"On the 19th of July last, Mr Crampton undertook to construct and lay down a cable containing four electric wires, each insulated in two coatings of gutta percha, and the whole protected by ten strands of galvanised iron wire, on or before the 30th of September. The electric wires, covered with gutta percha, in length a hundred miles, were turned out by Mr Statham, at the works of the Gutta Percha Company, and nothing can be more perfect than the manner in which that order was executed. The wire covering was ordered from Messrs Wilkins and Weatherly; but unfortunately, a dispute respecting the patent for making wire ropes occurred between that firm and Messrs Newall, which seriously delayed the progress of the work, as an injunction was served by the latter to prevent Messrs Wilkins and Co. from proceeding with the order.

"This was eventually compromised, and the rope was made conjointly by the workmen of the two firms on the premises of Messrs Wilkins and Weatherly, at Wapping.

"The very hurried manner in which (from this unforeseen delay) the work had to be accomplished, prevented that close attention that ought to have been given to any fracture, however small, of the wire; and in consequence, the outer casing, though of great strength and solidity, was not made with the same exquisite nicety and care that had been bestowed on the core of the cable."

The weather was unpropitious, and was probably the cause, from the circumstance of the Blazer being driven somewhat out of her course, that the length of the wire cable was not sufficient. This defect was, however, only of a temporary kind, and was supplied by that which was intended for another purpose. We extract the interesting account of the proceedings from the Times:—

"Shortly after 7 o'clock the fastenings at the end of the cable at the Foreland were completed, and the Fearless started to point out the exact course to be followed by the Blazer, which was towed by two tugs, one alongside, and the other ahead of her.

"A third tug belonging to the Government was also in attendance.

"The arrangements for paying out the cable consisted simply of a bar fixed transversely above the hold, over which the rope was drawn as it was uncoiled from below, and a series of breaks acting by levers fitted to the deck, in order to arrest the passage of the rope in the case of too rapid a delivery. On reaching the stem the cable passed overboard through a 'chock' of a semicircular shape, lined with iron. On starting, the steam-tugs proceeded at much too rapid a pace, (from four to five knots an hour,) and consequently one of the fractured wires (before alluded to) caught in the friction-blocks, and, before the way of the vessel could be checked, one strand of the iron wire was, for a length of about eighteen yards, stripped from the cable. The steam-tug towing ahead was then ordered alongside, when the speed could be better regulated, and the rate was reduced to about one and a half to two knots an hour. About six miles from shore it was determined to test the wires; but, from a misapprehension of instructions, the telegraph instruments at the South Foreland were not joined up with those on board the Blazer. A steam-tug, with one of the engineers and directors on board, immediately returned to the Foreland, when communication was made by telegraph and fusees fired from the vessel to the shore, and from the shore to the Blazer.

"At about mid-Channel, in the midst of a heavy sea, and a strong wind from the SW., an accident occurred, but for which the enterprise would have been carried out with the most perfect success; this was the snapping of the towrope (an eight-inch cable) and the consequent drifting of the Blazer from her appointed course to the length of a mile and a-half. Notwithstanding the delay caused by this untoward incident, the Blazer arrived off Sangatte at about 6 o'clock. The evening was, however, too far advanced, and the weather too stormy to attempt a landing; and, after embarking most of her passengers on board one of the steamers that ran into Calais, she was anchored for the night about two miles from the shore.

"On Friday the wind blew a strong gale from the westward, which rendered all near approach to the shore impracticable; but the Blazer was towed to within a mile of the beach, when, it being considered dangerous to leave her at anchor, the remainder of the rope was made fast to a buoy and hove overboard. The steam-tugs then returned with the Blazer to England.

"On Saturday the weather continued unfavourable, but Captain Bullock proceeded with the Fearless to the buoy off Sangatte, and, having hauled up the end of the rope, he towed it some hundred yards nearer the shore, and then again moored it.

"On Sunday the wind shifted more to the southward and moderated. Accordingly, the engineers and managers of the Gutta Percha Company took on board the Fearless a large coil of gutta percha roping, and, after hauling up the end of the telegraph cables, the first wires were carefully attached, and at half-past five in the afternoon a boat landed them on the beach at Sangatte. The moment chosen for landing was low-water, and the coil of gutta percha ropes was immediately buried in the beach by a gang of men in attendance, up to low-water mark, and even to a short distance beyond it. Thence to where the cable was moored did not much exceed a quarter of a mile.

"The telegraphs were instantly attached to the submarine wires, and all the instruments responded to the batteries from the opposite shore. At six o'clock messages were printed at Sangatte from the South Foreland, specimens of which Captain Bullock took over to Dover the same evening for the Queen and the Duke of Wellington.

"On Monday morning the wires at Sangatte were joined to those already laid down to Calais, and two of the instruments used by the French Government having been sent to the South Foreland, Paris was placed in immediate communication with the English Court."

We have remarked that very important discoveries are accidentally made in pursuing one of quite a different character from those which come up in the search unexpectedly.

