any OF the machinery, this part OF the journey was per
ioi med in unsatisfactory manner. The defect alluded
to, was the looSeung OF OF the piston rods Tom the
key not having been accurately fitted The three last
miles into Penkildge were performed with only one
engine At Penkridge, new key was put INTO the
piston, and portion Of the boiler cut oat and ft De-

bad, most kindly sent u OF quality so superior that
on leaving Trentharn, the adjacent aud lofty hills were
assembled with such rapity, that wellmouned horcmen
could not keep pace without distressing their ANIMALS.
Mr. Cork, coach proprietor, timed the vehicle and found
that two miles, nearly all up hill, were cleared IN six
minutes and half The difference in speed arising from
the quality of the fuel now apparent; and the coach

will remove all doubt:
