in the Camelian form. A. larlani also occurs. This molled sandstone with many grms of shale pebble mclusing is about 6 ft thick. Beneath it appears still distier mottled red sandstone and red sandy shales. One sees the A: aechimids (Camelias) in one of the sandstone down in 20 ft beneath the greyland. At about from 25 to 45 ft beneath the top is a zone of decidedly heavy bedded sandstone that are mud and cns bedded. Through this zone I saw no Carchophyces thank they may occur towards the top where there are thinner shale beds. Beneath in about 40 ft, sandy shales predominate when another sandstone zone (tending to be oily) comes in for a thickness of 10 ft. Clarke gives the Medding exposures as 75 feet certainly at 60 and perhaps while Shurtzapel places it at 95 feet. Lockport. At the upper face of the Seneca one can see the contacts between the Lockport and Rochester. I could not get near enough to make out the nature of the contact but no ordinary rolled concentric cement beds appear to occur here. There appears
