From power house No. 2 at sea level to LakeBuntzen is a distance of only one-half mile, but thedifference in elevation is no less than 500 ft. A further idea of the ruggedness of the countrycan be gathered from the fact that the new transmis-sion line, which follows the shore of Lake Buntzenfor approximately three miles, is in places but a few. Even the water for mixing concrete was packed on horseback. It was the original intention to construct thesteel towers right on the center line, but as the angleswould be too great for safety, this idea was laterabandoned as impracticable. The new line conse-quently crosses the old lines at several places, and atothers is directly overhead, causing considerable clqse. feet above lake level, while at others it is as high as500 ft. above it. This is due to the indented nature ofthe lake shore, along which are to be found at frequentintervals, high bluffs and crags. From the southerly end of the lake the line rap-idly reaches the highest altitude. The Summit, a 30 JOURNAL OF ELECTRICITY, POWER AND GAS [Vol. XXXII—No. 2 000 ft. above sea level. Here Mr. T. R.
