A Cactus-Slab Fan

The fibrous portion of this fan represents the fiber of a cactus leaf from which the pulp has been removed. In the young slab, these fibers are tender and fragile, but they become tense and rigid in the old slabs. An excellent paper may be made from this fiber, and it will doubtless in time be put to many other economic uses.
