ju^fS Vegas, Oct, 20, 1950. Comment on the results of HFC's scaling of pipe on the sheets of the Las Vegas Land and Water Company, 2-inch pipe. There is only one location of the 2-inch pipe on the Company's maps. It is my belief that when the Company tried to reconcile the 1949 annual report to the Bpvada Public Service Commission with the pipe totals, thi LA office found a suddenly new entry of 456 feet and did not know where to spot it on the maps* Am I right? 12-inch C,I. Pipe. The map showing pipe north of Charleston Blvd, is not very clear where the 12-inch pipe stops as it runs north on Main Street, I scaled it as 12-inch up to the 8-inch lateral pipe running east. 4-lnch C,I, Pipe. It is in this size that the largest discrepancy is shown by me, I am below the Company in both eases. If the reported lengths appearing in the annual reports to the PSC (copies of which I have since 1940) agree, then were places found on the maps for all the instal­lations? Average Ages. These were arrived at by using a unit known as the foot year, which when totaled and divided by the length of pipe, gives the average age. Same, for valves. Howard F.
