The court adhere to the opinion pronounced in the case of Seventeenth-street, (1 Wendell, 262,) that in the city of New-York the fee of the land comprised in the space called a street, previous to its being opened by the corporation, does not pass to the purchasers of the- lots hounded upon it, as it would do were the lots bounded on a public highway out of the limits of the city; but that it remains in the grantor, the owners of the lots having a perpetual right of way over the space called a street. *474The case of Seventeenth-street was distinguished from that of Mercer-street, (4 Cowen, 542,) inasmuch as the purchasers in the former case had no access to their lots from any public way but by the space called a street in their deeds ; whereas in the latter case they had access from Broadway, and there was no necessity of using the space called a street. These cases were therefore supposed not to conflict with each other. The facts of the case now under consideration are precisely the same in principle as those in the case of Mercer- ■ street, as it respects the lots bounding upon the streets intersecting Lewis-street. The commissioners of estimate and assessment, instead of adopting the rule laid down in that case as it regards those lots, have made their assessment as to all the lots in conformity to the principles established by the court in the case of Seventeenth-street; and on a review of the case of Mercer-street, and a more mature consideration of the subject, the court have come to the conclusion that the case of Mercer-street was incorrectly decided, and confirm the report made in this case by the commissioners, who have allowed a compensation to the owners of the land only for the fee, (which, on the street being opened, vests in the corporation,) considering the purchasers of the lots as entitled to the easement or right of way, and that consequently the owner was not entitled to the full value of the land.
The principal part, if not the whole of the island of N. York, is laid out into avenues and streets, and so designated on a map of the city, although not actually opened. Purchases are made of lots for the purpose of erecting buildings thereon, and not for agricultural or horticultural uses ; and when a purchase is made of a lot bounding upon a street in the city of New-York which is not yet opened, the purchaser is entitled to all the'benefits and advantages belonging to the property of which he has become the owner; one of the most essential of which is, that when the street is opened, upon the application of the corporation conformably to the law regulating streets in that city, he will have a lot fronting upon a street upon which a building may be erected, without being subject to an assessment to compensate the owner of the fee to the full value of the land thus appropriated, the presump*475tian being that the purchaser of the lot paid an enhanced price for the same in consideration of the lot being bounded on a street. The owner is entitled to an allowance, because by the opening of the street the fee is transferred to the corporation; (2 R. L. 414;) but such allowance for the fee should only be nominal, as the easement or right of way belongs to the purchasers of the lots. The purchasers of such lots are subject to the charge allowed as a compensation to the owner for the fee of the street, as standing in the place of the corporation, being thus substituted because more immediately benefitted by the transfer than the owners of property in more distant parts of the city. The court are therefore of opinion that when a building lot is sold, bounded on a street in the city of New-York, designated as such upon the map of the city, or on a map made.by the owner of lands in reference to which sales are made, although the street remains at the time unopened under the authority of the corporation, a covenant may well be implied that the purchaser shall have an easement or right of way in the street to the full extent of its dimensions, and that when the same is subsequently opened, on the application of the corporation, the purchaser is not liable to pay the owner for the value of the land thus appropriated, but only for the fee subject to the easement.
