the Jolly Cut road and especially back of a low one story building near the Stmo Cruster. As we could continue here see the lower Catarack beds are marked still further west or north to the Mountain View House at the head of another inclined plane. Here along the steps down the hill may be seen the lower part of the Lockport resting on the Medina. At the level of the reservoir tidal and at the base of the steps are saw the basal Catarack limestone and one are said to have a thickness of 70 feet without seeing the basal sandstone which is 6 feet thick at Grimsby. At Grimsby we made out the thickness of the Catarack formation to be 70 feet. Left Hamilton for Toronto at 7:05 P.M. A very profitable day. The Cataracs formation is established and lies below the Medina formation.
