It is the same way in the family of Rusty the Fox Squirrel. Some
members are rusty red, some are a mixture of red and gray, and some
are as gray as Happy Jack himself. Way down in the Sunny South Fox
Squirrels always have white noses and ears. In the North they never
have white noses and ears. Rusty the Fox Squirrel is just a little
bigger than Happy Jack and has just such a handsome tail. He is
the strongest and heaviest of the Tree Squirrels and not nearly
as quick and graceful as Happy Jack. Sometimes Rusty has two
nests in the same tree, one in a hollow in a tree for bad weather
and the other made of sticks and leaves outside in the branches
for use in good weather. Rusty's habits are very much the same
as those of Happy Jack the Gray Squirrel, and therefore he likes
the same kind of surroundings. Like his cousin, Happy Jack,
Rusty is a great help to me."

Seeing how surprised everybody looked, Mother Nature explained.
"Both Happy Jack and Rusty bury a great many more nuts than they
ever need," said she, "and those they do not dig up sprout in the
spring and grow. In that way they plant ever so many trees without
knowing it. Just remember that, Chatterer, the next time you are
tempted to quarrel with your cousin, Happy Jack. Very likely Happy
Jack's great-great-ever-so-great grandfather planted the very tree
you get your fattest and best hickory nuts from.

"Way out in the mountains of the Far West you have a cousin called
the Douglas Squirrel, who is really a true Red Squirrel and whose
habits are very much like your own. Some folks call him the Pine
Squirrel. By the way, Chatterer, Happy Jack forgot to say that
you are a good swimmer. Perhaps he didn't know it."
