*'Tlie foregoing are the averages of speed on a fair level road,all circumstance*, 

 such aa stoppages for water, being taken into consideration. The speed, 

 however, may be increased even beyond six miles an hour, though that is a 

 sufficiently high rate for a heavy goods engine to travel. 



*' The weight of a large engine is about 14 tons, and of the second size, about 

 10 tons. The width, from outside to outside of driving wheels, is about 7 feet, 

 though of course this is increased, if the wheels are inade very wide to admit 

 of the engine travelling over soft ground. 



*' The engines are respectively about 21 and 18 feet long over all by about 

 10 and 9 feet high to the top of framing. The driving wheels are 7ft. 6im 

 by 6ft. 6in. in diameter, by 12 to 15in. wide ; the steering wheels are 3ft. 

 6in. and 3ft. in diameter, by 10 to 12in. wide. _, 



"The consumption of coke or steam coal is in the large engine about 

 841bs. per mile, in the smaller machine about 561b,, per mile taking the 

 average of roads. In Woolwich dockyard the engine does not burn more than 

 about 2k art of coke per day. The fire box can be constructed to admit of 

 wood being used as fuel if necessary. The tanks contain about two hours* 

 supply of water, and a day's supply of fuel can be carried on the engine. 



" A large engine will draw about SO tons on ordinary roads, with gradients, 

 say one in twelve, while a small one will draw about 15 tons. On hard, smooth, 

 level roads, a much greater weight than above quoted can be drawn with ease 

 (see experiments detailed in pamphlet, p. 17). 



*' The Company also supply waggons capable of carrying from 8 to 10 tons 

 of goods, mounted on springs, fitted with proper couplings, break-power, 

 arrangements for backing, &c., complete to accompany engines, which they 

 track accurately, either singly or in train, even in turning comers at right 

 angles, price £100 each. 



" The price of passenger cars capable of holding say 20 passengers, fitted com- 

 plete, £200. 



*' For dockyards or arsenals, or any fixed work, two attendants (one a 

 skilled mechanic) would be sufficient for the engine, but when long distances 

 have to be traversed, another laborer or two would be necessary to attend 

 to waggons, &c. 



*' The following is an estimate of the daily expenses of a large engine and 

 waggons, supposing they work 250 days in the year, and that twelve waggons 

 were employed so as to allow four being always loading, four unloading, and 

 four in transit : —

" An engine will draw f©ur waggons loaded with 8 tons each, say 32 tons on 

 any ordinary road, at a speed of about three miles an hour. It would, 

 therefore, take such a load a distance, say, for example, fifteen miles, and 

 return with the empty waggons the same distance, 30 miles in all, in one day 

 of ten hours. 



" The cost of this would be, as shown, £5, or at the rate of 2^d. per ton 

 per mile, whereas if a load could be found for the engine to bring back equal 

 to the one it took, the cost would be reduced to exactly one half, or otherwise 

 in proportion to the load. The price would probably be increased abroad by 

 the higher rate that would have to be paid for labor and fuel. 



*' The snow would not make any difference as to the working of the engine, 

 the wheels being fitted with "spades" or "teeth" capable of being protruded 

 ■or withdrawn at pleasure (see pamphlet, p. 3). 



** It will not be requisite to have an additional steering wliedl to the engine.
