Note 2 — VII
Reading edition
According to the report of an engineer, the sand banks are caused by the river San Mateo, which runs into the Pasig at right angles shortly after the latter leaves the Lagoon; in the rainy season it brings down a quantity of mud, which is heaped up and embanked by the south-west winds that prevail at the time. It would, therefore, be of little use to remove the sandbanks without giving the San Mateo, the cause of their existence, a direct and separate outlet into the lake.
