Of the streams possessing something of historic interest and scenic charm, the Looe must be mentioned because of the lovely vale through which it flows between Duloe and Morval and the association of the river with the ancient Parliamentary boroughs of East and West Looe at its mouth. The Seaton, the St. Austell river, the Hayle, the Gannel, and the Hel, each and all have their individuality, owing allegiance to no other river tyrannous of its tributaries; but the three principal streams of the county, the Tamar, the Fowey, and the Fal, which have been selected for special notice here, have a virtual monopoly of interest and attention. The /Tamar/ possesses, in a singular degree, the more striking characteristics of the Cornish rivers, and is fairly entitled to the distinction of first consideration at our hands. Having its rise at Woolley Barrows, in the extreme east of the westernmost county, a short distance from its source Tamar becomes the boundary between the counties of Devon and Cornwall, and so continues during nearly the whole of its course, some forty miles. Flowing distinctly southward, the river leads a quiet life for at least a league, till, gaining in size and importance, it gives its name to the pretty village and parish of North Tamerton. Thenceforth "Its tranquil stream Through rich and peopled meadows finds its way." At St. Stephen's-by-Launceston it receives the Werrington stream, and expands into a beautiful lake in Werrington Park. Below the lake the impetuous Attery stream joins the now brimming river, which, passing under Poulston and Greston, reaches Tavistock New Bridge, where we are on the "scientific frontier" of Devon and Cornwall. At this point, too, the Tamar enters upon a new stage of its existence, leaving its lowly moorland birth and quiet ordinary youth behind it, and beginning a career which is henceforth the cynosure of all eyes. Hurrying by Gunnislake, the busy little hamlet of workers in clay and stone, at Weir Head the river literally leaps into fame. From the coaching hamlet it has slided on through a woodland glade of bewitching beauty, which wins a spontaneous outburst of admiration from the visitor who, haply, has chosen to approach the favoured scene by the serpentining sylvan walk from Morwellham to Weir Head. Here its waters break in a pretty cascade over the artificial ridge of rocks that reaches from bank to bank. Then they prettily describe a circle about the islet in mid-stream, gaining new life and movement from the impetus. With the briskness of a waterslide the Tamar rushes on to Morwellham. A charming variety of river-glimpses may be gained through the luxuriant foliage at Weir Head, the views hereabouts having become the objective of the highly popular steamer-trips from Plymouth, Devonport, and Saltash, which have constituted "Up the Tamar" quite a colloquialism in the West.
