Opinion by
Mr. Chief Justice Moschzisker,In this equitable proceeding to obtain a conveyance of four tracts of land described in a written agreement between tbe parties to tbe suit, tbe court below, sustaining a demurrer, beld the contract so indefinite regarding tbe property to be conveyed as to prevent a decree of specific performance against defendants; plaintiffs have appealed.
Tbe particular provision wbicb gives rise to tbe controversy is as follows: “Tbe premises are to be conveyed clear of all encumbrances or easements or other obligations to tbe title except a life interest to be excepted and reserved by tbe parties of tbe first part [vendors in tbe agreement, and defendants here] in the bouse wbicb they now occupy and one-balf acre of tillable ground for raising garden truck, wbicb plot of ground will be later designated by tbe parties hereto.”
In sustaining tbe demurrer, tbe court said: “It is apparent tbe one-balf acre so to be excepted from tbe four tracts of land has never been designated or located by tbe parties to tbe contract. Neither is there any averment that plaintiffs have requested defendants to agree upon tbe location thereof, nor that plaintiffs, before tbe filing of their bill of complaint, offered to accept such location of tbe reservation as defendants might designate. Looking only at plaintiffs’ bill, it does not appear that either plaintiffs or defendants have made any attempt to agree upon a location of this reservation, although tbe contract specifically states that such reservation ‘will be later designated by the parties hereto.’ In other words, as tbe case now stands, both parties have neglected to designate, or to attempt to designate, tbe location of tbe reservation, [and] without such location......it would be impossible to execute and deliver a deed in accordance with tbe terms of tbe contract.......‘A chancellor can only enforce an agreement specifically where tbe parties have agreed definitely on all *326its terms and left nothing to the future but mere performance’ : Agnew v. Southern A. L. Co., 204 Pa. 192.” In this we see no error.-
While here the uncertainty of description concerns what is reserved out of the tracts of land to be conveyed, it is, nevertheless, apparent that if, from a definite whole, an indefinite part is excepted, necessarily the remainder is rendered so uncertain that it is impossible to order a conveyance till the indefinite part is ascertained.
In the case of Agnew v. Southern, supra, it was provided by the contract in suit that the size of the lot of ground purchased was to be determined thereafter, referring to a general plan “to be laid out and established.” Mr. Justice Mitchell said, affirming a decree dismissing the bill: “The memorandum in writing on which appellant’s bill is founded is......wanting in that complete and definite character which is necessary to enable a court of equity to decree specific performance. The bill supplements the memorandum by describing the land as Tot No. 1, in a plan......’ It may be conceded that if the memorandum itself had so described it, the court might have resorted to extrinsic evidence......to identify the subject-matter......The memorandum itself [however] not only fails to identify the land in question ......, but shows affirmatively that the precise...... location and boundaries of the intended purchase were left to future......determination......The definite terms of the contract were thus expressly left for the future actions of the parties......A chancellor can only enforce an agreement specifically where the parties have agreed definitely on all its terms and left nothing to the future but bare performance.” This language well applies to the case at bar.
In the instant case there is to be “excepted and reserved” from the deed of conveyance a life estate by the vendors (defendants) “in the house which they now occupy,” and the same estate in “one-half acre of tillable ground,” it being expressly provided by the contract *327that this “plot of ground will be later designated by the parties hereto.” The parties having thus expressly agreed how the portion reserved out of the conveyance should be determined and “designated,” neither the separate selection of the vendors or vendees nor the judgment of the chancellor can be substituted without making a new contract for them. Perhaps the “house which they [the vendors] now occupy” might be located by parol (O’Connell v. Cease, 267 Pa. 288), on the theory of locating a subject-matter sufficiently described to satisfy the statute of frauds, but not so the half-acre of ground, the designation of which was expressly left to future joint action of the parties.
Under the express terms of the present agreement, the reservation is so connected with acts yet to be performed by the contracting parties, in order to determine and adequately describe the property involved, that there can be no application of the rule which appellants claim should control this case, namely, “If the description of the exception is void for uncertainty, the title for the whole tract passes......(8 R. C. L. 1097; 18 Corp. Juris 344, 348).” As correctly said in the work last above cited (18 C. J. 348), uncertainty of description does not render a reservation void where there is a method provided in the deed “whereby it can be made sufficiently certain.”
Finally, we cannot hold, as appellants would have us do, that “it was the intention of the parties to reserve the right to designate the one-half acre of ground after the delivery of the deed”; the plain words of their contract, quoted at the beginning of this opinion, forbid such construction.
We have examined the numerous authorities cited; those controlling us are not at variance with the views here expressed, nor with the ultimate conclusion reached by the court below, and those from other jurisdictions are distinguishable on their facts.
The assignments of error are overruled and the decree is affirmed at cost of appellants.
