The sand§ which form a strip along <strong>the</strong> sou<strong>the</strong>rn border<strong>of</strong> this. county join <strong>the</strong> marls in a very irregular line,ridges <strong>of</strong> <strong>the</strong>m extending up almost to <strong>the</strong> middle <strong>of</strong> <strong>the</strong>county, while in <strong>the</strong> valleys <strong>of</strong> <strong>the</strong> streams, <strong>the</strong> marl comes to<strong>the</strong> surface several miles fur<strong>the</strong>r south. They have not yetbeen examined with sufficient care to render it necessary tomake any report upon <strong>the</strong>m.The interest felt in <strong>the</strong> marl stratum by a very large portion<strong>of</strong> <strong>the</strong> inhabitants <strong>of</strong> Monmouth, has induced me to devotemost <strong>of</strong> <strong>the</strong> time, thus far, to ascertaining and systematizingfacts relating to it. The examinations <strong>of</strong> <strong>the</strong> clay stratum and<strong>of</strong> <strong>the</strong> sands promise to be <strong>of</strong> much practical utility, though <strong>the</strong>soils where <strong>the</strong>y occur have not yet been brought to <strong>the</strong> highstate <strong>of</strong> cultivation <strong>of</strong> <strong>the</strong> marl region, and <strong>the</strong>y are generallythought <strong>of</strong> less value.The regular order <strong>of</strong> occurrence <strong>of</strong> <strong>the</strong> different beds <strong>of</strong>marl in <strong>the</strong> district surveyed led to a desire to examine <strong>the</strong>irrelative position in <strong>the</strong> southwestern part <strong>of</strong> <strong>the</strong> State. Forthis purpose <strong>the</strong> stratum was crossed from Allentown to NewEgypt_ and ag_finin <strong>the</strong> vicinity <strong>of</strong> Salem, and <strong>the</strong> same order<strong>of</strong> succession <strong>of</strong> beds was found.The marl pits <strong>of</strong> N. Woodward, at Cream Ridge, belongto<strong>the</strong> flint bed: The ridge itself is part <strong>of</strong> <strong>the</strong> ferruginous sandbed, The pits at Hornerstown, and those <strong>of</strong> Mr. Imlay andMr. Horner, near New Egypt, are in <strong>the</strong> second bed; so also"are <strong>the</strong> gray marls, such _s those in Governor Fort's pit.The pits <strong>of</strong> Mr. Irons, south <strong>of</strong> New Egypt, and o<strong>the</strong>rs from<strong>the</strong>re on to Poke Hill, in Burlington County, belong to <strong>the</strong>lowest layer <strong>of</strong> <strong>the</strong> third bed_ The upper layers have not beenfound in that vicinity.The marls in Salem Co{mty, "at Mannington Hill and atWoodstown, belong to <strong>the</strong> second bed.
