The petition in error, with transcript attached, was filed in this court on March 19, 1910. The cause was duly assigned for hearing at the January, 1912, term, and, being reached in due course on the calendar, it appears that no briefs have been filed as required by rule 7 (20 Okla. viii, 95 Pac. vi) of this court.

It follows that the appeal must be dismissed.
