Section 36. If during the continuance or upon the termination of a trust under a will or written instrument one of the beneficiaries becomes an absentee as defined in section twenty-six, the trustee may pay the income or distribute the trust estate to the known beneficiaries in the proportions to which they would be entitled if such absentee were present in the commonwealth, and as to the remaining part to which such absentee would be entitled if present, such trustee or any person who would be interested in the share of such absentee if he were dead may take like proceedings with reference to such share as are provided for in the ten preceding sections.
