GEOLOGICAL NOTES. 



Read before the Geological Section of the Hamilton Association, Nov. 22nd, 1896, 



BY COL. C. C. GRANT. 



The recent visit of Prof. Chas. Schuchert, Curator of the 

 Paleontological Department, National Museum, Washington, U. S. 

 A., author of an able paper on the "Classification of the Brachio- 

 pods," induces me to think that a short account of our proceedings 

 here and at Grimsby may not prove altogether uninteresting to the 

 geological section of the Hamilton Association. I was about to 

 leave for Winona when I received Dr. Gurley's letter informing me 

 the curator was proceeding on a collecting tour, and intended to pay 

 Hamilton a visit. His arrival seemed so uncertain, I went on, leav-

 species of Graptohtes, and giving directions to let me know at once, 

 if he called during my absence. I ascertained on my return he 

 arrived the day before, got the fossils, and had gone to Toronto, but 

 was to be back in a day or two. When he returned on Monday, I 

 took him to " The Hamilton Museum," after we selected some spec- 

 imens from my private collection. He passed a considerable time 

 in examining our characteristic local fossils, the Clinton ones espec- 

 ially Arthroclema, an undescribed species, probably the colored 

 Lingulse, Dr. Jas. Hall's Posidonia, and the plants of the series. 

 On coming to the case containing the Niagara specimens, he re- 

 cognized some of the Tennessee Sponges we obtained from Dr. Head, 

 Chicago. He stated they are so numerous there, you may collect a 

 bushel of them in a day. Sections of the Hamilton Sponges formerly 

 were equally numerous, but the localities are limited and many 

 thousands have since been taken away. I pointed out a few slabs 

 from the Niagara Shale at Grimsby, and stated if he could spare time 

 I thought he would find the quarries there highly interesting. The 

 Shales possessed many well preserved Crinoids or Sea Lilies, and
