a short time since for the purpose of trial, and to test the disconnecting and reconnecting process, the invention of those gentlemen so celebrated for their improvements on the marine steam engine. A large company of upwards of 150 persons, including many distinguished naval officers, and some of the most scientific men of the day, attended the invitation of Messrs. Seaward, to witness this interesting experiment, the success of which is of such vast importance to steamers making long voyages, but particularly to armed vessels destined for cruizing or attending fleets, and taking every advantage of their sails to save fuel.
The motion of the vessel appeared to offer not the least impediment to the process, which was performed off Gravesend, to the satisfaction of the company, the engine being detached from the starboard paddlewheel in the short space of two minutes and a half, and connected again in the same time, after the interim of a quarter of an hour, during which the power of the two engines was applied to the larboard wheel.
Amongst the naval officers present, we noticed Admiral Sir Philip Durham, Sir William Symonds, surveyor of the navy, Captains Phipps Hornby, Lord Prudhoe, Jones, Smith, Evans, &c. At three o'clock the guests were invited by Messrs. Seaward to partake of an elegant dejeuner; after which several loyal and patriotic toasts were received with enthusiasm, the prelude and responses to which gave opportunity to the speakers to do justice to the Board of Admiralty, for the high slate of efficiency which the navy has at present attained, and also to Sir William Symonds for the great improvements he has effected in naval construction, not only as regards steam-vessels, but every class, from the first-rate to the packet-boat. Sir Philip Durham declared, in the course of his speech, that in the long experience of sixty-five years, he did not recollect a time when the fleet could be considered ia such an efficient condition as at the present moment, and confessed his astonishment at what had been accomplished with respect to the increase of our force within these two years.
We were gratified to perceive the estimation in which the many important improvements connected with steam navigation accomplished by Messrs. Seaward were held, by members of the naval profession, as well as the gentlemen present interested in shipping. As these improvements are much greater than is generally supposed, and independent of the disconnecting process, (itself a matter of no small consequence under certain circumstances,) we are but doing justice to the talent and indefatigable industry of Messrs. Seaward, in attempting a hasty description, the data of which our readers may receive as correct, and draw their deductions accordingly.
The following is a comparative scale of the capability of engines by different makers; and while they show the great superiority of Messrs. Seaward's productions, it is but justice to the other eminent engineers to stale, that they are also engaged in effecting improvements ou this very important point.
The three essentials in a steam-vessel of war are, 1st, capacity; 2d, power of locomotion for the greatest distance; 3d, security of the boilers and vital pari of the machinery from destruction by an enemy's missiles.
These items have never before been calculated and published, and they prove the great superiority of Messrs. Seaward's engines, principally owing to their compactness in occupying less space, as appears by the length of engine-room, the importance of which the reader will appreciate, when he is informed that every foot in length so gained affords stowage for fourteen tons of coals in vessels of the above class. The other advantages are, that the boilers and cylinders are below water, protected on each side by the coal, impenetrable to shot; and that the portion of the machinery above is jof wrought iron, and therefore not so liable to damage either from shot, or from concussion, striking the ground or a vessel, as would be the case with cast metal.
We give these hasty data, the importance of which our naval readers will readily appreciate; and we cannot conclude without congratulating the service in possessing the devoted ability of such talented engineers as Messrs. Seaward, who we are glad to perceive are engaged in completing two other vessels of the same class as the Styx. We may sum up their improvements as follows:—engines of 25 per cent, less weight,but of equal rated power to any other; engine-room 20 per cent, less length, affording this additional room for fuel; and last, but not least, 20 per cent, less cost; while the vessels can steam nearly double the distance of those fitted with other engines.—Naval and Military Gazette.
The Ardwell.—A suit for salvage, instituted by Lieutenant Percival, the commander, officers, and crew, consisting of 33 men of her Majesty's revenue-cutter Badger, against the Ardwell, found derelict in the north seas on the 26th of February last. The vessel had been sold, and the net proceeds amounted to 2971/. 4*. 3d. Dr. Lushington, would not give a moiety. The services were not long, nor the labour very severe, 125/. given as a fair distribution.
