#5. Governor Robe.#--In 1841 Governor Grey had been of the greatest service to the colony in changing the state of its prospects, but he was not permitted to see more than the commencement of its great prosperity; for, in 1845, he was sent to govern New Zealand, where troubles had arisen similar to those which he had helped to cure in South Australia. His place was filled by Colonel Robe, a military gentleman, of what is called the old school, honourable and upright, but inclined to think that everything ought always to be as it has been. He disliked all innovation, and did what he could to prevent it, much to the discontent of the young and thriving colony, which was of necessity the scene of constant and rapid changes. He passed a very troublous time for three years, and in 1848 was heartily glad to be recalled. #6. Governor Young.#--The colony was then placed under the care of Sir Henry Young, whose policy was completely the reverse. He sought by every means in his power to encourage the ceaseless activity of the people. His failing was, perhaps, an injudicious zeal for progress. For instance, in his desire to open up the river Murray to navigation, he wasted large sums of money in schemes that proved altogether useless. He made an effort to remove the bar at the mouth of the river, but fresh deposits of sand were constantly being brought down by the current, and lashed up into a new bar by the waves that rolled ceaselessly in from the Southern Ocean. He spent about L20,000 in trying to construct a harbour called Port Elliot, near the entrance to the Murray; but there are now only a few surf-beaten stones to indicate the scene of his fruitless attempt. He offered a bonus of L4,000 to the first person who should ascend the Murray in an iron steamer as far as the river Darling. A gentleman called Cadell made the effort, and succeeded; he obtained the reward, but it was not enough to pay his heavy expenses, and when he endeavoured afterwards to carry on a trade, by transporting wool to the sea in flat-bottomed steamers, he found that the traffic on the river was not sufficiently great to repay his heavy outlay, and in a short time he was almost ruined. The attempt was premature; and though, in our time, the navigation of the Murray is successfully carried on, and is, undoubtedly, of immense advantage not only to South Australia, but also to New South Wales and Victoria, yet, at the time when the first efforts were made, it led to nothing but loss, if not ruin to the pioneers.
