YELLOW JACKS scoURGE.

Zones of the Fever and it's Cause and Treatment-Spanish Indifference to It Has Cost the World Millions, and Hundreds of Thousands of Lives-It
 Needs Persons Unused to the Tropics
 to Thrive and It Has Always Plenty
 of Such Raw Material.
 Yellow fever of the tropics is an acute specific fever Once developed it cannot be mistaken for anything else. It is infectious and ordinarily is not deemed contagious. A temperature of eighty degrees and upward is necessa- ry. Under certain atmospheric condi- tions, dependent upon great heat and moisture, conditions not thoroughly understood, it's poison is intensified and epidemics result. Its poison is very active and subtle agent easily trans missible
 In many localities it is endemic, due almost wholly to Spanish American in- difference to sanitary surroundings and a keen realization of the value of hu- man life. It's chief culture beds are Havana and Santiago in Cuba, Vera Cruz in Mexico, San Juan de Porto Rico, Colon, and Panama, on the Isth- mus of Panama. The disease is part and parcel of the seaboard cities named.
 | It's nearest habitat is Cuba Cuba | has it all the time, but it's chief center of activity is Havana, where it becomes an epidemic yearly in June, July and August, when sufficient unacclimated material is present. When very active in Havana during midsummer it is all most quiescent in eastern Cuba. In November December and January it l takes on it's greatest activity in Santi- ago. Such is the ordinary state of Cuba regarding yellow fever. At all times yellow fever may be found in some Cuban port. Also in the oldest cities, where pestilential conditions are
 very marked.
 | It's period of incubation or matching in the human body by some has been fixed at four to six days after landing in an infected center, or having been | exposed to it's poison through infected
 material Authenticated cases are ] known where the period of incubation
 has been fifteen days. Arbitrary laws may apply to some things, but the
 value is nil in tropical yellow fever. l As a general statement, yellow fever is a disease of newcomers in the tropical | belt. They have kept it active in Cuba | for over one hundred years. Men in ] full health, of good life and habits, fur | nish the greater part of its victims. | The newcomer in the tropics constant ly comes under new conditions, both
 natural and physical. The natural | conditions become tax on an organ | ism previously in full health. In tenn perate climates there is an equipolse, | the internal organs doing their own l work under normal conditions. In the | tropics changes in the tissue muse fol- low If the individual is to stay in them
 and become wholly acclimated or l adapted to the new conditions. The
 nice balance of power Is upset. Many
 unduly expose themselves to the
 scorching sunlight Others expose
 themselves to the heavy dews. Many | indulge in the fully matured juicy l fruits of the tropics, thereby unduly | upsetting the already overtaxed inter- nal machinery. A fever of some kind
 ia a mere question of weeks or months.
 It may be simple malarial fever-a

There are severe head | aches, generally across the forehead; pain low down in the small of the back, frequently of an excruciating kind. No position gives any rest Inquiry devel- ops the fact that a well-marked chill precedes the headache and general ma
 laria. The length and severity of the
 chill have marked significance. In-
 tensity of it means a troublesome case.
 Briefly stated, such are the general symptoms leading up to a case of vel