The Panda.*—A motion to decree to Captain Trotter, and the officers and crew of H. M. S. Curlew, certain bounties alleged to have accrued to them for the seizure of a number of pirates in the year 1833. The case to stand over, in order that the crown officers might have an opportunity of inspecting the'papers.
* See Nautical Magazine for 1837, p. 1.
The Eliza Francis.—In this case a bottomry bond had been given to Messrs. Montefiore and Co., of Port Jackson, for the sum of 1,055/. 7s. 2J. A primum decretum was prayed for, which the court granted.
The Harmony.—A commission of sale having been taken out against this Tessel, a sail-maker, who had possession of the sails, and on which he had a lien of 181/. 17*. S^jd., returned them to the vessel under a monition from the court, and now moved that the amount should be paid out of the proceeds of the ship. The court decreed payment, and also the costs.
The Choice.—This was an action entered by Messrs. Bell and Co., the prior mortgagers of a quarter of this vessel, against Messrs Smith and Co., the subsequent mortgagers of the other three-fourths, to recover the amount of their claim. The court dismissed the suit, and condemned Messrs. Bell and Co., in the costs. For judgment tee Shipping Gazelle, 1th Julg.
The Scotland.—A suit for salvage by the steam-vessels President, Albert, and Hero, for services rendered on the 16(h or 17th of November last, to the Scotland, when on the Jordan Flats, near Liverpool. A tender had been made of 250/. and rejected. The court awarded 400/. See Shipping Gazelle, 1th Julg.
Westminster.—This was a case of alleged salvage services rendered to this vessel, ofT Margate, from the 23d of November to the 1st of December last. The court awarded 1,500/.
Marie.—This was a case of salvage effected on the 6th of February last by three smacks—the Tiger, Rosabella, and Abeona; and the yawl Whim, off Harwich. A tender had been made of 50/. The court considered that sum insufficient, and awarded 80/. with costs.
'The Castor.—Salvage—A claim for remuneration for salvage services rendered by two fishing luggers, the Agenora and the Black Joke, to the brig Castor, which, on a voyage from Cuba to Swansea, with copper, having met with boisterous weather at the commencement, in January, reached the English coast in March, and was assisted by the two luggers (her own crew being in a state of exhaustion) into Plymouth. The value of the property was 5,300/. Dr. Lushington, was of opinion, thp.t although the service which lasted 11 hours, was not attended with any danger, and did not require severe labour or extraordinary skill, the vessel stood in need of the assistance afforded her. If the salvors asked 1,000/., it was an exorbitant demand, and he thought if he gave 200/. it was as much as they were entitled to.
The Helen Maria.—Salvage—An appeal from the award of the magistrates of Yarmouth, who had alloted a reward of 80/. to a steam-tug for towing the vessel (which had, through carelessness, run foul of the Newark light vessel, and thereby lost her mainmast) into Yarmouth-harbour. The salvors contended that, considering the value of the property (3,050/.), and that the magistrates had awarded the same sum to some boatmen from Winterton, who could render no effectual service, the sum of 80/. was inadequate.
Dr. Lushington was of opinion, that the magistrates had come to a just conclusion, and that there was no reason for the appeal. He affirmed the award with costs.
The Mary Ann.—salvage.— A claim on behalf of the Elizabeth, a small vessel of 28 tons, for remuneration for assistance rendered to the smack Mary Ann, from Shoreham, with a cargo of flints, which, in severe weather, she attempted to bring into Teignmouth, but the smack ran upon the Sprat-sand at the entrance, and sustained damages that reduced the value of the property to 121/. A tender of 5/. had been made, but the owners contended that the salvors had no cln'm at nil, though they had attempted to extort 100/. Dr. Lushington allotted 20/., with costs.
Armadillo.—In this case, Dr. Lushington pronounced against the bottomry bond, and condemned the party proceeding in costs.
Cato.—A suit for salvage services rendered to this vessel by the Tiger ami a number of pilots, on the 17th of January last, near the port of Sunderland. The court awarded 210/., one moiety to each set of salvors, the parties to pay their own costs.
