the right, and commenced the ascent.
It is one among the prevailing fallacies of the times, that to mount a Highland hill is a very difficult operation, and that one should hire a guide on the occasion. We lately witnessed a very distressing instance of the alarming prevalence of this notion, in a young Chancery barrister, fresh from Brick Court Temple, who asked us in a very solemn tone of voice, if we could recommend him to "a steady guide to the top of Arthur Seat." When matters have come to such a crisis, it is time to speak out; and we are able, on the ground of long experience, to say, that if the proper day be chosen, and the right method adopted, the ascent of our grandest mountains is one of the simplest operations in all pedestrianism. True, if people take it in the way in which pigs run up all manner of streets, and go straight forward, looking neither to the right nor to the left, they will run their heads against nature's stone walls, which are at least as formidable as man's. But let any one study the disposal of the ground, calculating the gradients and summit levels as if he were a railway-engineer for the time being—let him observe where the moss lies deep, and precipices rise too steep to be scrambled over; and he will be very obtuse indeed, if he is not able to chalk out for himself precisely the best way to the top. It is a good general rule to keep by the side of a stream. That if you do so when you are at the top of a hill, you will somehow or other find your way to the bottom, is, we are convinced, a proposition as sound as Newton's theory of gravitation. But in the ascent, the stream is often far better than a human guide. It has no interest to lead you to the top of some episodical hill and down again, and to make you scramble over an occasional dangerous pass, to show you how impossible it is that you could have found the way yourself, and how fortunate you are in having secured the services of an intelligent and intrepid guide. On the contrary, as long as you keep by the side of the stream you are always gaining ground and making your way towards the higher levels, while you avoid bogs: for the edge of a stream is generally the dryest part of a mountain.
Choosing the broadest and deepest scaur that is scratched down the abrupt side of the lower range of the mountain, we find it, as we anticipated, the channel of a clear dancing stream, which amuses us with its babble for several hundred feet of the ascent. Some time ere we had reached the base of the hill we had lost sight of the summit, and there was before us only the broad steep bank, with its surface of alternate stone and heather, and a few birch-trees peeping timidly forth from crevices in the rock. After a considerable period of good hard climbing, accompanied by nothing worthy of note either in the variations of the scenery or in the incidents encountered, we are at the top of this rampart; and behold! on the other side of a slight depression, in which sleeps a small inky lake, the bold summit of the mountain rises clear and abrupt and close, as one might see the dome of a cathedral from the parapet on the roof. Here we linger to take a last look of the objects at the foot of the hill, for ere we resume the ascent we shall lose sight of them. Already Fort William looks like a collection of rabbit-houses. The steam-boat on the lake is like a boy's Christmas toy. The waters have assumed that hard burnished metallic appearance which they convey to the eye raised far above them in a hot summer day. The far-stretching moss, with one or two ghastly white stones standing erect out of its blackness like druidical remains, carries the eye along its surface to the dusky and mysterious ruins of Inverlochy Castle, which has so sadly puzzled antiquaries to divine how its princely round towers and broad barbican could have been erected in that wild and remote region, where they stand patiently in their ruined grandeur, waiting till our friend Billings shall, with his incomparable pencil, make each tower and arch and moulding as familiar to the public eye as if the old ruin stood in Fleet Street.
Off we start with the lake to the left, taking care to keep the level we have gained. A short interval of walking in a horizontal direction, and again we must begin to climb. On this side the porphyry dome is round and comparatively smooth—scarcely so abrupt as the outer range of hill which we have just ascended. But wending north-eastwardly when near the summit, we came suddenly to a spot where a huge fragment of the dome had, as it were, been broken off, leaving a ghastly rent—how deep it were difficult for the eye to fix, but the usual authorities tell us that the precipices here are 1500 feet high. When we reached their edge, we found that the clouds, which had been completely lifted up from the smoother parts of the mountain, still lingered as if they had difficulty in getting clear of the ragged edges of the cavernous opening, and moving about restlessly like evil spirits, hither and thither, afforded but partial glimpses of the deep vale below. Though Ben Nevis was at this time rather deficient in his snowy honours, considerable patches lay in the unsunned crevices of the precipice. It was a fine thing to occupy one's-self in tilting over huge boulders, and to see them gradually approach the edge of the gulf, and then leap thundering into the mist.
