A series of field research works was carried out to get information of snow accumulation, physical properties of snow cover and their change in early spring at Gosyõgahara Village in the north-eastern part of Katsuyama City, Fukui Prefecture, from Mar. 20 to Apr. 15, 1967.<BR>Observations were made on physical properties of snow cover, temperature, hardness, grain size, and free water content.<BR>Figures (3) - (10) in the text show the vertical profiles of hardness <I>R</I> (in g· cm<SUP>-2</SUP>), density <I>G </I>(in g·cm<SUP>-3</SUP>), grain size <I>D</I> (in m /m), free water content <I>W</I> (in %) and porosity <I>P</I> (in %), estimated from density and water content, of the deposited snow.<BR>Figures 17 (a)-(e) show mutual relation between hardness and porosity of the accumulated snow.<BR>From these investigations. a relation between hardness and porosity of the deposited snow was obtained as, <BR><I>R</I>=<I>Ae<SUP>-αP2</SUP></I><BR>Where <I>A</I> and α are positive constants.
