But it would be a pity not to turn aside into the ancient town of Leatherhead, displayed in full to wayfarers from Epsom to Guildford, its chief thoroughfare guiding them to the bridge at which stands the old “Running Horse.” This is taken to be the very tavern which Skelton, Henry VIII.’s learned tutor and doggerel poet, hoarsely sang of as keeping an open door—

To travellers, to tinkers,
To sweaters, to swinkers,
And all good ale drinkers.

But Skelton’s hostess is more than once said to dwell “on a hill” beside Leatherhead, and so to describe the riverside situation of this house seems a license not to be granted even by poetic sessions. A little way down the stream the cyclist might wash off his dust in a mill turned into a quaint swimming-bath. Leatherhead has fewer signs of antiquity than of prosperity, surrounded as it is by large houses, one of them St. John’s School for the sons of the clergy, a former headmaster of which had a son of his own known to novel readers as “Anthony Hope.” The two stations are close together on the east side of the town, where a path leads down the bank of the Mole. On the other side is the Church, a mainly fourteenth-century one, with some noticeable coloured glass, lying beneath the yew-dappled slopes of Leatherhead Downs, which we shall presently come to by the Roman Road across them.

The high-road to Dorking goes out under the Church, to hold up the Mole valley. But the traveller not bound, Ixion-like, to a wheel, should by all means leave it by a lane just beyond the town, crossing the Mole and striking into the path above mentioned as turning off the Guildford road beside the railway. This path takes him near the river for a couple of miles, by the lower edge of Norbury Park, between its heights and those of Leatherhead Downs, a valley that becomes the finest stretch of the Mole’s scenery about Mickleham, judged by some the fairest spot in Surrey.

Here, too, come the renowned “Swallows” of the Mole, with which its name was rashly connected. This phenomenon is so much insisted on by old writers that one must take it to have been more frequent and on a larger scale in former days. Camden speaks of the river as disappearing for two miles near Mickleham so completely that flocks of sheep could feed over it. In our time it sinks only at points, or is reduced to a chain of pools, after a continuance of dry weather, its current being swallowed up in subterranean recesses, as happens notably in Derbyshire, and most markedly in the Karst region of Austria, taken as the typical stage for this freak performance of nature. An eminent geologist tells us how the chasm which lets the Mole through the Downs is honeycombed beneath by a mixture of broken masses of chalk, interspersed with looser drifts. “The Swallows are evidently nothing more than the gullies which lead to the fissures and channels in the chalk rock beneath. When the supply of water in the river is copious, these hollows will be filled from above faster than the water is discharged below, and the phenomenon disappears. But when the quantity sent down by the river is small, the subterranean channels drain off the water, and the bed of the river is left dry.”

Above the pretty village of Mickleham comes the most glorious bouquet of the Mole, where it makes a grand curve below an amphitheatre of woods, shown from the railway in a tantalising glimpse. The lofty and leafy bank to the west is one face of Norbury Park, that so well displays its noble timber on slopes both gentle and abrupt. Its most celebrated feature is the “Druids’ Grove” of yews, thus described by Mr. L. Jennings:—

The Druids’ walk is long and narrow, with a declivity, in some places rather steep, to the left hand, and rising ground to the right, all densely covered with trees. The yew begins to make its appearance soon after the little gate is passed, like the advance-guard of an army. In certain spots it seems to have successfully driven out all other trees. As the path descends the shadows deepen, and you arrive at a spot where a mass of yews of great size and vast age stretch up the hill, and beyond to the left as far as the eye can penetrate through the obscurity. The trees in their long and slow growth have assumed many wild forms, and the visitor who stands there towards evening, and peers into that sombre grove, will sometimes yield to the spell which the scene is sure to exercise on imaginative natures—he will half fancy that these ghostly trees are conscious creatures, and that they have marked with mingled pity and scorn the long processions of mankind come and go like the insects of a day, through the centuries during which they have been stretching out their distorted limbs nearer and nearer to each other. Thick fibrous shoots spring out from their trunks, awakening in the memory long-forgotten stories of huge hairy giants, enemies of mankind, even as the “double-fatal yew” itself was supposed to be in other days. The bark stands in distinct layers, the outer ridges mouldering away, like the fragments of a wall of some ruined castle. The tops are fresh and green, but all below in that sunless recess seems dead. At the foot of the deepest part of the grove there is a seat beneath a stern old king of the wood, but the genius loci seems to warn the intruder to depart—ancient superstitions are rekindled, and the haggard trees themselves seem to threaten that from a sleep beneath the “baleful yew” the weary mortal will wake no more.

Norbury, like other Surrey parks, had once a special renown also for walnut trees, among which an eighteenth-century owner saw reason to make havoc. At the end of that century the place belonged to Mr. W. Lock, friend and patron of famous artists, by whom the famous “picture room” had its walls and ceiling disguised with fictitious landscape scenes. This paradise is not accessible without permission; but there are rights of way through the park that open some of its sylvan treasures. One, as we have seen, leads above the Mole from Leatherhead. Another from the lodge and bridge at Mickleham runs up the slopes, in front of the house, and through a wood to the hollow below Fetcham Scrubbs, a down on which one can hold south by a path, becoming a road as it passes Polesden Lacy, then beyond winding as a leafy lane on to the thickets and swards of Ranmore Common.

But this beautiful digression would take one out of sight of the Mole and its wide prospects. Fortunate is he who from the brow of Norbury Park can with conscience clear of trespassing look down upon the Mole valley, now ringed in by the richest heights of Surrey—Ranmore, the outskirts of Leith Hill, the woods of Deepdene, Box Hill, and Juniper Hill, among which the river has cleft its way through the ridge of the Downs. Box, juniper, and yew all flourish on the chalk soil; and the lordly parks on these hillsides have fostered a profusion of beeches, chestnuts, cedars, and rarer timber that in the flush of spring or the gorgeous decay of autumn hang like rich tapestry round the green meadows, through which the straight line of the railway makes a chord for the arcs of the river.
