We now proceed to a more minute examination of the contour of the coasts. It is to be observed that on the north of the Great Java, as shown in all of these manuscript maps which have met the editor’s eye, occurs the word “Sumbava,”—a fact which, he thinks, has never been noticed by any writer upon these interesting documents. Here is another instance of the discovery of the north of an island of which the south has remained unexplored. The peak of the Great Java, on which this name “Sumbava” is laid down, falls into the right position of the now well-known island of Sumbava, with the smaller islands of Bali and Lombok, lying between it and Java, and with Flores and Timor duly described to the eastward. The reason of this south coast of these islands remaining so long unexplored may be found in the description of Java by Barros, the Portuguese historian, who wrote in the middle of the sixteenth century. He says: “The natives of Sunda, in dissecting Java, speak of it as separated by the river Chiamo from the island of Sunda on the west, and on the east by a strait from the island of Bali; as having Madura on the north, and on the south an undiscovered sea; and they think that whoever shall proceed beyond these straits, will be hurried away by strong currents, so as never to be able to return, and for this reason they never attempt to navigate it, in the same manner as the Moors on the eastern coast of Africa do not venture to pass the Cape of Currents.” The earliest mention that the editor has noticed of a passage to the south of Java, is in the account of the “Four Hollanders’ Ships’ Voyage, being the First Voyage of the Dutch to the East Indies.” See _Oxford Collection of Voyages_, vol. ii, p. 417. Under date of the 14th March, 1597, it is said: “The wind blew still south-east, sometimes more southward and sometimes eastward, being under 14°, and a good sharp gale, holding our course west south-west. There we found that Java is not so broad nor stretcheth itself so much southward as it is set down in the card; for, if it were, we should have passed clean through the middle of the land.” Supposing, then, that the Portuguese navigators have lighted upon the west coast of Australia, and have regarded it as a possible extension to the southward of the already known island of Java; let us proceed to test the correctness of this supposition by the contour of the coast of the western side. A single glance of the eye will suffice to detect the general resemblance. It is probable that the two great indentures are Exmouth Gulf and Shark Bay, and we may fairly conclude we detect Houtman’s Abrolhos in about their proper parallel of from 28° to 29° south latitude. To attempt a minute investigation of the whole coast upon data so indefinite would be of course unreasonable, but on this western side at least the similarity is sufficient, we think, on every ground to establish its identity with the west coast of Australia.
