It is marvellous to see how the lichen attaches itself to the granite. A harshly glaring piece that the quarrymen have cut is touched with fine specks that spread into black and crocus-yellow circles, and tone down the stone to a sober tint. Unhappily of late years there has been much firing of the furze and heather on the moor, and the flames destroy the beautiful lichens and mosses, and leave the old stones white and ghostly, not to be reclothed with the old tints for centuries.
I do not think that we have any idea of the slowness with which the lichens spread; a century to them is nothing—it passes as a watch in the night. There is a granite post I often go by. It was set up just seventy years ago, and on it the largest golden circle of the Physcia parietina has attained the diameter of an inch. Mr. Parfitt mentions in connection with it a rocky crag at Baggy Point, North Devon, where it covers the whole surface with a coat of golden colour. It spreads more rapidly on slate than it does on granite, and especially on such slates as are liable to rapid disintegration. The Woodland and the Coryton slates are readily attacked by it. The growth begins with a splash about the size of a sixpence, and increases to that of a plate, when the centre breaks up, and the ring becomes detached in fragments which meet others, and so appear to cover the rock or roof.
One of the most beautiful of the lichens on the moor is the coral moss, Sphærophoron coralloides. It is a pale greenish-white, upright-growing lichen, that forms a cup, and somewhat resembles an old Venetian wineglass. Then points of brilliant scarlet form round the lip of the cup, and increase in size till the whole presents a wonderful appearance as of sealing-wax splashed over the soil. It is not confined to the moorland, but grows also in woods, where there has been a clearance made. I came upon a wonderful carpet of sprinkled scarlet and white on one occasion, where there was a woodman's track through an old oak coppice. But it must be capricious, for of late years when searching for it in the same spot I have found no more. The black coral moss is scarce, but it has been found about Lynx and Yes Tors.
The birds on Dartmoor have a hard time of it, not only because of the guns levelled at them, but because of the "swaling" or burning of the moor, which takes place at the time when they are nesting. In East Anglia there are along the coast the "bird tides," as the people say. At that period when the plovers and sea-mews are nesting in the marshes, there are unusually low tides, a provision of God, so it is held, for the protection of the feathered creatures whilst laying and hatching out their eggs. So the ancients told of the halcyon days when the gods had pity on the seabirds, and smoothed seven to eleven days in the winter solstice, that they might with safety hatch their young. But on Dartmoor man has none of this pity; he selects the very time when the poor birds are sitting in their nests on their eggs, or are cherishing their callow young, for enveloping them in flames. The buzzard, the hen-harrier, and the sparrow-hawk are now chiefly seen in the most lonely portions of the moor. Gulls visit it on the approach of stormy weather; but the ring-ouzel is there throughout the year. The golden and grey plovers are abundant; the pipe of the curlew may be heard; black grouse and quail may be shot, as also snipe. By the water, that living jewel the kingfisher can be observed watching for his prey, and about every farm the blue tit, called locally the hicky maul or hicka noddy, is abundant. The sand martin breeds in a few places. The heron has a place where she builds at Archerton.
The snow bunting and cirl bunting are met with occasionally.
The cuckoo is heard on the moor before he visits the lowlands. "March, he sits on his perch; April, he tunes his bill; May, he sings all day; June, he alters his tune, and July, away he do fly." So say the people.
One of the freshest and most delicious of Devonshire folk-melodies is that connected with a song about the cuckoo.
"The cuckoo is a pretty bird,
She sings as she flies;
She bringeth good tidings,
She telleth no lies.
She sucketh sweet flowers
To keep her voice clear,
And when she sings 'Cuckoo'
The summer draweth near."[26]
There is a saying among the country folk:—
"Kill a robin or a wren,
Never prosper, boy or man."
