The number of individuals of which the expedition down the banks of the Macquarie was composed, was fourteen: that is to say, myself, Mr. Hume, two soldiers, one free man, and seven prisoners of the crown. The latter behaved, on all occasions, as steadily as it was possible for men to do. Yet the circumstance of the two soldiers being with me increased my confidence in the whole, for I was aware that their example would influence the rest. However well disposed the prisoners of the crown may be, (as in this instance they certainly were,) the beneficial example of steady discipline cannot be denied. I should not have considered myself justified in leaving the camp as I did for a week, and in detaching Mr. Hume at the same time when at the bottom of the marshes, or in making the last effort to maintain our position on the banks of the Darling, if I had not reposed every confidence in the man to whom I entrusted the safety of the camp during my absence. Experience, therefore, of the value of the two soldiers, whom General Darling was good enough to permit me to take on the strength of the party, fully bears me out in recommending that one man, at least, of general responsibility shall be attached to all future expeditions. The success of an expedition depends so much on the conduct of the persons of whom it is composed, that too much attention cannot be given to the selection even of the most subordinate. Men of active intelligent minds, of persevering habits, and of even temper, should be preferred to mechanics who do not possess these most requisite qualities. On the other hand, it is impossible to do without a good carpenter, however defective he may be in other respects. I was indebted to Mr. Maxwell, the superintendent of Wellington Valley, for some excellent men, both on my first and on my second journey, because he understood the nature of the service for which they were required, and the characters of those whom he recommended. But however well selected the party, or the men rather, might be, I still consider a man of general responsibility necessary for its complete organisation. I would have him somewhat superior to the rest in his station in life. Him I would hold answerable for the immediate discipline of the camp, whilst I was present, and for its safety when absent. The assistant to the leader I would put entirely out of the question. He has other and most important duties to perform. I would rate this man wholly independent of him.
