Conglomerates into Gneiss, Talcose Schists, Fe. 373

cat the whole subject of metamorphism becomes com- 
paratively easy and full of interest. This affords no small relief 
to one, who, like myself, has been for years perplexed and con- 
founded in studying the — — rocks of the Green

We have i oe, feiens poe where the pebbles of conglomerates 
have been elongated and flattened so as at length to be converted into 
the silicious laminee of the schists and gneiss and the cement into mica, 
tale, and feldspar. 
In a Report on the Geology of Massachusetts made by me in the Lad 
1833 a singular conglomerate was described near Newport R. I. :— 
nodu 
posed of elo gated rounded of qu into - 
slate, with a cement of Talcose slate, the nodules ge fro sateen 4 
of a pigeon’s egg, to four and oes six feet in their longest 
another, lying in a north agi atk direction. The cong omerate is di- 
vided fissures running east and west vertical to the horizon, and 
pee as ma give the rock a quite peculiar « 
e facts were repeated in me pre Reports upon 
iacceninee 4 in 1885 and 1841. But it was not until we found 
an analagous conglomerate along nearly the whole western side 
of the Green mountains that the special bearing of Mok — 
mentioned upon metamorphism occurred to us. 
then (1859) visited Newport to get a clearer view of the ser a 
the hope that they wroath help us better to unravel the intrica- 
cies of the Vermont ee rhs Mae t same year I read be- 
fore the Amer. Assoc. for Adv. of Se a aper on the subject, 
as it was developed at Newport and 4 E. Hey San where an 
interesting locality had been discovered ans another
