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.
