The high tension lines of the company are to extendfrom the power house at St. Timothee, Que., to Montreal,in all a distance of 26 miles. These lines, consisting of eight cables, are to be carried on steel towers, the econo-mical height and spacing of vvliich was ligured to be 52feel and 500 feet respectively. \\ liile these heights and intervals of towers could befollowed throughout the greater part of the distance, theSt. Lawrence River, with its depth of water and rapid cur-rent, necessitated a special treatment. After an exhaustivestudy had been made and numerous soundings taken, thecompanys engineers decided to effect this by erecting onthe shore i>f the river steel towers approximately i:!0 feetin height, by building at the centre of the river twoconcrete piers extending about 15 feet above the meanwater level, and on these a tower 150 feet in height. The. Tower Placed Midway in .St. Lawreuee Hiver point at which the cables are to be carried across the riveris located almost 700 feet below the present C. P. R. La-chine bridge. At tliis spot the river is about 3,400 feetwide. As the soundings had located a shoal in the riveronly about 200 feet away from the centre, and as the waterat this point was only about 12 feet deep, it was decidedto erect the river piers at this point. This meant that thespan of the cables from the Caughnawaga side of the riverwould be feet, while that from the river tower to the
