THE BRITISH OR LIGHT-TAILED SQUIRREL 715 
to a climber balanced at some considerable altitude in a 
precarious position. 
Occasionally Squirrel’s nests are reported from curious 
situations, as when the Rev. J. G. Tuck found one in a loophole 
of the church tower of Tostock, Suffolk. Its foundation was 
an old sparrow’s nest, to which a quantity of dry grass had 
been added. A second remarkable nest, of which Mr Forrest 
sent Barrett-Hamilton an account, was placed in a straggling 
gorse bush at a height of not more than 4 feet from the ground. 
Sometimes an old magpie’s nest may be put into repair by the 
Squirrel, which probably has to renovate its drey every season, 
although the dreys are built of a strength sufficient to last for 
years. An impossible situation sometimes ascribed is a 
woodpecker’s hole in a tree trunk, but clearly such a hole 
would be too small to admit the body of a Squirrel. 
Mr W. Evans says: ‘Clean and trim as it appears to be, 
the Squirrel, like the Hedgehog and the Mole, is greatly 
infested by a flea, the species in this instance being Cevato- 
phyllus sciurorum, Bouché, which is invariably present, and 
usually in abundance, both in the nests and on the animals 
themselves.” * 
Every Squirrel is supposed to possess two or three dreys, 
and one of these is no doubt strengthened and repaired for 
the reception of the young. According to Edward Jesse,’ the 
prospective mother begins by gathering mouthfuls of dry 
benty grass, of which she makes a considerable deposit. Just 
before the young are born, she scratches or pulls the fur off 
her stomach, and thus makes them a warm lining. 
The number of young varies from one to six,® and the 
average of twenty litters, recorded in Barrett- Hamilton’s notes, 
from many parts of the British Islands is three. Two litters 
each summer would appear to be quite usual in the south 
{though not in Scotland), but the young are most often found 
in the nests in March and April. Earlier instances are, how-

near Droitwich on 31st August 1918 ; above the drey three young, belonging to an 
earlier litter, were clinging to the tree trunk.
