at Limehouse Limestones of the north have now changed to sands, shales, red marl and with the presence of but little lime. At Niagara Falls it is mostly sand with but little lime. I saw no Androtheca plancomera but an abundance of Lep. chromidalis which leads me to regard the Limehous beds as the higher beds seen at Owen Sound. The Niagara ridge can be seen all the way on the west side of the railway going from Gillsgrove or Anandale to Durham from the mountain out of Gillsgrove, Terra Cotta to Limehouse. Left Georgetown at 3.50 pm Toronto.
