want of generalship by which they have been allowed to burn the white man's dairy station and stockyards on the banks of the Bogan. The establishment of a police station near the junction of the Bogan with the Darling, or the formation of an inland township about Fort Bourke, had been sufficient to have secured the stations along the Bogan and Macquarie, and to have protected the Bogan natives as well as our own countrymen from frequent robbery, murder, and insult. Such are the results where SQUATTING has been permitted to supersede settling. With possession, deficiency of water in dry seasons had been remedied, and no such debateable land had remained on the borders of a British colony. The part of the Bogan where least water can be found, has always been that between our present camp and Muda, a very large lagoon about 50 miles lower down. I found by the barometer that there is a fall of 206 feet in that distance of 50 miles; whereas the fall in the bed of the Bogan is only 50 feet between Muda and New Year's Range, in a distance of upwards of 100 miles. The general course of the Bogan changes at Muda from N.W. to north, the former being nearly in the direction of the general declination of the country, the latter rather across it, of which the overflowings of the parallel river Macquarie into Duck Creek, and other channels to the westward, seemed to afford sufficient proofs. Where the declination is least, the water is most likely to remain in ponds in the channel of the river after floods, the water of which can neither flow with so much velocity, nor bear down any of the obstructions by which ponds are formed. Mr. Dixon found the velocity of the Bogan at this part, during a flood in 1833, to be four miles in an hour; which is about double the average rate of the larger rivers of Australia. I had an order from Mr. Kerr, the proprietor of this station of Derribong, to his superintendant, for such fat cattle as I might require to take with me as live stock. Finding that the sheep answered very well, having lost none, and that they rather improved in travelling, whereas the working oxen had been much jaded and impoverished by the long journey, heavy loads, and warm weather; I determined to take as many young bullocks as might suffice to relieve and assist the others, and break them in as we proceeded. 30TH DECEMBER.--The wind changed to S.E., and brought a cool morning. Thermometer, 68 deg.. This day we selected from the herds of Mr. Kerr 32 young bullocks, and they were immediately yoked up in the stockyard. Received letters from Sydney, by Corporal Graham. 31ST DECEMBER, 1845.--Thermometer at 5 A. M., 62 deg.: at noon, 109 deg.. Wind S.E. At noon a whirlwind passed over the camp, fortunately avoiding the tents in its course; but it carried a heavy tarpaulin into the air, also some of the men's hats, and broke a half-hour sand-glass, much wanted for the men on watch at night. The sky overcast from the west in the evening.
