The
evidence, however, of Mr Macneill, shewing the greater
efficiency, with diminished expenditure of fuel, by locomotive
engines on railwavs, convinces the committee, that experience
will soon teach a better construction of the engines, and a less
costly mode of generating the requisite supply of steam.
Nor are the advantages of steam-power confined to the greater
velocitv attained, or to its greater cheapness than
horse-draught. In the latter, danger is increased, in as large a
proportion as expense, by greater speed. In steam-power, on the
contrary, 'there is no danger of being run away with, and that of
being overturned is greatly diminished. It is difficult to
control four such horses as can draw a heavy carriage ten miles
per hour, in case they are frightened, or choose to run away; and
for quick travelling they must be kept in that state of courage,
that they are always inclined for running away, particularly down
hills, and at sharp turns of the road. In steam, however, there
is little corresponding danger, being perfectly controllable, and
capable of exerting its power in reverse in going down hills.
