THE PATENT PLUM-
BAGO CRUCIBLE COMPANY

having completed the enlargement of their premises, beg to call the attention of nil users nnd shippers of Melting Pots to the great superiority of the PATENT CRUCIBLES, which have been used during the last three years by some of the largest inciters in England and abroad. In addition to their capabilities of melting an average of from thirty-five to forty pourings, they are unaffected by change of temperature, never crack, but can he used till worn out, requiring only one annealing for several days' work, and become heated much more rapidly than ordinary pots, effecting thereby a saving of more than fifty per cent, in time, labour, fuel, and waste. The Patent Plumbago Crucible Company also manufacture and import clay crucibles, muffles, portable furnaces, sublimate pans and covers, glass-pots, alt descriptions of fire- standing goods, anu every requisite for the assayer and dentists. For Lists, Testimonials, &c, apply to Battersea Works, London, 8. W. 43

IMPOETANT TO Aanufactueers, MILL OWNERS, &c.

GUTTA PERCHA MILL BANDS.

THE GUTTA PERCHA COMPANY bet? to state that the increasing demand for the Gutta Percha Strapping for Driving-bands, Lathe-straps, ore, fully justifies the strong recommendations they have everywhere received.

Their durability and strength—permanent contractability and uniformity of substance—their non-susceptibility of injury from contact with oils, grease, acids, alkalies, or water—and the facility with which the only joint required can be made in hands "of from 21X1- to SOO feet long—render them superior to leather for almost all working purpose*, and decidedly more economical.

TESTIMONIALS.

IMPORTANT ANNUAL SAVING.

From TRUMAN, HANBURY, BUXTON, & Co., Brewery London. "In reply to your inquiry, we have much pleasure in bearing our testimony to the advantages, both as regards economy and saving of time, effected by the use of your Patent Gutta Percha Bands in lieu of Leather Straps. "The stoppage of one portion of our works through the failing of the leather strap used to be of daily occurrence—but with this annoyanoe we are now never troubled. We hare had these straps in operation for nearly, three years, and are assured by our Engineer that they effect a taking to us of at least Thirty Pounds a year.**

From JAMES ABERNETHY & Co., Fury Hill Foundry Aberdeen. "We have now had Gutta Percha Bands working here for three years. One of them has been driving the fan blast for our smith's shop for all that time, and for anything we see, may drive it as long again. The speed of the fan is but 1,200 per minute. We have used tbera with, complete satisfaction, driving circular saws, and in some cases where leather bands would have been quite inapplicable from damp. We have uniformly endeavoured to have the drums and pulleys so proportioned to the strain, as that there is no chance of the band slipping; and with this precaution, and taking caro in using cross bands that they do not rub, we are quite- satisfied that they are superior in every respect to leather— stronger at the same weight, and keeping quite straight in working— requiring no lacings, and very seldom any repairs."

POISONED WATER PREVENTABLE

BY THE USE'OF GUTTA PEBCHA TUBING.

The Gutta Percha Company hare heen favoured with tht following letter) From Dr. MURRAY, Hull. 11 It is impossible to conceive of anything more injurious or destructive to the health of the community than the ui e of leaden pipes for the conveyance of water. The poisonous salts of lead thereby communicated are most insidious and subtle. I hail with gratitude the substitution of Gutta Percha Tubing. 1 have had the leaden pipe of my own house removed, and its place supplied with one of Gutta Percha Tubing. Nothing can be better. I have also recommended it to others, who have adopted the expedient."

STEAM CULTIVATION.
CHANDLER AND OLIVER

HAVE much pleasure in being able to state that they are now prepared to execute orders for their
PATENT STEAM WINDING ENGINES AND PLOUGHS, for Cultivatinu Land by Steam. ... .

The WINDING TACKLE can be fitted to Engines of any maker, and the IUough can be made to take any kind of apparatus necessary for Cultivating the Soil, such as Scarrifier Tines or Broad Shares, &c. Any Engine now used by fwraers can be fitted with the Tackle. It. s light and simple, and an ordinary Farm Labourer can work it.

The Engine can be used for Thrashing without taking the Ploughing Tackle off, not requiring more than three or four horses to take it from place to place.

These Engines are very useful for Pile Driving or Drawinir Ballast up inclined planes; at the same time they can bo used for Pumping. Fanners will find them most useful for all purposes.

Messrs. CHANDLER and OLIVER ore prepared to rcceivo orders for separate Windlasses, which are light and simple, and generally useful.

They pass entirely through them, with ease, any substation that uriy enter the Suction Pipes. The Novelties in these Pumps are their adaptation to the varied duties of Ships' Pumps, the facilities they afford for Cleansing the Suction Pipes, acd for Sounding or Examining the Valves; the readiness with which they may be used for Ventilating the Bilge, or for acting as a Syphon either for Watering the Ship, or for extinguishing Accidental Fires on board: the rapidity with which they can be converted into i'ire Pumps, or be applied to the Washing of Decks; and their capability of Pumping from Several Compartments.
