twenty -four inches square at the top, laid to sidewalk grade thirty
(30) inches square at the bottom, with a thickness of twenty -four

of the concrete base shall be floated and troweled smooth. The
foundation must be given at least seventy -two (72) hours to set
before the post is placed thereon. The center of the posts shall
be set twenty -one (21) inches from the curb face, unless otherwise
shown upon the plans or in the Resolution of Intention. They shall
be plumb and in line, and of the same relative height above the
curb. After plumbing the posts upon the foundations, the base
must be given a uniform bearing by Fouting with a mixture of one
(1) part Portland Cement and two (2) parts sand, the grout being
thin..,enough to flow.

twelve (12) inches below the top of the curb, and at street inter-
sections shall be laid not less than twenty -four (24) inches below
_ the finished grade of the street, except when laid beneath a con -
crete gutter or permanent pavement, in which case the conduit shall
be at least twelve (12) inches below the finished grade.. Conduit
