M'wILLUMS V. WITHINGTON. 329 misiakcn description, of which land the debtor, Bouse, T^'as, and for a long time had beea, in possession, it was held that the purchaser had an equity which could be enforced by proper proeeedings, and that, whenever a party is in such a situation as to be entitled to call for a specifie performance, he then has such an interest as may be transferred by execu- tion sale. "And as a matter of course," says the court, "when the law once annexes to the debtor's interest in land the incident of transferability, it must manifestly follow that the puroliaser will immediately succeed to and occupy the statua of him whose estate the slieriff's deed purports to convey ; otherwise the statute respecting execution sales would be utterly inoperative, so far as regards equitable interest in land."

For the breach of this covenant h& may have an action. " It was," says the court, "a covenant incident to the estate made for its security and protection, benelicial to the person to whom the estate should corne, but to no other. It was part of the debtor's right, title, and interest in the premises." The legal effect and operation of the sheriff's deed was tO' transfer this covenant to the purchaser. When the covenant runs with the land it is immaterial whether it pass by deed from the grantee or by a sheriff's deed. The grantee iri the^
