Cole, Escl, is found auo.thor deposit, covering an area of fl_y acres. The peat rest.ing upon the mar!, is from four to six feet in thickness ; andthe marl from six to eight feet, resting upon a becl of sand andgravel. On the f_m of.Mr. Isaiah Vaonctten, one mile anda half northeast.of Hainsville , is another:deposit covering anarea of twenty acres, and overlaid by a. deposit of peat fromthree to eight'feet in thickness._ On ,the farm of Mr_BenjaminP. Van Syekle, in Sandiston Township, three miles northwestof Tuttlc's.Corner, and two miles southeast of Diogman'sFcrry_ is found a.dcpesit of calcareous sinter, covering an areaof at least five acres. :It is exposed on either side of a smallstream to the depth,of several feet. A well fifteen feet deephas been dug into it without passing through its whole extent.Though very hard: and compact upon the surface, it becomessofter and more pulverulent as it descends In it are foundnumerous nodules, or concretionary masses, w])ich have beenformed by the deposition of the lime around a twig or someother substance as • nucleus for the aggregation of calcareousparticles. _.'ho source of this deposit may. be traced to aepri'ng, ]_alfa mile distant, near the house of Mr. James Struble.This spring issues from the base ofdimestoee ridge, and empties• into a small reservoir or pond,-whence it passes to Mr. VanSyckle's land. In the bottom of this reservoir grows the Churn,a genus of aquatic plants. While growing atthe bottom ofponds and streams , it has a dark green color, but upon beingremoved and exposed directly to the atmosphcre_ it soon becomeswhite and crumbles to a fine powder con/posed chiefly0f.the carbonate of lime. Large quantities of it are constantlyforming at the bottom of this poad_ and it requires to be removed,from time to tim% in order to prevent the pond frombeing filled by, its rapi d accumulation.Another extensive deposit of calcareous sinter is found onthe limestone slope at Dingman's Ferry, a little above the4NEW JERSEY GEOLOGICAL SURVEY
