442 NOTES ON THE 



The eggs, from three to four in number, are a light-blue, 

 with a faint shade of green, one of which is occasionally 

 thinly spotted with rusty-brown. I do not know of their hav- 

 ing more than one brood in a season. They become quite 

 common again during September, by the general migration 

 southward, individuals not infrequently being seen as late as 

 the first of November in open autumns. 



Note. When conversing with Professor S. F. Peckham, 

 formerly on the faculty of the Minnesota State University, and 

 of late connected with the Smithsonian Institution, he spoke of 

 the nest of this species having come under his notice once in 

 Rhode Island, in open ground, and subsequently gave me a 

 written statement as follows: "The nest was on the ground 

 without protection, in a piece of old chestnut woods without 

 underbrush. Eggs, four in number, about two-thirds the size 

 of the Robin's, somewhat thicker in shape, and of a darker 

 green color." 



I had the pleasure of learning from him that he had given 

 the birds of New England much study in the years gone by, 

 and was therefore speaking by the book. It was certainly a 

 very remarkable freak for the Hermit Thrush to build in such 

 a place. But most rules have their remarkable exceptions, 

 for they are of finite formulation while the Infinite fills all the 

 spans in the great viaduct of materialized truth.

Who that has watched the departure of the Robin from au- 

 tumn to autumn through successive years, and felt the relent- 

 less touch of artic frosts follow them so soon with their drift-
