 of silos for this crop, and the relative density of the silage at dif-
 ferent depths.

 The depth of settled silage was measured in each of the silos
 when opened. The one-ton silos were measured at least once
 daily as the silage was removed. The depth of silage in the
 upright 20-foot silo was measured at five-day intervals. All cal-
 culations were based on the total weight of silage removed and
 the number of cubic feet occupied by it. The relative densities of
 these silages in the one-ton silos and in the upright silo are pre-
 sented in Tables 24 and 25.
