This' cause is now before us upon motion of defendant in error to dismiss same for failure of plaintiff in error to file briefs. The petition in error herein was filed on the 16th day of May, 1910, but no briefs have been filed by plaintiff in error as required by rule 7 of this court (20 Okla. viii). It follows that, upon the authority of Horner et al. v. Goltry & Sons, 23 Okla. 905, the cause must be dismissed.
