The simple, cells already described, when single or agglutinated and produced on the surfaces of the leaves, stems, and seeds of plants as hairs, form a fibrous material also valuable, to which the name Sur- face Fiber has been given. Such hairs are found enveloping the seeds of plants, and when they are produced in the bolls or capsules of spe- cies of Gossypium form the cotton of commerce. The fiber bundles, therefore, whether
