Fifteen or twenty feet_ofa pale greenish clay or earth.No marl grains are found in this layer, though it is called marland possesses active properties as a manure. _, It is flaky in ,.its structure, and when exposed to the air fad_s to a light ashcolor.3. From five tofifteen fester the above day_ largelymix_dWith marl grains.• The last named layer is opened to the greatest thicknessin the pits of Jacob White_ Peter Drummond and Amos White,in Deal ; in that of O. F. Fettit, Shark River, and in that" ofJ. S. Furman, near Lower Squankum, it is not so thick. Inall these it can be seen running into the layer next below.There arc no localities where all these'layers can be seen ina single plat% but they can be seen in succession in nu_nbersof places, as in the pits of Elisha West_ G. Hendrieksen andThOmas Burden_ of Deal ; in those of J. Shafto_ H. Hurley_G. Shafm, and J-. L. Tilton, of Shark' River_ and in those ofT. Longstrcct_ T. Weeks_ and J. S: Forman, of Squankum.Fossils are not very abundant in this bed.. A few*casts,and still more rarely shells, have been found in the lowerlayer ; it is not known that any have been found in the middlelayer ; in the upper, casts and impressions of shells arc found.They have not been examined with sufficient careto determinethe species ; they are, however_ entirely different from those ofthe two lower beds.The accompanying sections across the marl stratum, show_thcpositions of the several beds. The scale of distances is twomiles to one inch. The scale of heights about 400 feet t_)aninch= the heights_ however, have not been accurately measured.These sections arc taken at .right angles to the stratum."_Inaddition to showing the positions of the several beds,they also exhibit the effects of peculiar configurations of sur.t'aoe on the extent of.the marl bed exposed : thcs though the,same beds are shown in each of the three section_ the amountof marl at the surfaceappears to be quite different in the samebed as seen in the different:sectional views.The first bed ap-NEW JERSEY GEOLOGICAL SURVEY
