THE CIVIL ENGINEER AND ARCHITECT'S JOURNAL. 



[Junk, 



inissioncrs of the Admiralty to communicate with Lieutenant-General Sir 

 George Murray, G.C.B. and G.C.H., for the purpose of making ex- 

 periments with it in tlie niarsljes at Wooiwicli, by bringing the full 

 force of canon balls against it. Accordingly, a number of planks of oak 8 

 inches thick and fir 16 inches square were joined together with the cement, 

 to tegether S feet in height and 8 feet in length of the side of a first-rate 

 ship of war, without anything else in the shape of bolt or security to assist 

 the composition ; and it was. set up as a target at the butt in the marshes, 

 when a number of officers of tlie Royal Artillery were present to witness the 

 experiment. Three shots were first fired, every one entering the target, the 

 third in a direct line with the bull's-eye within three inches of its outer circle. 

 The eflTects of these shots were wonderful, they tore the wood to pieces, and in 

 pnly one instance, where tlie joint bad not been good, they had no effect 

 upon the cement. — A hole six inches and a quarter in diameter was then 

 bored in the centre of the target, and an 32-pounder shell inserted and ex- 

 ploded by a match, which tore the wood to small splinters without in many 

 places in the least separating the composition. This new invention is said 

 to possess the power of expanding like India rubber in warm climates, and 

 will not become brittle under the coldest temperature. It appears to be a 

 great favourite with naval oflScers, as it is so clean, having only the appear- 

 ance of French polish. The name of the inventor is Mr. Jeffrey. 



The substances of which the cement is composed are simple, being merely 

 shell-lac and india-rul/l/er dissolved in naphtha in certain proportions ; and 

 heing insoluble in water, the purposes to which it may be applied are nume- 

 rous. Its value is about half the expense of common glue, the saving to the 

 country by its universal adoption will be incalculable, as the inventor has 

 been employed in experiments with it for upwards of two years, and has 

 found that in the absence of great friction it is in a manner imperishable. 

 An experiment was tried iu the dockyard, which shows the value a supply of 

 the cement will he to vessels which may be damaged at sea. Eight pieces 

 of wood were joined together in the form of a mast, and a strain applied to 

 them and to another mast of one piece of wood. The latter gave way first, 

 and the other only broke after being considerably bent and the application of 

 a rather great strain. By this substance, therefore, it is certain that ship 

 carpenters can have no difficulty in effecting repairs at sea, which could not 

 be done under any other circumstances. 



Scott's Monument. — An engraving has just been published, from a drawing 

 by the architect, Mr. Kemp, of the monument to the memory of Sir Walter 

 Scott, at Kdinburgh. It is a Gothic elevation, something in the style of 

 \\'hat are called "crosses," and bears in some portions a resemblance to the 

 great lower of the Cathedral at Antwerp. It is in style between the florid 

 and the simple Gothic, having Hying buttresses, finials, crockets, &c., and 

 being ornamented with quatre feuiles, and more minute embellishments. 

 There are many tabernacles, but they are not occupied by figures. The 

 statue of .Sir Walter is placed in the centre, benea'.h the principal arch ; it is 

 robed in a flowing drapery, and stands on a pedestal. The pedestal does not 

 partake of the character of the buiMing. and gives rather an incongruous 

 effect to ihe whole. There is an appearance of lightness and elegance about 

 the design, but it may be c|uestiontd whether the building has not too 

 much of the monastic or clerical style to suit exactly the character of 

 him it is intended to commemorate. 



Patent Wire Rope.— These ropes are likely, on account of their economy, to 

 become of extensive use for forming foot briJges over canals, and deep cuttings 

 of railways. Two wire ropes made at Mr. Andrew Smith's works at Poplar, 

 100 ft. long, 2J in. in circumference, and weighing 2i cwt.. cost 5/. os. formed 

 the main chain lor a suspension fcot bridge on the South-western Railway, 

 near the Weybridge station.
