Note 26b — PART I. INTRODUCTION.

In 1645, five or six years before Denver Sluice was erected, Lynn Haven was in a very good condition. It had two channels, one called the East, the other the West Channel, in which the biggest ships, drawing 13 or 14 feet water, sailed up and down on the neap as on the spring tides. One John Attleson, aged 80, deposed that for 60 years and upwards, he had known the river Ouse, and all the rivers falling into the same; and that before the erection of the sluices near Salter’s Lode, all the rivers were free and open, and received such quantities of water by the flood from sea, that large barges with from 26 to 30 chalders did constantly pass with great ease up to Cambridge town.—See Budeslade: also Elstobb’s Observations, p. 23, 24.
