A tube is described which is fabricated from parts readily available to most departments of physics. With the proper auxiliary equipment, it is possible to determine the ratio of charge to mass of the electron to 0.2–0.3% in a reasonable time. It is of additional interest that from the data giving the magnetic field of the solenoid, a value for the earth's magnetic field may be obtained.
