The opinion of the Court was delivered by

Plaintiff was landlord and- defendant was a share cropper on his land for the year 1917. They made a verbal contract at the beginning of the year; but, in the fall, a dispute arose between them as to the division of the cotton seed. Plaintiff contended that, by the agreement, he was to have all the seed, while defendant contended that he was to get only half of them; and, when the first bale was sold, defendant kept, half the proceeds of the seed from it. They agreed to settle the controversy by Newton’s bringing an action in the Court of a magistrate against Bennett for half of the proceeds of the sale of the seed from the first bale, which had been retained by him, and allowing the result of that action to determine the issue between them as to the division of -the seed from the remainder of the crop. Thereupon plaintiff brought this action, alleging that defendant had sold the seed from one bale of cotton, which was his property, and refused to pay him one-half of the proceeds of sale, which was $15.33, and demanded judgment for that sum. Defendant denied the allegations of the complaint, except as to the sale of the seed, the price obtained, and his refusal *4 to pay plaintiff one-half thereof; and, for a second defense, he alleged a share crop contract with plaintiff, whereby plaintiff was to furnish the land and fertilizer, and he was to furnish the labor to make the crop, and was to get for his labor one-half of all crops made, including one-half of the cotton seed. He alleged also that plaintiff violated his contract,. in that he failed to furnish the stipulated quantity and quality of fertilizer, and thereby caused a reduction in the yield, and, therefore, his labor was reasonably worth one-half of all the crops made; and also that, because the land was poor and in a bad state of cultivation, having been washed into gullies, which required extra labor and attention, and because it had nut grass on it, it was more difficult to cultivate and less productive than it would otherwise have been, and, for those reasons, his labor was reasonably worth one-half of all crops made. In support of his contention and testimony that, by the agreement, he was to get all the cotton seed, plaintiff offered to prove, by a number of witnesses, that it was the general custom in that country that, when the landlord furnished all the.fertilizer and planting seed, he got all the cotton seed and half of all the other crops. But the magistrate excluded the testimony. He also excluded testimony offered by defendant tending to prove a quantum meruit, and refused defendant’s request to instruct the jury to consider that defense. Nothwithstanding the ruling of the magistrate, excluding testimony tending to prove a qiiantum meruit, a good deal of testimony was brought out which tended to prove defendant’s allegations as to the condition of the land. The jury found for the plaintiff, and defendant appealed to the Circuit Court. That Court held that the magistrate was right in excluding testimony tending to prove a quantum meruit, but that he was wrong in excluding the evidence offered by plaintiff to prove the custom, which had some probative value as a circumstance tending to prove that defendant’s version of the contract was a departure from the ordinary, and, therefore, to *5 that extent, improbable; that, on the same principle, evidence as to the character and condition of the land was properly admitted, because it tended to prove defendant’s version of the contract, and the improbability of his agreeing to work such land, except upon some special inducement, or departure from the ordinary, such as that contended for by him, to wit, that he should get half the cotton seed. The Court held, also, that the burden was on plaintiff to prove the contract, as contended for by him, and that, by its terms, he was to get all the seed. Upon consideration of the appeal, according to these principles, and upon the assumption of the existence of the custom which plaintiff sought to prove, the Court found that, notwithstanding the custom, the preponderance of the evidence was in favor of defendant’s version of the contract, and reversed the judgment of the magistrate’s Court and gave judgment for defendant, whereupon plaintiff appealed to this Court.

1 In an action at law, such as this is, the jurisdiction of this Court is limited to the correction of errors of law. Therefore we have invariably held, on appeal in such cases, that, when there is no error of law involved in the decision, we have no jurisdiction to review it. But we have held also in numerous cases that when the decision is controlled or influenced by error of law, it is subject to review by this Court.

2-8 We approve the rulings of the Circuit Court as to- the admission and exclusion of evidence, for the reasons stated, but the Court erred in holding that the burden was on plaintiff to prove the contract, and that, by its terms, he was to have all the cotton seed.

In the first place, the Court erroneously assumed that plaintiff alleged the contract, and, having alleged it, the burden was upon him to prove it. The fact is that the contract *6 was alleged by defendant, and, therefore, under the general rule that the burden of proof rests upon him who alleges, the burden was, at least prima facie, on defendant. As plaintiff alleged only that part of the seed sold belonged to him, when he proved that they were part of the crops raised under a share crop contract, such as that testified to by both parties, it followed, as matter of law, that the legal title to the entire crop was in him, and he established, at least prima facie, his right to recover. Carpenter v. Strickland, 20 S. C. 1; Richey v. DePre, 20 S. C. 6; McCutchen v. Crenshaw, 40 S. C. 511, 19 S. E. 140. Therefore, the burden was on defendant to prove that he was entitled, by the terms of the contract set up by him, to a part of the seed. Moreover, as the Court assumed the existence of the custom which plaintiff sought to prove, and as defendant’s version of the contract was a departure from that custom, or out of the ordinary, the burden was upon him to prove the special contract.

It is doubtful whether in his consideration of the case the Court gave the custom the full extent of the probative value which it might have had if plaintiff had been allowed to prove b3r his witnesses what he offered to prove by them, to wit, that the custom was so general and invariable that the condition and character of the land would not justify an inference of a departure from it. Of course, we have no way of knowing whether the witnesses would have so testified, as their testimony was excluded.

For the errors pointed out, the judgment of the Circuit Court is reversed, and the case is remanded for a new trial.
