THE JAY.

stances. The young cuckoo cannot, by any means, 
support its own weight during the first day of its 
existence. Of course, then, it is utterly incapable 
of clambering, rump foremost, up the steep side of 
a hedge sparrow's nest with the additional weight 
of a young hedge sparrow on its back. Add to this, 
that an old bird, the young of which are born blind, 
always remains on the nest during the whole of the 
day on which the chick is excluded from the shell, 
in order to protect it. Now, the old hedge sparrow, 
in the case just mentioned, must have been forced 
from her nest by the accidental presence of an in- 
truder. Her absence, then, at this important crisis, 
was quite contrary to her usual economy, for she 
ought to have been upon the nest. It follows, then, 
that instinct could not have directed the newlj' 
hatched tind blind cuckoo to oust the hedge sparrow, 
even though it had strength to do so, because the 
old bird would have been sitting close on the nest, 
but for the circumstance which forced her from it, 
namely, the accidental presence of an intruder. 
The account carries its own condemnation, no 
matter by whom related or by whom received. I 
had much rather believe the story of baby Hercules 
throttling two snakes in his cradle.

When naturalists affixed the epithet glandarius 
to the name of the jay, they ought also to have ac-^ 
corded it to the jackdaw, the rook, the carrion crow, 
and the magpie, not forgetting the pheasant and the
