The following excellent account of the construction and of the measurement of vibration of the Sather tower is a letter very kindly addressed to me under the date of Dec. 5th, 1918 by Professor C. Derleth, Jr., of the Civil Engineering Department of the University of California, and has been reproduced here on account of its great importance in connection with the problem of the vibration of high steel structures. As the period of vibration of the tower complete is 1.14 sec. we have here a case of ""short column,"" whose natural period is not much longer than that of the destructive earthquake motion, and whose base is exposed to the maximum fracturing seismic force.
