The following text is taken from Appendix A - Details of Illustrations:
This figure is based on another illustration from 'Docks and Harbours' by L. F. Vernon-Harcourt. The original illustration was to a scale of 1:400 and labelled as Plate 15, figure 7. It included some detail of the sluicing arrangements and these have been excluded from this figure, in order to show clearly the arrangements for opening and closing the gates. It is not known precisely what form the machinery for operating the gates took or where precisely it was sited. The plan does not indicate whether the machinery was sited below the quay level or on top of it.
