. The Canadian field-naturalist. Wilson: Geology of the Ottawa District 53 Vermes (Plate I, Fig. 1; Plate II, Fig. 10) P. The word 'Vermes' is a general one for worms. There are many divisions and sub-divisions of worm groups. But the general name is appropriate here because there isn't any worm, just a hole where the worm is supposed to have been. No- body knows exactly what kind of worm it was, if any. The Nepean sandstone, the base of the First Invasion deposits, is riddled with these burrows in some places. It is not possible to describe them because they are just hollow, tube-like holes in the sandstone. One good place to see them is south from Eagleson's Corners, the next corner east from Hazeldean. At this corner turn south, and, after passing the first house on the east cross into the second field and follow the long ridge of rock south almost to the old shed. The ridge is formed by the March beds and shows fine examples of the large inclusions of secondary crystalline calcite. Farther south, near the shed, the Nepean sandstone outcrops beneath it, in places filled with these 'worm' holes. After examining the worm holes turn towards the house nearer the road, pass through a gateway into another field and note the sandstone outcrop just beside the fence that lies between the exposure and the barn. The sandstone is made up of great swirls, each with a hard quartzite centre. The beds below are flat, and the beds above, across the field, are flat. Explanations are in order. Several have been suggested but none proved. One possibility is a slump before consolidation, but why the almost uniform size of the quartzite centres, and the uniformity in the size of the swirls ? Another suggestion is that the un- consolidated sand has been pushed by ice on the seafloor. The same objection holds for this theory, and the additional one that no other evidence has been found in- dicating ice'at the Please note that these images are extracted from scanned page images th
