Excerpt from A Study of the Fauna of the Hamilton Formation of the Cayuga Lake Section in Central New York The identification of species is probably always affected more or less by personal judgment. In order to make the statistics of the greatest relative value, therefore, no attempt was made to criticise these personal elements in the author; and while it is probable that another worker dealing with the same specimens would not. Reach absolutely identical listing of species, it is probable that the errors, if any, from inaccuracy of specific identification are so small relatively as to not disturb the statistical value of the facts recorded. Further and more exhaustive search, also, may be expected to considerably modify the statistics here given; but even this fact does not detract from the value of those here recorded. The more. Refined the analyses become the more perfect will be our knowledge of faunal composi tions. The present investigation is a step in the direction of attain ing the fullest possible perfection in recording faunal statistics, and in making these faunal analyses as perfect as they can be made, toward which end the contributions of many workers will be needed. With such statistics in hand we may hope to understand better the laws of evolution as affected by and related to the varying conditions of environment and time. It will be noticed that the thickness of the Hamilton, as measured by Prosser in the Ithaca well, is feet - t hat is, between the top of the Onondaga (corniferous) limestone and the base of the Tt lime stone. The exact thickness was not determined by the author. The reason for this is that the great thickness and similarity in the charac ter of the rock of Zones B and (1 made the accurate measurement of these zones impossible. This is shown in the section (fig. 2) by broken lines. Nevertheless it is believed that the discrepancy does not affect the accuracy of the succession of the fossiliferous zones recorded in this paper. Attention is here called to the fact in order to show how difficult it is to make exact correlation for short dis tances when the sediments are. Of similar composition and structure and the general fauna is the same. For the purpose of ascertain ing the exact thickness of each zone, a continuous section is neces sary, but a long series of shorter sections, where the dip is slight, offers the advantage of a greater number of exposures of the rocks for the collection of the fossils. It is hoped that the present sample of what can be done in the way of an historical study of a fossil fauna may inspire other workers to make similar studies of the rocks in their own localities for comparison and demonstration of the geographical as well as the geological modifications of fossil faunas.

"Six miles north of the city of Ithaca, high on the west side of Cayuga Lake, the longest of New York's fabled Finger Lakes, is Cayuga Nature Center. Originally built in 1939 as a country refuge for children exposed to tuberculosis, the CNC is today a popular activities center and respected authority on the natural resources of the Region. This volume summarizes the varied flora, fauna, and other natural wonders of the land preserved at the CNC, much of which applies to northern and central New York State." -- cover.
