Figs. 13 and 14 - The entrance having been made good, the next point was to change the lock gates, which had been long in use. With sound outer gates it was possible to use the basin as a lock, and Mr. Riches accordingly first shifted the inner lock gates.

The manner in which this was effected is illustrated by Figs. 13 and 14, which show the method of slinging the gate and attaching the pontoon presently referred to.
