Don't forget that subsoil drains arc made of fragile pipes with a lu!avy weight of metal above them in a soft country (F. M. S. and Straits), and that inspection points along the drains should be provided in order to ascertain from time to time that they are in working order. I. Don't lose sight of the fact that the subsoil drain was proved to be a most valuable anti-malarial measure in Panama by H. Simms. m. Don't forget any of the component parts of the classical subsoil drain (as has been done in many places). a. The ditch (deeper than the stream by 2' Simms). b. The i^ipe (never less than 4). c. The mattress of straw* in the case of Panama, lalang in this country (almost invariably omitted here). d. The large metal (3 to 5 grade). e. The small metal (1 to 2 grade). /.

Manj'- instances of the infection of new houses, sites, and even areas can be quoted, the infection being simply due to the fact that 50% of the workers were saturated with malaria, and while living on the site they saturated the Anophelines. Let us now pass on to the consideration of the conditions most suitable for the maintenance of the health of the labour force re- membering always that tJbe more healthy the estate the easier it will always be, not alone to obtain labour, but to retain it, and even in some cases to build up weedy coolies so that they become valuable assets. The Coolie's Health. Laws i^ou Lines. There are certain fundamental necessities for the establishment of a healthy labour force. 1. A pure water supply. 2. Adequate ventilation. * over the joints.
