Under the most favourable circumstances, it was improbable that the men would be enabled to pull for many days longer in succession; since they had not rested upon their oars for a single day, if I except our passage across the lake, from the moment when we started from the depot; nor was it possible for me to buoy them up with the hope even of a momentary cessation from labour. We had calculated the time to which our supply of provisions would last under the most favourable circumstances, and it was only in the event of our pulling up against the current, day after day, the same distance we had compassed with the current in our favour, that we could hope they would last us as long as we continued in the Murray. But in the event of floods, or any unforeseen delay, in was impossible to calculate at what moment we might be driven to extremity. Independent of these casualties, there were other circumstances of peril to be taken into consideration. As I have already observed, I foresaw great danger in again running through the natives. I had every reason to believe that many of the tribes with which we had communicated on apparently friendly terms, regretted having allowed us to pass unmolested; nor was I at all satisfied as to the treatment we might receive from them, when unattended by the envoys who had once or twice controlled their fury. Our best security, therefore, against the attacks of the natives was celerity of movement; and the men themselves seemed to be perfectly aware of the consequences of delay. Our provisions, moreover, being calculated to last to a certain point only, the slightest accident, the staving-in of the boat, or the rise of the river, would inevitably be attended with calamity. To think of reducing our rations of only three quarters of a pound of flour per diem, was out of the question, or to hope that the men, with less sustenance than that, would perform the work necessary to ensure their safety, would have been unreasonable. It was better that our provisions should hold out to a place from which we might abandon the boat with some prospect of reaching by an effort a stock station, or the plain on which Robert Harris was to await our return, than that they should be consumed before the half of our homeward journey should be accomplished. Delay, therefore, under our circumstances, would have been imprudent and unjustifiable.
