“The Subway is about 10 to 15 feet wide and from 7 to 2 feet high; the roof is arched and covered by moisture drops, which are very unpleasant when they find their way down your back. The floor is of broken rock, rising to a ridge along the centre of the passageway. “From the meeting of the ways, just beyond the Art Gallery, the passage continues southeasterly, ever increasing in interest. In the next 200 feet, it varies in width from 15 to 30 feet with a height of 10 to 15 feet. On the right is a narrow twisting side-opening named ‘The Gimlet.’ On the left are two concave sections of old potholes, leading into the most subterranean depths. They are profusely decorated by florescent carbonate incrustations, the first one being named ‘The Dome’ from its perfect formation. Minor passageways lead from them at a still greater depth. The most southerly one connects with ‘Judgment Hall,’ to be described further on (see map). In this section the underground course of Cougar creek crosses the corridor, at a considerable depth below, and the roar of the hidden waters is transferred from the left to the right hand. “A narrow opening, 1½ feet wide and 15 feet long, now leads to ‘Carbonate Grotto’ where are seen very fine calcium decorations. The Cavern containing the grotto is about 60 by 30 feet, with a height varying from 10 to 15 feet. For the next 130 feet the passage varies from 8 feet wide and 5 feet high at the upper end to 20 feet wide and 5 feet high at the lower end. The sides are hung with rock shelves, and spotted with lime incrustations; the bottom is much impeded by fallen blocks. You now find yourself in a cul-de-sac and apparently at the end of the series. Not so, however, for by squeezing through a narrow opening on the right, barely noticeable in the darkness, you are enabled to descend to probably the largest cavern of all, at a depth of 57 feet below the corridor just left. The chamber, 200 feet long, 20 feet wide and 40 to 50 feet high has been named ‘Judgment Hall,’ on account of a pillar which might stand for the pillar of justice. The floor is littered by blocks broken from the roof and sides which lie piled in great heaps at the north end. The roof is roughly arched, and the sides rise upwards in parallel ledges resembling shelves. Roof, sides, and the rocks piled on the floor, are covered by the white calcite and, in many places, present most beautiful patterns and beds of florescent formations. The north end is connected by a rough passage with one of the potholes referred to below the meeting of the ways.
