at the foot of an alder bush. I could not make sure what it 

 was, at first thinking it to be a Yellowthroat, but on seeing 

 the nest and eggs I thought it was the Nashville. Both birds 

 kept flitting near the nest, but kept well hid in the dense growth 

 but I soon got a glimpse of the female. I was not quite sure 

 what it was and called Prof. Knight. 



We silently watched the birds, occasionally getting a quick 

 glance at the female. When we both saw the male with the 

 heavier cap markings, we excitedly exclaimed: Wilson's 

 Black-cap! Tieing my handkerchief to a bush near the nest

 think the most of my readers can picture it all in their minds. 

 At last the critical moment came and we had perhaps, snapped 

 the camera for the first time, on a female Wilson's Black-cap 

 on the nest. We herewith give you the two exposures made 

 by Prof. Knight. 



The nest was made up outside of fine dead grasses (neatly 

 woven, yet a frail structure) lined with fine grasses and a very 

 few horse hairs. It measures: Outside diameter 3.50 inches 

 inside diameter 1.50. Outside depth 2.25, inside depth 1.25 

 inches. 



The eggs were five in number with a dull white ground 

 finely dotted over the entire surface with cinnamon, rufous and
