20According to the 1904 Coal Report (page 340), the air and escapement shaft construction was to begin after the hoist shaft was completed in mid-October of 1904, and this shaft was to be 8 feet by 13 feet. No shaft other than the hoist shaft could be discerned on the source maps. This shaft is not shown on the accompanying map, but all mines were legally required to have another place of egress for the miners’ safety, and presumably another shaft did exist.
