The whole face of the country without distinction where it is left to nature is covered with vegetation sometimes so dense that nothing but an elephant can force a way through it sometimes scanty where the roots cleave rocks asunder and clamp stones together in the struggle to hold on till the rains enable them to creep farther afield and gain new size and strength

Estimating compressive strength General rock failure criterion can be reduced to a few parameters dependent on lithology m and the uniaxial compressive strength C 0Lithology is commonly derived during log analysis so m may be estimated Table 1What is needed still is an initial measure of rock strength provided by C 0 C 0 can be estimated from porosity or sonic velocities but many
