In short distances, to know precisely at what time it is necessary to
start, to arrive at any place at a certain hour, the driver has only
to ascertain the distance, and to regulate the pace by the following
table:--
4 miles an hour, 1 mile in 15 minutes.
5 ditto ditto 12 ditto
6 ditto ditto 10 ditto
7 ditto ditto 8½ ditto
8 ditto ditto 7½ ditto
9 ditto ditto 6½ ditto
10 ditto ditto 6 ditto
In the streets of London, ten minutes at least, in every hour, must be
allowed for stoppages.
