76 NEW YORK STATE MUSEUM 



At Swartoutville, a little hamlet about half way between Brincker- 

 hoff and Hopewell Junction, on the farm of Irving Hitchcock, a 

 calcareous conglomerate, with the pebbles squeezed into bands, out- 

 crops in places between the bluish-gray limestone, referred to above 

 as possibly representing the Beekmantown, and the calcareous shales 

 with interbedded limestone layers, the latter lying on the west along 

 the margin of the limestone. In other places the shales with their 

 interbedded limestones grade downward into a fine conglomerate 

 with what looked like S. compacta and other fossils. 



During the spring of 1909 a number of new cuts were made in 

 the limestones along the road from Johnsville to Stormville in the 

 process of constructing the State road. In one of these, about two 

 miles east of Johnsville, a fairly distinct impression was found. 

 This may be a fossil. The general form is apparently preserved, 

 but the details are obliterated. Other blackened and much more 

 distorted impressions were noted. These impressions, together with 

 other markings, such as bunches of calcite crystals, mark the rock 

 as probably fossiliferous. 



Some peculiar lithic variations within the Fishkill limestone. 

 Northeast of Johnsville, on the farms of Messrs Gildersleeve and 

 Taylor, are frequent outcrops of a coarse silicious limestone, which 

 was not noted elsewhere in this limestone belt. It somewhat 

 resembles the basal quartzite at times. It is always calcareous, 

 effervescing readily with cold dilute acid, but leaving a prominent 

 residue of quartz. It is interbedded with other limestones, which in 

 their lithological characters recall the chamois-colored beds in the 

 Beekmantown of the Wappinger creek belt. The silicious rock 

 just referred to outcrops along the road south of Bonney hill north 

 of Taylor's house, while Bonney hill seems to be largely made up of 

 the medium-bedded chamois-colored rock, except at the west along 

 the lower portion of the scarp slope, where it gives place to a gray 

 limestone. No fossils were discovered in these limestones. It is 

 noteworthy that they lie close to the northward continuation of the 

 strike of the rocks in the West Fishkill Hook district. 



A diligent search was made within this limestone east of the 

 western margin for a conglomeratic layer, but none was found. 

 What appear to be coarse brecciated zones are of frequent occur- 

 rence, particularly west of the Honness spur. These were noted 

 just southeast of Milton C. Hustis's house at Brinckerhoff, between 

 Mount Honness and Fishkill creek, where the rock is mashed, and 

 in the Newburgh, Dutchess & Connecticut Railroad cuts between 

 Fishkill Village and Brinckerhoff, and less noticeably but plainly
