232 \Y. S. BAYLEY — SYENITES FROM NEW ENGLAND. 



syenites and the desire to ]>ut on record the discovery of another locality 

 for them within the United States. 



Thanks are due to Messrs II. K. Morrell of Gardiner and R. G. Clough 

 of Monmouth, Maine, for valuable aid in the collection of specimens of 

 the Maine rock, and to Mr. M. M. Smith of Deland, Florida, and Mr. 

 W. If. Mason of Moultonboro for information respecting the New Hamp- 

 shire locality and for abundant material from it. Mr. J. S. Diller and 

 Dr. F. W. Clarke of the United States Geological Survey have also done 

 all in their power to help make the descriptions as complete as possi- 

 ble under the circumstances, the former gentleman having furnished 

 thin sections of both the Maine and the New Hampshire rocks, and the 

 latter having kindly provided analyses of both, f desire to express my 

 appreciation of their aid, and also to thank Mr. G. P. Merrill of the 

 National Museum for a chip from FfaAves' original specimen of the New 

 Hampshire rock, and Messrs L. G. Eakins, W. H. Melville and W. F. 

 Hillebrand for the careful chemical work that appears in the body of 

 this article. 



The Eleolite-Syenite of Litchfield and otiifi; Localities in Maine. 



Distribution. — ft is not quite certain that this rock has been found in 

 place. Nearly all the specimens that have been sent abroad to the 

 museums of this and other countries have come from bowlders or loose 

 fragments lying on both sides of the road running from South Litchfield 

 post-office, in the town of Litchfield, Kennebec county, Maine, to the 

 city of Gardiner, on the Maine Central railway, about six miles south of 

 Augusta. The distance of the locality from South Litchfield is about 

 three-quarters of a mile, and from ( rardiner about eight miles. Here the 

 fragments and bowlders are often quite large. Some are half buried in 

 the soil on the gradual slope of a hill, while others lie on the surface. 

 From the great abundance of the bowlders and their large size, together 

 with their thick accumulation in such a small area, it is argued by many 

 competent geologists that the parent ledge is somewhere in the near vicin- 

 ity. However this may be, there can be no doubt that the rock is a schistose 

 eruptive. In large pieces the schistosity is quite apparent, and even in 

 hand specimens it may sometimes he readily detected. The character- 

 istic mineral of this occurrence is cancrinite. The other two localities in 

 which cancrinite predominates over sodalite and eleolite are southeast 

 of South Litchfield, on the farms of Messrs Sawyer and Spaulding (see 

 map, figure 1). In both of these cases the rock is in the shape of bowl- 

 ders. At Sawyer's several large ones lie on the surface south of the road 

 and within sight of it ; at Spaulding's broken fragments are found built 

 into stone walls. The underlying rock at both places is quite different
