Tbe plaintiff on bis appeal to this Court has failed to overcome tbe presumption against error. Tbe testimony of bis witnesses falls short of tbe desired result on appeal, because of its indefiniteness and uncertainty as to tbe origin of tbe fire.

Tbe burden is on appellant to show error. It is not presumed. Jackson v. Bell, ante, 336; Bailey v. McKay, 198 N. C., 638, 152 S. E., 893.

Affirmed.