The Florida.—Prize.—A Portuguese schooner was captured on the I3tl) of May, 1837, by her Majesty's brig Harpy, having on board 283 slaves. She was despatched to the island of Grenada, and, being found unseaworthy, was there sold under the superintendence of Peter Guthrie, the agent appointed to act on behalf of the salvors. The proceeds amounted to .'US'. 8*. \tl. The Florida had since been condemned by the Mixed Commission court; but Mr. Guthrie, notwithstanding repeated applications to remit the proceeds to this court, still retained possession thereof. The Queen's advocate prayed for a monition calling on Mr. Guthrie to transmit the amount to the Registry of the High Court of Admiralty. The court ordered the monition to issue, directing the sum to be paid to the Mixed Commission Court by whom the condemnation had taken place.
The Gamma.—Salvage.—A suit for salvage services rendered to this vessel on the 18th of Jaunaiy last, by six pilots, oil'the port of Sunderland. A tender had been made of 00/., which the court increased to 120/.—See Shipping Gazette, lOth July.
The Hope.—Salvage.—In this case 230/. had been awarded by the magistrates of Hull for salvage services rendered by the .Speedwell, and paid to the owner of that vessel. An action was now brought, on the 3d and 4tn Victoria, to compel its distribution by this court. The owner appeared under protest, and contended against the jurisdiction. The court upheld the protest.—See Shipping Gazette, 10//i July.
The Tyne.—Salvage.—This was a suit instituted by three steam-tugs, the Majestic, the Mary Ann, and the Ovington, for salvage services rendered to the Tyne, when grounded on a sand beach in Tyncmouth harbour, on the 1 1th of February. A tender had been made of 150 guineas, which the court overruled, and gave 250, with costs. See Shipping Gazette, lOlli July.
The Heart Of Oak.—Bottomry.—In this case, the brig Heart of Oak, in October, 1839, sailed from this country to Shippigan, in New Brunswick, where she arrived on the 14th of November. The master being without a letter of credit, in endeavouring to get a cargo of timber in time for the season, borrowed on personal security two sums amounting to 255/., for which he gave two sets of bills of exchange. The vessel being unable to get out before the ice set in, on the 22d of April, 1840, advices where received at Shippigan that the first set of bills was dishonoured, the property of the vessel having been, in the mean time, transferred to a new owner. The master was hereupon arrested, and whilst under restraint, though not in actual confinement, being unable to obtain his personal liberty, and the liberation of the vessel on any other terms, consented to give the party who had arrested him, a bottomry bond for the 255/. which had been secured by the bills, and also for a further sum of 413/. on account of the ship, the bond bearing a premium of 20 per cent. The validity of this bond was now in question.
Dr. Lushington pronounced for so much of the bond as covered money advanced subsequently to the 22nd of April; but he wished to mark his disapprobation of the conduct of the parties at New Brunswick, in taking n bond from the master under such circumstances, which justified the owners at home in investigating the matter, and he should, therefore, in pronouncing for the bond to the extent he had mentioned, give no costs.

The foregoing complete the long list of charts and plans resulting from the surveying voyage of H.M.S. Beagle, under Cant. R. Fitz Koy^and the Quarterly Review, in allusion to that voyage speaks thus:—
"Self-immolation is a term which we have more than once heard applied to the course pursued by those officers of the Britisli navy who have given themselves up to Nautical Surveying and discovery. If it is meant to convey the idea, that they thereby take a line, which under existing circumstances, leads them from the more substantial rewards of their noble profession, there is far too much ot truth in the expression; but if it be intended as an insinuation that such men are not employing themselves in the very best course of even mere professional training, we strenuously deny its applicability. If the perfect discipline and health of the crew, and their entire reliance on him who command* them; if the constant habit of manoeuvering the ship in all weathers, and in all situations; if a watchful preparation against surprise, whether from the elements or the wild races of men to whose shores she comes like some being of another world; if a steadiness of purpose and unconquerable spirit under circumstances' however adverse; if these be principles and qualities to insure victory in war, we know not where the country can look for them with more certainty than among this devoted class of seamen. Of the vast, the innumerable value of the services which able officers thus employed are in the meantime rendering to science, to commerce, to their country, and to the whole civilized world, we must say nothing—nothing we could say would be too much." Such were the men by whom the Beagle's work was done.
