The day after leaving Tan-Yang we entered on the most beautiful part of the river. Great limestone cliffs swing open at times to reveal glorious glimpses, through fantastic gorges, of peaks and ranges, partly forest-covered, fading in the far distance into the delicious blue veil of dreamland; the river, occasionally compressed by its colossal walls, vents its fury in flurry and foam, or expands into broad reaches 20 and even 30 feet in depth, where pure emerald water laps gently upon crags festooned with roses and honeysuckle, or in fairy bays on pebbly beaches and white sand. The air was full of gladness. The loud call of the fearless ringed pheasant was heard everywhere, bees hummed and butterflies and dragon-flies flashed through the fragrant air. What mattered it that our ropes broke three times, that we stuck on a rock in a rapid and hung there for an hour in a deafening din and a lather of foam, and that we “beat the record” in only making 5 miles in twelve hours! The limestone cliffs are much caverned, and near the village of To-tam, where they fall back considerably from the river, we explored one cave worthy of notice, with a fine entrance arch 43 feet in height, admitting into a vault considerably higher, with a roof of stalagmites. We ascended this cavern for 315 feet, and then had to return for lack of light. Near the mouth a natural shaft and rock-ladder give access to a fine upper gallery 12 feet high, only 60 feet of which we were able to investigate. Just above To-tam there is another limestone freak on the river bank, a natural bridge or arch, 127 feet in height and 30 feet wide, below which a fair green lawn slopes up to a height above. The bridge is admirably buttressed, and draped with roses, honeysuckle, and clematis, and various fantastic specimens of coniferæ grow out of its rifts. The beauty of the Han culminates at To-tam in the finest river view I had then ever seen, a broad stretch, with a deep bay and lofty limestone cliffs, between which, on a green slope, the picturesque, deep-eaved, brown-roofed houses of the village are built. The gray cliff is crowned with a goodly group of umbrella pines, in Korea called “Parasol Pines,” because they resemble in shape those carried before the King. Guarding the entrance of the bay are three picturesque jagged pyramidal rocks much covered with the _Ampelopsis Veitchiana_, and of course sacred to dæmon-worship. These sentinels are from 40 to 83 feet high. To the southwest the Han, dark and deep, rolls out of sight round a pine-clad bluff, among the magnificent ranges of the Sol-rak-San mountains--masses of partially pine-clothed peaks and pinnacles of naked rock. To the northeast the river makes an abrupt bend below superb limestone cliffs, and disappears at the foot of Sölmi-San, a triplet of lofty peaks. To-tam on its park-like slopes embraces this view, and were it not for the rapids and their delays and risks, might be a delightful summer resort from Seoul.
