Ai)])roxiin;itoly ;U() foot above tho stoiio (jiiairy and south of the 

 higliway up tho hill in northwesteni Broome, ju^it over the town- 

 ship line, is a small excavation showing blue sandstone (D^) which 

 splits into rather thin layers. No fossils "svere found in the bed 

 rock; though therc^ an^ ])lonty in loose ])iecos of stone on tho sur- 

 face which, however, probably came with the drift. On the high- 

 way just after it turns south in the northwestern corner of Broome 

 and 145 feet above D^ are green shales and thin sandstones (D^) 

 which are in the Sherburne formation. On the highway 30 feet 

 higher near the turn to Franklinton are red and green mottled 

 shales and sandstones (D^). Another prominent terrace of gray- 

 ish, slightly reddish and greenish shaly sandstone (D^^) ap])eare 

 65 feet higher. Below this terrace along the highway are shales 

 which are mainly red. At the to}) of the ridge is grayish and 

 greenish gray, coarse grained, thin l>odded sandstone (I>^-). In 

 the field plenty of loose red sandstone is found. The siiminit of 

 the hill in the eastern part of Fulton township is only about 35 

 feet higher and this summit according to the barometric section 

 is 1500 feet above tho Schoharie river at ]\Iiddloburg. 



The rocks from D^ to the to]) of ^lohegantor hill have in general 

 the lithologic characters of the Oneonta formation to which they 

 would ordinarily be referred. The reds and greenish gray rocks 

 on this liill, however, appear stratigra])hically much lower than 

 the Ixise of the Oneonta sandstone in the Sux(iuohanna valley or 

 even in the western ])art of Schoharie county, so that they have 

 nearly, if not completely, rei)lacod tho rocks of tho Ithaca form- 

 ation. This fact will be shown still more, clearly by the section 

 of the Avost<M'n side of the IMohogantiu- hill in tho oastoru ])art of 

 Fulton townshij). This section southeast of Middloburg and up 

 the eastern side of ^[oheganter hill is shown in the following
