Chaetura pelagioa . 
At the opposite end of this boat-house iny boat-house 
built in I89S , well up in the north gable inside, I found a 
Swift's nest attached to the vertical wall of rough spruce board¬ 
ing. Fresh droppings beneath indicated that it is occupied this 
season, as it was last, according to Jim, but I saw nothing of the 
birds. Their only chance of ingress and egress, apparently, is a 
small opening just over the big sliding doors in front
