(316) TO ENGINEERS.-Subsoil Pulverizer.-A the undersigned for an approved draft design (accompanied by a written explanation) of a MACHINE, to consist of a series of augers, for the general pulverization, to a depth of 3 or 4 feet, of a marly soil, free from all obstructions but occasional small pieces of limestone; to be worked by a portable steam engine of 6 horse power, the augers to admit of expeditious liberation from the soil; but their number, shape, position (whether in one or two rows), and distance from each other, are matters left to the judgment of competitors. It is almost needless to add that no existing invention (Fowler's or any other) could effect so deep a pulverization as that considered essential to the efficient cultivation of the Vine in our Australian Colonies.

These Pumps are free from that liability to choke which is common to other Pumps, and their Working Parts are not susceptible of derangement either from wear or from being long out of use. They pass entirely through them, with ease, any substance that may 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, and 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 Fire Pumps, or be applied to the Washing of Decks; and their capability of Pumping from Several Compartments. Also, to their MARINE ENGINE-ROOM TELEGRAPHS, Which excelled all others in the recent series of Trials in Her Majesty's Navy at Sheerness. These invaluable instruments have been supplied and sent to almost all parts of the world, and in no case has there been any complaint of their working. Testimonials, bearing uniform evidence of the complete success of these Telegraphs, may be had upon application.

"The above engraving represents accurately a section of a leaden pipe, which was employed for a short time in conveying water from a well on the grounds of Mr. Dick, of Bonchurch, Isle of Wight. The water has cut these deep pits almost through the pipe, and not only upon the portion which we have illustrated, but has formed similar chasms throughout the entire length."-Erpositor. Poisoned Water Preventable. BY THE USE OF GUTTA PERCHA TUBING. The Gutta Percha Company have been favoured with the following letter, From Dr. MURRAY, Hull. "It is impossible to conceive of anything more injurious or destructive to the health of the community than the use 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, I have had the leaden pipe of my own house removed, and its place supplied with one of Gutta Percha. Nothing can be better. I have also recommended it to others, who have adopted the expedient. Resistance of Frost. The Gutta Percha Company have been favoured with the following Letters in reference to the non-conducting properties of Gutta Percha Tubing, in the resistance of Frost. From J. ARMSTRONG, Esq., M.D., Gravesend. "My private house, which was supplied with your Gutta Percha Tubing some five or six years ago, has never required the slightest attention; and previously, there was no winter passed that we were not deluged in coasequence of the bursting of the leaden pipes." From HENRY BROWN and SONS, Western Works, 108 Rockingham-street, Sheffield. "We have now a positive proof of the frost-resisting properties of the Gutta Percha Piping. On our premises we have a leaden Pipe and a Gutta Percha one lying side by side. The leaden one has been completely frozen up at least ten days, and the Gutta Percha one is still unaffected. NOTICES.

The Equilibrium Ball-Valve is simple and certain in its action, and is cheaper than the common cocks now in use. The Cottage Valves are suitable for application to any kind of basin; and, as they shut against the pressure, no concussion in the pipes can possibly occur. These cocks have been extensively and most successfully used in many towns, under continuous high pressure, varying from 100 to 350 feet; their efficiency and dura bility is, by experience, established.
