LAKE SUPERIOR. 



pools of the shore. But the deep, cold waters of the lake, permitting 

 no growth of water-plants, except occasionally in a sheltered cove, 

 possess no attractions further. Accordingly, the only water-birds we 

 saw were Larus argentatus, Colymbus glacialis and Mergus cucul- 

 latus, all which we usually saw in small numbers every day, and 

 one specimen of Colymbus septentrionalis. In the neighborhood of 

 Detroit we saw black terns in abundance, and heard that some 

 of the light-colored species bred about St. Joseph's Island, but we 

 saw none of them beyond the St. Glair. 



Seeing the importance that is beginning to be given to even 

 minute details of geographical distribution, I have subdivided the fol- 

 lowing list of species observed, so as to present first the species of most 

 extensive range, and afterwards those of more confined localities.
