two; and I have several times observed individuals to appear in a grove 
of young oaks, build a nest, remain a few days, and then disappear, 
perhaps to return again in a week and build other nests. 
“The fox-squirrel loves to take up his abode in a hollow tree which 
stands out alone at a little distance from the surrounding timber, as if 
desirous of having a clear view of all going on around him. When he 
once becomes domiciled in a tree, he does not leave it, unless disturbed, 
pairs being observed to inhabit the same tree for five or six successive 
years. It is less prolific than either the migratory or Carolina squirrel. 
From two to four young are usually brought forth at a birth, the most 
common being three; but in one instance I have seen five. Two 
litters are probably produced each season. So far as has been observed, 
they are always brought forth in the hole, the nest of leaves being used 
only as summer-houses. Like the young of most rodents, they are 
ugly, unsymmetrical little beings, at first, with monstrous heads and 
closed eyes; and it is some time before they acquire the elegant propor- 
tions and agile movements of their parents. 
“These squirrels sometimes leave their holes for food and even for 
amusement, in very cold and rainy weather, when they are found mov- 
ing about much more than the migratory species. But, though active 
at this time and apparently engaged in play, they do not now ‘bark’ 
as on warm and pleasant days.” (l. c., pp. 56-59, 61.) 
Regarding the Fox Squirrel’s habit of burying nuts in the ground, 
Mr. E. T. Seton writes, “‘On the first of August, 1903, I watched 
for an hour the Fox-squirrels of City Park, Madison, Wis. A large 
male that seemed master of those near came forward as I offered him 
some peanuts. The first three he ate, the rest he buried. His pro- 
cedure was the same each time; seizing the nut in his teeth, then in 
his paws, he turned it two or three times in his mouth and appeared to 
be licking it.’’ (Life Histories of Northern Animals, I, 1909, p. 325.)
