carried down by the floods. The river banks were covered in many places 
with green grass. The trees on the banks still retain their green foliage, and 
undoubtedly this is the finest part of the river. The camping places of natives 
were more numerous, and heaps of mussel-shells were strewed round their 
fires. The tide was now at ebb, so we filled every article that could be made 
to hold water and started down the river again, considerably refreshed. In 
passing I landed at the western and eastern angles ; at the former there were 
no trees marked; at the latter Mr. Gregory had marked some trees, dated 
September 2nd, and had buried more letters, which I procured, and reached 
the tall palm-trees at 8 p.m., when meeting the flood- tide, we camped for the 
night; 
Nov. 1 Qth . — Started at 5 a.m. with the first of the tide, having had a restless 
night caused by the mosquitoes ; passed the 30 feet cliffs, through Island Reach, 
and within four miles of the junction near the salt-water arm. At 5 p.m., the tide 
having turned, we encamped on a high, soft, mud-bank by the side of the river, 
the only spot within some miles that was free from mangroves. Although these 
banks are some feet above high water, yet the surface of them is quite soft, 
with a sticky kind of bluish clay covered with a coarse grass. After supper 
we rolled ourselves up in our blankets, and lay down for sleep, but no sooner 
did it become dusk than our old enemies, the mosquitoes, commenced in 
sueh good earnest, that we were forced to take to the boat. Every precaution, 
even a smoking fire, appearing useless, we pulled down to the junction and 
came to again, to wait for the turn of tide. 
Nov. YUh . — We were all very glad when the tide turned, for the mosquitoes 
drove away all sleep. We started at 3*30 a.m. with a good flood-tide, passed 
all the Mangrove Islands, and seeing a good clear part of the bank on the left 
side, about seven miles from the entrance of the river, we landed and had 
breakfast. At this part of the river a small sandy alluvial plain descends, 
having a bank about 20 feet high. At the foot of this, at low water, the bed 
is seen covered with numbers of shells of many genera — areas, cytheras, 
barnacles, &c. Trees were scattered here and there among them. We reached 
Kangaroo Point by 9 a.m., pushed out over the bar, and it being very low- 
water, we had to drag the boat about 1J mile over the bar, but in two hours 
after leaving Kangaroo Point we reached the vessel, December 16th, 1857.
