Under a will establishing a trust and directing that at the death of the life beneficiary the trust fund should "be divided in accordance with the residuary clause," which disposed of the residue "including all reversions and remainders," the trust fund on the death of the life beneficiary did not become payable to the legatees named in the residuary clause as designated remaindermen but must be treated as part of the residue and must be applied to satisfy existing deficiencies in pecuniary legacies in priority to payment to the residuary legatees. 
On a petition for instructions by one as trustee under a will of which he was also executor, the court could not give binding instructions respecting his duties as executor unless he became a party to the proceeding in that capacity also.  Upon a fund constituting part of the residue of a testator's estate becoming available to the executor for the payment of deficiencies in pecuniary legacies existing because available assets of the estate had been originally insufficient to pay them in full, the fund should be applied, first, to pay unpaid balances of the principal of certain legacies directed to be "satisfied in full before the others are paid,"less Massachusetts inheritance taxes; second, to pay the interest on such balances; third, to pay the principal of the nonpreferred legacies, less Massachusetts inheritance taxes; fourth, to pay the interest on the nonpreferred legacies; fifth, to pay without priority the amounts deducted from preferred and nonpreferred legacies for Massachusetts inheritance taxes in accordance with a direction in the will to the executor to pay such taxes "from the funds in his hands, included within the residue"; and last to pay the residuary legacies. [736-737]
In the absence of contrary provisions in a will, legatees of pecuniary bequests directed to be paid "in full" but deferred in payment in whole or in part for many years after the testator's death because of original insufficiency of the available assets of the estate, were entitled, upon payment of the unpaid principal amounts from funds which had ultimately become available, to payment also of interest on such principal
amounts computed at the rate of four per cent from the date one year after the death of the testator. 
The court had no jurisdiction in a proceeding for instructions by a trustee under a will to instruct him as to the proper determination of the income tax upon capital gains of his trust.

WILLIAMS, J. This is a petition by the surviving trustee of a testamentary trust, established under clause 211 of the will of Albert H. Whitin, late of Northbridge, for instructions as to the disposition of the trust fund. The testator, who died on March 6, 1935, left a will containing two hundred twenty-one numbered divisions, described therein as "clauses." There were four codicils. The first codicil contained sixty clauses in modification or substitution of clauses in the will and in the last three changes were made in the names of executors and trustees.
By clause 211 of the will, $400,000 was left in trust to pay
the income semiannually to the testator's niece Mary Alice Larkin, nee Whitin, during her life with provision that "At her death, the said trust fund shall be divided in accordance with the residuary clause of this will." Clause 220 of the will, which contained the provisions regarding disposition of the residue, was revoked by clause 60 of the first codicil and the following clause substituted: "Clause 220. All the rest and residue of my property, real, personal and mixed of every description and kind, including all reversions and remainders, to the amount of twenty thousand (20,000) dollars, I give, devise and bequeath in equal parts to the American Antiquarian Society in Worcester, Massachusetts, and the Anglo-American Nursing Home in Rome, Italy. The balance of said residue in excess of twenty thousand (20,000) dollars, if any, I give, devise and bequeath to my devoted young cousin, Midshipman Willard A. Saunders of the United States Naval Academy at Annapolis, Maryland."
By clause 219 of the will it was provided:
"If any of the legatees named in the foregoing clauses are not living at the date of my death, then the sums which would have belonged to such legatees if living, shall become part of the residue of my estate except as otherwise specified therein.
"If my estate does not amount to a sufficient sum to pay all the foregoing bequests in full, then I direct that the clauses creating trust funds and those making bequests of five thousand dollars (5000) or more shall be satisfied in full before the others are paid.
"Except as provided in the preceding paragraph, I direct that all bequests under this will shall be paid in full and if at the time any of such bequests are paid, there is any state, national or other law requiring a tax to be paid upon the same, I direct my Executor hereinafter named to pay said taxes from the funds in his hands, included within the residue."
The same persons were appointed as executors of the will and trustees of the trusts created by the will, and the petitioner is not only the surviving trustee of the trust under clause 211 but also the surviving executor.
