest (speed realized is likened to the “galop (Pun bori cheval.” However, every new exhibition attracts “ une gtramle afiluence 1 r into Germany, which has since transferred the valuable trade in fine wool almost wholly from the Spanish to the German soil. From the pe- riod of its first introduction until, 1814, when ldiirope once more began to enjoy the bless- ings of a general peace, this wool was gradu- ally, although slowly, spreadingitself over the surface of the kingdom of Saxony; but when the continental trade was thrown quite open, by the events of the short -campaign of 1815,- and the minds of men were set at rest by the final catastrophe of‘ Napoleon, the Saxon wool dealers began to open a regular trade in the ar- ticle to England, and they soon discovered the real value of this new branch of German com- merce. In the first year, viz. : In 1814, there were imported into England only 3,593,146 pounds; in 1819, 4,557,933; in 1824, 15,432,657; in 1828, 23,110,882. This prodigious increase in the demand for German wool naturally excited the emulation of the States lying contiguous to Saxony; and the dock masters of that kingdom carried on, for a considerable period, a very prosperous trade in rams and ewes with the land owners of Si- lesia, Bohemia, Austria, and other parts, who were desirous of changing the nature of their flocks to this more profitable breed. All the superabundance of grain, which had no exter- nal vent to carry it off, was given to the slieep, in order, to accelerate their approach to the maximum degree of fineness of which their wool was susceptible; thus actually creating a profitable consumption for their corn, through the eagerness exhibited in England to obtain a superior quality of wool.-[Q,uar. .lournal.] To DESTROY VVooDLIcE.——Perhaps in cu- cumber or melonrframes nothing is more de- structive than woodlice._ Confining a toad in the frame or pit is an effectual remedy for the evil, but many persons would think the cure as bad as the disease itself, for they would be 1m. able to eat. the produce, from the recollection that the toad might have touched them. One method pursued with success is to make in the soil, close round the edges ofitlw frame, a. kind of hollow basin about six inches wide," and to fill this up with short hay to about the thickness of two inches. This, in the course of the first night, willbecome aplace of retreat for them, and at about nine or ten o’clock in the morning, having opened the frame, pour upon this hay, with a wide rose watering-pot, a con- siderable quantity of boiling water. Then re- move the hay and dead woodlice, and place a fresh supply of dry hay. Repeat -this opera- de curir:zt:2:,” and is concluded “an milieu. des braves de la foule,“ and at Brussels, as in London, nol doubt is entertained, by the generality ofpeop1c,that1 the day is close at. hand when steam carriages willl he the only vehicle in vogue on common roads.—— [Mechanics’ Maga7.inc.]. « . * _ . in on [From the New- Y ark Farmieix] BONE Du-sr AS:MANURE non TURNIPS.--Al’ though the quantity of bone dust usually ap- plied to an acre is two quarters, yet one quarter will suilice if mixed with one or two quarters of riddled coal ashes. Thefibones should be carefully and equally mixed throughout the mass, which will be best etfected by frequent turnings with the shovel. To expedite the dry- ing of the ashes, strmv a little hot lime, while tion for two or three days, and you will see no i more woodlice. Another System is to sink a pan half full of water in the soil, its rim being level with the surface, then to throw in a few . Slices of .ri )6 fruit, and lace a slate or iece of l _ pot over it, leaving only sufficient room for the entrance’ of the deprcdators. Examme this every. morning, anddestroy all such as are found therein. The pan may also be filled with hay and pieces of. fruit, such as apricot, doc. l)eJing laid in, they will quickly entice these dc. ,. predators.~ which on removing you may dc- stroy. Another very cil‘e.ctual method, is to slice the tuberous roots of the Bryony (brionia. dioica,) a well known plant, and very common in our hedges, and to put.a few-of, these slices into a common feeder, covering them ov or with a little moss or short hay, and placing them in tlitferent parts of the beds.
