Ijsselmonde, to Gouda, whence there is canal communication with the
river Amstel, to Amsterdam, and also by the old Rhine, _viâ_ Leiden
and Haarlem, to Spaandam, to the North Sea Canal. There is a great
traffic in the former of these two routes, there being always a great
collection of craft at the sluices at Gouda, waiting their turns to
pass. Large and improved locks are said to be urgently required at this
place. The depth of water on this route is at least six feet.
