"Camphor is found in many trees and shrubs," continued her governess, "but in all others except the camphor tree of Sumatra and Borneo it has to be distilled from the wood and roots. The camphor-laurel, which is about the size of an English oak, is the most important of these trees. It grows abundantly in the Chinese island of Formosa, and 'camphor mandarin' is the title of a rich Chinaman who pays the government for the privilege of extracting all the camphor, which he sends to other countries at a large profit. Every part of this tree is full of camphor, and the tree gives out, when bruised, a strong perfume.
