The opinion of the Court was delivered by

The parties hereto are children of the same parents. Their controversy is about 75 acres of land, intermediate, two parcels confessedly owned by each, thus not accurately but illustratively:

*305 The plaintiff owns X; the defendant owns Z; Y is in issue betwixt them.

The disagreement arose out of these circumstances, alleged in the complaint: The parties owned the whole parcel of about 1,000 acres as tenants in common, and they undertook in 1908 to partition it in kind. A surveyor was employed to that end, and commissioners in partition were appointed. The intention of the commissioners was to make an equal division in kind; that is, to set off to each party 500 acres of land. A plat to that end was made, and on it the correct line A, B, was laid down; but in laying that line down on the ground it was mistakenly run as A, C, thus giving the plaintiff only 425 acres and giving the defendant 575 acres. The action is to remedy that mistake, and to now do that which was intended by all parties to have been done at the outset.

The defendant by answer “admits * * * the allotment of one-half each to the plaintiff and the defendant of the * * * said tract of land;” alleges that “the parts of the said land belonging to the plaintiff and defendant are incorrectly described on (the) plat,” etc.; alleges that interchangeable deeds were made by each party to the other “and to equal proportions in area;” and sets up 10 years’ adverse possession of the disputed parcel as a bar to the action.

The testimony was taken by the master, 'and from it the Circuit Court concluded that the plat indicated the true line betwixt the parties, and the plat was part of the deed; that the defendant supposed that the line run on the ground was that run on the plat, and he thought the plaintiff was in actual possession of an equal quanity of land with himself ; but that nevertheless the defendant went upon the land in issue, and has held it adversely for 10 years, and the plainiff is now barred to claim it. The plat showed that the line *306 A, B, was the true dividing line. The Court found the facts correctly, but not the law. There was no room to apply the statute of limitations.

1 The defendant in effect admits that there was a mistake in running the line on the ground, for he testified that he only knew that a mistake had been made in running the line on the ground a year before the action was brought, and that up to that time he had been under the impression that .there had been a fair and equal division of 500 acres to the side. That amounts to saying that he was on the plaintiff’s land, but did not know it, and did not intend to be there.

2 Adverse possession is hostile possession, and hostile possession is possession with intention to dispossess the owner. 3 Washburn (4th Ed.), p. 129.

3 If the statute does not avail the defendant, then he must, of course, now do that which he and the plaintiff first intended to do; that is to say, fix on the ground the line as it was fixed in the Rhodes plat.

The decree below is reversed, with direction to make such order as will carry out the opinion we have expressed.
