 At Burke Point (No. 3) is a groove 22 feet wide and 20 inches deep, rising out of the water S.W. for a distance of 70 feet over a steep, polished and scratched surface, at an angle of about 40° to the horizon ; in this groove there are two sets of scratches, one in the direction of the groove, the other, and more recent one, in a direction N. 31° E. On Campbell's Hill (No. 4) there are numerous boulders, many of them curiously poised. At Cat Point (No. 5) there are grooves on perpendicular surfaces just above the level of the sea, very similar to those occurring on the Blue Hills (No. 6), at a considerable altitude. The west side of Signal Hill, north of St. John's Harbour (No. 22a) has the surfaces of the highly inclined strata of coarse sandstone smoothed, grooved, and scratched at all angles of inclination. The marks are lost at the eastern edge of the hill, which forms a precipice 300 feet high, bounding a valley 1000 feet wide, running N.E. and S.W., and they reappear on the opposite boundary of this valley, which rises about 80 feet, and consists of highly inclined strata of coarse conglomerate. After passing over about 1000 feet of this conglomerate, the marks disappear at the sea- shore.

North of Bonavista Bay the granite has the rounded appearance of a glaciated region ; but the rock is easily weathered, and the scratches had to be sought under perched blocks. On Ladle Island (No. 23) there is a groove 10 feet wide and 12 inches deep, extending completely across the island (a distance of 200 yards). The surface of the island is formed by the edges of highly inclined beds of schist.

The author discussed the extent and effects of the glacier-system to which these markings are due, and indicated that its great terminal moraine is probably the 80-fathom bank across the mouth of Conception Bay, and that smaller terminal moraines exist in the form of submerged banks at the entrance of Holy-rood and Collier's Bays. He expressed the opinion that the country has not been submerged since its glaciation, and considered that the assertion that it is now rising is exceedingly doubtful.

The paper was illustrated with numerous drawings of localities and rubbings of scratched surfaces.
