Considerable activity in corundum mining has sprung up within the last few years, and several new occurrences of corundum in quan tity have been brought to light, those of special note being in Ontario Canada, where the corundum occurs in a syenite, and in North Caro lina and Georgia, where it occurs in a gneiss or a quartz-schist.
