90 BULLETIN OF THE 



track of the last locality known as the "Woods Schoolhouse." The 

 schoolhouse of the name has disappeared, for its foundations only remain ; 

 but the explorer can readily find his way to the spot by passing from the 

 new schoolhouse on the Cedar Tree Neck road westwardly along the ser- 

 pent kame, the only deposit of this nature on the island, until he passes 

 a stone wall, a little to the west of which, in the roadway and on the 

 bare ground thereabout, he may find an abundance of fragments of this 

 peculiar sandstone. Circumstances prevented my undertaking any care- 

 ful study of this place until seventeen years after its discovery. In 1887 

 I returned to the locality, and with the help of my assistant, Mr. Foerste, 

 undertook a careful collection of the abundant fragments which I found 

 at this point, as well as a systematic study of all the area of the island 

 which gave promise of affording similar material. The search for other 

 localities was fruitless, and as this is the only one on the island which 

 has afforded fossils in condition for identification, I shall hereafter limit 

 my account of the bed to what is exhibited at this point. 



As is shown in the accompanying section, the Cretaceous fragments 

 found at this locality occur only within a small area. They have been 

 found over a surface having an east and west extension of about 300 

 feet, and a north and south length of about 200 feet. The position is 

 immediately to the south of a shoved moraine, which extends up to and 

 probably includes this part of the drift accumulations. In this area, 

 from the surface to the depth of four or five feet, or as far as the exca- 

 vation penetrated, by far the larger part of the fragments are composed 

 of the deposit in question. The rock consists of a very coarse sandstone 

 abounding in quartz pebbles, containing indeed little other material save 

 quartz fragments from an inch in size downward. The largest of the 

 fragments containing fossils are about three feet across and a foot thick ; 

 the greater part of them are extremely angular, showing by their form 

 that they have been transported for a very short distance. Moreover 

 the extreme softness of the material would make it impossible for it to 

 endure any distant ice carriage. The sand in which the fragments con- 

 taining fossils were embedded appears to be to a great extent derived 

 from the destruction of the same rock. This fact is indicated not only 

 in the physical aspect of the sands, but in the character of the vegeta- 

 tion which grows upon them. Generally, in this morainal district, the 

 decomposition of the pebbles containing large amounts of feldspar and 

 mica affords a moderately fertile soil, which maintains grass. In the area 

 where these fragments abound, the sand is evidently far more siliceous 

 than elsewhere in the area of the moraine, and is too lean to support
