The construction of the deed from the demandant’s ancestor to the town of Uxbridge is not free from difficulty; but upon careful consideration we are of opinion that, adhering in its interpretation, as we are bound to do, to the strict rules of the common law respecting grants of real property, we cannot construe it as a deed upon condition.
It is said in Shep. Touchstone, 126, that “ to every good condition is required an external form; ” that is, it must be expressed in apt and sufficient words, which according to the rules of law make a condition; otherwise it must fail of effect. This is especially the rule applicable to the construction of grants. A deed will not be construed to create an estate on condition, unless language is used which, according to the rules of law, ex proprio vigore, imports a condition, or the intent of *128the grantor to make a conditional estate is otherwise clearly and unequivocally indicated. Conditions subsequent are not favored in law. If it be doubtful whether a clause in a deed be a covenant or a condition, courts of law will always incline against the latter construction. Conditions are not to be raised readily by inference or argument. Co. Litt. 205 b, 219 b. 4 Kent Com. (6th ed.) 129, 132. Shep. Touchstone, 133. Merrifleld v. Cobleigh, 4 Cush. 178, 184.
In the deed on which the present controversy arises there are, strictly speaking, no words of condition, such as of themselves import the creation of a conditional estate. The usual and proper technical words by which such an estate is granted by deed are, “ provided,” “ so as ” or “ on condition.” Lord Coke says, “ Words of condition are sub conditione, ita quad, proviso.” Mary Portington’s case, 10 Co. 42 a. Co. Litt. 203 a, 203 b. So a condition in a deed may be created by the use of the words “ si,” or “ quad si contingat,” and the like, if a clause of forfeiture or reentry be added. Co. Litt. 204 a, 204 b. Duke of Norfolk’s case, Dyer, 138 b. 1 Wood on Conveyancing, 290. In grants from the crown and in devises, a conditional estate may be created by the use of words which declare that it is given or devised for a certain purpose, or with a particular intention, or on payment of a certain sum. But this rule is applicable only to those grants or gifts which are purely voluntary, and where there is no other consideration moving the grantor or donor besides the purpose for which the estate is declared to be created. But such words do not make a condition when used in deeds of private persons. If one makes a feoffment in fee ea intentione, ad ejfectum,, ad propositum, and the like, the estate is not conditional, but absolute, notwithstanding. Co. Litt. 204 a. Dyer, ubi supra. 1 Wood on Conveyancing, 290. Shep. Touchstone, 123. These words must be conjoined in a deed with others giving a right to reenter or declaring a forfeiture in a specified contingency, or the grant will not be deemed to be conditional. It is sometimes said that the words “ causa” and “ pro,” when used in deeds, create a condition ; that is, where a deed is made in express terms for a specific purpose, or in *129consideration of an act to be done or service rendered, it will be interpreted as creating a conditional estate. But this is an exception to the general rule, and is confined to cases where the subject matter of the grant is in its nature executory; as of an annuity to be paid for service to be rendered or a right or privilege to be enjoyed; in such case if the service be not performed or the enjoyment of the right or privilege be withheld which formed the consideration of a grant, the grantor will be relieved from the further, execution of the grant, to wit, the payment of the annuity. Shep. Touchstone, 124. Cowper v. Andrews, Hob. 41. Co. Litt. 204 a. But ordinarily the failure of the consideration of a grant of land, or the non-fulfilment of the purpose for which a conveyance by deed is made, will not of itself defeat an estate. The reason for this distinction between the two classes of cases is, as stated by Coke, “that the state of the land is executed and the annuity executory.” Co. Litt. 204 a. There is one other class of grants which are sometimes said' to be conditional; as when a feoffment is made ad solvendum, “ for the matter shows that the intent of the feoffor was to have the land or the money; ” or a grant ad erudiendim Jilium, “ because the words purport that the instruction is to be given, or the feoffment will be void.” It may be doubtful whether such words do operate in strictness as a condition. The latter case is stated in the Touchstone doubtfully, in this wise: “ Some have said this estate is conditional.” But if grants so expressed can be construed to create a condition by which to defeat an estate on breach and entry, it is clear that such an interpretation of them is confined to cases where the whole consideration of the grant is the accomplishment of a specific purpose, and the enjoyment of the estate granted is clearly made dependent on the performance of an act or the payment of money for the use or benefit of the grantor or his assigns. We believe there is no authoritative sanction for the doctrine that a deed is to be construed as a grant on a condition subsequent solely for the reason that it contains a clause declaring the purpose for which it is intended the granted premises shall be used, where such purpose will not enure specially to the benefit of the grantor and *130his assigns, but is in its nature general and .public, and where there are no other words indicating an intent that the grant is to be void if the declared purpose is not fulfilled.
If it be asked whether the law will give any force to the words in a deed which declare that the grant is made for a specific purpose or to accomplish a particular object, the answer is, that they may, if properly expressed, create a confidence or trust, or amount to a covenant or agreement on the part of the grantee. Thus it is said in The Duke of Norfolk's case, Dyer, 138 b, that the words “ ea intentione ” do not make a condition but a confidence and trust. See also Parish v. Whitney, 3 Gray, 516, and Newell v. Hill, 2 Met. 180, and cases cited. But whether this be so or not, the absence of any right or remedy in favor of the grantor under such a grant to enforce the appropriation of land to the specific purpose for which it was conveyed, will not of itself make that a condition which is not so framed as to warrant in ^law that interpretation. An estate cannot be made defeasible on a condition subsequent by construction founded on an argument ab inconvenienti only, or on considerations of supposed hardship or want of equity.
In the light of these principles and authorities we cannot interpret the words in the deed of the demandant’s ancestor, which declare that the premises were conveyed “ for a burying-place forever,” to be words of strict condition. Nor can we gather from them that they were so intended by the grantor. The grant was not purely voluntary. It was only partially so. It was not made solely in consideration of the love and affection which the grantor bore towards the grantees, but also “ for diverse other valueable considerations me moveing hereunto.” Previously to the time of the grant, the premises had been used for a burial-place. It is so described in the deed. Under what circumstances this had been done does not appear. It may have been for a compensation. We cannot now know, therefore, that the sole cause or consideration which induced the grantor to convey the estate to the town was, that it should be used for the specific purpose designated in the deed. There can be no doubt of the intent of the grantor that the estate *131should always be used and appropriated for such purpose. This intent is clearly manifested; but we search in vain for any words which indicate an intention that if the grantees omitted so to use them, and actually devoted them to another purpose, the whole estate should thereupon be forfeited, and revert to the heirs of the grantor. The words in the deed are quite as consistent with an intent by the grantor to repose a trust and confidence in the inhabitants of the town, for whom he declared his affection and love, that they would always fulfil the purpose for which the grant was made, so long as it was reasonable and practicable so to do, as they are with an intent to impose on them a condition which should compel them, on pain of forfeiture, to maintain the premises as a burial-place for all time, however inconvenient or impracticable it might become to make such an appropriation of them. Language so equivocal cannot be construed as a condition subsequent without disregarding that cardinal principle of real property already referred to, that conditions subsequent which defeat an estate are not to be favored or raised by inference or implication.
Judgment for the tenants.
