REVIEWS — CANADA. AT THE UNIVEESAL EXHIBITION. 35 



Agricultural Machine makers, Crosskill & Co., and is now designated 

 as " Romain's Canadian Steam Cultivator." 



Mr. Tache published in Paris his prize essay entitled " Esquisse sur 

 la Canada considered sous le point de vue economiste," ■ — and in the 

 report before us a translation of this little work is given. He also 

 published a descriptive catalogue of the productions of Canada, ex- 

 hibited in Paris in 1855, and at the end of each enumeration of articles 

 embraced in the different classes, he gives their prices in this country, 

 and appends remarks as to their distribution, commercial im- 

 portance, &c. With reference to our progress in mining industry, we 

 find that the exportations of metals from our mines was valued at 

 £8,350 in 1852, and £74,000 in 1854. Attention is directed to the 

 value of the Tamarack, as a serviceable wood, rapidly growing into 

 favour in Europe. The oil of the black porpoise, Delphi nus minor, 

 is particularly noticed, on account of its remarkable property of re- 

 taining its fluidity at a very low temperature. Porpoise leather is 

 altogether an article of Canadian manufacture, and possesses many 

 valuable peculiarities. Birds' -eye maple was found to be excluded 

 from general use in the Paris cabinet manufactories, on account 

 of its price, and Mr. Tache very appropriately mentions the fact 

 that it is used for fuel in Canada, and ought to be supplied at a price 

 little above that of the commonest woods. 



We are next furnished with "Observations on the Exhibition," 

 which have already been published in the form of correspondence, 

 addressed, during the exhibition, to a portion of the French Press 

 of Lower Canada ; these are republished in the Report, by order of 

 the House of Assembly. Among many facts of interest to Canadians, 

 contained in these instructive and attractive letters, we are told that 

 the total area of the Crystal Palace at London, in 1851, was about 

 800,000 square feet — that of the Palace of Industry and its Annexe 

 at Paris, exclusive of the Palace used for the exhibition of Fine Arts, 

 1,200,000 feet. The number of exhibitors at London was 14,84:0, at 

 Paris 20,839. 



Bearing in mind the depopulated condition of many of our Canadian 

 rivers, which once swarmed with fish, Mr. Tache notices the illustra- 

 tions of the new art of Pisciculture, and the specimens of young fry and 

 spawn exhibited by Mr. Mallet, "who rears pike, carp, eels, &c, as 

 other people do puppies." Various plans of fish-ways up mill dams are 

 eminently suggestive, and ought to be introduced on every Canadian 

 river where a dam is constructed, tending to oppose the upward pro- 

 gress of the fish in spawning time, and thus to, depopulate our rivers.
