In concluding this list of references I would suggest to the student the desirability of securing the following catalogues or lists of publications. A glance at the lists in this volume will show that a surprisingly large number of the papers or works are governmental publications, many of which have long been out of print, but many may still be secured from the different departments or from the Superintendent of Documents at Washington, D.C.
1. U. S. Geological Survey. List of Publications, including maps. Washington, D.C.
2. Superintendent of Documents. Lists of publications of the U. S. Department of Agriculture. Washington, D.C.
3. Smithsonian Institution. List of publications. Washington, D.C.
4. U. S. National Museum. List of publications. Washington, D.C.
