aceful,
2 m. above Lanark, is divided into two parts by a mass of tree-clad
rocks in mid-stream, and has a height of 30 ft. From this spot the river
runs for half a mile through a rugged, red sandstone gorge till it
reaches Corra Linn, the grandest of the Falls, where in three leaps,
giving it the aspect of a splendid cascade, it makes a descent of 84
ft., which, however, it accomplishes during flood at a single bound.
Almost 3/4 m. below Corra Linn, Dundaff Linn is reached, a fall of only 10
ft. Farther down, 1-3/4 m. below Lanark, at Stonebyres Linn, reproducing
the characteristic features of Corra Linn, the river descends in
ordinary water in three leaps, and in flood in one bold drop of 80 ft.
Within this space of 3-3/4 m. the river effects a total fall of 230 ft., or
61-1/3 ft. in the mile. From Stonebyres Linn to the sea the fall is
practically 4 ft. in every mile. The chief villages and towns on or
close to the river between its source and Glasgow are Crawford,
Lamington, New Lanark, Lanark, Hamilton, Bothwell, Blantyre and
Uddingston. At Bowling (pop. 1018)--the point of transhipment for the
Forth and Clyde Canal--the river widens decidedly, the fairway being
indicated by a stone wall continued seawards as far as Dumbarton.
Dunglass Point, near Bowling, is the western terminus of the wall of
Antoninus, or Grim's Dyke; and in the grounds of Dunglass Castle, now a
picturesque fragment, stands an obelisk to Henry Bell (1767-1830), the
pioneer of steam navigation in Europe.

As far down as the falls the Clyde remains a pure fishing stream, but
from the point at which it begins to receive the varied tribute of
industry, its water grows more and more contaminated, and at Glasgow the
work of pollution is completed. Towards the end of the 18th century the
river was yet fordable at the Broomielaw in the heart of Glasgow, but
since that period, by unexampled enterprise and unstinted expenditure of
money, the stream has been converted into a waterway deep enough to
allow liners and battleships to anchor in the harbour (see GLASGOW).

Clydesdale, as the valley of the upper Clyde is called, begins in the
district watered by headstreams of the river, the course of which in
effect it follows as far as Bothwell, a distance of 50 m. It is renowned
for its breed of cart-horses (specifically known as Clydesdales), its
orchards, fruit fields and market gardens, its coal and iron mines.
