was approached. I am not certain as to just where in the fifty- 

 feet layer No. 945 was taken, although I think from near the 

 middle. 



" No. 944 comes from a series of old abandoned hydromica slate 

 quarries on the east side of the ridge extending for half a mile or 

 more south from the railroad cut. The quarries have exposed the 

 limestone in considerable quantities, yet at no place could I find 

 the whole thickness of the layer as it is in the cut at the railroad. 



"The stone varies considerably in character, some of it resem- 

 bling that exposed .in the cut, and again in places thin layers of 

 highly crystalline, almost pure white, limestone occur. No. 944 

 comes from one of these layers about three inches thick. Just to 

 the north of the railroad there is a larger blufi: of this limestone 

 and the outcrop can be traced a mile or more to the north. 



" No. 946 was taken from a line of boulders in the town of 

 Lebanon. These may have been carried there from the outcrop 

 near Willimantic, possibly from Bolton, yet the direction of the 

 line would indicate that they came from neither of these localities, 

 but from some place not yet discovered, between these, and to 

 the north of where the boulders are found. 



" No. 947 is from a very extensive bed about three miles to the 

 northwest of the city of Norwich. This doubtless is the most 

 extensive exposure of limestone in Eastern Connecticut, as the 

 outcrop extends two and a half or three miles along the brow of a 

 hill, and at an old " Gold Mine" a layer fifty feet thick is exposed. 

 The rock is deceptive in appearance, looking much like gneiss and 

 has a great deal of feldspar, intermingled also in large veins. 



"Professor Forrest Shepherd showed me where some lime, burned 

 in an indifferent way from this outcrop, and spread in a careless 

 manner upon a grass field near the city had caused a yield of 

 from four to six times as much grass as grew where the lime had 

 not been placed. 



" This limestone has easy transportation down hill to the rail- 

 road. 



" The purest limestone of eastern Connecticut that occurs in 

 abundance is found in very extensive beds on the line between 

 Preston and North Stonington. The accompanying analysis by 

 Prof. J. H. Washburn, of the Storrs Agricultural School, exhibits 

 the chemical composition of a sample. (See Table of Analyses.) 

 This limestone has a bluish tint, is said to cut like Itahan marble, 

 and is admired for its strength and durability. It is densely crys-
