In addition to the penalties provided in this chapter for trespass upon lands, the commissioner of university and school lands may seize and take, or cause to be seized and taken, without legal process, any timber, grass, wood, or other property unlawfully severed from the lands, whether the same has been removed from the lands or not. The commissioner may dispose of the property seized either at public or private sale, in the manner most conducive to the interests of the state. After deducting the reasonable and necessary expenses of the seizure and sale, all moneys remaining must be made a part of the interest and income fund of the institution for the support of which the land was granted.
