Cofflnan, Jr. , Pacific Sewer Pipe Comp; 825 East 7th Street, Los Angeles, California C ompany, Sales Manager Pear Sir / Regarding the 16" pipe &6ld to the Salt Late Railroad for water line at Las Vegas, Nevada, I inspected the whole line with Mr. McGuire, Chief Engineer of the Salt Lake Route on November 24th, 191?. This is in conformity with Mr. Poster's letter of November 17, 1917. from an engineering standpoint?, in the way that their en­gineer, C. S.

According to the story told me, the 16" valve was closed and the 8* valve left open to relieve the pipe line of air when the column of water was turned down the pipe line two miles away. On the first test, the pipe burst at J one place which they estimated had about 19$ pressure. This pipe was replaced and the second test was made. The pipe ruptured in three different places, in one case the pipe burst at 6# pressure. Both Mr. McGuire and my­self feel confident that this was a cracked piece of pipe that was put into the line by oversight by the contractor, and had nothing to do with the strength of the pipe in general, as the other pipe in the line with three times a-.§ much pressure, held without any rupture. I find that the pi/e has not been installed I find in making the tests and talking with
