LETTEK OF TRANSMITTAL. 



E. W. Brock, Esq., 



Director Geological Survey, 

 Department of Mines, 

 Ottawa. 



Sir, — I beg to submit herewith a memoir on the geology of 

 Steeprock lake, Ontario ; together with notes by the Hon. Charles 

 D. Walcott, on certain fossils found in the limestone of the same 

 area, which have a peculiar interest in that they are apparently the 

 oldest forms of life yet discovered. 



I have the honour to be, sir. 



Tour obedient servant.
