From Wilmer't Liverpool Scwi Lcittr. Thi Mnniter Gnu fbr the American Navr. The heavy piece of ordnance, ordered some time ago in this town to be made for the Princeton," United Slates steam Irignte, is now approaching completion ; and being the largest cannon ever made in this county, nnd requiring in its construction great skill and at tention to perfect it as solid mass, ,it has be come an object of considerable interest and cu riosity among nautical and scientific men. It will bo remembered that the. Princeton bad on board a gun of great weight and calibre, which, Inst year, burst on being fired, while litre party of American officers were present to view the vessel, by which several parties lost their lives, including tho Secretary ot Stute. his in lieu of the gun then destroyed, which vias of malleable iron, and made impeil'mily, of the same material, (requiring if well made, Joss bulk (or a given strength than cunt iron ) The gun was manufactured in the solid, by Mr. llorsfall at his "Mersey Stsel and Iron Works," and being of great length, and propor tionate thickness, the securely welding or con glomerating the whole from pieces into one e qual muss, before turning and boring, required the utmost effort of modern skill, and the aid of powerful machinery in heating and fashioning i. In the rough it was nenrly fourteen feet long, and little short of thirty inchen in diame ter at the thicker end. A round shaft of seven inches in diameter was first formed, nnd on this, is a foundation, were successively laminated wedges of iron placed longitudinnlly, on edge, end reversed in position so as to fit. These, placed round the original spindle., wtrc(as well as the shaft) brought to a white heat, and eecurely welded by a hammer, eipht tons in weight, worked by steam. Another layer, in like manner, was added over the former, and so on until the whole was of the requisite thick nuss throughout. When thus so far fashioned, and proved to be perfect and equal in all its parts, the mass a most creditable and, indeed, extraordinary specimen of forged srork was ec-nt to the works of Mesers. Fawcttt & Co , en gine makers and founders- The pun as sent to the foundry, weighed 11 tons 3cwt. 2qrs 11 lb. In the turning and boring it was reduced in weight about 3 tons 1 cwt. The length of the camion, now th-it it is turned and bored, is 13 feet, and the bore is 12 feet in length, and 12 inches in dhmcter, lea vinar a thickness of solid metal of one foot at the breech. In form the piece is plain and unas suming in appearance, without raised mouldings and rins, (on tho French system,') the object being to attain the required strength at each point, without useless metal ; and the whole ta pering nearly equally from the breech, which in '27J inches in diameter, to the muzzle, which is 19 inches giving a thickness of metal to it ax a tube of 7J inches at the former, and 3J inches at the latter. The model fur this gun was made on an inch-and a-half scale. The turning and boring occupied over a space ot nearly three months, (hough the oper ation is by no means slow, considering the quan tity of metal to be cut away at a gradual and notions rate to prevent any imperfection. The first drill introduced was seven inches in diameter ; and about a foot from it, a 10 inch boring head followed on the same shaft, making a bore of ten inches at once. An 11 j inch dril ling was next used, and finally one of 12 inch es. Tho gun was finally adjusted in the lathe, wis turned, the borers being stationary. The finishing operation with the 12-inch drill took three successive days and nights, without inter cession, the engine being kept at work, lest by ceaaing even tor a short time the contraction or expansion of the iron might, from alternate heat and cold, prevent the production of the desired iriie.nes.s of the bore, or leave a mark. As it is, the bore is as fine and smooth as that of a first rate fowling piece ; and the interior of the gun is equally bright and even. Through the centre of the breech a Urge hole is ilnlled to admit a think bolt, with a large iiend, to bo counter sunk in the rounded cup or basin ot the hree:h w here the charge will be , deposited. This bolt terminates exteriorly in a t-trong screw, upon which will be secured the outer or terminating breech piece ss a finish ; and this pin is so pis-five at the head, and will bo so cloxely fitted, that it will become part and pjreel of the gun, and cannot be blown out by any explosion which the piece will bear. In looking through lire hole (now open) the whole resembles a huge telescope. The piece will be poised on its carriage on strong trunnions of M inches long, forged upon a masssve iron belt or ring- encircling the gun I lie but it IIJ inches m l a 'a jsi aijggg? - .mi.

