The Boughen Engineering Company of Cincinnati, O., are having a very busy season. They have just completed a waterworks plant for the Consolidated Distilling Company of that city, which was a work requiring a great deal of skill and good management. The pumping machinery consists of a Gordon duplex vertical pumping engine of 1,000,000 gallons capacity, steam cylinder being sixteen inches in diameter by eighteen inch stroke ; the water ends, twelve inches in diameter by eighteen inch stroke ; the water ends rests fifty feet below the steam end in the bottom of a pumping well ten feet in diameter; the machinery, complete, weighs about 17,000 pounds. The pump draws the water from the Ohio river, a distance of nearly 2000 feet, pumping same through distributing pipes through the various buildings of the distillery and also into a large tank elevated on the roof, capable of holding about 15,000 gallons. The suction pipe is a ten-inch [pipe and laid almost entirely under water. Commencing at the pumping well, which is ten feet in diameter by sixty feet deep, there is a tunnel driven through from the well to the bank of the creek, the bottom of same being about 2 1/i feet above extreme low-water mark. The tunnel is about 125 or 130 feet in length and it was necessary to do all of the work at the period of the lowest stage of the river. The size of the tunnel is five feet in height and 2]⅛ feet wide at top, and 3 1/2 feet at the bottom, with a sheeting throughout of three inches solid oak lumber. This was a very dangerous piece of work, as a great deal of it was filled ground, being simply ashes from the boiler plant of the distillery dumped over the bank and fifty feet or more of it adjacent to the well being pure sand, which necessitated very careful handling of the work in order to avoid a run. This work was prosecuted from both ends. After the completion of the tunnel the work of erecting the machinery and laying the pipe.was completed in fourteen days from the time pipe was unloaded from the cars until the machinery was ready to start pumping water. The pipe used was ten-inch screwed pipe for the suction, coated with asphaltum varnish inside and outside. In laying the pipe, gangs were started from each end, working from the river up the creek and from the tunnel down the creek. In the creek the pipe was put together on a series of trestles, as shown in illustration, as each length was added to it the line was let down into the water and another gang then followed up with shovels and scrapers and took out the sand from underneath on each side, thereby allowing the current, which was very swift, to help wash out the trench into the bed of the creek. This the first slight rise will fill completely with sand, covering it entirely up in the bottom of the creek. From the river end it was necessary to go some 600 ot 800 feet above the mouth of the creek in order to get above a sixteen-foot sewer which empties into the river at this point. The pipe in the river was put together on floats, the hook end around the pier being left out of the water until the pipe was entirely connected together, this, by not allowing the entrance of any water in the pipe, kept it afloat by the bouyancy of the air contained therein until the entire length in the river of some 600 or 800 feet was connected together, then by selecting a level bed along the bottom of the river and filling the pipe with water, it was sunk to the bottom. Afterwards it was found that at the mouth of the sewer, although the pipe was some seventy-five or eighty feet away, there was an exceedingly strong current, and in order to secure this from any liability of being washed or broken, it was deemed best to anchor it in the same manner. This was done by securing heavy bands around the pipe and attaching two heavy log chains, the other ends of which were anchored in masonry work in the mouth of the sewer tunnel. In addition to this, several very heavy pieces of cast-iron were chained to the pipe, being the weight of several tons. The tank on roof of building was then filled with city water, and, by means of by-passes arranged from suction to discharge of pump, the whole thing was flushed out expelling all air that was left in the pipes. The pump* were then started and test made which was entirely satisfactory and considerably beyond the guarantee. The Boughen Engineering Company also expect to be ready shortly to test the works at I'ontiac, 111., which they report about completed, as far as their work is concerned.
