NORTHERN, SOUTHERN AND SALINE PLANTS IN CANADA. 47 
Coues, in his “Birds of North America,” says that the winter home of this grebe is on 
the Pacific coast, and specimens of the Plantago obtained on Vancouver Island by Dr. 
George M. Dawson are identical with those obtained by myself at the head of Lake Win- 
nipegosis. 
My localities for Ruppia and Plantago are the only ones known in the interior of the 
American continent and in both cases the birds which could have brought the seeds were 
breeding in the neighborhood. 
Did time permit, I could show by numberless instances that certain species of water- 
fowl always migrate on fixed lines and that their occurrence in certain localities is as 
certain as the spring itself. I conclude, therefore, that, in every instance where a truly 
maritime species is found in the interior, the seeds were brought there by birds.
