HEALTH OFFICE REGULATIONS FOR CONTROL OF HOUSE FLIES IN CITIES.

All stalls in which animals are kept shall have the surface of the
ground covered with a water-tight floor. Every person occupying a
building where domestic animals are kept shall maintain in
connection therewith a bin or pit for the reception of manure and,
pending the removal from the premises of the manure from the animal
or animals, shall place such manure in said bin or pit. This bin
shall be so constructed as to exclude rain water and shall in all
other respects be water-tight, except as it may be connected with
the public sewer. It shall be provided with a suitable cover and
constructed so as to prevent the ingress and egress of flies. No
person owning a stable shall keep any manure or permit any manure
to be kept in or upon any portion of the premises other than the
bin or pit described, nor shall he allow any such bin or pit to be
overfilled or needlessly uncovered. Horse manure may be kept
tightly rammed into well-covered barrels for the purpose of removal
in such barrels. Every person keeping manure in the more densely
populated parts of the District shall cause all such manure to be
removed from the premises at least twice every week between June 1
and October 31, and at least once every week between November 1 and
May 31 of the following year. No person shall remove or transport
any manure over any public highway in any of the more densely
populated parts of the District except in a tight vehicle, which,
if not inclosed, must be effectually covered with canvas, so as to
prevent the manure from being dropped. No person shall deposit
manure removed from the bins or pits within any of the more densely
populated parts of the District without a permit from the health
officer. Any person violating any of the provisions shall, upon
conviction thereof, be punished by a fine of not more than $40 for
each offense.

Not only must horse stables be cared for, but chicken yards, piggeries,
and garbage receptacles as well. In cities, with better methods of
disposal of garbage and with the lessening of the number of horses and
horse stables consequent upon electric street railways, bicycles, and
automobiles, the time may come, and before very long, when window
