Extract from Article IX, Police Regulations 
ARTICLE IX 
Sec. io. No person shall remove or transport any 
manure over any public highway in any of the more 
densely populated parts of the District of Columbia 
except in a tight vehicle, which if not enclosed must 
be effectually covered with canvas so secured to the 
sides and ends of the vehicle as to prevent the manure 
from being dropped while being removed, and so as 
to limit as much as practicable the escape of odors from 
said manure. 
Sec. 20. Manure may be deposited in pits below 
the surface of alleys that are not less than fifteen feet 
wide, but the pit must not extend more than four feet 
beyond the building line. The walls must be substan¬ 
tial and water-tight, with stone or iron coping, bedded 
in cement, set fair with the surface of the alley. They 
must be covered with heavy wrought-iron doors, flush 
with the alley pavement or surface, sufficiently strong 
to carry heavily loaded carts or other vehicles, and pro¬ 
vided with ventilation by means of a flue inside of the 
stable and extending above the roof of the same, and 
they must be drained by sewer connections, as directed 
by the Inspector of Plumbing.
