""One-sixth of the natives of Luzon have either been killed or have died of the dengue fever in the last few years. The loss of life by killing alone has been very great, but I think not one man has been slain except where his death has served the legitimate purposes of war. It has been necessary to adopt what in other countries would probably be thought harsh measures."--General James Bell, May 3, 1901, New York Times explaining why one-sixth of the population of Luzon had died in the previous two years of the Philippine insurrection."
