One element of mountain beauty is, we shall all admit, their vast size and steepness. That a mountain is very big, and is faced by perpendicular walls of rock, is the first thing which strikes everybody, and is the whole essence and outcome of a vast quantity of poetical description. Hence the first condition towards a due appreciation of mountain scenery is that these qualities should be impressed upon the imagination. The mere dry statement that a mountain is so many feet in vertical height above the sea, and contains so many tons of granite, is nothing. Mont Blanc, is about three miles high. What of that? Three miles is an hour's walk for a lady--an eighteen-penny cab-fare--the distance from Hyde Park Corner to the Bank--an express train could do it in three minutes, or a racehorse in five. It is a measure which we have learnt to despise, looking at it from a horizontal point of view; and accordingly most persons, on seeing the Alps for the first time, guess them to be higher, as measured in feet, than they really are. What, indeed, is the use of giving measures in feet to any but the scientific mind? Who cares whether the moon is 250,000 or 2,500,000 miles distant? Mathematicians try to impress upon us that the distance of the fixed stars is only expressible by a row of figures which stretches across a page; suppose it stretched across two or across a dozen pages, should we be any the wiser, or have, in the least degree, a clearer notion of the superlative distances? We civilly say, "Dear me!" when the astronomer looks to us for the appropriate stare, but we only say it with the mouth; internally our remark is, "You might as well have multiplied by a few more millions whilst you were about it." Even astronomers, though not a specially imaginative race, feel the impotence of figures, and try to give us some measure which the mind can grasp a little more conveniently. They tell us about the cannon-ball which might have been flying ever since the time of Adam, and not yet have reached the heavenly body, or about the stars which may not yet have become visible, though the light has been flying to us at a rate inconceivable by the mind for an inconceivable number of years; and they succeed in producing a bewildering and giddy sensation, although the numbers are too vast to admit of any accurate apprehension.
