After one storm in May of 1884, the fluviograph at Gamboa had recorded a rise of ten feet in twenty-four hours.
He had watched the dredges in action; he had been to the top of the fluviograph at Gamboa, a picturesque, brightly painted tower where watch was kept of the temperamental Chagres and where, on a small platform enclosed by a fancy gingerbread railing, he had been able to look out over the treetops as his French hosts expounded on their plans.
In the rainy season, under normal conditions, the discharge would be ten times that–or more–with fluviograph readings of 10,000 to 13,000 cubic feet per second.
Here dwells hale and ruddy "Old Fritz," for long years keeper of the fluviograph that measures and gives warning of the rampages of the Chagres.
