[D 2542] Grand Breve formation. In the afternoon searched the hills along the 'Portage' through the corral to the cliffs. Saw no fossils in the cliffs which I judge to be Lygaeo grapt. On the hills on both sides of the Portage saw almost no fossils but did find Lep. concharia and a Odmunicl? taut. This is June 6. Later examined more closely the position of the Rhyne, hamandei beds and found them to be in the yellow thin bedded limestone which usually agrees as the Chonite came down, beds are one foot thick. In the brook where we collected this Chonite it is not more than 20 feet thick; the hamandei beds are probably not less than 20 feet. These beds of a whitish and more crystalline nature with its large fossils are probably not less than 20 feet thick. Later. This Crystallany zone is clearly in mor? and probably some distance from the top. See Skiffs field remarks.
