Continued a south-east course through large open plains thinly grassed; passed a dry watercourse with a small waterhole in one of the back channels, but insufficient for our horses, and at noon camped at a shallow waterhole in a grassy flat. Mr. Elsey walked half a mile to the eastward; came to a river eighty yards wide, but observing some blacks, returned to the camp. In the evening nine blacks came towards us, and appeared inclined to hostilities; but, after a short interview, retired up the creek. These blacks were not circumcised, and their teeth were perfect; they had neither ornaments or any description of clothing, and were slightly scarred on the back and chest. Their spears were large and heavy, made of a single piece of wood, and thrown by hand; they had also smaller ones of reed, with wooden points, which were thrown with the throwing board, which were flattened vertically; clubs two and a half feet long and two and a half inches in diameter, and shields formed of a single piece of wood two and a half feet long and three inches wide. The river proved to be fresh, and in pools separated by rock flats, and is evidently the same that Dr. Leichhardt supposed to be the Albert--a mistake which has caused considerable error in the maps of his route; as it was not named, I called it the Leichhardt. The character of the country is inferior, as the grass which covers the plains is principally aristidia and andropogon; anthisteria or kangaroo grass only in small patches. The soil is a good brown loam. Latitude by Vega 18 degrees 11 minutes 50 seconds. ATTACK BY THE NATIVES. 5th September.
