He pointed out because the pteris Equisitae were found in the tropical regions therefore all Carbon Floras must have been tropical. But he thought not that undoubted physical evidence was at hand in the various glacial beds that we were on the road to a final explanation and determin- [illegible] of former glacial causes. However he advised cautious and he hoped the pendulum would not swing too far the other way. Coleman also thought from what he saw in Africa that no high lands existed during the Perno-Carbon glaciation. Furthermore he did not think that high altitude was necessary to ice accumulation as we had a good example in the Antarctic ice cap. At zero no snow accumulates in fact it vanishes here faster than accumulates due to evaporation. He also announced that he had in several state mining reports pointed out that a seemingly fold line had occurred in the Cana- dian Lower Devonian. It resembled the deposits conglomerates of Africa. He could not make this announcement as yet positive as he
