38 BEYIEWS — CANADA AT THE UNITEESAL EXHIBITION. 



Our castings did not meet with much favour, and the reasons may 

 be drawn from the following observations by Mr. Tache : 



" What lightness is found in the railings, the iron seats, &c., of the English 

 manufacture of the Coalbrookdale Company in Shropshire, and how cheap also 

 are the articles? The reason is plain, the purchaser has not to pay for a lot of 

 useless iron." 



"What elegance there is in the stoves and other articles of French manufac- 

 ture, from the blast furnaces of the Marquis de Vogue of France? These designs 

 of hunting and historical scenes are bas-reliefs of art, and the articles are not 

 dearer on that account, because the material is not wasted ; and as to the casting, 

 the beautiful costs no more than the most deformed piece that ever was moulded. 

 This is now generally understood; and in England where art is less perfect than 

 in France and Belgium, the proprietors of foundries endeavour to procure artists 

 from those two countries. A French sculptor, M. Geneste, is at this moment, in 

 the receipt of a salary of £2000 per annum from an English manufacturer." 



"The art of combining the useful with the agreeable is the climax of materia! 

 progress. The study of the beautiful in art, is, to the intellectual man, what the 

 study of truth is to his moral existence." 



From many admirable inventions and applications which commend 

 themselves to the attention of Canadians, and which are specially 

 noticed with that object by Mr. Tache, we select some which appear 

 likely to meet with adoption and favour. A smoke consuming coal 

 grate, which is in the shape of an endless chain, and uncoils as the coal 

 is consumed, thus combining advantages of health and economy. A 

 machine by M. Chevalier, which by means of an endless steel wire 

 adapted to pullies, saws with the greatest regularity the hardest stone, 

 as quartz, granite, and even crystal. Two machines by M. Sautreuil, 

 of Lechamp ; one for preparing flooring boards by a single stroke, 

 the other a planing machine, for smoothing timber for building pur- 

 poses, on four sides at once. Messrs. Irey and Holy, of Paris, have 

 introduced caoutchouc as a material for springs in all their machines. 

 In the manufacture of chemical matches, for the production of an 

 instantaneous light, Austria employs not less than 20,000 persons, 

 and the highest price for round matches is only one penny per thousand. 

 Mr. Quinti, of Vienna, showed how by interrupting the current by 

 non-conductors, two communications may be transmitted simultan- 

 eously in opposite directions by the same wire. The preservation of 

 food by the perfect exclusion of external air is easily accomplished 

 by the immersion of game, or other meats, in a warm solution of gel- 

 atine. The celebrated Russia Leather is tanned with the decoction of 

 willow bark, and impregnated with an oil extracted from the bark of 

 the bouleau. A curious result of the artificial preparation of a val- 

 uable pigment is shown in the manufacture of Ultramarine. The nat-
