Jewett C. Gilson, Wealth of the World's Waste Places and Oceania
“ As islands go, Guam is of fair size, about thirty miles long and from three to ten miles in width. It is mountainous and the surface is jungle-covered except where the natives have made trails and clearings. Fringing coral reefs, broken here and there, encircle the island. One of these breaks is opposite a bight in the coast, San Luis d'Apra, or Apra, as it is now called; and the bay and channel together form a harbor so well guarded that no transport laden with hostile troops would ever attempt landing. ”
