THE CIVIL ENGINEER AND ARCHlTECrs JOURNAL. 



[December, 



Government Steamers. — A very lar^e armament has been ordered for the 



Valerius stfum frU-ate, now beiiiR built at Pembroke. On the upper deck she will carry 

 one fiH.pouiiHer of it5cwt. ; one lOinch gun of H5 cwt. ; and fnur 32-pounders of 66 cwt. 

 each, all ot which are to be mounted on pivotB. In addition she will be prepared to carry 

 eight 32-potnnler8 of 5t» cwt. each. 



The Vulcan. — A large spare screw-propeller, furnished by Messrs. Rennie, 

 haa been landed at Woolwich Dockyard, to be put on board this vessel. It is 14 feet in 

 diameter, and .''i^ tons in weight, and being made of the best brass, or mixture nearly ap- 

 proaching to gun-metal, is calculated to be worth I,2U0/. 



Screw Propellers.— It ha^ bitherto been usual to fit screw-propellers in tbe 

 rough shape in which they are cast, simply filing and smoothing the narrow edge of the 

 blade; but one of the michines in the factory at Woolwich dockyard has been btted in 

 such a manner as to plane the whole of one side of the blades, and on its being tried in 

 the factory for the first tlmo on a screw-propeller I* feet in diameter, cast of bra-s, for the 

 Archer, it ap[)ear3 to perform the work in great perfection. The difficulty of obtaining a 

 motion which would suit itself to the curve of the bhide of a screw-propeller muat be 

 •vident to every one who has witnessed its form, and yet it has been perfectly accom - 

 plished in this instance. 



The Termagant, 24, screw-frigate, by White, of Cowes, built in Deptford 

 dockyard, !,.').'>(; tons, G2U-horse power, by Seawiird, was ii^u\n tried at Portsmouth. Nov. 

 ll/, at the mt-asiued mile in Stokes Bay, with light airs and a smooth sea, to endeavour to 

 obtain a more creditable result than on the former occasion. Captain Horatio Austen, 

 C.B.. of the Blenheim, commanded the ship on this occasion. Mr. White, her desik-ner, 

 was on board; as also Rear-Admirals Frescott, C.B., and Sir Charles Napier, K.C.B., 

 Hith Mr. Murray, the chief engineer of the docltyard, and a host of naval officers from 

 the college, and elsewhere ashore, the trial having attracted much attention in the ser- 

 vice. She went out of the harbour about 11 o'clock, trimmed to a draughtof 17 ft. 10 in. 

 aft and U» ft. 1 in. forward, her midship portsill being then 6 ft. U in. from the water. 

 Her former draught was 16 ft. U In. forward, and 17 ft. 3 in. abaft. She was considered 

 at her load draught for sea service, being all complete for offic«is and men, topgallant 

 masis struck, and yards an end and pointed, all her guns and shot on board. The follow- 

 ing is tbe result of each run at tlie measured mile : — 

 Knots. 



First run 8-39U 



Second run 8 551 ] 



FmmhUun ;.';;;!!!'.;;;;:!: tlHi j-GMng a mean speed of 8-644 knots per hour. 



Fifth run .,'.",'.'.'.".'*,*/.'.'.".'.".'. 9137 ) 



Sixth run 7627-^ 



Revolutions (mean), 32; mean revolutions of propeller, 64 ; pressure of steam, 12 lb. ; 

 thermometer in engine-room, 86^; stokehole, 108'-'; temperature on the upper deck, f'2° ; 

 meau barometer, 27^ inches. She turnei a whole circle to port, with the engines in full 

 play, in *> min. 9 sec. in a space the mean of which was about four limes the ship's length. 

 This result is certainly more respectable than that obtained on her triul a few days since, 

 with rough wind and weather; but is, after all. but a beggarly account of service to be 

 expected in return for an expenditure of 70,000^, especially when placed in cuntparison 

 Willi the performances of the Arrogant screw-frigate, which achieves, under all circum- 

 stances, more speed, although 306 tons more burden, with 'J(»0-hoise power less. 



The Conffict. — On Tuesday, the 13th ult., Her Majesty's steam-sloop 

 Conflict, H, of 4IJ0 horse power. Commander T. fi. Drake, hiade ;ui exi)eiimental trip to 

 the Kddystoiie,to test the power of her screw. From Plyniuuth she started from abreast 

 of the Breakwater Lighthouse, and reached the Kddysiune Lighthouse, a distance of 

 rather more than 10 miles, in 1 hour and .'>"i minutes, to cover the ground, being an 

 amount of lime for such a distance which *per se' is not satisfactory. 



Steayn Screw-Propeller, Minx. — This vessel weut down the river from 

 Woolwich dockyard on the 14th ult., te test the disc-enudne of 10 horse power wiih which 

 she has been fitted. The engine, at starting, made 130 revolutions per minute, but the 

 average during the trial in Long Reach wiis I'JO revolutions per minute. The speed at- 

 tained was r)271 knots with the tide, and 2'0 knots awainst the tile, giving an averiige of 

 3'iJ25 knots per hour. The engine woiked diultig tbe tiial with a pressure of tin lb. to 

 the square inch. The speed was comparatively so little, thiit she was towed back to 

 Woolwich by the Monkey steam-vessel, at the rate of 6'-15 knots per hour. 



Launch of the Propont'is. — A fine screw steamslii|), built of iron by Messrs. 



Blare and Co., Blackwail, from a design by Mr. T. Waterman, jun., hiis been launched. 

 The Propontis will be the third constructed fur the General Screw Sldpping Company, 

 JMid of the same class as their two vessels the Bosphorus and Hellespont. Her dimen- 

 tiona are — length, 17& feet ; breadth, 2'^ ft. fi in. ; deptli, 17 ft. (» in. ; and tonnage, .'J3l 

 8ti'lt4. She is to be fitted with auxiliary engines of 8U-horse power, by Messrs. Maudstay, 

 Sons, and Field, and will be commanded by Captain Brenan. 



French Steamers. — Monsieur Ca\e, the great French engineer, has, accord- 

 ing to the * Moniteur Industriel,' supplied a fourth steam tow-boat for the Rhine, which 

 is held forth as a great feat, and a triumph over the Eni^lish, likewise that he is the 

 great champion of the oscillating engine.
