This is an action which was brought upon the following subscription paper:
“In consideration of value received and for the purposes hereinafter expressed, within thirty days after demand, we who subscribed our names hereto promise to pay to William MeClanahan, Warren McCullough, Theo.

*289One of tbe defenses pleaded by tbe answer of tbe defendants was that they subscribed tbe said subscription - contract upon the express agreement with the plaintiffs that-their subscriptions should not be binding and should not be delivered nor accepted until there was ten subscribers thereto, including themselves, for the sum of five hundred dollars each; that while said subscription contract was in the hands of one Winters, who was then soliciting subscribers and subscriptions thereto, and before the same had been delivered to. plaintiffs, and before they had expended any money or incurred any liability in promoting the subscription enterprise, defendants notified and informed the said Winters and the plaintiffs that they withdrew their said subscription and would not pay the- same. At the trial, these allegations of the defendants’ answer were fully sustained by the evidence.
The cause was tried by the court without the aid of a jury. Its finding and judgment was for defendants. It has been repeatedly ruled by the appellate courts of this state that when a case is submitted to the court without the aid of a jury its finding is conclusive if there is any substantial evidence on which to base it. Caruthers v. Williams, 58 Mo. App. 100; Arnold v. Ins. Co., 55 Mo. App. 149; Smith v. Zimmerman, 51 Mo. App. 519; Swayze v. Bride, 34 Mo. App. 414; Gaines v. Fender, 82 Mo. 491; Hamilton v. Boggess, 63 Mo. 233.
But the plaintiffs here insist that the defense pleaded by the answer, and to which we have just referred, was invalid — no defense whatever. The subscription made by the defendants was a gratuitous one. In Beach on Contracts, section 206, it is said: “A gratuitous subscription is a mere offer which may be revoked at any time before it is accepted by the promisee. And on acceptance can only be shown by *290some act on the part of tbe promisee whereby some legal liability is incurred or money is expended on the faith of the promise.”
In 1 Parsons on Contracts, section 450, it is stated: “The party making the promise is bound to nothing until the promisee within a reasonable time engages to do, or else does or begins to do, the thing which is the condition of the first promise. Until such engagement or such doing, the promisor may withdraw his promise, because there is no mutuality, and therefore no consideration for it. But after an engagement on the part of the promisee which is sufficient to bind him, then the promisor is bound-also, because there is now a promise for a promise, with entire mutuality of obligation.”
Where notes are given by way of voluntary subscription to raise a fund or promote an object, they are open to the defense of want of consideration unless money has been expended, or liabilities incurred which, by legal necessity, must cause loss or injury to the person so expending money or incurring liability if the notes are not paid. 1 Parsons on B. & N., p. 202; 1 Parsons on Confer., 377 et seq. The promise stands as a mere offer, and may by necessary consequence be revoked at any time before it is acted upon. It is the- expending money, etc., or the incurring of legal liability on the faith of the promise which gives the right of action. The subscription is a mere offer until acted upon, because until then there is no mutuality. Being but an offer, it is susceptible of revocation at any time until it is acted upon. This seems to be the clear result of the adjudicated cases. Pratt v. Trustees, 93 Ill. 475; McCune v. Wilson, 43 Ill. 356; Richilieu v. Encampment, 140 Ill. 248; Beach v. Church, 96 Ill. 177; Williams v. Rogan, 59 Texas 438, and cases there cited; La Fayette Co. v. Magoon, 73 Wis. 627; *291Grand Lodge v. Farnham, 70 Cal. 158; Church v. Kendall, 121 Mass. 528; Lapsley v. Howard, 119 Mo. 489; Egger v. Nesbitt, 122 Mo. 668; Workman v. Campbell, 46 Mo. 305; Corrigan v. Detsch, 61 Mo. 290.
Similar promises of others to plaintiffs may be a consideration for agreements, between such others and plaintiffs, but as they confer no benefit upon defendants and impose no charge or obligation upon plaintiffs they constitute no legal consideration for defendants’ promise. Church v. Kendall, ante; Orphans’ Home v. Sharp, 6 Mo. App. 150. The rule that denies to a subscriber the right to revoke his subscription when others have subscribed on the faith of his subscription has no application in a case like this where the subscription contract does not provide for raising any specific amount. Kelly v. Oliver, 113 N. C. 442.
When the defendants recalled their promise to pay the five hundred dollars, the subscription paper evidencing it was still in the hands of Winters, a solicitor who had been appointed at a citizens’ meeting, and perhaps by the trustees, to procure subscriptions for the object named in the subscription paper. It had not been reported to, nor accepted by either a citizens’ meeting or by the plaintiffs in their capacity of trustees. At that time it remained to be ascertained whether the amount that would probably be necessary to accomplish the object could be raised, so that it is quite evident the trustees as prudent business men, as they no doubt were, had not up to that time incurred any liability on that account. Before doing so they would of course wait until the subscriptions were turned over to them. It may be that they in advance of the return of the subscriptions took options on such real estate as they thought desirable to acquire in order to carry out the subscription object in case the necessary amount should later on be subscribed for .that purpose, but it *292can not be said that they thereby incurred any liability on the faith of such subscriptions. No reason is seen Why the defendants, at the time they notified Winters of the recall of their subscriptions, did not have the legal right to do so. There was then no irrevocable binding promise to pay the amount subscribed. The subscription was yet no more than a voluntary offer — something like the offer of a reward— which had not yet ripened into a contract. It was yet subject to recall, or modification. Defendants could then, no doubt, have increased or diminished it, or have hampered its payment with named conditions had they seen fit to do so. It was no more binding on them then than it was the moment they signed it. Their relation as promisors and that of the trustees as promisees were exactly the same as they were when the subscription paper was signed, and consequently they had the right to recall it.
It is objected by plaintiffs that the court erred in rejecting an offer of evidence' made by them to show a ratification of the subscription, but on turning to the pleadings it is there seen that to the defense pleaded by answer, the plaintiffs in reply did not plead either a ratification nor estoppel; and therefore the court did not err in rejecting their said offer. The rule is well settled that a party can not have the benefit of either a ratification or an estoppel unless it has been pleaded by him. Webb v. Allington, 27 Mo. App. 559; Ferneau v. Whitford, 39 Mo. App. 311.
It is further contended that the notice of withdrawal which the défendants gave to Winters was ineffectual.
In this we do not concur for the reason that it is conceded that Winters was the agent of both the trustees and those engaged in promoting the object named in the subscription papers. Any notice to Winters in respect to the subscriptions which he was soliciting or which had been *293obtained but b.ad mat been accepted was notice to his principals. It was his duty when returning the subscriptions to inform his principals of the fact that the defendants had revoked their subscription. It must be conclusively presumed that he performed this duty so far as defendants are concerned. The evidence tends to show that the trustees were otherwise sufficiently advised of the defendants’ withdrawal before they accepted the subscription papers or incurred any liability on the faith thereof.
The defense already referred to was fatal to the plaintiffs’ claim and whether or not the other defense pleaded in the defendants’ answer was valid or invalid, or whether the theories embodied in plaintiffs’ refused instructions were or were not correct expressions of the law it is unnecessary for us to inquire, since the judgment of the court was for the right party'and was the only judgment that it could have given. Accordingly, it will be affirmed.
All concur.
