It may be mentioned in this connection that this plant was 

 found in St. Joseph Co., Ind., near Lydick, in a tamarack 

 swamp. Only one speciman was found but this was certainly 

 not a cultivation. The plant is No. 10568 of the U. N. D. Herbarium. 

 It is an immature though healthy one. This reference was over- 

 looked in the "Notes" and is the most easterly locality for the 

 plant we have been able to record for the region.

BY BROTHER ALPHONSUS, C. S. C. 



After May 20, certain species, although common summer 

 residents, were seldom seen. The explanation of their scarcity 

 would seem to be that these species are found only in peculiar 

 localities during summer, and the few that were seen after May 

 20, were straggling migrants. This would not cover of the case 

 of the Killdeer, Cedarbird and Yellow-throated Vireo. The rarity 

 of the Killdeer was doubtless due to the early nesting of this species. 

 The Cedarbird is a wanderer, and so may frequently be absent 

 from a given locality. The scarcity of the Yellow-throated Vireo — 

 only three records of the species having been made during the 

 summer — is inexplicable to the WTiter. 



The absence, after May 20, of the Purple Finch, Dickcissel, 

 Rose-breasted Grosbeak, Maryland Yellowthroat and Cardinal 

 may be accounted for variously. The Purple Finch and Dickcissel 

 were not recorded once during spring or summer. The Rose- 

 breasted Grosbeak was not found on any day in summer. The
