The 'brief of appellant on, this appeal contains no assignment of error, and, for that reason, there is nothing before this court for consideration. The proper assignment of error is essential to the jurisdiction of this court. In re Election of Directors and Officers of Cumberland M. & M. Co., 153 N. W. 761; John Seubert v. Fawick Tractor Co., recently decided by this court, 154 N. W. 446.

The order appealed from is affirmed.
