 It afterwards takes a southerly course by Miller Hill Row, to within half a mile of the west side of the town of Dalkeith, where it crosses the North Esk River; thence, to the banks of South Esk River, at Dalhousie Mains, near Newbattle Abbey, from whence, the last act [i.e.a second Act of Parliament] enables the company to extend it to Newton Grange.There is a branch from Wanton Walls to Fisher Row Harbour, on the Firth of Forth; another from Cairney to the collieries situate on the east side of the Esk, at Cowpits, near Musselburgh ; and another by a subsequent act, which extends to Leith Harbour.