Among them were 33 "rpnng tW nneff," 28 "pendulum balances," 0 models with connected or attached weights. 5 model balan ces which require the use of fluids, mercury, spi rits and water, and a number of common balan ces called the 'trip scales.' They have adopted the Roman balance. The Committe say: "We are of the opinion that the common bal ance, called the 'Unman balance.' is the best adap ted to the particular pin pose and service in view. Among the number of 'samples' which we find constructed on this principle, the one which we think the most eligible, is that marked No. 20, (S. H. & Davis,) having a single sliding weight (not suspended) on a brass beam, turning on bar- denr-d points, the Weieht falling into half-onnee notches, with an onen scale (or dish) above. We suggest tbut the figures, to indicate the ounces, should be made larger and plainer on the beam. Of the other eligible models on this principle, the next, in our estimation, is that marked No. 88, (Fairbank's patent ;) to which may be added No. 8, (Benjamin Morrison) both of which ueem un wieldy j and in the latter, the adjusting weight at the end of the beam is objectionable for the service in view." tE?"WE perceive that onrold friend, Col.

Advertiser says : "The Bishop was riding with Mr. Martindale and the Rev. Mr. Polles. in a two horse wagon. After they tiad stalled some person in the rear cracked a whip, and the horses became restive; one of them jumped violently, got astride of the pole of the wagon, and commenced kicking. The Bishop arose fiom his seat, and in the jar ring caused by the rapid speed of the horses he fell out and struck violently on his faee, cansine a severe concussion of the brain. He was taken up entirely senseless and conveyed to the near est house, where everything possible will be done to restore him." Bv later intelligence we learn that he remain ed insensible till Saturday morning, when rea son aeain partially resumed her empire, and strong hopes are now entertained of his ultimate restoration to health and usefulness although he is still in a very critical situation. Schuylkill Nas-lgatUn. From the subjoined communication, copied from the North American of Thursday, our read ers will see that the Schuylkill Navigation Com pany are prosecuting the important work of en larging their canal, with a vigor which promises a speedy and successful completion of it : The Managers of the Schuylkill Navigation Company have determined to have the new large locks, eighty in number, between Phila. and Port Carbon, con pletcd by the first of April next. Arrangements have been made for the funds required to complete the work, and propo sals have been received from numerous contrac tors, some of whom have recently completed contracts on the F.rie Kxtension Canal, and o tbers upon the enlargement of the Wclland Canal in Canada. The bidding has been very animated, and the number of experienced ond rerponsible contrac tors, proposing at prices nenrly similar, bos been so great as to render the task of allotting the work somewhat difficult. The board ofMana gers, at their meeting on Tuesday, allotted near ly all the locks to good men, at prices in no case exceeding the Engineer's estimates, and general ly from ten to twenty percent, below them. The work will be immediately begun, and vi gorously pushed, without interfering with the use of the existing navigation. The payments will be made monthly, in cash, reserving fifteen per cent, to insure the fulfilment of each contract; which retained per centage, when the work is done, is to be paid either in cash or in six per cent, bonds, at par, at the option of the Compa ny. The completion of the new locks will throw the Schuylkill open at once to large boats and boats from other canals, which have heretofore been shut out by the smallness of the lock cham bers. With the present depth of water, boats carrying 120 tons of coal can naviga'e the line, and as the depth will lie gradually increased to rive and a half and six feet, boats adapted to car ry 200 tons can be placed upon the line nxt sprineand get up to their maximum tonnage in another year. The importance of this improvement to Phi ladelphia, it is difficult to estimate. Furnaces and Factories are constantly multiplying upon the banks of the Schuylkill ; and at the present time, besides a heavy coal trade, the miscella neous tonnnee of other articles now carried on the Schuylkill Navigation, is about one thousand tons per day. lit'ur Its centre width, and I! in thickness, and will also be brightly polo-hod.

Itound thisa hoop or belt of iron will bo put 011 to fit fluidity, but not welded; and over thin in contracting will clip the nthfr so lifhtlv that the trunnion belt will become immoveable, or, as it were, in one unit with Dip (run, to resist all recoil or shock. tho euii itself not being weakened in the least decree by any drilling or perforation to secure the belt. Tho balls which this monster gun will curry will each be 1 1 inches in diumeter, a quarter of an inch binf e(t tor winlbore, and will each weigh in c&i-t iron lb., so that the piece is in reality u iHiunder." Itefoie deli very it will bo proved at ilmtle Bay, with a double charge of ruupowder (4- lbs.) and two bilK weighing (of courso altogether) 472 lbs. It will be covered durum the experiment with mats and sand, to avert the consequences of any uceident from disruption though this, from its admirublo ami scientific construction, is by no means to U apprehended.

