Grimstey Sep. 14. Thursday. Spent the morning at Stone Creek, ten miles north here. Collecting was fairly good in the Cataract just above the Whirlpool sand- stone. The commonest forms are Pleurambrites, Dolonanella elegantula, Rhizophoria circularis, and especially a species of Chrestina. This latter appears at about ten feet above the sandstone and seems widely separated in the dolomite bands up to the first red dolo- mite that is ruffled with the tripleate lyggra. The Chrestina and Orthids are associated and make up regular dense conglomerate in these beds from 3 to 5 miles thick. In the afternoon Jacked the box and shifted it and the contents one via express to New Harren. The Whirlpool sandstone fits into the run-cracks of the Queenston, and is ruffled in smooth and at times irregular ripples. The shales at times also show truncy ripples about 3/8" from crest to crest. These truncy ripples should be looked into to get maximum depth = very shallow, probably less than 20 feet.
