Inglewood to Falls of Credis and for 3 miles further to Cataract Junction. It's a pic- turesque rally and all about Falls of Credis may be seen the quarries in the Clinton. It is interesting to note that the upper green shales of the Clinton are at Cataract 15 to 20 feet thick while at Linehouse there is only 6 feet. In a so that a distance I should think that the difference is due to erosion. The break between the "Clinton" and the Lockport is as long as the Roches- ter and a fair bit less of the Clinton.
