Kingfisher will sometimes lay its eggs on the bare earth, at the 
end of a hole, without making any nest. In Suffolk the nests of 
this bird have been found in holes in gravel-pits, at the distance 
of a mile from any large pond or river. The eggs are white and 
round,

At the time when Swallows are congregated in the autumn 
for the purpose of migrating, a part of them have been observed 
to ascend in the air in a spiral direction beyond the reach of 
human vision, and after continuing out of sight a short time, to 
descend again. Sometimes they would continue to do this at 
intervals for two or three days together, and then all would dis-

whether there is an upper current of air favourable to their mi-

to have a greater scope of vision ?. 
A young Swallow, which was kept alive by a lady, was observed 
to become uneasy as the time of migrating approached; and when 
its cage was hung in the air, the wild Swallows came about it, 
and appeared to invite it to go with them. After they had all 
disappeared it became tolerably easy. 
The following extraordinary circumstance in the natural his- 
tory of the Swallow, which occurred at Christ Church, Ipswich

deners could have taken up hundreds of these birds in their 
hands: they were collected in knots, and sat on the grass in 
parcels of thirty and forty. This, there is reason to believe, was
