The discovery of the minor planets or asteroids has become so general in recent years that the work of following them after their discovery is of great importance. After an orbit has been calculated the asteroid can be identified and a permanent number and name given to it; then it is a known member of our Solar System. The asteroid whose orbit and ephemeris have been computed and are given in this abstract, was discovered by Joel H. Metcalf at Taunton, Mass.
