The advantage of the artificial slide is that it can be kept constantly in order, and therefore may be in first-class condition for sliding when the snow is altogether too soft and deep upon the hills. These slides are to be seen in every part of Canada, their gaunt framework rising up tall and stiff out of some level field, or, better still, upon a hill-top, thus securing a double elevation. They are roughly yet strongly constructed of beams and boards, and comprise one, or sometimes two, long troughs placed side by side, with a flight of stairs adjoining. These troughs are curved in the shape of a cycloid, and are from three to five feet wide, the length, of course, varying with the height of the structure. When winter has finally set in they are paved with big blocks of ice from bottom to top, over which loose snow is scattered, and then abundance of water poured on, until, Jack Frost kindly assisting, the whole is welded together into one solid substantial mass. A slide once properly prepared, and kept in order by the addition of a little more snow and water now and then, will last all winter; and the more it is used, the faster and truer it becomes. In the grounds of Rideau Hall, the official residence of the Governor-General of Canada, there are two immense slides, and tobogganing may there be enjoyed in full perfection. Let us suppose we have been invited to one of those brilliant torchlight fêtes which form so popular an item in the programme of the viceroy’s winter hospitality. A more beautiful scene than that which lies all around and underneath us, when we have accomplished the toilsome ascent of the steep, slippery stairs of the toboggan slide, can hardly be imagined. Stretching away from the narrow platform upon which we stand, two long double lines of flaring torches mark out the slides, slanting sharply downward until they reach the level far below, and then run off to hide their endings somewhere in the dusky recesses of the forest. At our left another line of torches, interspersed with Chinese lanterns, encircles a gleaming mirror, upon whose surface the skaters glide smoothly this way and that, while from its centre—looking oddly out of season, it must be confessed—a Maypole flaunts its rainbow ribbons. A little further on, the long, low curling rink, gaily decorated, proclaims good cheer from every lighted window. Turning to our left, we catch through the trees a glimpse of the other skating pond, with its ice palace for the band and quaint log hut for tired skaters. Right in front of us a huge bonfire blazes up, making music with its merry crackling. But we have lingered too long in taking all this in. We are stopping the way, and an impatient crowd is pressing hard upon us. Let us place our toboggan, then, carefully in the centre of the groove, adjust the cushions, coil up the cord, and seat ourselves securely, with stout grasp upon the hand-rail. "All ready?" cries the steerer. "Ay, ay!" we reply.
