A squirrel often displays oddities both in the place selected for
storing the cones and the manner of their arrangement. Usually the
cones are wisely hoarded both for curing and for preservation, by
being stored a few in a place. This may be beneath a living tree or in
an open space, placed one layer deep in the loose forest litter
scarcely below the general level of the surface. They are also stowed
both in and upon old logs and stumps. Sometimes they are placed in
little nests with a half-dozen or so cones each; often there are a
dozen of these in a square yard. This scattering of the sap-filled
cones, together with the bringing of each into contact with dry
foreign substances, secures ventilation and assists the sappy cones to
dry and cure; if closely piled, many of these moist cones would be
lost through mould and decay.
The numbers of cones hoarded for winter by each squirrel varies with
different winters and also with individuals. I have many times counted
upwards of two hundred per squirrel. During years of scanty cone-crop
the squirrels claim the entire crop. The outcry raised against the
squirrel for preventing far extension, by consuming all the seeds, is
I think in the same class as the cry against the woodpecker; it
appears a cry raised by those who see only the harm without the
accompanying good. The fact is that many of the cones are never eaten;
more are stored than are wanted; some are forgotten, while others are
left by the death of the squirrel. Thus many are stored and left
uneaten in places where they are likely to germinate and produce
trees. John Muir too believes that the Douglas and Frémont squirrels
are beneficial to forest-extension.
Commonly the cones are stored in the same place year after year. In
dining, also, the squirrel uses a log, limb, or stump year after year.
Thus bushels of the slowly decaying scales and cobs accumulate in one
place. It is not uncommon for these accumulations to cover a square
rod to the depth of two feet.
I know of a few instances in which squirrels stowed cones in the edge
of a brook beneath the water. One of these places being near my cabin,
I kept track of it until the cones were used, which was in the spring.
In early autumn the cones were frozen in, and there they remained,
unvisited I think, until the break-up of the ice in April. Then a
squirrel appeared, to drag them from their cold storage. He carried
each by to his regular dining-place. Clasping the cone vertically,
base up, in his fore paws, he snipped off the scales and ate the seeds
beneath in regular order, turning the cone as he proceeded as though
it were an ear of corn and he were eating the kernels.
I have often waited to see a squirrel go for something to eat after a
snowstorm. This he did in a matter-of-fact way. Without hunting or
hesitation he went hopping across the snow to a spot immediately above
his supplies, where he at once pawed his way down into the snow and
came up with a cone.
