—Having received several inquiries in regard to the details of the system of sewerage and epuration in operation at Pullman in the vicinity of this city, we answer as follows: The population of the town is about 8,000. The sewerage matter is received into a system of deep laid sewers through which it is conducted into a large cesspool, from which it is pumped through a large cast iron pipe to the farm, a distance of 15,500 feet (about three miles), where it is received into a tank, screened through ½ inch screen to separate out the coarser matter contained in it. From the tank it is distributed over the farm through clay pipes laid four feet below the surface, with hydrants every 400 feet to carry it to the surface over which it is allowed to flow.
The farm has 140 acres capable of being irrigated through these pipes
