hour. But as Mr. Gurney slackened its motion once or twice in the
course of trial, to speak to some one, and did not go at an equal rate
all the way round for fear of accident in the crowd, it is clear that
sometimes we must have proceeded at the rate of upwards of twenty
miles an hour."

The Engraving will furnish the reader with a correct idea of such of
Mr. Gurney's improvements as are most interesting to the public. The
present arrangement is certainly very preferable to placing the boiler
and engine in immediate contact with the carriage, which is to convey
goods and passengers. Men of science are still much divided on the
practical economy of using steam instead of horses as a travelling
agent; but we hope, like all great contemporaries they may whet and
cultivate each other till the desired object is attained. One of them,
a writer in the _Atlas_, observes, that "if ultimately found capable
of being brought into public use, it would probably be most convenient
and desirable that several locomotive engines should be employed on
one line of road, in order that they might be exchanged at certain
stages for the purposes of examination, tightening of screws, and
other adjustments, which the jolting on passing over the road might
render necessary, and for the supply of fuel and water."

An effectively-coloured lithographic of Mr. Gurney's carriage (by
Shoesmith) has recently appeared at the printsellers', which we take
this opportunity of recommending to the notice of collectors and
scrappers.
