GLACIAL DRIFT. 273 



Miscellaneous Items. 



A few other facts concerning the dispersion of drift and other glacial 

 phenomena are worthy of preservation, although it is not possible to 

 state them systematically. I have placed several hundred specimens 

 of boulders found in various parts of the state in the Hanover museum, 

 properly catalogued, so that it may be consulted by those who wish to 

 verify the statements of this report, or obtain hints of facts not alluded 

 to in it. Many of the specimens represented strange information at 

 the time of the collection, not now valuable except as illustrating the 

 fact of dispersion. Others are from noted boulders, or collected upon 

 the tops of mountains, or represent the supposed underlying rock in 

 the absence of ledges. 



On the west slope of Gardner's mountain, near Hunt's, are boulders of the Craftsbury 

 concretionary granite (petrified butternuts), with ordinary granite and hornblende rock 

 from Vermont. 



In West Littleton are two houses (Wheeler), and others in Lancaster, built of the 

 Vermont granite brought to New Hampshire by glaciers. 



j\It. Carmel in Pittsburg, as seen from Dixville mountain and Mt. Washington, pre- 

 sents a good example of a large eminence rounded on the north-west by the ice striking 

 it, and rough on the lee side where the force of the ice had abated. 



Between North Lisbon and Streeter pond a mass of till more than 100 feet thick has 

 been cut through by the south branch of the Ammonoosuc, and fine sections are ex- 

 posed upon it. Ledges are scarce near the river. 



Rocks full of segregated veins weather unequally, often affording curious shapes. It 

 is quite common to see these stones placed in conspicuous positions upon walls or in 

 dooryards by the farmers, who take pride in their exhibition. The siliceous limestone 

 of the mica schist, the finer-grained sienites, and the segregated veined variety of 

 (Lake) gneiss afford the best examples of this erosion. I recall examples in Bath 

 and Center Harbor, resembling piano-stools and mushrooms. 



The importance of soapstone has led to noting the position of boulders of it in cer- 

 tain parts of the state. Those in Pelham, Keene, and at Island pond in Hampstead, 

 have not been referred to their source. The original bed is yet to be discovered. In 

 New Boston, by the school-house west of S. Dodge's, are several large boulders, dis- 

 tant about four miles in the direction S. 20° E. from the bed on Mt. Misery, Weare, 

 their probable source. The same occur in Weare, at the south foot of Mt. Misery. 



Serpentine boulders are common but not abundant in Keene. One in Walpole 

 weighs about 350 pounds. 



The numerous gneissic boulders in West Epping led to the discovery of a small area 

 of this formation in the Lamprey river.
