W. C. Gorgas and George W. Goethals, whose combined work gave the canal to the world.] Wallace at the very outset had to overcome one grim and unrelenting enemy which was largely subdued before his successors took up the work. Yellow fever and malaria ravaged the Isthmus, as they had done from time immemorial, and although Sanitary Officer Gorgas was there with knowledge of how to put that foe to rout the campaign was yet to be begun. They say that Wallace had a lurking dread that before he could finish the canal the canal would finish him, and indeed he had sound reasons for that fear. He found the headquarters of the chief engineer in the building on Avenida Centrale now occupied by the United States legation, but prior to his time tenanted by the French Director-General. The streets of the town were unpaved, ankle deep in foul mire in the rainy season, and covered with germ-laden dust when dry. There being no sewers the townsfolk with airy indifference to public health emptied their slops from the second-story windows feeling they had made sufficient concession to the general welfare if they warned passersby before tilting the bucket. Yellow fever was always present in isolated cases, and by the time Wallace had been on the job a few months it became epidemic, and among the victims was the wife of his secretary. [Illustration: A WALK AT ANCON] [Illustration] [Illustration: IN THE HOSPITAL GROUNDS] However, the new chief engineer tackled the job with energy. There was quite enough to enlist his best energies. It must be remembered that at this date the fundamental problem of a sea level _vs._ a lock canal had not been determined--was not definitely settled indeed until 1906. Accordingly Engineer Wallace’s first work was getting ready to work. He found 746 men tickling the surface of Culebra Cut with hand tools; the old French houses, all there were for the new force had been seized upon by natives or overrun by the jungle; while the French had left great quantities of serviceable machinery it had been abandoned in the open and required careful overhauling before being fit for use; the railroad was inadequate in track mileage and in equipment. Above all the labor problem was yet to be successfully solved. In his one year’s service Wallace repaired 357 French houses and built 48 new ones, but the task of housing the employees was still far from completed. Men swarmed over the old French machinery, cutting away the jungle, dousing the metal with kerosene and cleaning off the rust. Floating dredges were set to work in the channel at the Atlantic end--which incidentally has been abandoned in the completed plans for the canal though it was used in preliminary construction. The railroad was reëquipped and extended and the foundation laid for the thoroughly up-to-date road it now is. Meanwhile the surveying parties were busy in the field collecting the data from which after a prolonged period of discussion, the vexed
