Waters and water courses, § 31*—instruction as to contributory negligence in action for flooding land. A requested instruction held properly denied, in an action against those cutting and removing timber, for damages to adjoining land from brush and tree tops being deposited in a stream so as to cause an obstruction, to the effect that if the plaintiff did not take steps to compel the owner of the land to remove the obstruction he was guilty of negligence contributing to his injury which would preclude a recovery, since it -tended to raise a false issue.6.
