The Hamilton Spectator tells a rather unfavorable story concerning Phillip's Fire Anni- hilator. The facts, as narrated by the Spectator are,-that in consequence of a fire w hich broke out on board of the steamship Severn, in August last, during her homgward voyage from the Brazils, the Director of the Royal Mail Packet Company, besides taking other precautions to guard against the awful calamity ot fire at sea, ordered a supply of Phillip's patent fire annihilators to be provided for each of their ships. Two were accordingly put on board the Severn, and were kept ready for use. On the outward voyage, we are informed that one of these machines suddenly ignited, and the plug blew out, sending forth such a volume of flame and vapor as was excsudiiigiy diffieuH to subdue. Water wmthrown-upon the machine, but it:- only seemed to increase the offensive fumes, without decreasing the flames, The deck of the vessel was much burnt, and some little damage was done before the fire could be got under, Taking all the circumstances into account, the Severn had a second narrow escape from destruction by .fire, inasmuch as if the annihilators had been kept in the store room, (which might have been presumed to be a very natural and suitable part of the ship for their safe keeping,) another and fearful addition to the loss of the Amazon would in all probability have resulted,- If this account be true, as we see no reason to doubt, the annihilators should have their' name changed at once. Well Sinking—Artesian Wells. (Conti nued from page 112) Figures 1 and 2, in this plate, exhibit a spring rymfer, the cutting edges are placed re versely, and the size is regulated by means of the screw and the swivel. This tool is for enlarging the hole. When the pipes are inserted some distance, it is important that the bore under them should be so far widened as to allow the pipes to be driven further. This tool can be forced down the pipe in a partly collapsed state, springing to its set dimension, as the softer ground under the pipe is cut away. Figs. 3,4, 5, and 6 show a spring latch tool for raising broken rods ; the forked hinge, has a tendency to shut by the action of the spring ; therefore, when the tool is forced, over the knob of the broken rod, as represented . in fig. 6, the. spring s huts the forked hinge under the knob, by which the broken rod can be raised. Fig. 7 is a spiral instrument, something like a cork-screw; this is used for the same purpose, when the knob on the rod cannot be easily seized, or when the knob on the weight to be raised will not over come the friction of the screw. A tool, fashioned like a common lifting pump, is often used for very soft mud—a vertical up and down motion filling the body of the tool with the soft matter. Another useful tool for boring hard substances is a spiral winding round a hollow cone. As the boring goes on the material accumulates in this cone, and maybe thus raised to the mouth ot the well. Many other tools may be used, and circumstances may require the adaptation of a new tool'for a specific purpose in boring. Thus, in boring for the foundation seats of the cast-iron fire- tower in this city,-it becamd neeessary to widen the holes at the bottom, in the rock ;— this was accomplished by one of the most simple and unique tools we ever saw, which was invented on the moment for that specific object, by Mr. Bogardus—the designer and builder of the tower. It consists of two pecUliar-edged claws on one axis., which draw up 'together, but when dropped down, spread out and excavate a wider hole than that of the general bore. In England a patent was taken out, two years ago, for enlarging a bore at the bottom, for blasting, by employing acid to disintegrate the rock ; this plan is troublesome and expensive, because all the acid has to be washed and dried out before the blast is packed; the tool we, speak of accomplishes the same object mechanically, with less trouble and at less expense. Since we penned our last article on this subject the Williamsburgh Water Co. has, it is publicly reported, purchased two ponds of fresh water, at some distance from that city, and this haa been done although it had been asserted that a plentiful supply could be and was obtained from the boiling springs, where they have excavated in the lower part of the city. This shows that feus we entertained of future supplies from underground, as the heights of the city came to be occupied by houses. As all under-ground springs are obtained from water falling from the atmosphere, it follows that a plentiful supply can always be obtained by collecting that which falls in showers. In the latitude of New York, as much water falls every year, in a space of thirty feet square, as will supply an ordinary family. For manufacturing purposes the supply has to be very great, hence factories are al ways situated on the banks of streams, large springs, or where water is brought from a great distance, as in New York, Boston, &c.
