of Winter , and that they pafsin certain beaten fraffs well known to the Indians, as well as 
the Englifh ref ding there , who lie in wait for them., and kill great Numbers for their. 
Skins, Yhey 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 Search¬ 
es after Birds difcoverd fome few that are found in England at certain Seafons, to be found 
alfo in Bengal. andfame found in Europe, thd not in England, are found alfo in Ben¬ 
gal : Whether they continue there all the Tear, or are only Birds of Pajfage, as they are 
with us, I cannot tell j but it would be worth the Obfervation of any curious Englilhmaa 
rejiding in that Country ; therefore IJhall fet down their Names , viz. 
fhe Greater Redftart, 
fhe Witwal, 
fhe Wheat-Ear, 
fhe Small-Green-Wren, 
fhe Houfe-Swallow, 
Yhe Bee-eater, 
fhe Wry-neck, 
Merula Saxatilis, Aldrov. 
Idlerus, Plinii , 
Oenanthe or Vitiflora* 
Regulus non criftatus, 
Hirundo domeilica, 
Merops, 
lynx or Torquilla. 
Of this Number the Wheat-Ear, the Green-Wren, the Houfe-Swallow and Wry¬ 
neck, are found in England in Summer, and all of them in the Southern Parts of Eu¬ 
rope, where I believe they are Birds of Pajfage alfo. All thefe I have met with in Par¬ 
cels of Birds fent from Bengal; and if any Perfon of good Obfervation in India could dif- 
cover that thefe Birds are abfent there while prefent with us, andprefent there whilf abfent 
here , it would anfwer the 9 Jueftion, whither and in what manner do thefe Birds pafs ? 
It is indeed my Opinion , that all thofe Birds which arefeen with us only fome part of the 
Year , pafs into other Countries when they are out of our fight. We are certain fome of 
them mufi , becaufe they do not breed while they continue with us; thefe are the Wood¬ 
cock, Snipes, Field-fare, Redwing and fosne others : Yhefe I believe, go into northern 
Countries to breed. Yhe Summer Birds of Pajfage alfo come from snore fout hern Countries 
northward to us, and breed here: Seeing then Birds retire from more northern Parts to 
winter with us, why jhould not tender Birds who vifts us in Summer and breed here, retire 
and Jhelter themfelves in fouthern Countries , where they are fecure from cold, which they 
cannot
