Special Localities of Fossil Plan 



rs. 



The plants referred to in Professor Penhallo.w's paper are derived in part 

 from deposits belonging to each of the columns in the above table. 



(1.) At Green's creek, on the Ottawa river, the Leda clay, there contain- 

 ing marine shells (Leda aretica, etc.) and bones of Capelin in nodules in the 

 clay, has in its lower part nodules with leaves, seeds, and fragments of wood. 

 These have been collected by the late Mr. Billings, Dr. R. Bell, the late 

 Sheriff Dickson, of Kingston, the late Mr. J. G. Miller, and the writer, and 

 were noticed in a paper by the writer on the " Evidence of fossil plants as to 

 the climate of the Post-Pliocene in Cauada," published in the Canadian 

 Naturalist in 1866. These constitute a considerable part of the specimens 

 described below. A few specimens of wood have also been found and noticed 

 by the writer in the Leda clay of Montreal, and the available collections 

 have been augmented since 1866 by additional specimens from Green's creek 

 acquired by the Peter Redpath Museum of McGill University. 



(2.) The interesting deposits at Scarboro' heights and elsewhere on Lake 

 Ontario were described by Dr. J. G. Hinde in the Canadian Journal in 

 1877, and he notices the following plants as found by him : 



Wood of pine and cedar. 



Portions of leaves of rushes, etc. 



Seeds of various plants. 



Hypnum commutatum. 



H. revolvens. 



Fontinalis. 



Brywn. 



Chara, sp. 



More recently Mr. J. Townsend, of Toronto, was -so fortunate as to find 

 leaves and fragments of wood with shells of Melanin and Cyclas, in beds 

 apparently of the same age, in excavations in progress on the River Don, at 

 Toronto. These collections have been acquired for the Peter Redpath 

 Museum. The section observed at this place is given as follows by Mr. 

 Townsend : 



The locality of the principal vegetable specimens was 150 feet from the 

 bank of the Don, and in a cutting 70 feet deep. The section showed 26 feet 

 of fine light-colored sand with layers of clay at bottom. Below this were 24 

 feet of tough stratified blue clay, the " Erie clay" of the region. At the 

 base of this clay is a seam of reddish ferruginous sand about three feet thick, 

 and with argillaceous nodules in which was the maple leaf described by 

 Professor Penhallow. Below this sand were sixteen feet of alternating sand 

 and dark-colored clay, with fresh-water shells and wood. Below this was 

 the blue till resting on the surface of the Hudson river beds. In this section
