This charming form of the sport may be described as combined tobogganing, and in bobbing races teams of four enter against each other. The form of toboggan used is, of course, immensely larger than that employed in single tobogganing, since it will hold five or six persons, and its construction is altogether different and most elaborate. It consists of a long, low platform some 10 feet in length, and is mounted, not on one pair of runners, but on two. The pair that supports the fore part of the bobsleigh is a sort of bogie-truck, pivoted under the platform, and it can be turned to the right and left in order to direct the course of the bob round curves. This turning of it is done by the captain, who sits first at the bows of the sleigh, and is worked by ropes, which he holds in his hands, or by a wheel which controls its movements. In long runs, as on the Schatz-alp at Davos, the wheel is far better than the ropes, since it entails so much less strain on the hands of the steersman: on a short run the ropes are as good. Behind the captain sit the members of his crew in line, with the loops of rope just outside the framework of the sleigh, in which they fix their heels. Last of them all sits the brakesman, at the stern of the sleigh, who has in his control a powerful steel-toothed brake, which crosses the sleigh behind and is worked with levers. But it is the captain who is in command of the bob, and the brakesman and other members of the crew only perform his orders. The word “bobsleigh” is derived from the movement of leaning or “bobbing” forward, which is done by all the crew together, to get up speed or increase it. They come forward quickly with a jerk, and go back again slowly and steadily, and this without doubt accelerates the movement of the sleigh.
As in all other forms of tobogganing, braking is employed to diminish speed in coming to corners, where otherwise the momentum would cause the whole concern to leave the track altogether. So also, just as the ice-tobogganer inclines his body inwards in a similar position, the captain and crew lean to the inside of the track when going round a corner so as to help the toboggan round it, while the inclination of the front pair of runners is directed to the same end. By strong leaning inwards, combined with the inclination of the bogie-pair of runners, quite considerable curves may be taken at high velocity without the use of the brake at all, and the consequent loss of speed. But all this is left to the judgment of the captain, who has to decide whether by direction of the bogie-runners alone, or by that in conjunction with the leaning inwards of his crew, he can safely negotiate a corner without calling for the use of the brake. And the responsibility is entirely in his hands. At the same time much depends on the prompt obedience of the crew to his orders, for it is easily possible that a corner might have been safely coasted round if they had obeyed his call to lean inwards, which would spill them all if his call was not immediately responded to. How great the effect of this inward shifting of the weight can be, if it is thoroughly carried out, may be guessed from Plate XXXI. In this same photograph the inward direction of the front pair of runners may also be seen assisting the work of the crew. And it is this “teamwork,” the sense of working in unison under orders, which gives much of its charm to bobbing. Everyone feels—rightly—that much of the success of the run depends on his individual work, even though his individual work is only to lean as far as possible out of the bob without parting company with it altogether.
Bobbing can be practised on an ordinary road covered with hard snow, or, in excelsis, on runs constructed for this express

purpose. Of these the two most famous are the St. Moritz bob-run, which starts by the Bandy rink and finishes side by side with the Cresta ice-run, after passing under the railway bridge, and the Schatz-alp run at Davos. Previous to its construction, not many years ago, bobbing at Davos chiefly took place on the Klosters road, which was the same track as that used by the ordinary toboggan, but now each has its own course. These artificially constructed bob-runs are engineered with the same care and nicety as ice-runs for the single toboggan, and at corners curved banks are built solidly of beaten-down snow. The track is then iced, for no snow could stand the continual passage of the heavy bobs over the same banks and narrow course without speedily being worn into ruts that would entirely spoil the going and upset the goers, and the ice is then sprinkled over with loose snow to prevent the toboggan skidding. But the greater part of bobbing is done on the public roads, which are frozen and hardened by the passage of sleighs. At most Swiss winter resorts there are facilities for this delightful form of sport.
