entered it together when the whole structure gave way and 
came tumbling down to the ground, breaking up into frag¬ 
ments as it struck against the branches during its descent. 
How the Squirrels managed to escape falling with it is 
a mystery, but just as it started one ran out and after 
it had got well under way I saw the other hanging by 
one foreoaw only but tha.t seemed to be quite enough for 
he almost immediately recovered himself and got back on 
the upper side of the branch. They both took the loss of 
their home very coolly although literally not a single 
fragment of it remained in place. Some few of the twigs 
had lodged lower down and these the Squirrels visited 
and inspected in turn, but they showed no disposition to 
replace any of them.
