Report of progress 1874-1889, A-Z .. . ribed by Prof. Lesquereux (Report J, 1874) theMercer Group at Wirtemburg consists of the successionrepresented on an enlarged scale in Fig. 127. Wirtemburg Limestone, hard and black, 3 Fireclay, 2 Sandstone, 5 Soft greyish shales, 15 Limestone (fucoidal) 1 Coal, 5tol Shale, black soft, with iron ore to water level, 5 to 8 In this vicinity the Homewood Sandstone has thinneddown to a knife edge, and finally disappears, only howeverto reappear again farther up the stream. The Connoque-nessing Sandstone is beneath stream level near Wirtem-burg, but at Rock Point, at the mouth of the Connoque-nessing, it forms rugged perpendicular bluffs one hundredfeet high. Going south and west from Wirtemburg no good devel-opment of the Mercer Group is found. Its place is oftenentirely occupied by the Homewood and ConnoquenessingSandstones which frequently are almost united. At Homewood Furnace the measures have been pretty. thoroughly explored in search after coal and iron ore, but. 190 V. BEPOET OF PEOGEESS. H. M.
