Track.

The track, if possible, should be a straight 100 yards. If the work is done inside it is necessary to work on the circular track or on the floor of the gymnasium. A cinder track is the most desirable if it can be procured. First the earth is dug up, then mixed with coarse ashes; the earth and coarse ashes are then packed down; fine ashes are mixed on the top layer. The whole track is then wet thoroughly and rolled until level and smooth. The track is generally divided into lanes, three feet six inches in width, and is made wide enough to have four lanes.
