and fine specimens of agate were observed in many places along the basaltic ridges." On the 13th of February they discovered an important river, which was named the Isaacs, but it was not followed, as the course was again directed towards the mountains. Shortly after they had the good fortune to come upon the Suttor, which brought them to the Burdekin. This was the best discovery yet made, as it served them for a guide over more than two degrees of latitude. When this river also left them for the coast, their route was directed more inland, with a view of reaching Carpentaria. In this cross-country journey a conspicuous mountain observed in the distance received the name of Mount Lang "after Dr. Lang, the distinguished historiographer of New South Wales." A few unimportant creeks having been crossed, they found themselves on the western fall, and discovered one of the Gulf rivers, which was named the Lynd. Here, and at several later camps, the explorers were treated with a visit from some awfully pertinacious intruders.