They who remember our towns lighted with the old lamps, that in comparison with our gas-lights made but a "palpable obscure," should also remember how the change was brought about. The gas, which has proved of such vast utility that we can now-a-days scarcely conceive how the world could go on without it, was first a misfortune. It was generated in the coal mines, and, in order to get rid of it, it was conveyed by tubes to the outer air: in doing this it was found there to ignite, and from this simple attempt to effect an escape for a nuisance is almost every town in the civilised world illuminated by gas—besides which, the advantageous use of it in manufactories is beyond calculation. Even of gutta percha, now applied as a coating to these wires, who can determine all the uses to which it may be found applicable? Nature, it should seem, does not fabricate one material for itself, or for one use only, but adapts one thing to many purposes—and thus, as it were, teaches us that there is a chain in the facts of nature, by showing us a few of the connected links; and, at the same time, so far from exhibiting any sudden breaks, offering evidences of a continuous connection reaching beyond our conception. Verily this poor opaque earth of ours is the foundation on which the Jacob's ladder of invention is laid. We know not where it reaches, but there may be suggesting angels passing to and fro, and when their feet touch the ground, it delivers up its secrets, that float into the ears of the dreamer.

Electricity, it would appear, is the great agent in this connecting chain—nay, is it not, whatever it be in its essence, the chain itself, and the universal power equally in inert matter and in life? It has neither boundary on the earth nor in space. Its home is ubiquity; like the sphere of Hermes, its centre is everywhere, its circumference nowhere. That this astonishing power is yet under restraint—that it is not only kept from the evil it would do, but rendered to us serviceable—is a proof of the great beneficence of Him who made it and us. When the admiring child touches that gem, the dew-drop on the rose-leaf, it knows not that the little hand is on that which has lightning in it enough to cause instant death. It is scarcely the lover's poetical dream that he may be killed by the lightning of an eye—done dead by the tear that only moves his pity, on his mistress's eye-lid. In that little drop is the power of death—and by what miracle (truly all nature is miraculous) is the execution staid—the power forbidden to act? Nay, even the pity that we speak of, love itself, strange in its suddenness as we see it, how know we what of electricity be in it, instantly conveying from person to person natural but unknown sympathy?

Let us not get out of our depths,—but emerge from "the submarine," to land; and for this purpose, and to complete our argument of unexpected and collateral uses, we offer an extract from the Army and Navy Register:—

"New Mode of Discharging Gunpowder.—On Monday, August 18, some interesting experiments were tried at the Gutta Percha Company's Works, Warf Road, City Road, for the purposes of demonstrating the means by which this extraordinary production may be applied to the operation of discharging gunpowder. A galvanic battery was connected with upwards of 50 miles of copper wire covered with gutta percha, to the thickness of an ordinary black lead pencil. The wire, which was formed into coils, and which has been prepared for the projected submarine telegraph, was attached to a barge moored in the canal alongside the manufactory, the coils being so fixed together (although the greater portion of them were under water) as to present an uninterrupted communication with the battery to a distance limited at first to 57 miles, but afterwards extended to 70. A "cartridge" formed with a small hollow roof of gutta percha, charged with gunpowder, and having an intercommunicating wire attached, was then brought into contact with the electric current. The result was, that a spark was produced, which, igniting the gunpowder, caused an immediate explosion similar to that which would arise from the discharge of a small cannon. The same process was carried out in various ways, with a view of testing the efficient manner in which the gutta percha had been rendered impervious to wet, and in one instance the fusee or cartridge was placed under the water. In this case the efficiency of the insulation was equally well demonstrated by the explosion of the gunpowder at the moment the necessary "contact" was produced; and by way of showing the perfect insulation of the wire, an experiment was tried which resulted in the explosion of the fusee from the charge of electricity retained in the coils of wire, three seconds after contact with the battery had been broken. This feature in the experiment was especially interesting from the fact of its removing all difficulty and doubt as to whether the gutta percha would so far protect the wires as to preserve the current of electricity under the most disadvantageous circumstances. Another experiment was successfully tried by passing the electric current to its destination through the human body. Mr C. J. Wollaston, civil engineer, volunteered to form part of the circuit by holding the ends of 35 miles of the wire in each hand. The wire from the battery was brought to one end of the entire length of 70 miles, and instant explosion of the cartridge took place at the other end. The experiments were altogether perfectly successful, as showing beyond all question that the properties of gutta percha and electricity combined are yet to be devoted to other purposes than that of establishing a submarine telegraph. The blasting of a rock, the destruction of a fortification, and other operations which require the agency of gunpowder, have often been attended with considerable danger and trouble, besides involving large outlays of money; but it may be truly said that the employment of electricity in the manner described is calculated to render such operations comparatively free from difficulty. Amongst the company present on this occasion was Major-General Sir Charles Pasley, who took a warm interest in the proceedings, and expressed himself much gratified at the result. It is impossible to foretell the value of this discovery, particularly in engineering and mining operations. It forms a valuable addition to the benefits already conferred upon the public by the enterprise of the Gutta Percha Company."

This extract may lead the reader to conclude that there are double and opposite purposes in the secrets of nature. The chain which was intended to connect all nations in a bond of peace, has, it should seem, also (incidental to the first discovery) its apparatus for war.

When his Grace the Archbishop of Canterbury was blessing the Crystal Palace, and all within it, as emblems of a religious bond of peace, and of amity of all nations, and it pleased the admiring masses to proclaim it the Temple of Peace and of Love, there was little thought that, among the machinery and instruments it contained, those of murderous purpose would be the first required for use, which was actually the case, when permission was asked and given for the removal of revolving firearms from the American department, to be sent out to the Cape.
