This paper is a short historical review of studies for investigating crustal deformations car ried out in Kyoto University during the period from 1909 to 1965. Main topics are (i) Obser vations of Earth tides with tiltmeters and the “Shida number”, (ii) A plan to detect free oscillations of the Earth proposed by Dr. Shida and observations of tidal strains with extensometers, and (iii) Crustal deformations associated with earthquakes. Among others, the Shida's pro posal in 1922 to observe the free oscillations of the Earth should be evaluated more.
