now! greater safety and efficiency in total production, its total output in 1965 would be at the r a t e of approxi­ mately 5.5 trillion cubic feet a n n u ­ ally. I n m a n y consumer markets, even if n a t u r a l g a s prices rose substan­ tially, gas would still compete o n favorable terms with other fuels, particularly in Chicago, Cleveland, Detroit, Cincinnati, and other m a r ­ ket areas in t h e Mid-West. F o r example, in Cleveland a t the end of 1955, t h e prices of competing fuels for household consumption per mil­ lion B.t.u.'s, adjusted for t h e r m a l efficiency, w e r e : low volatile bitu­ minous coal, $1.50; high volatile bi­ tuminous coal, $1.30; No. 2 fuel oil, $1.56; and n a t u r a l gas $0.88. Moreover, even in areas such as New England, where n a t u r a l gas sells above other fuels, gas consump­ tion has continued to increase. I n Bridgeport, Conn., for example, comparative fuel prices p e r million B.t.u.'s in t h e household m a r k e t in 1955 were approximately: n a t u r a l gas, $1.59; coal, $1.38; a n d No. 2 fuel oil, $1.32. T h e fact that gas has found increasing consumer accept­ ance u n d e r these price conditions suggests that its convenience, cleanli­ ness, a n d efficiency will permit it to sell o n a competitive basis a t prices considerably above parity with other fuels in the household market. I n t h e light of these considera­ tions, we anticipate t h a t n a t u r a l gas prices will continue to move u p w a r d over t h e next 8 years, b u t perhaps not as rapidly as in the recent past. Average contract prices a t the well head should be a t least 5 to 10 cents per thousand cubic feet higher in 1965 than a t the present time. T h e u p w a r d movement will be, of course, influenced b y t h e regulatory poli­ cies of the Federal Power Commis­ sion. I n t h e long r u n , however, the prices will inevitably adjust to the levels indicated by d e m a n d a n d sup­ ply and will sooner or later take full cognizance of the relative utility of gas in the household market vs. other fuels. T h e growth in d e m a n d for L P G ' s is expected to continue, although a t a somewhat slower rate. I n a recent study, t h e Southwest Research I n ­ stitute h a s estimated L P G sales in 1965 at about 9.8 billion gallons. Various other sources have projected

PUMPING CORROSIVE FLUIDS

BART FLEXSEAL CENTRIFUGAL PUMPS At last—a full line of pumps specifically designed to handle corrosive and abrasive fluids in the 1 to"80 GPM range, at heads to 75 feet. No longer need you cut down bigger pumps in range and lose efficiency—or put up with undcpcndable smaller pumps. Bart pumps have fewer parts to wear or get out of order. Six models, each in corrosion resistant Type 20 Stainless Steel. Or other alloys on special order. Write for catalog and performance curves.

Heart of the BART . . . the exclusive Flex-Seal! Effectively minimizes a long-prev­ alent basic weakness of centrifugal pump design. Self-adjusting t o wear. Needs no external lubrica­ tion. Carbon stator/ceramic seat, u n e x c e l l e d for long w e a r — o r zircon filled Teflon/work-hard­ ened Type 20 S t a i n l e s s Steel, for severest corrosive service.
