confirmed land title

Where there is a specific tract of land confirmed according to ascertained boundaries, the legal effect of the confirmation is to establish the right and locate the claim, but where the claim has no certain limits, and the decree of confirmation carries along with it the condition that the land must be surveyed, and severed from the public domain and the concessions of other parties, then it is beyond controversy that the title of the claimant, although confirmed, attaches to no land, nor has a court of justice any authority in law to ascertain and establish the boundaries, as that power is reserved either to the executive department or to Congress.
