PERHAPS there is no better modern object-lesson on the real value of observing sanitary law than what has been accomplished in the Panama Canal Zone under the direction and efforts of Colonel Gorgas. The Journal of the American Medical Association is authority for the statement that the month of August, 1913, which marked the high tide of American occupancy of the Canal Zone, passed without a single death of disease in the American colony. Two Americans were killed by accident. When there was talk of cutting the great canal across the isthmus, much was said in regard to the impossibility of any but natives living there. It was thought that men could not be taken from this country who could live there any length of time. But the sanitary laws that are well understood by the up-to-date physicians of this time were rigidly enforced, and these marked results have followed. And in this connection, it is worthy of note that the laws of sanitation promulgated by Moses still stand at the head, which is, incidentally, a conclusive evidence of the divine inspiration that guided that great man of antiquity.
