The roads which were opened by the above means, or proposed to be opened, have become almost impassable, or remain wholly so; and it is, therefore, the less surprising that the colonists look to the possible introduction of railways with much interest. In a country like that around Sydney, where extensive tracts of inferior land must be traversed by roads in order to arrive at lands which are productive and settled, the value and importance of a railway would be greatly enhanced; and calculations have been made to show that a railway between Sydney and the southern districts would pay, even from the traffic at present along that line. The town of Goulburn, 124 miles from Sydney, in an open undulating country, at a considerable height above the sea, is rapidly growing into importance; and, by making either a good road or a railway, between that town and Sydney, access would be gained to very extensive tracts of valuable territory, easily traversed, and to which Goulburn is a sort of centre. On the whole, it may be said that the difficulty of access to the best lands, from the want of good roads to them from the principal port, has, of late years, greatly impeded the introduction of immigrants to the rural districts, and added to the population of Sydney many individuals who had been brought to the colony at the public expense, for the assistance of settlers in the country. CONCLUSION. The employment of convicts on useful public works was, twenty years ago, a primary object with the government of New South Wales. The location of settlers on their grants by the measurement of their farms, then much in arrear, and the division of the territory into counties, hundreds, and parishes, in order to complete the deeds of grant to settlers, altogether rendered necessary a general survey of the colony, which work I commenced in 1827, EX OFFICIO, and, pursuant to Royal Instructions, sent to the colony in 1825. The time between the years 1827 and 1837 was the most prosperous in the history of the colony of New South Wales, when convicts made good roads, farms were measured up, and the country was surveyed and divided into countries. Colonization extended rapidly to the shores of the southern ocean, and Australia Felix was made known to the British public.
