But the protecting of the Filipino against himself is not always easy. A short time ago there suddenly broke from the ground on the outskirts of Manila a new spring of water which quickly acquired a reputation for possessing magical healing properties. The water was amber-colored, and possessed a taste which alone was proof enough of its medicinal value. So the natives flocked to drink of the new water and be cured of their various13ailments; and among them, as they gathered in increasing numbers, cholera began to rage. The attention of the authorities was thus called to the subject, and it was found that the new spring came from nothing other than leakage from a sewer. Manila itself now has the “two great factors essential to public health;” namely, an assured pure water supply, and a modern and adequate sewer system. And one of the most delightful short trips to be made from the city is the twenty-two mile drive (best done in an automobile) out to Montalban, where the superbly impressive gorge of the Mariquina River is blocked by a massive concrete dam, and the river has been diverted (at a cost of some £800,000) to furnish Manila with pure water.
