34 JOURNAL AND PROCEEDINGS 



It is asserted that many of the flint implements discovered in 

 New Jersey and other places in the " States " were obtained from 

 superficial gravels, (not true glacial drift). I noticed some years 

 ago, part of the rib of a Mastedon (probably) in a " Slab-town " 

 gravel pit ; but as yet I failed to procure any flint or other imple- 

 ments either there or at Burlington Heights. It was in making the 

 excavation for the Desjardin's Canal that the bones of a mammoth 

 jaw of a Beaver, and horns of the "Wapiti " were found. Although 

 the Canadian Geological Survey, in Sir William Logan's time, noted 

 that the Erie clays underlie the gravels, Burlington Heights, at the 

 Desjardin's Canal, I can find no record of their overlying our local 

 glaciated chert on the Niagara escarpment here. This circum- 

 stance probably escaped observation. I think it has an important 

 bearing on the ill-understood superficial geology of this district. 



The clay containing rounded transported Laurentian pebbles, 

 fills up the grooves made by glacial action, and can be easily dis- 

 tinguished from the mere surface soil above it. I have placed in 

 one of the side cases of the Museum a specimen for examination.
