In her old trim she was one of the moet unfortunate vessels in the Ravy. Im launching she broke her back, and after » short service she came home and was repaired at a cost of $300,000 (her first cost was $500,000). She again made a short cruise, and $40,000 were cxpended upon her, and on her return from another short e¢ruise it was estimated that it would cost $160,000 to put ber im repair. it will cest to make her ap iron-clad about $450,000.

The Novelty Iron ‘Waiks bave the. ach for plating her, although she is under thé fiiperintendenoe of gevernment officials, She is clad with iron plates ranging from three and a half to four and a balf inches jn thickness, which extend four feet Delow low water line. She will have three tarrets, end located forward and ¢w@ abaft the centre of the vessel. These ‘turrets are ths Ericsson model, each having two fifteem-inch guns. She will also be pro- vided with » ram on her bow. The plates of the ram are four and a half inches thick and twenty feet Jong, giving her a wedge on her bow nine inches thick. ‘The turrets will be twenty-one feet im diameter, the plat, ing being eleven inches in thickuess. Bach plate for the turret is nine feet in length by forty inches in width. ‘Two courses of rivet holes are punched in each, and they are all bent cold, in a powerful hydraulic press. The bed Plate of the press is concave, while the top plate is con vex. The plate for the turret is placed between the beds, end when preperly adjusted the pump forces up three rams underneath, and the plate is redueed to the proper curve against the top block, or bed. ‘The plates for tne sides are bent in form to suit the side ef the vessel, and it requires a deat of time to at them. A plate of eleven and a half feet in length weighs ‘ebeut four thousand two hundred and ferty pounds. The plates for the ram each weigh over four tons. The engines of the vessel are the same as prepelied her when she was a wooden steam frigate. ‘The turrets will each carry one, if not two, fifteen-inch guns. She will be, no doubt, one of the most fermidable vessels ever built. Her speed will be about ten knots: and with her beavy armament she will provea terrible antagonist. THE STEVENS BATTERY. Mr. R. 1. Stevens commenced the building of this bat- tery some years ago, and until within two years the public were kept in ignorance of ite peeuliarities, which are many. Her hull in general features resembles that of an ocean steamer, having fine lines, &c. The government, after several careful surveys, condemned it; but Mr. F. A. Stevens is now engaged in Gtting her up. ‘The following are her principal dimensions:-- Length over all... Breadth of beats Depth to gun deck......- Minimum draught of water.

THB PASSAIC—THE NEW MONITOR BATTERIES. The success of the Monitor led the Navy Depart, ment to. contract with Captain Ericsson for eight of bis style of iron-clads. He has adhered, with some improved modification, to his original plans. Im the new Monitors the design of the construction ie to keep ‘the muzzle of the guy inside the turret, so that it is at ‘all times unexposed toa chance shot of the enemy, which might aisable it. The guns,only twe in aumber, it is highly essential to keep in good order, and the resuit of their success may be looked opon as another grand triumph of the skill of Capt, Ericsson. A decription of one of these vessels will suffice for the outire number. As the Passaic was the frat launched, we give the particuiars of her dimensions, &c.:— Length over wll. Depth of vold Draught of wat Launching drat The form of this vessel is not unlike the Moniter.er eopting that her lines are fier, giving more speed and greater buoyancy. ‘The iron hull ws built of three-fourths iuch irom plating, fastened on toa frame of angle iron, stz inches wide by three-quarters of an inch thick. From & point three ana a balf feet below the water line a shelf extends outward, on which rests the wooden backing for the armor plates. This is covered by Ove wrought | iron plates, each ome inch thick and five feet | long by five feet wide. Im addition to the armor plating, the Passaic has wrought tron stringers feur inches thick inserted wnder the plating for a distance of fifty feet from the bow, making the armor nitfe inches thick, and fiving this vessel immense power as aram. The deck beams are of oak, twelve by twelve inches in the cen. tre, and ten by twelve at each end. placed only ‘twenty-four inches apart. The deck is planked with pine seven inches wide by eight inches deep. The deck is flush, with a geatie slope upwards from the csptre. The hatches are wrought iron frames, let in fush with the depk, and in action they are closed with wrought tron covers, which are securely fastened from below. The deadlights in the deck which light up the lower deck are also fitted with covers, and fasten in the same manner as the covers. ‘rhe plating on the deck is composed of two plates ove inch in thickness, rendering ft bomb-proof. The turret is twenty-one feet in diameter and nine feet in length. It is consructed of eleven thicknesses of one-inch tron, and is pierced for two guns, which stand parallel with each other in the turret. The pilothouse is placed on top of the turret, and is eight inches in thickness, six feet in diameter, and six foot in length.

