SUPPLEMENT TO MINEEAL LEXIOON. 755 



1892 Anthophyllite. Chesterfielil. 



E. S. Daua. Sys. Min. Localities, p. 1058. 



I have never foiiud this mineral in Chesterfield, nor any of the minerals with 

 which it is associated; nor do I recall any other citation of the mineral from 

 this town. I snppose it to be the brown cumuiingtonite from the bluffs west of 

 Burnell's pond. 



1858. Anthophyllite. Enfield. 



Specimens labeled "anthoiihyllite gneiss" in the State collection. 

 E. Hitchcock, iSros.9G,97, under gneiss. Cat. State Col. Mass. Agr. Kept., p. 15. 

 A dark-brown, bladed mineral. The powdered fragments all extinguish lon- 

 gitudinally, as if it were a rhombic mineral. 



1895. Anthracite. Holyoke. 



In Chicopee shale of Triassic age below the Holyoke dam. In thick masses 

 coating siderite. It has rounded surfaces, showing that it was introduced into 

 the fissure as a bitumen. It is in very brittle layers, which give a yellow flame 

 for an instant and then glow without further flame. (See p. 370.) 



1895. Apatite. Blandford. 



Occurs in the Osborn soapstone quarry, in rich, deep oil-greeu crystals an 

 inch long, intercrystallized with chlorite. (See p. 85.) 



1895. Apatite. Chester. 



Crystals 1 to 3""™ in length occur on and in the diaspore. (See p. 143.) 



1895. Aragonite. Chester. 



A beautiful fibrous satin spar occurs in the serpentine at the old mine, in 

 sheets a foot square and l.J inches thick. (See p. 143.) 



1895. Barite. Holyoke. 



Cavities 4 inches long and one-third inch wide and an inch deep, with rec- 

 tangular ends or ends beveled like barite crystals, occur in the Chicopee shale 

 below the Holyoke dam. (See p. 370.) 



1892. Bastite. Westfield. 



E. S. Dana. Sys. Min. Localities, p. 1060. Cited as Schiller Spar (Diallage). 

 This is a bastite derived from enstatite, from Munns Brook. 



1818. Beryl. Emerald. Chestei-field, Goshen, Northampton. 



Chesterfield furnishes them in great abundance, from the weight of an ounce, 

 or less, to six pounds. Hexagonal prisms; diameter sometimes twelve inches; 

 light green (Waterhouse). iSTorthampton and Goshen (Hunt). All coarse 

 granitic beryl.
