The admittance and drainage of water into reservoirs are controlled by movable gates fixed in the dyke. Sea-water may be allowed to remain in the reservoirs for evaporation for some time before it is conveyed into the concentrating ponds by means of an irrigation-wheel or a bamboo-bucket. When about three inches of sea-water have been bailed into the first two concentrating ponds and have been allowed to evaporate for a day or two, the brine is run into the next two ponds by gravity. One pond communicates with the other by means of a short bamboo-pipe, laid in some suitable point of the mud-ridge, to allow the water to go through, and the water from one pond can be stopped from going to the other by inserting a straw-plug into the upper end of the pipe. When the brine is sufficiently concentrated by evaporation it is finally run into the crystallization
