[24] The Holland States undertook, in 1885, the improvement of the
navigable highway between the Rhine and the Schie. Whereas, up
to 1648, the rivalry of the cities tolerated navigation above
the dam only, and later allowed at this point a lock only
3.80 m. wide and 2.20 m. depth of water, they caused this lock
to be built at the same place with a breadth of 7 metres which
is spanned by movable bridges.
[25] By act of May 22, 1628, it is ordered that there be paid to
Adam Clippens, Engineer, who built the mud mill, a sum of 100
florins for the bid which he presented.
