THE CIVIL ENGINEER AND ARCHITECT'S JOURNAL. 



[August 



The spceil is equal 10 about 12 miles through the water ; and the consumption 

 of fuel is about the same as on railways. In consequence of the engine being 

 fixed in the boat instead of moving at such high velocities it does on tlie 

 rails, there is nothing like the same wear or so much lialjility to derange- 

 ment. Tliere are one or two evils attendant upon the ])resent use of the 

 locomotive engine ; one is, that in conseijuence of the muddy state of the 

 water of the river Tiiames, the boiler is apt to prime, which may be obviated 

 by making a larger steam chest than ordinary ; there is also an unpleasant 

 horizontal vibratory motion in the boat, in consequence of the horizontal 

 and rapid movement of the pistons, which we think can be got rid of by 

 placing the cylinders diagonally on the sides of the boiler. Tins alteration 

 would also allow the moving parts to be got at much better than they now 

 are, which, in consequence of being placed under the boiler, are very awk- 

 ward to be got at. No doubt these defects will be easily got rid of. and 

 other improvements introduced, under the able hands of Messrs. Braithivaite, 

 Milner, and Co. 



]HISCEI.I.ANEA. 



In last month's Journal we gave an account of the removal and shipment 

 of the immense block of Granton stone presented by his (Jrace the Duke of 

 Buccleuch for the statue of the immortal Nelson, and wdiich is intended to 

 grace the summit of the column now erecting in Trafalgar-square by Messrs. 

 Grissell and Peto ; we have now to record it.-; arrival into the river Thames, 

 and removal to Trafalgar-square. On Saturday, June 25, it was safely landed 

 at Mr. Foote's wharf, AUngdon-street, Westminster, in the presence of a 

 large number of spectators, and was conveyed by the aid of 22 horses through 

 Parliament-street and Whitehall toils last and final resting-place, Trafalgar - 

 square. The crane by which this ponderous mass was landed was erected 

 about three years since, by Mr. Luke Embleton, of Southwark, under the 

 superintendence of Mr. Thomas Searle, of Wapping Wall, and is a beautiful 

 piece of mechanism. The work, however, of its elevation to the top of the 

 column still remains to be eficcted, and we hope its accomplishment will be 

 as successful as its journey hitherto. The stone in question is slated to weigh 

 30 tons, and has already been reduced to favour its more easy removal from 

 a block weighing at least 4j tons ; it is of the description known as " Craig- 

 leith," of the liver rock, and in point of iluraliility equal to granite. We 

 understand ihat the removal of this stone from the neighbourhood of 

 Edinburgh to Charing-cross has been efTeeted without either the breaking 

 of a chain, or the splintering of a handspike. Mr. Bailie, the sculptor, has 

 now his part to perform, 



Claudct^s Daguerreotypes. — We were much delighted to witness at the Ade- 

 laide flallery M. Claudet's instantaneous process of taking portraits. To 

 him is due an improvement which, we may say. is almost equal to the original 

 discovery. Previously to this improvement, ihere was considerable difficulty 

 in obtaining a faidiful likeness, in consequence of the time required tor a 

 sitting, and also the necessity for having a clear sunny day for the operation ; 

 but now, in a strong light, it will require hut a moment or two, and even on 

 a cloudy day. as it was when we last witnessed it, portraits can be taken in 

 from 10 to 14 seconds. To show the instantaneousness of the process, M. 

 Claudet is enabled to take portraits of animals, trees, plants, &c. He has 

 also introduced another important improvement — that of introducing a back 

 ground, representing a landscape or interior. During the last month M. 

 Claudet was honoured with a visit from the Queen Dowager, who had her 

 portrait taken as well as of those of the suite who attended her. With these 

 she was highly delighted, and expressed her astonishment at the rapidity of 

 the process. We wish we could see this valuable processs more extensively 

 employed in obtaining copies of some of our finest specimens of sculpture, 

 paintings, and public buildings. Although M. Claudet at first devoted his 

 attention wiih much praiseworthy eflect in obtaining portraits, if we may 

 use the term, of all the principal buildings in London, Paris, and Italy, he 

 met with little or no encouragement. He was, therefore, obliged to devote 

 his attention to a more profitable department — that uf human portraiture, 

 and. if we judge rii^htly from the number of persons who daily flock to his 

 studio at the Ailelaide tjallery. he will find it amply enrich his coders, and 

 make up f(jr his prcvi(, us losses. We wilh much pleasure recommend a visit 

 to his eslablishment where may be seen porlraits of many public characters, 

 and of many celebrated buildings. 



Asphallc Roofing.— \t was remarked as a singular cirenmstance, during (he 

 conflagration at Hamburg, that roofs covered with asphalte, of which there 

 are some here, opposed rather than encouraged the progress of the (lames. 

 It was imagined, on account of the substance of which Ihese roofs were com- 

 posed. Ihat they wouki easily catch fire, and be the cause of great mischief; 

 such, however, was not the case, for it appears that the fire had little or no 

 cfiect on them : and when the roofs of the houses fell in, the asphalte, in 

 which a sort of nibblt is mixed up, was found to have resisted the ellects of 

 the heat, and like a mass of dirt, served rather to smother the flames than 

 to give them increased vitality. — Time.K.
