A certain number of men, when they were given their daily dose of quinin in the dispensary, would manage to throw their tablets out of the dispensary window. The old turkey-gobbler that was the pet of the hospital seemed to like the stimulating effect of the quinin and gobbled up all the tablets he could find. He became so dissipated in this way that he finally developed quinin amblyopia. This amblyopia is a species of blindness that is sometimes caused by too much quinin. The doctor finally had to confine his old gobbler and keep him away from quinin tablets until he recovered his sight. I cannot vouch for this story, but I was often twitted with it as an illustration of how the men were treating prophylactic quinin. Even if this story were true, it could not be used as an argument against prophylactic quinin on the Isthmus. In general, no attempt was made at compulsion, and there would therefore be no object in a man taking quinin and throwing it away. I have noted before that our hospital system was planned upon the scheme of some forty sub-district hospitals, or rest camps, which fed about twenty district hospitals. These twenty district hospitals, by means of hospital trains, fed two base hospitals, situated respectively at the northern and southern end of the Canal, Colon and Panama. The one at the southern end was much our largest hospital, containing at its maximum about fifteen hundred beds. The city of Panama is situated on a peninsula, stretching into the bay of Panama. Just north of the city rises Ancon mountain, some six hundred and fifty feet in height. This mountain is only accessible to a pedestrian; the trail is too rough and precipitous for horse or mule. The northern suburb of the city of Panama is known as Ancon, and this village nestles about the southern foot of Ancon mountain. The line dividing United States territory from Panama passes between Ancon and the city of Panama. Ancon is therefore under the jurisdiction of the United States. Ancon Hospital is beautifully located along the southern and eastern front of Ancon mountain. The French early in their construction period, about 1882, commenced building their main hospital there. The side of the mountain was graded for roads and laid off in the most beautiful and picturesque manner. Every variety of tropical shrub and plant was introduced from other parts of the tropical world and planted around the grounds. Every opportunity for picturesque location of buildings was seized, and over thirty hospital buildings of various kinds were located over a large area, extending along the northern and eastern sides of Ancon mountain.
