"August 17 Saturday Hamilton, Ont. At the head of Ferguson Ave on the side of the 'mountain' may be seen two sulphur quarries. The lower face is about 35 feet in the man a blue- shale series helow becoming somewhat red at about (Change to about 6-7 feet thick) 2 feet from top and then green with some thin sandstone are turrets that the dolomite offers. below these become more pronounced in the upper 8 feet and about midway in these 8 feet there is a two foot layer of cretaceous material some of the greens 2 to 3 feet wide. It is out of this upper 8 feet that my fossils came from (later it was seen that the lower dolomites come in here) Upon these Medina deposits follow some blue shales in which the dolomitic thin has become more abundant, and finally these dolomites persist until our shales. In these dolomites at first there are but few flat nodules outside at the top they are very abundant. (5 feet seen) This zone is about 20-30 feet thick. In the dolomites above the blue (? siltstone) shales one sees the regular Niagaran fauna of this region: Orthostre, the large me) Colymene, large head of litho delmours or Brumastus the long eyed Acidaspis (near the head) Dolmanites etc. both gave me this fauna as a The M? In the upper flat nodule horizon is where the forages occurs. See the fauna in the N J.H.M.
