A
  court exercising jurisdiction over the property of an incompetent person
  or conservatee may, upon the petition of a committee of the property  of
  such  incompetent  person  or of the conservator of the property of such
  conservatee, authorize him to advertise for creditors and other  persons
  interested  in  such  estate,  to  present  to him their claims with the
  vouchers thereof, duly verified, and naming  a  post-office  address  at
  which  papers may be served on them by mail, as hereinafter provided, on
  or before a day to be specified in such  advertisement,  not  less  than
  thirty  days  from  the last publication thereof, which advertisement or
  notice shall be published in two newspapers  to  be  designated  by  the
  court  as  most  likely  to give notice to the persons to be served, not
  less than once a week for four successive weeks,  and  a  copy  of  such
  notice  securely  inclosed in a post-paid wrapper, shall be deposited in
  the  post-office  in  the  village  or  city  where  such  committee  or
  conservator  resides,  addressed to each person interested in the estate
  of such incompetent person or conservatee  who  shall  appear  from  the
  books  or  papers  of  such  incompetent  person  or  conservatee  to be
  interested in said estate, or who shall be known to  said  committee  or
  conservator  to  be  so interested, at the proper post-office address of
  such interested person, so far as said committee or conservator shall be
  able to ascertain the same, at least  thirty  days  prior  to  the  time
  limited in such notice for presentation of such claims.
