trated by stating that during a visit to the locality in the summer of 

 1883 the writer was shown the remains of a huge block of granite 

 three hundred feet long, twenty feet wide, and from six to ten feet 

 thick, that had been blown out from the quarry in a single piece and 

 afterward broken up. The largest single block ever quarried and 

 dressed was the General Wool Monument now in Troy, New York, 

 which measured, when completed, sixty feet in height by five and a half 

 feet square at the base, or only nine feet shorter than the Egyptian 

 Obelisk now in Central Park, New York. The stone is light gray, 

 often slightly pinkish in color, and corresponds closely with that from 

 the now abandoned quarries on Dix Island, whence were taken 

 the granite monoliths, thirty-one feet in height, for the Treasury 

 Building at Washington. Second only to the quarries at Vinalhaven 

 are those at Gloucester, Massachusetts the quarries of the Cape Ann 

 Granite Company. This rock is coarser in texture than that of Vinal- 

 haven, and often of a slight greenish color. The new Masonic Tem- 

 ple at Philadelphia, and the Butler House, on Capitol Hill, Washing- 

 ton, are good illustrations of the adaptability of this stone for gen- 

 eral building purjwses. 



Closely resembling the Cape Ann granite is that quarried at Quincy 

 in the same State. Quarries were first regularly opened here in 1803, 

 though it was from bowlders of this rock that was built in 1749-'54 

 King's Chapel, still standing on the corner of School and Tremont 

 Streets, Boston. Quincy granite also was used in the construction of 

 the Bunker Hill Monument, and it was for the transportation of this 

 stone from the quarries to Charlestown that was built the first railway 

 in America. The color of the stone is deep blue gray, and its fitness 

 for interior decorative work is well shown in the granite stairways 

 and polished pilasters of the new City Buildings in Philadelphia. 



For columns, house-trimmings, and especially monumental work, 

 the granite from Hallowell, Maine, is used most extensively. This 

 rock is of fine and even grain, and very light gray, almost white in 

 color. Its texture is such that it can be carved very readily, and it 

 has been used in statuary work more than any other of our granites. 

 The statues on the Pilgrim Monument, at Plymouth, Massachusetts, 

 are of this stone. An Italian designer, who served his apprenticeship 

 in Roman studios, is employed by this company, and many of the 

 workmen at the quarries are said to be Italians who worked in marble 

 in Italy, but have learned to cut granite since their arrival at Hal- 

 lowell. 



A granite, closely resembling that of Hallowell, is quarried very 

 extensively near Concord, New Hampshire, and is used for similar pur- 

 poses. Stones similar to these, but not at present in the market, are 

 found near Frederickton, Virginia, and Atlanta, Georgia. 



The red and pink granites now in the market are nearly all from 

 Calais and Jonesboro, in the eastern part of Maine, though others are
