The new mineral kernite, Na2B4O7.4H2O, was received through Hoyt S. Gale of Los Angeles, California, and is reported to occur in quantity in the southeast corner of Kern County, California, in the Kramer boron district. The name kernite is proposed after the county name. The exact locality is about 4 miles north of Rich, a station on the Santa Fe R. R. and about 25 miles directly east of Mojave, being in Sec. 22, T. 11 N., R. 8W. The mineral was discovered in exploratory borings at a depth of several hundred feet. Ulexite and possibly colemanite are associated minerals. The geology of this field has been described by Gale1 and Noble.2
