The guard gate, Gatun Lock

Pennell, Joseph, 1857-1926 · 1912

"There is a safety gate in each lock, to protect in case of accident, the main lock gate, just suggested, with the figures working at the armor-plate facing, on the extreme right. Beyond are the outer walls and approaches of the upper lock, and beyond these, but unseen, the lake. The scale, the immensity of the whole may be judged by the size of the engines and figures. I have never seen such a magnificent arrangements of line, light and mass, and yet those were the last things the engineers thought of. But great work is great work, and always was and will be. This is the Wonder of Work." Joseph Pennell.
