"To think," exclaimed Clara, "of camphor growing in that way! But how do
they get it out, Miss Harson? Do they cut great holes in the trunk of
the tree?"
"No, dear; I have just read to you that the camphor cannot be seen until
the bark is split open, and the grand trees have to be cut down. But to
do this is no easy matter. The hard, close-grained timber requires days
of hewing and sawing to get it severed. The masses of roots are as
unyielding as iron, and run twisting through the soil to the distance
of sixty yards. Even at their farthest extremity they are as thick as a
man's thigh."
"I shouldn't think the camphor was worth all that trouble," said
Malcolm; "it don't seem to amount to much, any wary."
"It is more valuable than you suppose," replied Miss Harson; "for,
besides preserving furs and woolen fabrics from the devouring moth, it
protects the contents of cabinets and museums from the attacks of the
minute creatures that prey upon the dried specimens of the naturalist.
Not any of the insect tribe can endure the powerful scent of the
camphor, and they either retreat before it or are killed by it. But its
principal value is in medicine. It is used both internally and
externally. It acts as a nervous stimulant, and is a favorite domestic
remedy.--So you see, Malcolm, that camphor really amounts to a great
deal, and we could not very well do without it."
"How can people tell when there is any camphor inside the tree?" asked
Clara.
