the U. S. Survey has been very distinctly advantageous. In retrospect one can, however, easily see how these benefits might have been materially increased by more frequent conferences and consequently more thorough mutual understandings and adjustments.
Paleontology and Natural History.—With the small amount appropriated for the survey it would have been injudicious to use any of it on paleontology, but Mr. T. H. Aldrich contributed, without cost to the state, Bulletin No. 1, published in 1886, containing descriptions of new Tertiary fossils, with nine plates of illustrations. This is the first installment of what is designated to be a complete and illustrated account of our Tertiary paleontology.
So also Professor Herrick, of Denison University, contributed a List of the Fresh Water and Marine Crustacea of Alabama, with Descriptions of New Species, which was published by the Survey in 1887, as Bulletin No. 1 of Vol. V. This paper, which also appeared as a Memoir of the Denison Scientific Association, is illustrated by eight plates of figures of the species described.
From the beginning of the survey collections have been made by myself of the native plants of the state, and these collections, combined with those of Dr. Charles Mohr, of Mobile, were by him arranged and mounted, and the joint herbarium deposited in the cabinet of the University of Alabama. A preliminary list of the Alabama flora was printed in 1880, and Dr. Mohr is now engaged in preparing for the survey a report on the Botany of the state, in which every known indigenous phænogamous plant and fern will be listed, and full accounts given of the timber, forage, useful and noxious plants. The geographical distribution of the Alabama flora and the mapping of the botanical provinces of the state will be a valuable feature of this report, which is now far advanced towards completion.
In the progress of the work a new species of Croton of shrubby habit, C. Alabamensis, has been discovered, and many rare plants have been found growing upon our soil.
Geological Map.—Lastly, the preparation of the geological map of the state has engrossed a large part of the time and