On April 28, 1936, the executors, having ascertained that the estate was insufficient to pay all legacies in full, filed a petition in the Probate Court for instructions as to various matters concerning the administration of the estate and the construction of the will and first codicil. On reservation and report without decision to this court it was determined which legacies under the provisions of clause 219 should have preferential payment. Smith v. Livermore, 298 Mass. 223 . After stating that it was the duty of the executors to pay to themselves as trustees the amount available for the trust fund under clause 211, the court said, "since the time for the distribution of the trust fund created by this clause has not arrived, it does not appear that the petitioners require specific instructions as to such distribution at the present time" (pages 240-241).
The life tenant of that trust, Mary Alice Larkin, died on May 17, 1954, and the time for distribution of the trust fund has now arrived. It is alleged by the petitioner and not controverted in the answers of the respondents that: In accordance with the decision in Smith v. Livermore, supra, and pursuant to the decree after rescript entered in that case, the executors paid to the preferred legatees, as defined in clause 219, ninety-one per cent of their respective legacies less the Massachusetts inheritance taxes upon the same and paid nothing to the deferred or residuary legatees. Ninety-one per cent of $400,000 less the Massachusetts inheritance tax upon the interest of the life tenant was paid to the trustees of the trust created by clause 211. The fund of this trust when established amounted to $352,362.26 being ninety-one per cent of $400,000 less the Massachusetts inheritance tax on the life interest. The petitioner is now converting the trust fund into cash and believes that it will amount to approximately $591,000 by reason of appreciation of investments. [Note 1] There are expenses in connection with the closing and distribution of the trust estate, Federal and Massachusetts income taxes upon the capital gain, and Massachusetts
inheritance taxes upon the amounts to be distributed to legatees, all of which must be paid from the fund. Exclusive of clause 211 there are preferred legacies of which the unpaid nine per cent amounts to $107,775. The preferred legatees number one hundred forty-two. The Massachusetts inheritance taxes which were deducted from the ninety-one per cent paid amount to $60,193.86. There are one hundred five deferred legacies totaling $124,700.
The petitioner prays that he be instructed:
A. Should the balance of the fund after payment of taxes and expenses be distributed to the residuary legatees or applied to the payment of the deficiencies in the legacies?
B. In what order or for what purposes should this balance be used?
C. In what manner should the taxable percentage, if any, of the capital gain be determined in view of the fact that at the date of the death of the testator and also at the date of the termination of the trust there were legatees, both preferred and deferred, who were not residents of Massachusetts, and further that such capital gain resulted from the sale of assets subsequent to said termination?
The petition comes to us on reservation and report, without decision by the Probate Court. Except for the surviving executor of the will, it appears that all persons having interests in the fund are named respondents including the members of the State tax commission of the Commonwealth. Many respondents have appeared and answered.
The instructions to be given are substantially the same as those ordered to be given to the executors in Smith v. Livermore, 298 Mass. 223 . In that case, to which hereafter reference will be made only by page, all clauses of the will and first codicil were carefully considered, and their proper construction determined. It was only because the distribution of the trust fund under clause 211 did not at that time present a present problem that a decision in reference to it was not made. Regarding clause 3 of the will, whereby a trust was created to pay the income to one Brown for life with provision that "At her death said fund shall be distributed
in accordance with the residuary clause of this will," we said, "This clause does not purport to make gifts, after the death of the life tenant, to beneficiaries named in the `residuary clause' as designated legatees . . ., but rather provides that the fund should be subject in all respects to the provisions of the `residuary clause'" (page 238). "Clauses 3 and 220, as changed, read together . . . mean that the reversion or remainder created by the former clause is to be treated as a part of the residue of the estate. As such, it is subject to the payment of deficiencies in pecuniary legacies -- deferred as well as preferred under the second paragraph of clause 219 -- in priority to payments to residuary legatees" (page 239). The same rulings are required as to clause 211. The provision in that clause for final disposition of the trust fund differs from that in clause 3 only in the use of the word "divided" instead of the word "distributed." These words, considered in their context, have the same meaning, namely, that when by virtue of clause 220 the respective reversions or remainders become a part of the residue they should be subject to the payment of legacies in accordance with the terms of the residuary clause. The use of the word "divided" manifests no intent on the part of the testator that an artificial residue be created from the remainder of the trust fund, out of which legacies should be paid prior to payment of previous pecuniary legacies (see page 239).
