delivered the opinion of the court. We do not perceive that this case differs essentially from what it was in 1872, when it was dismissed for want of jurisdiction in this court to hear it. In the Supreme Court of the State it was an appeal from an inferior court, in which it had been sought to enforce an alleged trust, by a bill in equity, and the bill was ordered to be dismissed, because the court was of opinion no trust was proved. The record does not show that the question whether the sale of the land warrant was a nullity if made before the warrant issued, was passed upon, much less that it was decided against the complainant. The decree ordering the bill to be dismissed must *374have been made, if it had been decided that the sale was void. Even then it would have been necessary to establish the existence of a trust. What amounts to a trust, or out of what facts a trust may spring, are not Federal questions, and on a writ of error to a State court we can review only decisions of Federal questions. The case is covered by Smith v. Adsit, in 16 Wallace.

Writ of error dismissed.
