e, whose difference is observable at a glance: some have six wheels,
two of which are very large, about six feet in diameter, and the other
four much smaller. The two first only are driven by the machinery, the
others being merely what are called "bearing wheels." With this
description of engine more speed than power is obtained, and hence it is
used for passenger trains, where a high velocity is required, and where
there is usually little weight, comparatively speaking, to draw. The
others have only four wheels, not so large as the two just described,
but all driven by the machinery. Such engines I are more remarkable for
power than speed, and accordingly they are used for luggage trains. In
another shed, "The Hospital," will be found a number of engines laboring
under various disorders, sent here to be repaired.

But carriages and wagons are also built here. You enter a shed (of two
stories this time), and find wood shavings instead of iron filings, and
the hissing of a circular saw instead of the quiet, steady scraping of a
"cutter." Here all the woodwork of the carriages is executed, and when
ready they are hoisted through a large trap-door in the roof to the
second story, where they are painted and varnished, and, if first-class,
"up-holstered." In a store-room above stairs, are piled heaps of
cushions ready for the most expensive carriages; at a table is a boy
stuffing with horse-hair the leathern belts that hang by the sides of
the windows; and elsewhere an artist is painting the arms of the company
on the panels of a door. Here and there are boards placed before a
carriage, with the intimation "Wet!" indicating that you must not go too
near; and some of the carriages give evidence of having seen service,
but are now renewing their youth under the skillful hands of the painter
and the upholsterer. When ready to "go on the line," they are let down
through the trap-door, fixed on their wheels and axles, and sent to
relieve others that require repair.

Six o'clock strikes, and work ceases. In walking back leisurely to the
station, I saw many of the workmen digging in their little gardens,
"bringing themselves," as Emerson phrases it, "into primitive relations
with the soil and nature;" others were reading the papers of the day at
the Mechanics' Institution; others strolling among the green fields
round the town; and others walking to a class-room, to hear a teetotal
lecture; while some were proceeding to recreations
