From the beginning of the Colony of New South Wales the Governors had had authority to make grants of land. Governor Phillip's instructions from the Sovereign, dated 25th April 1787, empowered him to do so "reserving only to us such timber as may be growing or to grow thereafter upon the said land which may be fit for naval purposes". Phillip exercised this authority from time to time: see Historical Records of Australia, series I, vol. 1, pp. 14, 124, 307, 310. Later grants were made with a right reserved by the Crown to take from the land granted timber, sand, clay, gravel and other natural produce required for public purposes: see Campbell v. Dent [1] . A provision of that kind was considered by Smith J. in Bayview Properties Pty. Ltd. v. Attorney-General (Vict.) [1] to be in the nature of a profit à prendre. That case was referred to in the argument before us: but it has no direct bearing on the present problem. A right to sever and take from land things that until severed are part of the freehold is different from a condition of a grant, expressed as a reservation, enabling the resumption of part of the land itself for a specified purpose such as a road. As I have said, reservations for roads began in the time of Governor Macquarie. To advance his policy of providing roads for the Colony he had a new clause inserted in all grants of land. It ran: "and saving and reserving to Government the Right of making a Public Road through such part of the said land as may at any time be required": see Historical Records of Australia, series I, vol. 7, p. 626. This example was followed after Macquarie's time. The form was progressively elaborated, but without any change in the essential character of the right it reserved to the Crown as against the grantee of the land. What was the nature of that right? At one time there was much discussion of it in terms of the distinction between an exception and a reservation. Insisting that each of those terms should keep its proper place has some appeal for those who like to find their law in Coke on Littleton or Shepherd's Touchstone. But since the judgments in Lord v. Commissioners for the City of Sydney [2] , on appeal from the Supreme Court of New South Wales [3] ; and in Cooper v. Stuart in the Privy Council, [4] and in the Supreme Court [5] , it has little weight in cases such as this. Those authorities establish that the reservation of so much of the land granted to Main as might thereafter be required for making public ways was not an exception repugnant to the grant. It was a valid provision. Lord Watson said in the last-mentioned case [6] that "it looks to the future, and possibly to a remote future. It might never come into operation, and when put in force it takes effect in defeasance of the estate previously granted, but not as an exception". It was "retaining the right to resume such parts as may be found necessary for the uses of an increased population" [7] . A reservation of that kind differs from a so-called reservation of a specified area of land. Such a reserve, if it be sufficiently described and defined, is in truth an exception. It does not pass by the grant. In Neild v. Davidson [8] , a case of that kind, Darley C.J. said [1] : "It is called a reservation, but that does not make it less an exception. This exception operates immediately, and the subject matter of it never did pass to the grantee." Attorney-General (N.S.W.) v. Dickson [2] is another illustration. The two kinds of reservations were contrasted by A. H. Simpson C.J. in Eq. in McGrath v. Williams [3] . The reservation in the grant to Main was of the former kind. He got a good title to the whole square mile the subject of the grant, but defeasible as to such parts and so much as the Crown might thereafter require and resume for a road. The way in which the Crown's right of resumption for a road was exerciseable was as stated in the deed. The road was to be "set out by Our Governor for the time being of Our said Territory, or some Person by Him authorised in that respect." The phrase "set out" in relation to roads and highways was well known in 1846. For example, it had been so used in England in the Inclosure (Consolidation) Act, 1801, ss. 8 and 9 and in the Inclosure Act, 1845, s. 62. A road is ordinarily set out by something done on the land to indicate its course and dimensions. To show it on a map may not suffice: Metropolitan Bank Ltd. v. Camberwell Corporation [4] ; Brunswick Corporation v. Baker [5] ; and see Snushall v. Kaikoura County Council [6] and Wellington City Corporation v. McRea [7] . But whether a road was set out by the Crown is a question of fact and an official notification and record such as a statement in the Gazette or the publication of a duly authorized map is conclusive of that fact: see generally as to maps as evidence of the existence and due dedication of highways, Pratt and Mackenzie, Law of Highways, 20th ed., p. 46.