Theodore Freliugbuysen in the chair. The Reverend nnd venerable Dr Beecher was present, and made several speeches warmly recommending the cause of foreign mis sions, as one of the most important dutiesof those engaged in the cause of religion. There were a number of speeches from tli Rev. Mr. Todd and others. The Rev. Mr. Hutchison, a returned missionary fiom India, after describing the con dition of the heathen and the cheering success of our foreign missions, very strikingly contrasted the stinted offerings of Christian w ith thoseof some heathen. One wea'lhy heathen, il is know n, gave $150,000 a year afterwards to the support of his idol temple, as long as he lived. Another gave, at one time, $1, 500,000 for the support of bis religion, which Mr. II. saw borne through the city, making betweeu thirty and forty cart loads of specie ? Our several hundred thousand professing Christians hardly gave for this object a single dollar a piece ! Correspondence of the "American." Shamokim, May 17, 1S15. II. B Masses, Esij. : I am frequently inter rogated, by letter, &c, relative to the localities of the Shamokin Furnace, Ore and Coal mines. I wish to inform them, and all others concerned, through your paper, that the Furnace is situated near the Danville & Pottsville Rail Road, and is of the largest size, and capable of making 100 tons per week. The mouth of the Coal veins, by which the Furnace is supplied, are about 4(1 feet from the bridge that leads to the tunnel head. The Ore mines, now opened, are from 40 to 100 perches from the. Furnace and within a few feet of the Rail Road that passes said Fur nace. The different veins are from 9 to 18 inch es thick. One drilt, or gangway, opens two veins of from 9 to 12 inches thick. Some of the veins are Kidney, some of Limestone, and others of a Red Sheir Ore, and some of them are consi dered good. There is any quantity of Bogg Ore in the neighborhood, of an excellent quality. It being of the same kind that was carted from this place to the Cattawissa and Esther Furnaces, previous to the discovery of the Bloomsburg Ore. I do believe that Iron can be made as cheap, if not cheaper, in Shamokin, than at any other place in this State. I am, with respect, S. JOHN.

The Washington Union announces the painful intelligence that Gen. Jackson's health is such as to excite fears that his life is drawing rapidly to a close. A letter has been received at Nashville, which says the impression of the General's n arest friends now is, that he cannot long survive. Symproms of dropsy have intervened. His legs areswol len from hif feet up to his abdomen, and his re spiration is feeble and difficult. His great mind and clear memory, however, remain perfectly un clouded. His every act and woid shows his pa tient resignation to the will of God. The letter says : "In his perfect resignation, he manifests all the meekness and humility of a true follower of the blessed Redeemer ; anil in his constant prayers he looksNip to God in confident assurance of sal vation through the atonement and mediation of the Saviour. Supplications to Heaven for bless ings oujiis country ami her institutions for the perpetuity of our constitution and liberties, civi and religious are continually mingled in all his prayers and in all hisserious conversations with his friends. Truly, when he departs, it will be the fall of a great man in Israel, and politically and in moral weight of character, it will be th loss to his country and to the world of the first and greatest n an now numbered among the living the greatest benefactor of his country now surviving." Mr. Blair received a few lines from the Gene ral, as late as the 7th, stating that he had at tempted to write to him ; but his great feeble ness had prevented his finishing his letter. La-si. .J. L. . il-i..MWBme' tl.il Later from Taaas. Galveston dates to the 8th inst., have been re ceived. Maior Done (son. the U. S. Charge, has returned to the U. States. Gen. Houston, with his wife and son, arrived at Gatveston on the 3d inst., from his farm on the Trinity. He proposed to visit the seat of Go vernment of Texas, and will then come at once to the United States, be being extremely solici tous to see Gen. Jackson once again before the death of the latter, which appears so imminent. He yields to annexation as a matter ol necessity, if not of choice. Mr. Wickliffe, the ex-Postmaster General, was at Galveston on the 7th inst. Commodore Moore hna involved himself in a controversy with Gen. Houston, and publishes an address to the people of Texas, in which be ex poses his grounds of dissatisfaction with the ex- President. He enclosed a copy of this address to the ex-president, threatening to fallow it up with other exposures, until he can receive per sonal satisfaction for the injuries which he thinks himself to have received. The Picayune says : "There is no limit to the enthusiasm of the people of Texas in regard to Annexation. The only trouble with them appears to be, whether to meet in Convention and forma Constitution for 'the State of Texas' prior or subsequent to the meeting of Congress. This is a fertile theme for the several editors. To show the disposition