The opinion of the court was delivered by_

It seems that in May, 1888, the plaintiff sold and delivered to the intestate, L. A. Mills, of Spartanburg, six Jersey heifers for $525. The plaintiff claimed that the contract (which was verbal) was cash on delivery; but some contention arose as to the blood, and especially as to the “registry” of the animals. In 1885 L. A. Mills died, and O. P. Mills *57becoming the administrator of bis estate, was sued by the plaintiff upon the contract in February, 1887. The complaint was simply for the purchase money, $5:15, without any mention of interest. The defendant answered that, as informed, his intestate did agree to purchase certain calves from the plaintiff, and that the plaintiff promised to give him a written guarantee and have the animals “registered” before they were paid for, which he, the plaintiff, would not or could not do; that upon this discovery, his intestate offered to return the cattle, upon being paid his expenses, which offer was refused ; and that plaintiff failed to keep his contract to the damage of the intestate $500.

The plaintiff proved that he had the heifers “registered” in “The American Jersey Herd Register” kept at Worcester, Mass. S. Harris, the only person except the parties themselves, who was present when the contract was made, testified “that he was present when the contract was made between plaintiff and intestate : four of the heifers were about 14 months old, two about 3 months old. They were very poor at the time. The understanding was that they were to be ‘registered,’ or certificate forwarded to that effect. Don’t know if book was mentioned in which they were to be ‘registered.’ It was not to his knowledge. I am a Jersey cattle man to a small extent; not an expert in ‘registering,’ &c. ‘The American Jersey Cattle Club Herd Registry’ is the only registration ‘Book’ in this country for Jersey cattle. The cattle registered in the book spoken of by Mr. Burns (American Jersey Herd Registry) were worth no more than grades or any other cattle,” &c. It was satisfactorily proved that “The American Jersey Cattle Club Herd Registry” was the only recognized registration book in this country for Jersey cattle, and that the heifers sold to the intestate Mills were not registered therein.

Under the charge of the judge, the jury found for the plaintiff the full amount of the account and interest, $705.66. Thereupon the plaintiff moved for leave to amend the complaint, so as to include a count for interest, -which was refused. The defendant then moved for a new trial on the minutes, which was also refused, and the defendant appeals, alleging error as follows:

“1. In charging that if there was a contract between plaintiff *58and intestate, and the contract is proved, they should find for the plaintiff with interest.

“2. In refusing the motion for a new trial.

“3. In not at least granting a new trial nisi, the plaintiff remitting all of the verdict over $525, demanded in the complaint.

“4. In giving $5 costs against the defendant in refusing a motion for a new trial.

“5. In charging the jury that if they concluded that the contract between plaintiff and intestate was, that there was to be a registration of the cattle, then the contract, being a verbal one, was for their interpretation.

“6. In charging that the law in regard to a verbal contract is not what Mr. Mills intended by the contract, but if Mr. Burns made an offer to,Mr. Mills and Mr. Mills accepted it, it is what Mr. Burns, intended Mr. Mills should understand by his promise that these should be ‘registered’ cattle.

“7. In charging that it was what plaintiff offered to do, and what he intended that intestate should understand that he offered ■to do. that should govern.

“8. In charging that the above definition should only help the jury, if they should conclude that registration had not been sufficiently ^defined to them by persons sufficiently competent to know.

“9. In charging that it might be that the jury sufficiently understood the technical word ‘registered,’ when applied to Jersey cattle, to give it a definite fixed meaning, and it was for them to say whether that definite fixed meaning was used by Mr. Burns when he guaranteed it.

“10. In charging the jury that it might be that registration in. one of the registration books would be as good as the other.

“11. In charging that if the jury should come to the conclusion that Mr. Mills with full knowledge of the facts, accepted these cattle, whether they were registered or unregistered, would make no difference.” ' .

Exceptions 5, 6, .7, 8, and 9 substantially allege error in the charge, “That the law in regard to a verbal contract is not what Mr: Mills intended by the contract, but if Mr. Burns made an offer to Mr. Mills, which he accepted, it is what Burns intended Mills should understand by his promise that these should be reg*59istered cattle.” We are not quite sure that we apprehend this clearly as applied to the facts of this case. If there had been nothing ambiguous in the terms used; if there had been a certain fixed meaning universally attached to the term “registered,’.’ then the proposition would have been entirely unobjectionable; for a distinct offer made in unequivocal terms and accepted, is the very definition of an agreement.. But as we understand, such was not the case here. It was undoubtedly a part of the contract that the heifers should be “registered,” whatever that may be; that is shown net only by the proof, but by the nature of the conr tract itself, for it can hardly be supposed that any man would agree to give $525 for six calves in bad condition, two of which were not more than three months old, unless there was something connected with them which gave or was supposed to give them unusual value. The intestate wished to breed Jersey cattle for the market, and it is clear that, the promised registration as to him was an essential part of the consideration, as affording record evidence of the pure breed of the stock.

It seems, however, that there were two books of registry : one (A. J. C. 0.) which afforded the best evidence of the purity of the stock registered, and generally regarded in this country as the only proper registry of Jersey cattle, and the other (A. J. 0. IT.) much less valuable in that respect. The contract did not specify which “registry” was meant; and the confusion has arisen from the fact that the term used, “registered,” admits of more than one sense ; and that being the case, it seems to us that it was error to say that the contract should be interpreted by what was the intention of Burns, the seller, without any regard to the concurring intention of the intestate, the purchaser. It strikes us that the term used, being capable of two meanings, it was not enough to consider alone the intention of Burns. It was incumbent upon the plaintiff to make out the special contract upon which he sued. He proved that he had “registered” the cattle in the registry, which was not the approved and accepted registry of the country. There was no proof that the intestate meant that registry. “The most essential element of an agreement is the consent of the parties. If two or more parties express their consent to a common purpose, this is an. agreement. *60The terms of a proposal must be sufficiently certain to enable the court to say what the agreement is.” 3 Am. &Eng. Encycl. Law, 841. An agreement to be binding must be understood and assented to by both parties. It is elementary that, in order to constitute a binding contract, there must.be a definite promise by the party charged, accepted by the person claiming the benefit of such promise. Chit. Con., 9. It takes two to make a binding bargain, and where the terms used are equivocal, both parties must assent in the same sense. The minds of the parties must meet (Gary v. Watson, 16 S. C., 623), as was strongly illustrated by.the old case put by Dr. Paley in his chapter on “promises,” where a commander offered to receive the surrender of a garrison without bloodshed, and then buried them alive.

This makes it unnecessary to consider the other exceptions.

The judgment of this court is, that the judgment of the Circuit Court be reversed, and the case remanded for a new trial.
