Colour.
The colour of the ski is very largely a matter of taste, and in nine days out of ten is of no practical importance. Every now and again, however, there will be a time when the sun will beat fiercely on dark-coloured ski and warm them, causing the snow to adhere to them top and bottom more readily than to those of lighter colour, which throw off a greater proportion of the rays. For which reason we unhesitatingly give our vote for plain varnished or white-painted ski. Black-painted ski are, however, very common in Norway. They look very smart and present a pleasing contrast to the snow, and they are frequently recommended for mountain use, for the reason that when the eye is dazzled by vast expanses of unbroken white they afford a valuable point of focus, and so act as a preventive to snow-blindness. We would, however, strongly advise the reader not to rely too much on this, or sooner or later his eyes will surely be affected. Smoked goggles, or some such arrangement as that recommended on page 50, are infinitely preferable to any black paint. Besides which, plain varnished ski are ever so much darker than the snow, and one can focus one’s eyes almost equally well on them. The painting of ski is, on the other hand, often a cunning device on the part of unscrupulous dealers to hide defects in the wood—a fact which may account for their popularity to a greater extent than the guileless may suppose.

Having, then, given our vote for plain-varnished, flat-topped, fairly heavy ash ski of Telemark type, with a long, easy, flattish elastic entrance and a broadish point, it remains for us to consider how broad they shall be at the middle and how long over all, and whether they shall or shall not be provided with a groove underneath them running from end to end. We approach these questions with a certain degree of diffidence, for, in the first place, investigations with a view to their answer have not been, and perhaps cannot be, carried out with much scientific precision, and, in the second place, they will always remain very largely matters of personal taste.
Smooth-bottomed and Broad versus Grooved and Long.
Evidently to some extent the length and breadth of a ski must be proportionate to the weight of the runner, a certain degree of carrying surface being necessary to obviate sinking. But, apart from all questions of support, length is of great importance. In this respect ski resemble ships, for, generally speaking, the longer they are the faster they go. Area for area long ski are faster than broad. On the other hand, the shorter a ski is the more readily it will turn, and it is, of course, very important to be able to steer easily. There comes a point, however, when ease of turning develops into wobbling, and seriously interferes with one’s balance when running straight. Nor is the unsteadiness of short and broad ski confined to what may be considered as horizontal wobbling, due to inequalities of the ground, but broad ski are also more subject to what may be regarded as vertical wobbling, due to unequal snow consistency. For in the case of the long ski variations in the carrying power of the snow and consequent errors of balance occur in a backward and forward direction, but in the case of a broad ski in a sideward direction, which latter is, of course, more upsetting.

Again, almost all ski are nowadays provided with a groove along the bottom, beginning at a point a little distance below the bend and continuing to the heel. The object of this is to prevent horizontal wobbling and to assist straight running. Its working is most powerful. Clearly, then, some sort of compromise must be arrived at between a very smooth and broad ski on the one hand, and a very long and grooved one on the other. Now in Norway straight running is all the order of the day. Around Christiania there is scarcely a hill which cannot be, and is not, taken at full speed, and the smooth, glacier polished mountains of that country are equally suitable for a straight descent. In the Black Forest, too, straight running is paramount. For these countries we recommend grooved ski about as long as the distance between the ground and the roots of the fingers when the hand is held above the head, and of a width proportionate to the weight of the runner. In Switzerland, however, the ground is both steeper and more irregular, and in general far more difficult for straight running, hidden water-courses, rocks, and other obstacles being of common occurrence. There, it is accordingly of paramount importance to the beginner to be able to control his speed and to turn, and our advice is that in that country he should, for ordinary going, use somewhat shorter and slightly broader ski—say, about 6in. shorter than in Norway. We advise him for all-round purposes in Switzerland to retain the groove. But if he is going to do much climbing on very steep and difficult ground, or if he is advancing in years and has lost something of his pristine dash, he may find it convenient to omit the groove and to travel on perfectly smooth boards.
