The Surveyor-General had lately returned from an exploring journey to the eastward of the capital, and reported that there existed no reasonable probability of extending the colony in that direction: he strongly recommended us to proceed at once to the north-west coast, and return again to Swan River to recruit; saying that we should find the heat there too great to remain for a longer period. This course Captain Wickham, after due deliberation, resolved to adopt, and accordingly all the stores, not absolutely required, were forthwith landed, and the ship made in every respect as airy as possible. The 25th November was fixed for our departure, when most unfortunately Captain Wickham, while on his way to Perth, was attacked with a severe dysentery, and continued so ill that he could not be brought to the ship till the end of December. The most that could be effected was done to improve this unavoidable delay; and our tidal observations, before commenced, were more diligently pursued. We found the greatest rise only thirty-one inches, and here, as elsewhere on the Australian coast, we observed the remarkable phenomenon of only one tide in the twenty-four hours! Surveying operations were also entered on, connecting Rottnest Island with the mainland; the dangers which surround it, as well as those which lie between its shores and the coast, were discovered and laid down: this survey, of great importance to the interests of shipping in these waters, was ultimately completed on our subsequent visits to Swan River. That arid appearance which first meets the settler on his arrival, and to which allusion has already been made, cannot but prove disheartening to him: particularly if, as is generally the case, his own sanguine expectations of a second Paradise have been heightened by the interested descriptions of land jobbers and emigration agents.
