weighed entire seventy pounds, and without the entrails sixty-six pounds: it is somewhat singular that in none of these fish is any thing found in the stomach, except occasionally a shrimp or two. The dimensions of this fish were as follow: Feet. Inches. Length from the nose to the tail 3 5 Circumference round the shoulders 2 6 Fin to fin over the back 1 5 Circumference near the anus 1 9 Breadth of the tail 1 1 1/2 Circumference of the mouth opened 1 6 Depth of the swallow 1 foot. Most of the other fish taken this evening weighed from fifteen to thirty pounds each, and were of the same kind as the above. May 7.--A fine clear frosty morning. The horses having been much fatigued by the two last days' journey, I determined to halt to-day instead of Saturday, as the grass was good, which is more than could be said of it for some days past. Observed the latitude to be 33. 22. 59. S. May 8.--Proceeded down the river. Our general course was westerly, and the country, though equally level with any we had passed, improved in the quality of the soil, which, during the greater part of to-day's route, was a good vegetable mould, the land thickly covered with small acacia and dwarf trees. On the south side of the river it was apparently the same; and the whole we passed over bore evident marks of being subject to inundations. The banks of the river were, I think, much lower, not exceeding fifteen or twenty feet high, and they were rather clearer of timber than before. The casuarina, which used to line the banks, was now seldom seen, the acacia pendula seeming to take its place. We stopped for the night on a plain of good land, flooded, but clear of timber: large flocks of emus were feeding on it, and we were fortunate enough to kill a very large one after a fine chase. At three o'clock, the boats not having arrived, I sent a man back to look for them; at eight he returned, having found them about six miles up the river, unable to proceed until morning, having met with continual interruptions from fallen trees. These impediments in the navigation of the river obstruct our progress very materially, and its windings continue so great and frequent, that the distance travelled by land is nearly trebled by water. May 9.--The boats not having arrived at ten o'clock, Mr. Evans proceeded with the BAT horses another stage down the river. Mr. Cunningham and I waited to bring up the boats, which shortly afterwards came in sight. We proceeded to join the horses, which we did about five o'clock, the boats having gone in that time nearly thirty-six miles, although the distance from the last station did not exceed seven in a direct line.
