A sample of moist sand was cut out of a natural deposit by means of a sampling
cylinder. The volume of the cylinder was 478 ml; the weight of the sample alone was
884g and 830g after drying. The volume of the dried sample, when rammed tight
into a graduated cylinder, was 418 ml and its volume, when poured loosely into the
same cylinder, was 616 ml. If the particle specific gravity was 2.67, compute the
density index and the degree of saturation of the deposit.
