Page 364:-  "[Pilotage.] ..."
"The Barrow pilot-vessel is a ketch-rigged, steam vessel with the word "Pilot" painted in white letters on the sides. This vessel does not cruise regularly, but, when vessels are due, it will cruise between Lightning Knoll light-and-bell-buoy and Morecambe Bay light-vessel from 3 hours before until one hour after high water, unless prevented by stress of weather or other unavoidable cause. Vessels requiring a pilot should make the usual signals; the signal to be made by a vessel requiring a pilot in foggy weather is four long blasts; there is no special reply to this signal. They should await the pilot at about one mile south-westward of Lightning Knoll light-and-bell-buoy; those arriving off the port after high water should anchor and be under way again 2 hours before high water."

Page 379:-  "Tidal streams. - The tidal streams at the Lightning Knoll light-and-bell-buoy (Lat. 54~ 00' N., Long. 3~ 14' W.) are rotatory, and not strong. The greatest strength is at 2 hours after high water at Liverpool, when the stream runs from 1 1/2 to 2 1/2 knots between west-north-westward and westward, and again at half flood, when its rate varies between one and 1 1/2 knots, and its direction between east-south-eastward and eastward."
