TIIK EAST GREEX^VICU-EITFIELD SYXCIilKE. 



A narrow syncline comes out from beneath the sands east of Green- 

 wich village and near the east line of Greenwich. Traces of it appear to 

 the nortli, mostly covered by sand, along the roadside east of Warner's pond. 

 It makes the high hill which extends down the east line of Greenwich and 

 Enfield, and is well exposed along the road i-unning east from ICnfield. 

 Here, near W. X. Avery's, the fibrolite-schist is a nearly pure bucholzite, 

 in thick layers, in a fine-gi-ained feldspathic quartzite witliout brown mica, 

 graphite, or garnet. As it lies immediately above the araphibolite it occu- 

 pies the position of the whetstone-schist. The center of the series is occupied 

 by the i-usty mica-schist, while on the west there is a dull-greenish graphite- 

 gamet-muscovite-schist and a granulite with its garnets bordered by green, 

 and Ijoth these beds indicate the presence of the basal beds below the 

 amphibolite, but not in thickness sufficient to be put upon the map. In 

 Ware this ten-ane is well exposed between the town farm and the schoolhouse 

 to the west. 



It is shifted to the west by the great fault in the soutli of Ware, and 

 across Palmer it forms the high Pattaquattic Hill and the range of high 

 ground soutli across the town. On the south flank of this hill, northwest 

 of J. Carrigan's, the black mica-schists are locally so crowded with the 

 large rounded "augen" of feldspar that the separated folia of the schi.st, 

 2-5"™ thick, v>'ind in and out among the latter and occupy not more than a 

 fourth of the space in a cross-section of the rock. 



In Palmer it can best be .studied along the road running east from the 

 Center, and its first branch to the northward, especially in tlie hill ea.st 

 of B. Olney's. Here a distinct band of quartzite appears above the amphib- 

 olite. It iims out soon after reaching Mon.son.

ARGUMENT FOR THE IDENTITY OF THE SCHIST SERIES EAST OF THE 

 CONNECTICUT WITH THOSE ON THE WEST. 



In the nrtrth of the State the beds in the first band east of the river 

 agree most closely with the con-esponding beds west of the river, and some 

 of them, as the Conway schists, agree exactly in a multitude of characters. 

 Southward the sti-ata change greatly, but in the latitude of Amherst the
