appear only as narrow truncating faces; the cube faces also are quite 
small. Figure 15 shows the average habit of these crystals. It should 
be mentioned that although many of the crystals were examined under 
the binocular microscope, only five or six were completely measured, 
and it is possible that additional forms would be found if a special investi- 
gation were made; this remark applies also to the other garnet occurrences 
described here. 
Figure 15. Grossularite, pale amber (succinite) coloured crystal from the 
American chrome pit; rich in forms, and especially interesting in that it 
exhibits faces of the cube, a form rarely found on garnet crystals. 
These garnets are grossularite of pale amber (succinite) colour, and 
usually they are about 2 mm. in diameter; they are associated with white 
massive calcite in a compact, granular, olive-green diopside rock. 
Montreal Chrome Pit. Andradite is the only variety of garnet noted 
at this locality. Most frequently it is associated with pale green clino- 
chlore of rather pronounced prismatic habit, and platy masses of white to 
pale lilac-coloured diopside; the order of crystallization is diopside, garnet,
