GEOLOGY OF THE MERRIMACK DISTRICT. 54I 



the stream, but the rock appears near E. N. Patch's. Irregularities in 

 direction are to be expected in Lyndeborough, since the trend of the 

 rock at Patch's if continued, would carry the ledge a mile below its next 

 outcrop, west of J. F. Holt's. It continues south of west, and makes 

 the hill near the glass works at South Lyndeborough, The range runs 

 S. 55° W., near the village, and dips 50° S. 35° E. The first railroad cut 

 west of the station barely touches this bed of quartz dipping 75° S. 40° E. 

 By the eye this range can be followed over the large hill east of Burton 

 pond, on the town line between Lyndeborough and Wilton. I am not 

 certain of the occurrence of this rock in the north-west corner of Wilton, 

 but it may be seen just in the edge of Temple, between A. H. Fry's and 

 J. Kendall's. On the other side of Kendall's is one of the finest develop- 

 ments known anywhere along the range. It is from four hundred to five 

 hundred feet wide. The strike is about N. 30° E. It may be traced 

 continuously from Kendall's to near Temple village. The dip is probably 

 north-westerly. The rocks adjacent dip in that direction, and the only 

 observation I have of the position near Temple is that it is doubtful. 

 About two miles west of Temple village is a small quartz outcrop, west 

 of N. Holt's, dipping N. 50° W. into a hill. There is a valley running 

 west from this point, or rather a notch between Temple and Kidder 

 mountains leading to Sharon. I have searched diligently all through 

 this gorge, the mountains upon both sides, and the whole of the adjacent 

 townships of Sharon and New Ipswich, and am unable to find any 

 further traces of the Hooksett band of quartzite. Whether it is con- 

 cealed by the material composing Temple or Barrett mountain, seeing 

 that it overlies the gneiss formation, whether some enormous disloca- 

 tion has put it far to one side, whether the formation has pinched out, 

 or whether some other theory may be devised to explain its absence, is 

 at present unknown. 



The Manchester Range of Quarts. The first well-developed outcrop 

 of this range, at its north-east extremity, is in the south-west corner of 

 Allenstown, at J. Hall's. We find a high hill, at the comers of Hooksett, 

 Allenstown, and Candia, the existence of which may be due to its being 

 composed of this refractory material. The ledge is clearly traceable from 

 T. J. Gate's to J. Clark's, or nearly to Moody pond, with the dip north-west. 

 The surface at Gate's has been beautifully smoothed and polished by the
