our resident Birds, and have passed on to their moreNorthern 
haunts: an opinion which will also account for the fact, that 
a few will sometimes make their appearance long after all 
onr resident Birds seem to havo left us ; and I have myself 
witnessed the arrival in a state of exhaustion and fatigue, 
from the broad expanse of the Ocean, and late in the Au- 
tumn, of small flocks of Martins, that seem to have had their 
passage interrupted by boisterous opposing winds. The 
latest date given for the disappearance of these Birds, refers 
to the year 1835, and belongs to a considerable flock of our 
own Birds ; which sometimes disappeared for a few days 
and then appeared again, still continuing a recognition of 
their former residence. Towards the end of their stay, the 
weather being cold, they passed the night in holes of a wall 
originally formed for scaffolding.
