This photograph has four images. The first one (0272_0052) with the upside-down picture, has a handwritten inscription that reads, "View of hi-line and carriages on a double cable. First used on buckets. Was a little slow. These hi-lines stretching across the dam on a huge cable. Consist of several small cables in center, weaved together. In the center, outside, the carriages ride on smooth surface of one inch wide steel strips wrapped around the cables for a tight and smooth surface." The second image (0272_0053) reads, "'Pipe fitters' raising air and water pipe to a higher elevation for easier access." The third one (0272_0054) reads "'The water bag', a very popular item on Dam. Warning signs placed around, 'Do not drink water from taps on dam'. Arsenic in the water and in the mts. Once you get an open cut, you must avoid getting water from the dam in it. You have a good chance of arsenic poisoning. A boy in my dormitory got it. He broke out in sores at some spot. After long treatments it would heal, but two or three weeks break in another spot. Once in the blood, too bad." The fourth image (0272_0055) reads "Another good view. Stiffleg making a pour on dam nearest and #7 working in a lower pour - pours are numbered - from face to upstream face. 1-2-3 etc. across from wall to wall by alphabet, the slot (center) is between J & K."
