is yellowish, /)wing to a small portion of common sand. The 

 shells are in a very broken condition, but we may recognise 

 them to belong to the well known secondary fossils of the marl. 

 The large shell called Terebraiula Harlani seems to constitute a 

 large portion of the mass. Something similar is seen farther to 

 the south, on the farm of Mr. Field, about one and a half miles 

 from Eatontown. This deposit deserves to be traced more mi- 

 nutely, as it is probably a new variety of marl fit for the agricul- 

 ture of the neighbourhood, containing much more lime than the 

 greensand formation usually possesses. 



Long Branch. — Along the cliffs facing the ocean in front of the 

 boarding-houses at Long Branch, appearances in several places 

 show that the true marl stratum meets the sea-coast in this 

 quarter, and that it cannot lie at any considerable depth below 

 the beach. About half a mile north of Renshaw's, at apparently 

 the highest point in the cliff, the astringent clay bed which so ge- 

 nerally accompanies the marl as an overlying stratum is exposed, 

 rising four or five feet above the average level of the beach. This 

 itself is strongly indicative of the existence of the marl at no great 

 distance beneath. The probability of this is manifested, how- 

 ever, in another way. The sand of tJie beach contains a very 

 notable proportion, often jive per cent, or more, of the green 

 granules of the marl, which examination assures me cannot be 

 derived from any of the strata in this part of the bank, and which 

 therefore, can only come from a bed extending into the sea below 

 the ocean level, or at least lying as low as the base of the cliff. 

 This mixture of the green granules among the sand of the beach 

 is observable along the whole of the bay shore, from near Chapel 

 to the Telegraph Hill, and thence along the ocean side from the 

 mouth of the Shrewsbury river past Long Branch to Deal, and 

 somewhat further. It has been discovered somewhat recently, 

 that the beach sand throughout this line is endowed with active 

 fertilizing powers, attributed heretofore to salt and other supposed 

 marine substances in the beach. But the well known properties 

 of the green grains, coupled with the fact that in every place 

 along the shore further south than Deal, where the marl does not 

 reach the coast, the sand of the beach contains none of the dark 

 granules, prove conclusively that the benefits so distinctly per- 

 ceived, are attributable to the source which I suppose. The good
