awarra palms, though high land covered with immense 

 forest trees lay at the back, and in many places abutted on 

 the banks. The channel at intervals opened out into wide 

 lake-like areas, chiefly at the bends or " points," and again 

 narrowed in places to from 10-20 yards. A few miles 

 above Mappa the high land predominated, and the trap 

 rocks (greenstone) began to outcrop along the banks, 

 though the height of the water effe6lually obscured the 

 extent of the formation. Along these portions, the fallen 

 trees in the water became very numerous, though not 

 sufficiently so as to block the channel. 



On the morning of Saturday, the 20th, we passed 

 some Indian houses on the East bank where the Indian 

 wood-cutters were engaged with SiMON, and soon after 

 came in sight of Mr. KINGSTON'S residence at the grant 

 at Cooroodoonie — the last inhabited place on the river. 

 A day's journey above this brought us to Idure Wadde 

 creek, which opens on the East bank, and on which, not 

 far from the mouth, a lovely cascade is found, where the 

 water tumbles in a longcatara6l over the trap rocks for a 

 total difference of height of about 20 ft. The roaring 

 of the water can be easily heard from the river 

 some little distance down, and the cascade is most 

 easily reached by striking through the forest where 

 the sound is loudest. Soon after passing Idure Wadde, 

 on the 23rd, the first rapids of Marlissa — pronounced 

 Marlisha by the Indians — were met with, and after 

 paddling and pulling through eight of these, formed 

 by dykes of granite and quartz-porphyry, where in the 

 majority of cases the channel was extremely shallow, 

 much obstru6led with stones, and the last one ex- 

 tremely narrow and leading from a circular lake, we
