Dr.Sambon and a friend lived in this district from June 1 to September 1, 1900.

The test was whether they could live in this exceedingly dangerous climate for the three months without catching malaria, if they used stringent precautions against the bites of mosquitoes.

For this purpose the hut in which they lived was thoroughly wired, and they slept under netting.
Both of these gentlemen, at the end of the period, had escaped the disease.
Then came the fifth and final triumph--the prevention of the disease.
The anti-malarial crusade which has been preached by Sir Ronald Ross and has been carried out successfully on a wholesale scale in Italy and in parts of India and Africa, has reduced enormously the incidence of the disease.

Professor Celli of Rome, in his lecture room, has an interesting chart which shows the reduction in the mortality from malaria in Italy since the preventive measures have been adopted--the deaths have fallen from above 28,000 in 1888 to below 2000 in 1910.
There is needed a stirring campaign against the disease throughout the Southern States of this country.
The story of yellow fever illustrates one of the greatest practical triumphs of scientific medicine; indeed, in view of its far-reaching commercial consequences, it may range as one of the first achievements of the race.

Ever since the discovery of America, the disease has been one of its great scourges, permanently endemic in the Spanish Main, often extending to the Southern States, occasionally into the North, and not infrequently it has crossed the Atlantic.