of the President of Texas, we make a short ex tract from the Morning Star of the 3d inst., pub- ished at Houston : 'We rejoice to say that we have the most po- sitive evidence that the President and a majority of the members of his Cabinet are anxious to act with the utmost harmony with the people, and will cordially co-operate with them in their ef forts to consummate this great measure at the earliest practicable period.' The Hon. F.. Allen, the acting Secretary of State, arrived at Houston on the 22d ult. The Telegraph assures lis that he is nn ardent friend of Annexation, and is desirous that 'the great measure should be consummated at the earl if -t practicable period.' The papers contain ample roports of public meetings declarative of the feelings of the peo ple in regard to annexation. There is no occa sion to give these reports, so nearly unanimous are the sentiments of the whole country. The Texans already retard themselves as part and parcel of the United States, and, pioud of the Union, are only impatient that any delays should be interposed to its completion. Even the pa pers oppo-ed to Annexation but insinuate their objections ; they s-e that it must take place, and refrain from any open resistance to it. If we can judge from the tone of the press, and from verbal -communications, not all the diplomatic resources of the world can sway at all the gene ral mind of Texas. The papers have some ru mors of disaffection to the Mexican Goxernment in some of her Northern Departments. The wish may be father to the thought' in this case We have probably as late advices here as to the movement of Cen. Arista as has been received in Texas." fXjThe narrative and report of Capt. Wilkes' exploring expedition, will be, although a highly interesting and useful work, a very expensive one tolhe government. The entire official pub lication, when completed, will embrace 24 vol umrs, nine of which are volumes of folio plates The cost and expenses for -publishing the whole work are estimated at $69,370, vis : narrative, 121,000; charts, $15,000; the remaining por tions occupying th residue. Oreoon Wheat There was left with us, says the Frederick Herald, a few heads of ' Ore gon Wheat," which were taken from Bloomfield farm, belongicg to Henry R. Smellier, Esq , near Middb town, Maryland. Said wheat was in bra I on the 28th of April. The gentleman who left it stated that it was the natural w heat of Oregon Territory, brought in by a missionary, and pre. sented to Gen. J. Hite, of Pennsylvania ; he sta ted that the natives told him that it bad been growing there spontaneously for a great many years. The Fsankino Privilege. During the dis cussion in favor of abolishing the franking pri vilece, it w as contended that meuibers of Con- gress had franked their shirts borne to be washed. The romance treated a smile, but it seems that nmethine like it has actually occurred. A Mr. Beach of Georgia, in debate, charged Mr. Gid dings of Ohio, with having franked "a calic frock," marked Pub. Doc. It turns out to have been E D. Potter who franked home the frock. The Postmaster says it was McNulty's frank, but the package wasdirected to Mrs. E. D Pot ter, and at the next mail some dry foods were frai.kcd in the same manner. Laroc Hail of Fish. The New Haven Courier states that the largest haul of white fish ever taken in that place was last Monday, when ffl(tn huwhrel ttiim-'and were taken. One mil lion is the largest number ever before taken at once in the harbor, and were taken last year at that place. The net used is three hundred and fifty rods long, and yet it was filled to overflow ing. So great was the rush of fish in a biwly from one extreme to the other of the net, that a bystander represents the noise to have been equal to that of a steamboat. At the rate they are sold. this haul would produce the snug little sum of 750 dollars. Strange Recognition. The Boston Times says a youeg gentleman in the public streets of that city clasped a young lady around thi waist, and uttering a cry of joy, printed several kisses upon her lips with the quickness of thought. On coming to an explanation, it was found that the young gentleman had mistaken the lady for her twin sister, w horn he was courting. The Timrs thinks it dangerous to marry a lady who has a twin sister, as a man might be kissing somebody else's wife when he thought he had his ow n. The labor of a single Locomotive is equal to that of 068 horses, according to statistics recent ly published. Trains of cars leave Boston and Albany every morning, each train carrying 100 tons of merchandize, running at an average rate of 13 miles an hour, or 100 miles a day, includ ir.g stoppages. A horse would carry 1200 lbs over the mountains 25 miles per day. Divide the load of this one Engine by 1,200, and the number of horses for 23 miles in a day is 161 Four times this number, or 668 could carry this load 100 miles each day. Hence the iron horse is every day, foul or fair, doing the work of 688 horses. Ledger. Slavery In the British West Initlrs. The "apprentice system," as the new species of slavery is called w hich the British have intio duced in the West Indies, is exciting much at