The district court or any judge thereof, may, from time to time, enter such orders as may be necessary, authorizing the guardian of the person of such habitual drunkard to confine and restrain him in such manner and in such place within the state as may, by the court or judge, be considered best for the purpose of preventing such drunkard from using intoxicating liquors, and as may tend to his reformation. [§3468a Sup.] When it is sought to have a guardian appointed for a person of unsound mind, the test of his mental capacity is not the degree of prudence and foresight he manifests in the management of his affairs, for "the law does not assume to measure the different degrees of power of the human intellect, or to distinguish between them where the power of thought and reason exists," but the question to be determined is whether or not he possesses sufficient ability to understand in a reasonable manner the nature and effect of his acts, or the business he is transacting.

If the minor is more than twelve years of age and not a pauper, the indenture must be signed by him of his own free will. [§3472.] [Sidenote: Consent of parent or guardian.] A written consent must be appended to or endorsed upon such agreement, and signed by one of the following persons, to-wit:
