340 A. Wing's Discoveries in Vermont Geology. 



In the Sudbury valley, \\ miles south of the? village, on the 

 land of Mr. Clark Morton, the Trenton trilobite, Trinuckus 

 us, was first found in May, 1866, in the blocks of a 

 stone wall which the owner said had been quarried near by ; 

 and, Mr. Wing says : " I walked home that night— seven 

 miles— after sundown, glorying in. my discovery of a Trenton 

 fossil in Sir William Logan's Quebec'Group. I was, however, 

 dampened in all this on reading, after reaching home, in Pro- 

 fessor Hitchcock's Report, that the Trinixcleus had been pre- 

 viously found in a bowlder in Sudbury ; for I could not tell 

 whether mine came from a bowlder or not."* But "afterward, 

 in May, 1867, I discovered the Trenton trilobite near the same 

 spot, and in great abundance." It was associated with various 

 other Trenton fossils, twenty or more species of which were 

 later collected by Mr. Billings. 



The limestone, like that of West Rutland, and the slates 

 adjoining, all dip eastward. The limestone accordingly, sav* 

 Mr. Wing, constitutes an anticlinal between two synclinals of 

 slate — those of the slate belts or ridges. 



Mr. Wing also states that he afterward found the Trirwdem 

 us ten miles southeast of Sudbury (half way to West 

 Rutland) in Hubbardton, in a limestone band sixtv vards wide 

 in the heart of the "great central belt of slates;"" and also 

 farther south, one or two miles north of the slatc-M 

 West Castleton. 



4. Eastern Orwell and Shoreham, Whiting and Cornwall 

 The towns directly north of Sudburv are Whiting and Corn- 

 wall, and those adjoining these on the" west, Orwell and Shore- 

 ham. The area of Eolian limestone — that of its west branch 

 —covers only the eastern half of Orwell and Shoreham, the 



Cornwall, so that the western part of each of these towns is
