The last service rendered by Walker, the explorer, was in connection with the selection of the route of the telegraph line from Cardwell to the Gulf of Carpentaria. Mr. Walker's second in command was a fine young man of the name of Herbert Edward Young, who was subsequently telegraph master in Townsville in the year 1871. Mr. Young received an injury in the service which eventually resulted in his untimely death very shortly after his marriage. Australia was connected with Europe by cable in 1872. Queensland thus starting on its career so hopefully was nevertheless subject to periods of depression, booms, and crises, prosperity and hard times alternated. And then came the "salvation by gold." The discovery of gold came as a hope and help to all, as it came to the North a few years later. It helped to find markets for stock of all kinds and employment for thousands, and also to extend the settlement of the land and open up commerce with other countries, introducing immigrants or diggers, many of whom remained and settled in the country. But the young country had to be opened up and some degree of settlement established before mining for gold could be carried on. In all parts of Queensland, pastoral settlement has preceded all others, including mining. Though the squatter is now, in the more settled districts, becoming a thing of the past, his work being finished and his day gone by, at the first enterprise, bush knowledge and a practical life were the most potent factors in making known the possibilities of the land of Queensland. The name "squatter" was given in the early days to the pastoral tenants of the Crown, who rented pasture lands in their natural state. The first pastoral occupation took place about 1840, and this may be said to have commenced the life history of the movement that made Queensland known to the world. Large areas were occupied on the banks of rivers and creeks where the splendid and nutritive indigenous grasses required no further cultivation. All that the squatters did was to turn their stock loose on them and exercise some care to prevent them from straying, or being killed and scattered by the blacks. No country was ever endowed by Nature with a more permanent, healthy, and beneficial pasturage than Australia, though heavy stocking and hot dry seasons have somewhat diminished the value of this natural wealth in some of the earlier settled districts. The chief source of employment in the Colony of Queensland, and the leading export, is still derived from the stock depastured on the native grasses that were found when the State was first explored.
