         with them.  Swarms of grasshoppers were seen on each day.
        All gardens in the city were devastated...and in the
        countryside the grasshoppers were very destructive to ripened
        grain.  On the 30th the grasshoppers were so numerous as to
        almost darken the sun.

        Hail stones as large as partridge eggs accumulated to a
        depth of 1 1/2 feet over eastern portions of the city.

        inch in central Denver.