Turning our eyes from the terrible fascinations of the precipice to the apex of the hill now in full view, a strange sight there met our eyes—a sight so strange that we venture to say the reader no more anticipates it than we did, at the moment when we looked from the yawning precipice to what we expected to be a solitary mountain-top. "Pooh!" the reader will say, "it was an eagle looking at the sun, or a red-deer snuffing with his expanded nostrils the tainted air." We shake our heads. "Well, then, it was a waterspout—or, perhaps, a beautiful rainbow—or something electric, or a phenomenon of some sort." Utterly wrong. It was neither more nor less, reader, than a crowd of soldiers, occupying nearly the whole table-land of the summit! Yes, there they were, British troops, with their red coats, dark gray trousers, and fatigue caps, as distinctly as we ever saw them in Marshall's panoramas! We were reminded of the fine description which Scott gives of the Highland girl who was gazing indolently along the solitary glen of Gortuleg on the day of the battle of Culloden, when it became suddenly peopled by the Jacobite fugitives. "Impressed with the belief that they were fairies—who, according to Highland tradition, are visible to men only from one twinkle of the eyelid to another—she strove to refrain from the vibration, which she believed would occasion the strange and magnificent apparition to become invisible." But whether the eye winked or not, there they were—substantial able-bodied fellows; what could it mean? Had Colonel Mitchell discovered a new system for protecting the country by fortifying the tops of mountains which an enemy never comes near? Could it be some awkward squad sent to be drilled on this remote spot that it might escape the observation of the sarcastic public? Such were the theories as suddenly rejected as they were suggested. It was vain to speculate. No solution we could devise made the slightest approach to probability; and our only prospect of speedy relief was in pushing rapidly forward. A very short sentence from the good-humoured looking young fellow who received our first breathless and perplexed inquiry, solved the mystery,—"did you never hear of the Ordnance Survey?" Yes, indeed, we had heard of it; but our impression of it was as of something like a mathematical line, with neither breadth nor thickness; but here it was in substantial operation. The party were occupied in erecting a sort of dwelling for themselves—half tent, half hut. Though in fatigue dresses, and far from being very trim, it was easy to see that they were not common soldiers. They belong, we believe, to the educated corps of sappers and miners; and a short conversation with them showed that the reputation of intelligence and civility long enjoyed by that distinguished body has not been unjustly earned. Though not blind to the magnificence of the panorama of mountain, lake, and distant far-stretching forest-land that lay beneath our feet as we conversed, they did not conceal their consciousness that the prospect of passing some months on such a spot was not particularly cheering to round-cheeked comfortable Englishmen, accustomed at Sandhurst and Addiscombe to comforts even superior to those of the Saut Market. The air was unexceptionably pure and abundant—yet the Bedford level might have been preferable as a permanent residence. Many were the reflections that occurred to us of the feelings of a set of men thus cut off from the earth, down on which they looked, like so many Jacks on a huge bean-stalk. What a place to encounter the first burst of the November storm in, beneath the frail covering of a tent! How did their friends address letters to them? Would a cover addressed "Mr Abel Thompson of the Royal engineers, Top of Ben Nevis," be a document to which the post-office would pay any more regard than to a letter addressed to one of the fixed stars? Could they ask a friend to step up to dinner, or exchange courtesies with the garrison of Fort William, into whose windows they might peep with their telescopes?
In the course of conversation with our new friends, we alighted on a subject in which we have long taken an interest. They had already conducted some operations on Ben Muich Dhui, and they were now commencing such surveys on Ben Nevis,
