covered with snow, and there being several large glaciers.
"During last year, before the line was opened for traffic, observations were taken with the view of ascertaining what trouble might be anticipated from avalanches, the avalanch paths through the Selkirks being very numerous. Several large avalanches occurred, the largest covering the track for a length of 1,300 feet, with a depth in one place of 50 feet of snow, and containing, as was estimated, a quarter of a million cubic yards of snow and earth. The result of these observations caused the Company to construct during this season four- and-a-half miles of snow sheds, at a cost of $900,000, or $200,000 a mile. "The sheds are constructed as follows:--On the high side of the mountain slope a timber crib filled with stones is constructed. Along the entire length of the shed, and on the opposite side of the track, a timber trestle is erected, strong timber beams are laid from the top of the cribwork to the top of the trestle, 4 feet apart and at an angle representing the slope of the mountain, as nearly as possible. These are covered over with 4-inch planking, and the beams are strutted on either side from the trestle and from the crib. The covering is placed at such a height as to give 21 feet headway from the under side of the beam to the centre of the track. The longest of these sheds is 3,700 feet, and is near the Glacier Hotel. "Over the Selkirk Range the schedule time for trains from Donald to Revelstoke, that is, from the first to the second crossing of the Columbia River, a distance of 79 miles, is only eleven miles an hour; but this time table was made before there was much ballast on this portion of the line, and better time can now be made.
