the battlements and roof, yet many hang or cling 

 for some time by their claws against the surface of 

 the walls, in a manner not practised by them at any 

 other time of their remaining with us. 



The swallows seem to delight more in holding 

 their assemblies on trees. 



November 3, 1789. Two swallows were seen 

 this morning at Newton vicarage-house hovering 

 and settling on the roofs and out-buildings. None 

 have been observed at Selborne since October 11. 

 It is very remarkable, that after the hirundines have 

 disappeared for some weeks, a few are occasionally 

 seen again : sometimes in the first week in Novem- 

 ber, and that only for one day. Do they not with- 

 draw and slumber in some hiding place during the 

 interval ? for we cannot suppose they had migrated 

 to warmer climes, and so returned again for one day. 

 Is it not more probable that they are awakened from 

 sleep, and like the bats are come forth to collect a 

 little food? Bats appear at all seasons through the 

 autumn and spring months, when the thermometer is 

 at 50°, because then phalcence and moths are stirring. 



These swallows looked like young ones.] — Ob-

Some few pairs haunt the new and open streets 

 of London, next the fields, but do not enter, like the 



wings to the sun, and then flying off" all together, but soon returning to 

 their former situation. The greatest part of these birds seemed to be 

 young ones. — Markwick.
