The Tally limestone was also analyzed, and found to contain a large amount of phos- phates. In conclusion, we are quite satisfied with the results which have been obtained by these examinations ; and as they lead to practical results, and explain some facts which were at first obscure, we think the labor and time bestowed upon them will not be lost or useless. In the vicinity of Christian-hollow, and indeed through a wide region of country, there are many marl ponds, some of which are situated in a manner similar to the small green lakes of which something has been said already. In connexion with the foregoing analyses, I deem it proper to give the composition of the marl which has been obtained from one of these ponds in the town of Preble. The annexed cut, fig. 38, will convey an idea of the mode in which they are distributed over the country. ANALYSIS.

A north and south section, running in the range of five or six marl ponds or small lakes, and extending between five and seven miles, or from the south end of Christian-hollow, to a point near Cortlandville. The lakes are above the Green lakes of Manlius, being mostly in a position superior to the Tully limestone. The slopes 1, 2, 3, consist of a succession of terraces, which form the oflset into Christian-hollow. 44*. Please note that these images are extr