tention, and calls for inquiry whether that go vernment is acting in good faith in its profes sions of a desire to suppress this horrible traffic. It seems that w hen a slaver is captured on th African coat by a British ship, she is taken to Sierra I.eone, the slaves are landed, and instead of being settled in the colony as formerly, are told that they must emigrate to the West Indies as "free laborers," to shift for themselves. they will consent to emigrate, the government will give them a passage gratis. If they refuse they must hire themselves out at Sierra Leone at four pence or seven pence a day, when they can find employment, which is seldom possible. Ithey try to reach their old homes, they have no means of supplying their wai.ts on the jour ney ; and if they escape the danger of being en slaved by the way, they have nothing to expect but to be sold by their old masters to the next slaver that arrives. They are virtually obliged to emigrate. Mr. Wise, in one of his despatches to our government, says : "I submit whether, under our treaty with Eng land, some inquiry should be made which will elicit information as to her mode of enslaving captured Africans in her colonies. Is it not, in fact, a part of the slave-trade to take them away from their own country without their consent, to bind them out undera system of apprenticeship Are proper steps taken to guard their identity. and to revent them from being enslaved for life? If they may be held in bondage for a term of five or ten years, why not for fifty or one hun dred years, or any period beyond the duration of human life ? It is openly avowed here, from various quarters, that many of these apprentices after being bound out, are reported to be dea l by their masters; their names are changed and flesh marks are taken out, and they are tramt formed into slaves for life. Has England, under her treaties with and pledges to the woild, right to carry on a system like this, which leads to the difect encouragement ofthe Jrade he pro fesses to suppress, and which, by fraud and cru eltv. increases its horrors, inhumanities and crimes T" The President's Appointments. The Washington Union, in answer to a cor respondent who uses partly the language of com plaint and perhaps of advice, on the dispensa tion of the executive patronage, and remarks, that there is "no possible way to rally the de mocratic party and keep them together, except the friends of all the presidential candidates are fairly and equally dealt by according to their political standing, recommendations and merit," says : "We speak advisedly, when we say that the President of the United States knows no cliques in the republican party ; that, in the dispensation ofthe public offices, be makes no discrimination among the friends of the late Presidential candi dates ; that, in giving or refusing office, be does not ask himself, nordo-s he ask others, 'whether fthis man was o friend of Mr. Von Buren,' or 'that a friend of Mr. Calhoun, or Mr. Cass, or Mr. Bu chanan.' In filling up vacancies, he takes care to put in Republicans who are amply qualified, according to the best lights which are present ed to his mind, to discharge its duties who 'are honest, capab'e, and faithful to the constitution.' He has enjoined the same course of action upon the members of his cabinet, and will take care to see, as far as possible, that this rule will be faithfully carried out by all the officers, whom he calls on to co operate with him in the public Si-rvicc. . He has already declared more than onee. that he himself will not be a candidate for a second term of office. He has authorized us to declare it asain in the Propctus which we have submitted to the nation, as the creed of our own faith, and the gui le of our own course. He does not, therefore, design to shape his admi nistration to assist any aspirant, or to make his appointments to promote his own re-election; but to carry out faithfully the powers which the people have placed in his hands." The Union says Mr. Polk may be deceived in some of bis appointments, but no one more rejrefs when nn unwise one is made. The Pre. sutent, it appears from the same article, devotes himself with the greatest assiduity to the pub lic business. He works from ten to twelve hours in every twenty-four ; holds two cabinets a week ; sees visitors two hours every dav. when the Cabinet is not employed. He is also in frequent communion with his Secretaries. His correspondence is very heavy. His care in looking over every letter which he receives is far from b-ing inconsiderable. Letters ot re commendation ore pouring in upon him in favor of applicants for office. The other dav he had to appoint four officers in one of our principal towns. For one of them there Were not less than thirteen candidates, each of them backed by numerous friends. The President had to wade through the budgets of letters which each one presented to his consideration. But foi the business habits which he brought to Washington, the Union says, it would scarcely be possible for him to discharge his duties as carefully and as conscientiously as he is now doing, w ithout serious injury to his constitution. ledger.
