Section 21. Duties of agent

Such agent shall annually, on or before the
  first Monday of June, prepare and transmit to the department  of  social
  welfare  a  correct  enumeration  of  such  of the Indians of whom he is
  agent, as are entitled to receive annuity moneys  from  the  state.  The
  department of social welfare shall, upon receipt of such enumeration and
  undertaking,  certify  to  the  comptroller  such  enumeration  and  its
  approval of such undertaking and send to such agent the  annuity  moneys
  payable  by  the  state  to  the  Indians  of whom he is agent for which
  purpose such moneys shall be paid to the department  of  social  welfare
  from  the  treasury  on  the  audit  and warrant of the comptroller upon
  requisitions approved by the department of social  welfare.  Such  agent
  shall  thereupon  distribute  such  moneys  to the Indians of whom he is
  agent who are entitled thereto, paying the same to heads of families and
  individuals so far as  practicable,  and  shall  forthwith  report  such
  distribution  to  the  department of social welfare, which shall certify
  such report to the comptroller. Such agent shall protect the rights  and
  interests  of  the  tribe  of  which he is agent, and perform such other
  duties in relation to them as may  be  required  by  the  department  of
  social welfare.