Her sides slope inward at anangle ef thirty-seven degrees, to sbed the enemy’s shot. ‘She is built of iron, and her armor extends nearly foor feet below the water line, the horizontal deck is five feet above the water line. Her propulsion power is furnished by two propellers and two engines of five hundred bherse power. The bull of the vessel is constructed of balf-incb rolled iron. She has three keelsoos running the whole length of the vessel, and two fore and aft bulkheads, leaving eb ach side a space and forming an inner skin, which would probably keep out the water im the event of the outer skin being pierced by chot. In addition te these she bas two bulkheads--one forward and one aft—which can be filled with water; so as to settle the vesse! down while in action. Theso can be filled in fifteen minutes and pumped out In forty minutes. In using the ram, should the vesse! be wrenched so as to cause leakage, the compartment al” Inded to would preserve the vessel from siukimg. The vessel is submerged one foot by ‘he appliance of these water tanks. ‘The turrets are immevable, tke gun revolving to the ‘three ports pierced in each turret. They weigh each forty tons, and are built of @ groundwork of half inch rolled plates, like the hull, covered with bars of iron four inches thick, standing edgeways, placed one and aauarter inches apart, the interstices being filled with yellow pine. Over all this are three plates, each five-cighths of an inch thick—the whole structure bolted together with one and one-eighth inch belts, with countersunk heads, one foot apart. The turrets, therefore, are six and a quarter inches thick. Each turret is to have three ports, with heavy shutters, working in two halves; one port on each side and one ferward and aft. Each turret will have an eleven- inch gun, carrying a one hundred and eighty pound shot. ‘These guns move on revolving slides, which are placed on ‘a floor twenty inches below the level of the deck, thus giving a greater height to the turrets, which are twenty feet in diameter at the base, fourteen feet at the top— being cone-shaped—and eight feet eight inches-high. ‘The turrets are additionally supported within by bars of five by ene inch iron set edgeways, fifteen inches apart; and the ports are made sufficiently large to give the guns ten degrees vertical and eight degrees lateral range. ‘The rudder and propeller are guarded by an everhang- ing structure and a wreught guard on the after part. This little verse! will carry one hundred men all told, and has capacity in her two magazines for two bundred eleven-inch shot, one hundred and fifty eleven-ineh shell, with shrap- nel and canister, smal! ammunition and powder in pro portion. She seems admirably calculated for river work, her light draft and easy guidance, by means of two pro- pellers, fitting her especially for intrieate navigation. Her builder is confident that, though in some respects novel in constraction, she will be found as ehot-proef and serviceable as any; and the care and completeness with which he bas applied every precaution, aod multiplied means for offence and defence, give hopes of a most ‘efficient boat. Mr. Whitnoy was one of the earliest to urge the propriety of building a shot-proof fleet, and his studies in the question, as well as his knewledge of the qualities of iron, give his opinions weight. ‘The ventilation of the vessel has becn carefully attended to, and the accommodation for the officers and crew wil; be of an excellent character. ‘Tn many points the details of this vessel are uew and interesting. For instance, she entire lower portion of the sides of the turrets can be thrown open to admit light and air, and, of course, to effect the expulsion of foul air; and, there being 3 passage on cach side of the vessel, commu. nicating from one turret to the other, « constant circula- tion of air is kept up without artificial means, although such means are provided, and which will, in the opinion of many, render the vessel, in point of ventilation, second to none. SE BRENTON, In the eariy part of the rebellion a fleet of gunboats was improvised from the best materials then at hand. Subse- quently severalof the most powerful of the Mississippi river oats were built up as iron-clac#. The Benton was among the number, and, as there were several of her class con structed, @ description of her will serve to give an idea of their pesuliar style. She was constructed of two hulls Joined together, 80 as te form a powerful Bull one bun- dred and eighty-six feet in length and seventy. four in breadth. These bulls wero sealed up inside with four. inch oak plank. She is divided into forty water-tight compartments, and the whole struetare plated over with balf-inch iron. The plating commences seme distance Delew the water line, The plates are bolted en and the bolt heads let into the iron so that a anot could not knock them off. ‘She draws about four fect of water. She bas, in addi. tien to her plating, e bomb-proof bew, and should the en- tire forward part of it be shet away she will etill and protection will be afforded to the forward gui crews. She bas four boilers, which, with her engine, are securely located below the gan deck.

