36 ANNUAL OF SCIENTIFIC DISCOVERY. 



feet in length by 9J feet in width, and divided into three classes, the 

 first class carrying 33 passengers, the second class 54, and the third 

 class 80 passengers each. They are all provided with 8 truck-wheels 

 each, with elliptic steel springs. The freight cars are all of them 30 

 by 9i feet, made in a uniform manner, having 8 wheel-trucks under 

 each. The imperial saloon carriages are 80 feet in length and 9 

 feet in width, having double trucks with 16 wheels under each. They 

 are finished into Jive different compartments, the imperial mansion in 

 the centre, 25 feet in length, fitted up with every luxury for sitting or 

 reclining, and with every comfort that the most ingenious mind can 

 devise, or the most refined taste can desire. Spacious platforms are 

 provided in front and rear. The whole cost of them exceeds $15,000 

 each. The depots at each terminus, and the station-houses and engine- 

 houses along the line, are on a plan uniform throughout, and on a 

 scale equally imposing. Fuel and water stations are placed at suitable 

 points. Engine-houses are provided at the distance of 50 miles apart, 

 built of the most substantial masonry, of circular form, 180 feet in di- 

 ameter, surmounted with a dome, containing stalls for 22 engines 

 each. Engines are to run from one engine-house to another only un- 

 der one heat, and are run back and forth from station to station, so 

 that they are kept constantly in charge of the same persons. Repair- 

 shops are attached to every engine-house, furnished with every tool or 

 implement that the wants of the road can require. Engine-drivers 

 have to go through the appropriate training before they are allowed to 

 take charge of an engine, and every arrangement provided that skill, 

 experience, or ingenuity can demand. American Railroad Journal. 



We may perhaps be allowed to add, that the contract price for the 

 engines was a little over $9,000 each ; and if the contractors were 

 not obliged to pay a duty on the steel imported, they could send en- 

 gines to England at a profit. The cars are of the same kind as our 

 American cars, thus differing from any others in Europe. When the 

 question between the short English and the long American cars was 

 brought up in the Council on Railroads, Col. Whistler stated his opin- 

 ion, which was violently opposed by every one, but the Emperor cut 

 short the discussion by telling Col. W. to do as he chose. Editors. 



NEW LOCOMOTIVE. 



ONE of a new kind of locomotive, for burning anthracite coal, has 

 recently been placed upon the Boston and Worcester Railroad. It is 

 invented and manufactured by Mr. Ross Winans of Baltimore. 



The engine, which is named the " Carroll of Carrollton," is of 28 

 tons' weight, with 2 driving-wheels, 7 feet in diameter, and 8 support- 

 ing or truck wheels, the driving-wheels being in the centre. It is 

 constructed for burning anthracite coal, and has a fire-box 6 feet in 

 length, 3i in width, and about 2 feet in depth, which will contain at 

 least a ton of coal. The. fire-grate is composed of stout, separate 

 bars, so arranged as to permit the firemen to turn them and shake out 

 the ashes, even when the doors of the fire-box are closed. 



Another and material improvement has been attempted in the con-
