Note 2 — LETTER FROM DIEGO DE HERRERA TO FELIPE II

The number of islands and islets in the Philippine Archipelago is, according to G. R. Putnam, in charge of the U. S. Coast and Geodetic Survey in the Philippine Islands, 3,141. This number comprises everything, however small, which at high tide appears as a separate island. Of them, 1,668 are listed by name, while 1,473 are, so far as known, without names. More accurate information will doubtless further increase this number, which, as well as the following, cannot be regarded as yet as entirely definitive. The total area of the islands, so far as known, is 115,026 square miles. Two islands have areas exceeding 10,000 square miles each; nine of more than 1,000 but less than 10,000 square miles; 20, between 100 and 1,000 square miles; 73, between 10 and 100 square miles; 262, between one and ten square miles; and 2,775, less than one square mile each.
