not having been provided in proper proportion to the machinery of excavation. That the time required for the completion of the rock-cut was limited by the possible rate of transportation of spoil, and not by that of excavation, had long been known, and the report of the Board of Consulting Engineers contains elaborate diagrams of space available for shovels and for tracks. It was apparent, therefore, that the organisation of the work was not yet perfected. In like manner, as far as I could judge during my first short visit, the West Indian labour was not yielding the best results, owing to white foremen and coloured labourers not being in perfect harmony. [Illustration: THE CUT, LOOKING NORTH FROM CULEBRA.] [Illustration: THE CUT, LOOKING SOUTH FROM CULEBRA.] While, however, the fighting force, so to speak, of the Isthmian army was obviously imperfect in many respects, great results had evidently been achieved by the auxiliary services. The Department of Sanitation had already made the Isthmus healthier than most equatorial countries, food and quarters were excellent, law and order were well maintained. On the first day of my second and prolonged visit, April, 1908, fifteen months later, I went at once to the same spot on the Culebra Cut opposite to Golden Hill and again surveyed the scene of operations. The change was enormous. The gorge below me was greatly enlarged, the shape of the hills altered, the face of the landscape changed. As I gazed into the deep trench below, the thought flashed across my mind, "If my life be spared a few years longer, I will sail through this on a ship."
