In two great head waters one of which bears the name of Tweed while
the other is throughout called Lyne it rises respectively in the Southwest and
Northwest extremities of Peeblesshire, by the head streams of the Ettrick the
Yarrow and the Teviot, it drains Selkirkshire from the furthest west; by the
Gala the Leader the Whiteadder and other streams it drains off the waters from
the southern acclivities of the Moorfoot and Lammermoor hills even from a line
but 11 or 12 miles south of Edinburgh; and from the remotest source to its influx
into the sea at Berwick upon Tweed it performs irrespectively of its winding a
run of about 100 miles about one third of which is in Peeblesshire and about another third
through or in contact with Roxburghshire.

The Tweed and Clyde for many miles from their sources flow so nearly in one direction as
never to diverge to any great distance from each other, and so long as they continue nearly parallel
they flow on almost the same level and keep a high table-land of country as if hesitating
whether to unite their waters or remain separate, or whether to turn their final course toward the
eastern or western ocean. In the vicinity of Biggar where the Clyde is 7 miles from the Tweed
and 30 from its own source and flows through a country by no means mountainous the indigenous
waters descend from within half a mile of it to the Tweed and 10 or 11 miles lower down running
in an opposite direction to that long pursued by the two great streams splits its waters
