the western face of the Grand Moraine, when signs of nesting activity induced 

 me to stop. A female Leuco was making feverish trips to a spot midway of the 

 very roughest boulder field, a hundred yards away. By dint of rushing from cover 

 to cover during her periodic absences, I succeeded in approaching within thirty 

 feet and marked her precise entrance. This bird obtained her nesting materials, 

 chiefly weathered grasses of last year's vintage, from a rocky exposure at least a 

 hundred yards away. Her hubby, meanwhile, had his hands quite full chasing 

 off a dastardly rival who insisted upon urging his rejected and pointedly un- 

 welcome claims. ft jjjjSi 

 Returning upon the 11th of July equipped with collecting toolsYand 

 camera, I find the lady away and five fresh eggs awaiting her attention — and 

 mine. I rigged up the camera, and the owner of the eggs returned presently; 

 but she was not greatly exercised by my presence, and she insisted upon playing

 I could barely discern the front of the nest from the outside, but after carefully 

 tamping in cotton over the eggs, I removed the nest entire, with contents, being 

 compelled, en route, to turn it upon its side in order to clear the narrow passage 

 Even this squeezed the nest somewhat; but the pearly beauties, five of them, 

 blushing pinkly, arrived intact. 



Set 116/4-22, taken July 14th: — A peculiar interest attaches to this nest 

 from the fact that, in all probability, it is the product of the same pair of birds 

 which we robbed in the same well three years before. Giles and I had located 

 it on the 5th of July, when it stood ready for eggs. The previous nest, referred 

 to in the preceding article, was the one of nearly all moss construction whose eggs
