 RUSSIAN CHAlN-BRID(iK. 



A chaiii-brldge, the first of its kind in Russia, is about to 

 be constructed over the canal of Moika. It will be executed, 

 after the design of Colonel Dufour, of Geneva, who has sent 

 to St. Petersburgh a correct model of one which he erected 

 in his own country last year. 



RAIL-ROADS — LOCOMOTIVE STEAM-ENGINES. 



On the 1 7th instant a grand experiment as to the power 

 of locomotive engines was performed at Killingworth Col- 

 lier}', near Newcastle-upon-Tyne, in presence of several gen- 

 tlemen from the committees of the intended Manchester and 

 Liverpool and Birmingham and Liverpool rail-road compa- 

 nies — when thjs result was as follows : The engine being one of 

 eight-horse power, and weighing, with the tender (containing 

 water and coals), five tons and ten hundred weight, was placed 

 on a portion of rail-road, the inclination of which, in one mile 

 and a quarter, was stated by the proprietor Mr. Wood to 

 be one inch in a chain, or one part in 792 : twelve waggons 

 were placed on the rail-road, each containing two tons and 

 between 13 and li hundred weight of coals — making a total 

 useful weight of 32 tons and 8 cwt. The twelve waggons were 

 drawn one mile and a quarter each way, making two miles and 

 a half in the whole, in forty minutes, or at the rate of 3| miles 

 an hour, consuming four pecks and a half of coals. Eight wag- 

 gons were then drawn the same distance in thirty-six mjnutes, 

 consuming four pecks of coals ; and six waggons were drawn 

 over the same ground in thirty-two minutes, consuming five 

 pecks of coals. Our correspondent also mentions, that the en- 

 gine must be supplied with hot or boiling, and not with cold 

 water ; and that two hundred gallons of water will take the en- 

 gine 14 miles, at the end of which the supply must be renewed.
