It has been mentioned that the Alienation of Crown Lands Act of 1860 provided for granting to any immigrant who had paid his passage-money, or to any other person by whom it had been paid, an L18 land order on arrival, and a further land order for L12 after he had resided two years in the colony. These land orders were made receivable as cash at any Crown land sale, and they led to a large traffic, as the fact that land orders could be bought from immigrants at a discount stimulated the demand for land, especially for town lots. At first these instruments could be bought at very low prices, but after a time the L18 land order had become of the recognised market value of L15 to L16 cash, and could be readily purchased at those prices from agents in Queen-street, Brisbane. But the effect upon land sales revenue alarmed the Government, and after a time they refused to receive land orders as payment in lieu of cash at sales of other than country land. In 1864 an Immigration Act was passed providing for the appointment of an Agent-General for Emigration in London, and for the repeal of the land-order sections of the 1860 Land Act. A new provision was made by which the Agent-General was empowered to issue to an approved passenger in London who had paid his passage-money a land-order warrant for L30. On arrival in the colony the passenger was granted in exchange for the warrant a non-transferable land order receivable as cash at face value at sales of suburban and country lands only. These restrictions lowered the market price of the instrument, although by means of a power of attorney the non-transferable provision was for a time evaded. Eventually, however, the restrictions were made so severe that for market purposes the land order was worth little, and immigrants who had come out and failed to settle on the land found themselves in possession of a document of no practicable value. The extent to which the land-order traffic prevailed will be understood when it is mentioned that, in 1865, of L218,431, the total revenue from land sales, only L59,461 was cash, the remainder being represented by land orders. By 1875 the system had become discredited, and was abolished by legislation, but outstanding land orders were still used. In 1883-4 the amount so received had fallen to L16, while the cash receipts for sales were L378,637. The total value of land orders received as cash between 1861 and 1883-4 was L853,583. Some public men have contended that, if the initial practice of receiving the land order at face value in payment for any Crown land sold at auction had been continued, the Treasury would have been recouped by the larger demand and higher prices realised, but obviously a system which stimulated speculation in land was not good for the country, besides which it encouraged dummying. In 1886 the Griffith Government determined to give the system a further trial, and in the Crown Lands