The wheolhouses are shot-proof, being ‘covered over with heavy timber and heavily plated The gun deck i» seven feet four inches intongth. The sides of the vessel are sloped,inward, at an angle of forty- five degrees. Her armament consists of eighteen nine and eight inch guns.

The ribs to receive the sheeting for the sides are now being bent, and as soon as they pave been got in place the work will go ‘rapidly forward. It was first intended to make them of Tiron; but it was found impossible to bring it to ‘the proper shape, amd angle iron had to be sub- stituted. It is the intention to plate the bull with four. inch iron, we believe, two feet below the water line. The deck is'to be of wood, covered with iron, anda wil, toa certain extent, be bomb-proof. ‘The turret will also be of iron, six inches thick, with the pilothouse on the top, and carefully protected. Each boat will de prepelled by four engines, will carry two of the heaviest guna, and) when loaded and ready for action, wil) not draw more than five feet of water. ‘The contractors are Messrs. Tomlinson, Hartutee & Co. ; but the work is being done under the superintendence of Mr. Easley, who has the reputation of being thoroughly fa- miliar with his business. It is the intention to have them ready for service by the Ist of February; but, looking at matters as they now stand, we doubt the ability of the contractors to finish them so soon. The turrets are being made at Tomlinson & Co.’s shop. These boats, as is evident from their builé, are intended wholly for river service. In connection with this article ‘we may state that the contract for a third Monitor bas been given out here, and arrangements for her construc- tion are now in progress. She will be two hundred and sixty feet in length by sixty feet breadth of beam, with eleven feet depth of hold, and will be far more powerful than either of those abovenoticed. THE DICTATOR. Captain Ericsson bas contracted with the government for two great sron-clad batteries and rams. They will bear a general resemblance to the Monitors. One of them is to bethree hundred and twenty feet in length, and the other three hundred and forty-one feet, eash with fifty feet beam. The vertical sides are <ix feet in depth, and are to be protected with irom armor, compozed of ‘wrought iron slabe and plates together, ten av: e- half inches in thickness, backed with four fect 0: lid oak, The turrets are to be absolutely invulnerabio—ile contract says two feet in thickness; but the contra! has permisaien to reduce the thickness, provided be satisfy the department that less will beeufficient. ii: ‘will be made sufficiently thick to withstand the four ac: dred and thirty pound balls of the Afteen-inch gun. These vessels will carry more propulsive power than any other vessels afloat. Each ship will have two engines of one hun- dred inches diameter of cylinder, with four feet stroue, and will make seveaty revolutions per minute: The doller surface will be 35,000 feet and 1,180 feet of grate surface. The boilers are a modification of Martin’s. The propellers are Ericsson’s, twenty-one and a half t diameter and thirty feet pitch. The contractors guar ‘& speed of sixteen knots per hour, or nearly nineteen n...cs, ‘We are not at liberty to describe the vessels at leugth, and refrain from giving the particulars of their armanent, which will be of a Kind yet unknown in modern warfare. It ia, however, as ramp these vessels are to be the most formidable. Where the plates and armor stringers meet ‘at the bow they form an irom wedge twenty-one inches thick at the base, and terminate in s sbarp edge. This wedge is sustained by the plates and stringers behiud it, ten ands half inches tp thickness, six feot in depth, extending the whole length of the vessel, forming the most powerful ram it is possible to conceive. There will be adifference in the armament of these vessels; but as it is yet deemed unwise we cannot give the facts. Suffice it to say that the Dictater will be a bost in herself, while the Puritan will be another. THE ONONDAGA, OR QUINTARD BATTERY. The Onondaga, in process of construction at the Con tinental Iron Works, Greenpoint, is a medification of the Ericsson batteries, being very buoyant and somewhat larger. She is of the following dimensions:——Length , 296 feet; beam, 48 feet; depth of hold, 18 feet. She will have two turrets, each twenty-one feet in diameter and nine feet high. She will be moved by one propeller and will have two powerfu! engines. STEAM SCREW RAM DUNDERBBRG. Almost every one has heara that Mr. W. H. Webb was about to construct a gigantic engine of war; but any- ‘thing deGinite in relation 60 her size has