The axis ofthe range, therefore, lies to the west of the station, and the beds mustsink as we go south, for the southern part of the range is made up ofthe limestones that he above these quartzites. Station 78, just southof 77. is on the micaceous slates that lie below the quartzites and chlo-ritic slates. It is a couple of hundred feet higher than Station of Station 78 a long ridge connects the northern portion of therange with the southern, on which Station 135 was located. Station 135 is on limestones that are probabl
