I30 NOTES OF A NATURALIST. 



strange exception that on the rocks nearest the houses 

 there were several small birds, which appeared to be 

 rather shy, and which I was not able to approach. I 

 was afterwards told that these birds live on the grain 

 which they are able to steal or to pick out from the

 had sought the refreshment of green food, and had 

 vainly gnawed away the painted surface.

 turned to the shore, where broken shells and other 

 remains of marine animals presented at least some 

 variety. Seaweeds appeared to be scarce, but some 

 were to be seen in the little pools left among the 

 rocks by the retreating tide. 



just as I was about to collect some objects which 

 might have been of interest, the steam-whistle of the