thus far been a profound mystery, tothe reading public at least. Already her large sides have become visibie over the fence around the yard where she is being built, but as yet mo one can obtain any idea of her appearance when Gnished. We do not prepose w give at this time avy particulars of thie craft whereby the enemy may be benefitted, but jn general terms and description give our readers on ides of her immense size and power. ‘The following are her principal dimenstome:— Extreme length, feet. eo ny 64 Whole depth .... + 32 Engines, horse power on 6,000 ‘The hull is built of wood, placed together so as to form a solid mass. The decks, sides and floor are also solid, and of & great thickness, so much so that if the Agures ‘Were given sil would be greatly surprised at the amount of weod used in the construction. This enormous wooden bull is beavily piated with rolied iron plates, which eover the entire upper portion of the vessel, and extend six feot below the water line. The weight of thie terrible armor is net far from-twelve hamdred tons. ‘The bow of the veusel, for fifty feet abaft the stem, is Of solid wood, with o@ space between the sides of the vessel, this being covered with ton, forming the mest gigantic ram on record, having unequalled in every respect. The above the water line, are seven feet thick and of solid wood, added to which is the beavy iron piating. This vensel bas two rudders, one at each end, so pro- tected that should oue become disabled from any eause the other cam be instantly used. ‘The engines will give this vessel a very high speed, se that when she strikes @ vesse! she would crash through hor with perfect ease, Above the main deck the build is very peculiar, but at present eannot be described. In addition to & iarge casemate, containing heavy broadside gans, there will be two of Kricasen’s revolving torrets, each containing two @tteen-inch guns. Tho naval register puts hor armament down as ten guns; but it will be much larger. ‘The accommodation for the officers and men are to bo oy ® superior Kind—large, airy and a9 well ventilated as an ordinary ovean steamer, yet giving to them all the neces. sary cecurity in time of action. t every respect she will be one of the wonders of the age. She fe intended more partioularly for arbor defences, ‘but can readily go to ses, as she possesses all the qualides- tions fer buoyancy, &e. ‘Scientific men who have seen her phas are unsaimows in thelr opinion of her success as s war voese), while Mr. ‘Webb's known ability as © shipbuilder gives at oncee of her future performances. She will be s most torriole affair, and will de@y anything olse in the shape of ee jron-clad, She is to be finished as soom an circum. stances @ill permit; and them, as fer ag New York harbor ie fe ‘concerned, we may net Rave any-feare- of tho vemete of amy country disturbing her. ‘THE WESTERN 1RON-CLADS. It is eb desirable at the present time to give aay eo tails im reference to the Western iron-clads, Thove (ine rebela) who are tho most anxious about them will ine out soon enough ax to how they are armed and beili. ‘They comprise a variety of forms, and are built axpresely for high speed and light draught of water, Some of thew will have turrets, while others will be casemated. The Western Tron-Olad Rams. THE INDIANOLA. ‘The Weetern waters require a somewhat different class of vessels, and in consequence vessels of light draught acé high speed have been built. ‘Tho Indianole is one ef the Rew class of gunboats andrams combined. She is armor- ed with three inshes of iron, securely fastened to ibe ‘wooden sides of the vessel, which are three feet in sbick- ness. The wheel, wheelhouse and roef aré boind-proot. ‘The quarters for the officers and men are not shiot-proot, and are liable to be damaged in siction, Her engines ore of four hendred horse power, and, with the Hoilers, sre well protested. She'draws vight feet of water. He cons is abont $25,000. ‘TER CHOCTAW. ‘The Choctaw is another of the same class, but, a2 the sketch shows, is of a different appearanes. She carries heavy armament, and with her high speed she is truly formidable craft, Sho is abontready, and will be at- tached to Admiral Porter’s Westora flotilla, which, for ef- fectiveness, wil) 20 doubt be one of the best of our squad” rons. OTHER TRON-OLADS. ‘The government have in contemplation other iron-ciads, which are for the present not named, or the contyacts awarded. A large number of plans have been subroitiee to the department for inspection, and it is not oniike ly some of them will be adopted. Aboutdwo thirds of the iron-clads in the following list will be provided with the Er icsson turrets.
