and dodecahedral habit, with minor development of the trapezohedron 
n{211). Small druses in some of the specimens contain thin blades of 
aragonite. 
The garnet occurs at the contact between aplite and serpentinized 
peridotite. Plate III illustrates the mode of occurrence of one of these 
aplitic intrusions at the Hall pit; in other places they have a more 
regular dyke-like form. 
Figure 14. Grossularite, rose-coloured crystal from the Union pit; has the 
form of the rare six-faced octahedron «(853), with minor development of the 
dodecahedron and the four-faced cube g(320). 
Old i Standard Adine. Small reddish-brown crystals of garnet occur 
here, associated with tourmaline, in a pegmatite dyke. 
American Chrome Pit. The crystals obtained from this pit are rich 
in forms, and are of especial interest in that they exhibit faces of the cube, 
a form very rarely found on crystals of garnet. In general the habit 
is dodecahedral, modified by the forms n(211) and r(332) which are about 
equally developed; the remaining forms, s(321), e(210), and g(320)
