598 STRATIGRAPHICAL GEOLOGY. 



Lond pond, in Meredith, with course N. 30° E.; trap, west of S. and S. 

 Fogg's, Ossipee ; near Wolfeborough village and other places. 



The quartz bands of the Manchester gneiss occur here, also, though 

 they have not been traced out so carefully. As they extend but a 

 short distance, they cannot be expected to be so well developed. It is 

 possible that two of the ranges seen in the Lake district are the natural 

 continuation of those in Hillsborough county after their emergence from 

 the mica schist blanket, and beyond the eruptive mass of Moose moun- 

 tain. An examination of the map will show that the Hooksett and Man- 

 chester bands might correspond to these in Strafford brought up with 

 the gneissic island, then, submerged again, turning to run more northerly, 

 and reappearing in Wakefield and Effingham. In Wakefield the eastern 

 range is one hundred feet wide at L. C. Perry's, midway between 

 Wakefield and East Wakefield stations. There are also signs of the 

 quartz at B. Drew's. At the Peavey place (N. H. Cook's) limestone 

 just like that in Amherst, with similar associated minerals, — epidote 

 and molybdenite, — overlies the quartz, dipping to the north-west, ex- 

 posed in a ledge twelve feet wide. Inasmuch as the related rocks here 

 agree in mineral contents and position, we have reason for believing this 

 is the Manchester band of quartz prolonged into the Lake district. It 

 may be the same with that on the town line close by Province pond. To 

 the south there is a similar band, to be mentioned under Montalban, on 

 the north side of Lovewell's pond, which occupies very nearly the place 

 of this range, but is a superior formation. The Hooksett range appears 

 on Porcupine ledge, near North Wakefield, in the east corner of Wolfe- 

 borough. The quartz is more than a hundred feet wide, lying somewhat 

 to the rear of the precipice. It may be traced for several hundred feet 

 in length, and dips north-westerly; so that both ranges are inclined in 

 the same direction. It is said there is a ledge of quartz at C. Hodgdon's 

 in Ossipee. I have not been there, but it is exactly on the line from the 

 Porcupine ledge to Pocket hill in the east part of the town. At O. San- 

 ders's it runs up hill, being vertical, in the direction N. 50° E., and it is 

 fifty or sixty feet wide. It has been explored by miners in search of the 

 precious metals. There are indications of the continuance of this range 

 at B. H. Emerson's and J. Leavitt's, 2d, in Effingham. The boulders are 

 almost large enough to be called ledges. These two bands have been
