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 



youna 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.
