Excerpt from Mosquitoes: How They Live; How They Carry Disease; How They Are Classified; Hoe They May Be Destoryed Among summer residents of the country, and especially near the sea-shore, even before the agency of mosquitoes in the spread of disease became established, and before it became a generally accepted fact. With the very per feet proof that the mosquitoes of the genus Anopheles are instrumental in the carriage of malaria, the interest be came intensified, and the late discovery of our Army Yellow-fever Commission in Cuba, that a mosquito is the conveyor of yellow fever, has added to the general interest in the subject. In fact, the whole mosquito question is a live topic of the day. Knowledge of mosquito habits is more general than at any previous time, and almost every one is interested in the subject of mosquito extermina tion. Ivith the knowledge which we now possess, it seems almost incredible that people should all these years have suffered, more or less patiently, the torment ing bites of Culex and the insidious but more dangerous punctures of Anopheles without making the slightest ef fort to abate the nuisance and the danger, beyond slap ping, in a revengeful way, at individual biters. In many places infested with mosquitoes nothing could be easier than to put a stop to the whole tormenting plague. In many other cases the problem is a more difficult one, but in even the worst cases, by a judicious effort, which should be a community effort, and by the expenditure of a greater or smaller amount of money, much relief can be gained. In fact, Mr. W. J. Matheson, of New York, was quite right when, in the summer of 1900, just before com mencing a successful crusade against the mosquitoes on the north shore of Long Island, he wrote me that there.
