[September, 



yl (\isl-lroii Lh-hl-iioiisc—Jhc necessity tor a lighthouse to I'acihtate the 

 navigation of the wind »ara passage by tho Morant point, in the island of 

 Jamaica, so as to enable vessids to avoid the Morant C'avs. a <langcroiis reel 

 of rorks, 25 milfs souiliwanl of that point, having' heen long felt hy the au- 

 fliorities of tlu' inland, tliey have determined upon the election ot a tower 

 and lights for that obicct, upon the rcnommendation and under the direction 

 of their consulting enginesr, Mr. Alexander (Jordon; and it may no.v he seen 

 in a very advanced state of forwardness, from the road at I'imUco, erecting 

 on the works of Charles Robinson, proprietor of the long-known cstaldish- 

 ment of Rramah and .Sons. It forms a most ccmspiciunis and nnposing object 

 as it rears its head above the surrounding buildings ; and when completed to 

 its full height, 100 feet, will doubtless attract much notice from its novelty. 

 The diameter of the base is 18* feet, tapering gradually to 11 feet under the 

 cap, which supports the lantern containing the lights and reflectors, which, 

 with the actuating apparatus for revolving the lights, arc constructing by 

 Deville, of the .Strand, 



The Dnj A"o/.— Government have recently ordered the opening of the fungus 

 pits in Woolwich dockyards, which bad been closed in August, 1836, for the 

 purpose of testing the 'virtues of Sir \V. Burnett's process for tendering wood, 

 cordage, and all descriptions of woollen free from the eflects, of dry rot. The 

 result, it «ould appear from the reports of the officers deputed by the Ad- 

 miralty to superintend the experiments, is in every way successful, the pre- 

 pared wood being as clear and sound when it came out as when first deposited.

Thiiiiics Tiiiiiiel.—'l'be shaft of the Tliames Tunnel on the M'apping side of 

 the river, in which the circular staircase is to be formed for foot passengers, 

 has now almost entirely disappeared, and uol more than (i\'e feet of it ap- 

 pears above the ground.' A month ago it was on a level with the tops of the 

 adjoining houses, and its gr.idunl sinking as the earth below is excavated has 

 excited the surprise of the inh;djitauts. In depth it is 60 feet, and it will be 

 raised 1.5 feet higher, and again sunk. Since the engineer of the Tunnel, Sir 

 Isambard Brunei, and three other gentlemen, passed under the driftway con- 

 necting the shaft «itb the Tunnel, many others have passed from one shore 

 lo the other by the same means. The completion of this stupendous work is 

 •close at hand. 



Axphalle.— For some time past the Seyssel Asphalte Company's men have 

 been actively engaged on the New Junction line of the Greenwich Railway. 

 in covering the arches, which when completed will extend over a space of 

 400,000 feet. 



New Steamers.— On the 21st instant a fine steam vessel was launched from 

 the building yard of \V. Pitcher, at Northfleet. She is for the Sicilian Go- 

 vernment, and named the " Maria Teresa." her tonnage is about 300, and the 

 collective power of her engine will be 120 horses, manufactured by Messrs. 

 Boulton, W'-M U Co. of Soho. A second vessel for the same government is 

 in considerable progress, of smaller dimension to carry two 50-)iorse engines, 

 from the s,ame establishment. 



A MiiiinlKre Steamer called the " Fire Fly," has been astonishing tbe fre- 

 ijucnters of the Thames by its rapid evolutions on the river, she is a moderate 

 sized boat propelled by Kricsson's propeller fitted in the stern and drivei>by 

 two oscillating engines, set horizontally, and at right angles the crank shaft. 

 The diameter of the cylinder is only 3 inches, and C-inch stroke, making 180 

 to 200 strokes [ler minute, worked with high pressure steam of 50 to 601b. ou 

 the square inch, generated by a very compact locomotive boiler. Tire engines 

 and boiler were entirely constructed by Mr. W'arrincr, formerly a pupil of 

 Messrs. Braithwaite, Milner and Co.. the'engines possess several improvements 

 worth introducing in larger engines, particularly the method adopted of con- 

 veying the steam into the cylinders instead of through the gudgeons, upon 

 which the cylinders oscillate. .She steams about 8 to 9 miles per hour through 

 the water, and has run «ith the tide from Blackwall to 'Westminster Bridge 

 in 50 minutes. 



Captain Ericsson is now in New York, and engaged by tlie American 

 Government to construct two engines of 1,000 horse power collectively for a 

 large sea-going vessel to be propelled by the Captain's propellers. 



Gatenno-plaatic Casts, — A letter from Munich informs us that the celebrated 

 Bavarian sculptor Stigelmayer has Ijrought to such a pitch of perfection his 

 galvano-plastic process, that its effects would be deemed fabulous were they 

 not publicly exhibited in the Jluseum of the Society of Arts. In the space of 

 two or three hours colossal statues in plaster are covered with a coat of 

 copper, which takes with the greatest accuracy the most minute and delicate 

 touches, giving the whole all the appearance and solidity of the finest casts 

 in bronze. M. Stigelmayer has also applied his process to the smallest objects. 

 as flowers, plants, and even insects, bringing them out with such accuracy, 

 that they seem to have been executed by the bands of the most skilful artists. 

 Highest Chimneif in the World. — The highest chimney in the world is at the 

 soda ash manufactory of James Muspralt, Ksq.. near Liverpool. It is tlie 

 enormous height of 406 feet above the ground, 45 feet diameter inside at the 

 base, 9 feet ditto at the top, and contains nearly 4,000,000 of bricks.— Zlai7i/
