The visit to Kangaroo Island extended over the period August 3rd to August 22nd, and that to Western Eyre's Peninsula over the period October 15th to October 20th, 1912. In both areas a rapid geological reconnaissance was made of the particular portions of the districts in which discoveries had been made of materials which led to the belief in the presence of mineral oil. It will be seen that the data acquired during this work of reconnaissance are not such as to warrant a more detailed investigation of any portion of the districts visited with the special object of selecting sites for boring operations.
