The New Student's Reference Work/Sarnia, Can.

Sar′nia, Can., stands where St. Clair River issues from Lake Huron.  The submarine tunnel connecting the railway systems of Ontario with those of Michigan is here.  Steamers leave Sarnia twice a week for Duluth.  There is ferry-communication with Port Huron (Michigan).  The oil-refineries, saltworks and lumber are extensive industries.
