BUILDING AND ORNAMENTAL STONES. 423 



These rocks Lave been qiuuTied for many years and very extensively 

 used for all manner of constrnetive purposes. The following list in- 

 cludes some of the more important buildings and monuments made 

 wliolly or in part from this material : Charter Oak Insurance Building, 

 Hartford, Coini. ; soldiers' monument, at Manchester, N. H.; monu- 

 ment to the discoverer of anesthetics; the Germania Savings Bank; 

 Equitable Life Insurance; Masonic Temple; Massachusetts State 

 ])risoii, and some seventy-live other buildings in Boston, and Booth's 

 Theater in New York. 



According to Professor Jlitclicock, the more important quarries are 

 situated on what is known ns Itattlesnake Hill, an elevation yome fJOO 

 feet above tlie level of the Merrimac Kiver, and which consists almost 

 entirely of granite rocks. Other gi-auites of this class occur and are 

 (juarried at Allentown, Suniii)ee, and Peterborough, and are used for 

 simihir purposes, tliough they are not widely known outside of New 

 England. Gray biotite granites of good quality are quarried at Mason, 

 Fitzwilliam, Kumney, Hanover, Portsmouth, and other towns, as 

 noticed in the tables. 



The Peterborougli, JNlason, and Fitzwilliam are exported to some ex- 

 tent to the neighboring States, but the others mentioned are used in 

 the near vicinity. 



The New nam])sliire granites are nearly without exception of tine 

 and even grain and well adapted for all kiiuls of work. The Concord 

 rock is practically identical both in general ai)pearance aud mineral 

 compof^ition with that of Hallowell, Maine, already described. 



New York. — This State, although rich in marbles, limestones, and 

 sandstones, produces little of general interest in the way of granite 

 rock. A coarse, gray biotite gneiss is quarried at Hastings- upon- Hud- 

 son, in Westchester County; a somewhat darker hornblendic gneiss at 

 Cold Spring, in Putnam County; and a coarse red hornblendic granite 

 at Clayton, in Jefferson County. 



The gneisses are quarried chiefly for the rough work of foundations 

 in the vicinity. Tiie red granite from Grindstone Island (Clayton post- 

 ollice) is a beautiful stone and takes a tine polish. The sample for- 

 warded to the National Museum, however, contains jtarticles of iron 

 pyrite, which unQt it for monumental work. The ])resent product of 

 the ipiarry is made into paving blocks and monuments, principally for 

 Chicago, 111., and Montreal, Canada, though two beautiful columns of 

 it are to be seen in the new capitol building at Albany, N. Y. 



New Jerseij. — Aside from a single quarry of greenish-gray gneiss at 

 Dover, Morris County, in this State, no granitic or gneissic rocks are 

 anywhere regularly worked within the State limits. But "Gneissic 

 rocks are found in a few localities in tliick beds and so Jointed that large 

 Hud regular blocks can be quarried out at a comparatively snuxll cost.
