 highest part over the tunnel, is at an elevation of 60 feet above the water in the tunnel. Within a little distance of the tunnel, are two reservoirs, for the supply of the canal, which cover one hundred and four acres of land, and will contain twelve hundred thousand cubic yards of water. From Foulridge the canal proceeds to near Barrowford, where it locks down from the summit 70 feet towards Liverpool; crosses Colne Water by an aqueduct; passes near Carr Hall (a seat of Colonel Clayton's) and Dancer House to the town of Burnley, which it circumscribes on three sides, and at which place an embankment has been carried for one thousand two hundred and fifty-six yards in length, at above 60 feet high, and aqueducts made over the Rivers Brown and Calder, and a road aqueduct under the canal; thence the canal proceeds to near Gannah, where there is another tunnel five hundred and fifty-nine yards in length; thence by Hapton, Altham, Clayton Hall, Henfield, to Church Valley, whence Messrs. Peels' short branch runs to their print works at Church; now crossing the River Henburn by an aqueduct, the main line proceeds past Rushton and White Birch to the town of Blackburn, sweeping on the south side of this town to a place called Grimshaw Park, where by six locks there is a fall of 54 feet 3 inches; thence passing over Derwent Water by an aqueduct, it runs by Livesey Hall, and passing Roddlesworth Water by another aqueduct, proceeds to near Chorley; thence to Cophurst Valley, and here locking down 64 feet 6 inches by seven locks into the head level of the Lancaster Canal, at Johnson's Hillock. At this part of the line there is an interval of eleven miles of the Lancaster Canal upon one level, when the Leeds and Liverpool Canal again commences near Kirklees, at the head of a range of twenty-three locks, which brings the canal down 214 feet 6 inches from the level of the Lancaster Canal to the basin at Wigan. Here it may be observed, that the basin at Wigan is situate upon that part of the canal made under the powers of the River Douglas Navigation Act. From this basin to Newburgh constitutes the Upper Douglas Navigation, a distance of seven miles, in which there is a fall to Newburgh of 30 feet.

In this last-mentioned distance the principal part of the coal carried by the Leeds and Liverpool Canal to Liverpool, is put on board the vessels; as also the coal sent down to the Ribble.
