In the summer of 1910, Dr. George F. Kay, while engaged in a study of the Bering River Coal Field of southeastern Alaska, discovered some subspherical, concretion-like bodies in the ''shales of the Tokun formation.'' Three specimens were brought back by Professor Kay and these through his kindness have been submitted to the writer for study. The largest is a smooth oval body with long and short diameters of 8.6 and 7.6 centimeters; the smallest is likewise smooth, irregularly oval, and with diameters of 4.3 and 3.8 centimeters. All three are dark-colored, compact, close-grained stone, brittle under the hammer, and fairly heavy.
