SATURDAY, SEPTEMBER, 17 'ONTARIO TODAY : PAGE SEVENTEEN III a Pipeliners and wheat farmers often worked side by side More difficult conditions were met in Northwestern Ontario Mobile radio equipment was extensively used in the construction of the pipeline, a major undertaking requiring exacting schedules to complete in a two- year period, The most difficult construction was in northern Ontario, where rock of the Pre-Cambrian Shield meant constant blasting to dig a trench in which to lay and bury the 34-inch steel pipe. Near the Manitoba-On- tario border shale was encountered of such toughness that 30,000 sticks of high intensity explosives were required per mile to blast rock from the right-of-way and then from the ditch, Dense forest and rock-rimmed lakes added their own special problems which were typical of construc- tion through northern Ontario. Here and there the pipeline crews stumbled on evidence that earlier exca- vators had worked in their path. These were ancient diggings where Indians a thousand years before had mined vermilion-hued earth for warpaint, A ditch five feet deep was blasted through the rock of northwestern Ontario, after the right-of-way was cleared of rock outcroppings to permit the ma- chines which lay the pipeline to move in, A ditch was blasted under lakes and rivers so that concrete- weighted pipe could be laid on the bottom. Huge mobile cranes slid the weighted pipe into the water. Special buoyancy equipment kept the wood and con- crete-encased pipe floating across the lake or river till it could be joined up with the next land section. Then it was carefully lowered into the ditch blasted on the river or lake bottom, Pipeline construction crews with experience in many parts of the world came to Canada to help in laying this artery to bring new model fuel to eastern Canada. They brought with them ditching machines for use across the prairies and the agricultural sec- tions of Ontario.
