taking as evidence the preponderance of passengers in the express
trains and the increase in traffic, without corresponding loss on
other lines, it would seem as if the receipts were increased by the
express service in a higher ratio than the increase in construction-
cost.
(5) An intra-urban railway, to be successful, cannot be a com-
promise in operation with stations situated at such intervals as to
be too far for short-distance travellers and not far enough to afford
the attraction of a high-speed service for long-distance passengers.
It should give one or the other service, or preferably a combination
of the two.

form of construction under a temporary roof in a street.
The Paper is accompanied by a tracing and several sunprints,
from which the Figures in Plates 5 and 6 have been selected
for reproduction.
