3. Columbite at Northfield, Mass. 
This mineral was sent to me last autumn for cba dirwrer: by 
Mr. M. A. Brown, of Springfield, Mass., an enterprising mine-

which here forms veins from ten to fifteen feet in width, travers 
ing the micaceous schist. Beryl is also somewhat abundant in 
uniform shortness or tabular form, and the regularity of their 
terminations by a single plane. In this respect they resemble 
the beryls of Goshen and Norwich. e columbite is tolerably 
crystallized, black and shining, with a specific gravity of 6°, 
which, it will be observed, is much higher than that of the Con-

Very interesting specimens of zepalatiined fibrilite in distinct 
white prisms having nearly the form of kyanite are occasionally 
met with in the drift of this region. The crystals penetrate a 
compact micaceous rock in all ris and from their great 
hardness are found projecting at various angles quite beyond 
the surface, notwithstanding the iuitign to which the masses 
have been subjected.
