unloading point for ocean ships. They built 21 A-frames to hold the cable, from which were suspended three self-propelled cars, each capable of hoisting 10 tons of pipe or other cargo.

Operated in tandem these automotive hoists of the high wire made the three mile journey in five minutes, and they brought ashore 1,100 tons a day, swinging it along 80 feet above the water.

Transportation of the pipe from California to Ras el Mishaab having thus been solved, the next thing was to get it out onto location. Field welding was a terrific problem, with the necessity of moving the welding equipment each time two pipe ends were joined. So that problem, too, was conquered.

As soon as the nested pipes were brought ashore at Ras el Mishaab a special machine, invented and manufactured for the purpose as so many machines were on this whole project, denested the 30 from the 31-inch pipe. Then three lengths were automatically welded on the base, making lengths of about 93 feet each for moving onto the job.

Long before the first black goathair Arab tent had been raised at Ras el Mishaab, the engineers and executives back home had been figuring out problems to be met in advance. Trucks and trailers too wide and too heavy for any United States highway had been built and
