The “bacteria of fatigue” is the latest discovery of science,—found by Professor Gautier, of the French institute,—and certainly the most unobjectionable. Other bacteria have been doing us infinite damage, poisoning us through the water and the air and a multitude of other avenues. But here is the bacteria of fatigue, which intends no further harm to us than to remind us that we must take a rest. People who have been hitherto reviled and sworn at as lazy and worthless will smile. They know now what has been the matter with them. They have been treated most unjustly; for, in fact, they would have been just as active and industrious as others if they had not been victims of the “bacteria of fatigue.” In many cases they were attacked from birth—or, as the phrase is, were “born tired.” One of these, no doubt, was the young man about starting in life who wrote home to his father that he was well except that he “had a strange aversion to every species of exertion.” He did not know it, but in reality he was suffering with “bacteria of fatigue.” There are really thousands and tens of thousands with this malady all over the world, and especially in this country at the present time of the year in the rural roads. We call them tramps, but they are actually invalids, inoculated with Professor Gautier’s “bacteria of fatigue.” And for most of them there is no cure.
