The winding river gains a new glory from its beautiful and impressive surroundings as it flows at the base of Morwell Rocks, those wonderful examples of Nature's carvings, set in the midst of luxuriant foliage that here hides their shaggy sides and there throws into bold relief an awe-inspiring pile. The Rocks are unique in their romantic beauty, even though they figure among the many objects of interest in a highly picturesque neighbourhood. The Chimney Rock and the Turret Rock are happier instances of descriptive nomenclature than usual. Bolder still is that most striking specimen of natural architecture, Morwell Rock, the massiveness of which doubtless gained for it the capital distinction. To the giddy height of the topmost rock, above the far-stretching woodland of Morwellham, scarce a sound of the rippling river comes; but the silver thread of its serpentine course may be traced afar through the romantic valley, winding about Okel Tor and the great bend that forms the peninsula between Morwellham and Calstock, and then taking its favoured way through cherry orchard-groves on to the haven under the hill. [Illustration: THE RIVERS OF CORNWALL.] The river is navigable to Weir Head, but Morwellham is the highest point reached by the steamers. Pursuing the line of least resistance, the Tamar now makes a tremendous sweep about the hill on which Calstock Church stands. But ere the first view of the "two-faced church" is caught, an interesting riparian residence is skirted--Harewood, the scene of Mason's play of _Elfrida_, now the office of the Duchy of Cornwall, but formerly one of the Trelawny properties. Calstock, if it please you, is the centre of the old "cherry picking" district, though to-day its strawberry gardens must rival the orchards in their remunerative return to the industrious population of the quaint little town that seems to have grown away from the water's edge to the pleasant Cornish country beyond Tamar bank. Still, if you would see Calstock in its daintiest garb and most delightful beauty, come you when the pretty cherry blossom decks the groves by the river, and the tender pink and white clothes the orchard lawns to the uplands.
