thought of; descent in such cases is always far more dangerous and troublesome. It was fortunate that in crossing twice or thrice the waterfall itself, we were not pumped on to any serious extent. I was moistened only, being garnished with a Macintosh; and I have only two scars now left on my shins, the result of scraping too close an acquaintance with sundry rocks. The whole affair lasted between three and four hours. I cannot recommend it, save to very enthusiastic mountaineers, or to _ci-devant jeunes hommes_ anxious to test the effects of Time upon their powers of walking and of endurance. Regaining the hurricane-deck of the Tip-top House--for the roof is the principal promenade, and often times assuredly deserves the name I give it, how gratefully, as the sun went down, stole the sense of ineffable grandeur over the somewhat wearied frame! It was a superb evening; and though it would not suit me to cull a leaf from the Guide-book, and tell all that is therein narrated, I must mention one particular wherein this locality is notable, if not quite unique. I think I remember something of the kind, but not so marked, at sunrise as seen from the summit of Etna; but not thus, on the Righi and Faulhorn in Switzerland, on the Pic du Midi de Bigorre in the Pyrenees, or on other peaks that I have climbed in the days of long ago, to salute the coming or speed the parting day. The nearest approach to it that I have seen, was at the Great Pyramid of Ghizeh. I allude to the wonderful distinctness and regularity with which the shadow of the great cone itself is traced, at sunset, striding over heights and lowlands, mound and lake--all the intervening surface, in fact, between the spectator and the far distant horizon--until it contracts almost to a point where earth and sky merge into one. The sharpness of these converging parallel lines of shadow in that luminous atmosphere absolutely astounded me. They were as crisp, as clearly defined, as those that you may see in antique pictures of Jacob's Dream, leading ladder-wise from Heaven to the head of the slumbering Patriarch. Sunrise, next morning--for I was again favoured with clear weather and only sufficient frost to render the roof of the restaurant slightly slippery--sunrise, I say, reserved all this. The narrow lines, now on the Western horizon, broadened out and came upwards and forwards, as in the evening they had elongated and gone down. It was in truth a rare spectacle, not to be forgotten, and individualizes this natural observatory.
