"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."
