“ In our opinion the section must be taken as making it the plain duty of the Secretary to cause the several payments of income to be made in the amounts and at the times specified, and to invest the excess, where there is such, in prescribed securities, or to deposit it in prescribed banks, for the benefit of those to whom it is owing. The investment clause obviously refers to the moneys which are withheld, not to those which are paid. Where the payment is to a guardian, the county court alone is empowered to direct and control the investment of what is paid. ”

“ If he is an adult and has a certificate of competency showing he is fully capable of managing his own affairs the full share is to be paid; otherwise only a limited sum-$1,000 where he is an adult and $500 where he is a minor. The clause saying, 'except where incompetent adult members have legal guardians, in which case the income of such incompetents shall be paid to their legal guardians,' is not an independent direction, but merely an excepting clause showing that the income which under the principal provision would be payable to the ward is to go to the guardian. ”

“ We hold therefore that the Secretary exceeded his authority in imposing a restriction as to how the money should be invested or deposited after it was paid to the guardian.
For the purposes of these payments the section assigns the members of three major classes. The first comprises all adults having certificates of competency, the second all adults who are without such certificates, and the third all minors. The directions for payment take up the classes in that order. As to the first the direction is that the member be paid his full share of the income. Whatever is due is to be paid. ”
