m Beajls of Paffage, but 1 have been informed by a Perfon of Reputa- 
tion^ who now refdes in one of the Englifli Forts in Hudfons-Bay, that 
the Deer in that Country pafs northward in the beginning of Summer., 
and return to the South at the approach of Winter, and that they pafs 
in certain beaten TraSis well known to the Indians, as well as the Englifh 
ref ding there, who lie in wait for them, and kill great PJ umbers for 
their Skins. "They are faid by the Natives to pafs very far North in 
the Summer, and to return in the Winter far enough Southward to 
come to a temperate Climate. I have in my Searches after Birds dif- 
coverd fame few that are found in England at certain Seafons, to be found 
alfo z';2 Bengal; and fame found in Europe, thd not m England, are found 
alfo in Bengal : Whether they continue there all the Year, or are only 
Birds of Paffage, as they are with us, I cansiot tell ; but it would be 
worth the Obfervation of any curious Englifliman ref ding in that Coun- 
■^ry ; therefore I fjoll fet down their Names, viz. 
Yhe Greater Redftart, 
‘The Witwal, 
The Wheat-Ear, 
The Small-Green-Wren, 
The Houfe-Swallovv, 
The Bee-eater, 
The Wry-neck, 
Merula Saxatilis, Aldrov. 
Iderus, Plinii, 
Oenanthe or Vitiflora, 
Regulus non criftatus, 
Hirundo domeftica, 
Merops, 
lynx or Torquilla. 
Of this Number the Wheat-Ear, the Green Wren, the Houfe-Svvallow 
and Wry-neck, are found in England in Summer, and all of them in 
the Southern Parts of Europe, where I believe they are Birds of P affage 
alfo. All thefe I have met with in Parcels of Birds fent from Bengal ; 
and if a?iy Perfon of good Obfervatiott in India could dif cover that thefe- 
Birds are abfent there while prefent with us, and prefent there whilfl 
abfent here, it would anfwer the i^uefion, whither and in what manner 
do thefe Birds pafs ? 
It is indeed ?ny Opinion, that all thofe Birds which are feen with us 
only fome part of the Year, pafs into other Countries when they are out of 
our fght. We are certain fame of them muf, becaufe they do not breed 
while they continue-with us-, thefe are the Wood-cock, Snipes, Field-fare, 
Redwing atid fottte others ; Thefe I believe, go into northern Countries