The trust fund held by the trustee is to be applied, as was the fund under clause 3, to the payment of deficiencies in pecuniary legacies (page 239). In answer to his request designated A, he should be instructed, after payment of taxes and expenses, to pay the balance of the fund to himself as executor to be used for the purpose we have indicated.
Request designated B pertains to the order in which payments of legacies and inheritance taxes shall be made. As to this matter the trustee needs no instruction as he has no duties to perform in respect to the administration of the testator's estate. Doubtless, as suggested in the brief of one of the respondents, as the petitioner was both surviving
trustee and surviving executor he intended to obtain instructions for his guidance in both capacities; but as executor he is not a party to these proceedings. A petition for instructions is in the nature of a bill of interpleader and is governed by rules of equity practice and procedure. Burroughs v. Wellington, 211 Mass. 494 , 496. Wellesley College v. Attorney General, 313 Mass. 722 , 730. No decree which may be entered, instructing him in his duties as executor, will be binding until he comes before the court in such capacity. Since, however, no party has raised the point, we think instructions should be given to the executor as requested in B on the assumption that the Probate Court will allow the petition to be amended by inserting after the words "as he is" in its second line the words "the surviving executor and" so as to read, "as he is the surviving executor and the surviving trustee."
From the balance of the trust fund transferred to the estate by the trustee the executor shall pay all preferred legacies "in full" as directed in the second paragraph of clause 219, except the legacy bequeathed under clause 211. This will involve first the payment of the balance of nine per cent remaining due on the principal of each legacy less the Massachusetts inheritance tax, which must be deducted as required by law; and second the payment of interest on each unpaid balance computed at the rate of four per cent from March 6, 1936, one year after the death of the testator (pages 244-245). Interest on an unpaid legacy is regarded as an incident of or accretion to the legacy, Kent v. Dunham, 106 Mass. 586 , 591; Ogden v. Pattee, 149 Mass. 82 , 84; Loring v. Thompson, 184 Mass. 103 , and should be added to the principal of each legacy to fulfil the requirement of payment "in full."
After satisfying the preferred legacies the executor shall next pay the principal and then the interest due on the deferred legacies, computed at the rate of four per cent from March 6, 1936, less deductions for the inheritance taxes. The testator intended that no legatee should have his legacy permanently diminished by the deductions for inheritance
taxes which the executor was obliged to make. By the third paragraph of clause 219 he directed the executor "to pay said taxes from the funds in his hands, included within the residue." As there will be no residue until bequests are satisfied in full (see page 248) there will be no fund from which the inheritance taxes can be paid until all legacies both preferred and deferred are paid as to both principal and interest. If and when a residue is established it shall be used to pay all legatees both preferred and deferred the amounts deducted from their legacies for the payment of inheritance taxes. The will appears to provide no priority in reference to such taxes. Payment of the residuary legacies will follow the payments for which provision is made as above.
We are precluded from instructing the trustee as requested in C because, as we understand the request, it requires a determination of the question whether for the reasons suggested he is entitled to deductions from the tax assessed on the capital gain of the trust. It is settled that equity will not interfere to determine the validity of a tax. Macy v. Nantucket, 121 Mass. 351 . Welch v. Boston, 208 Mass. 326 , 328. Maley v. Fairhaven, 280 Mass. 54 , 56-57.
In case the estate is not sufficient to pay the deferred legacies in full with interest, the amount available for such payment shall be prorated among these legatees. Similarly if the deferred legacies have been satisfied and the amount thereafter remaining is insufficient to pay to the legatees the sums deducted from their legacies for payment of inheritance taxes, this amount shall be prorated among the legatees whose legacies were taxable.
There is included in the record a motion of the residuary legatee Willard A. Saunders addressed to the Probate Court to vacate that part of the final decree after rescript entered after the decision in Smith v. Livermore which instructed the executors not to pay directly to the residuary legatees "whatever sum remains of the trust fund given by clause 211 of the will at the death of the life tenant." In view
of our instructions to the executor contained in the instant opinion, we need not consider the merits of this motion, if, which we do not intimate, it is properly before us.
If within thirty days the petition is amended to include the executor as a petitioner a decree is to be entered in accordance with this opinion. If there is no such amendment a decree is to be entered in accordance with so much of this opinion as applies to instructions given to the trustee. The allowance of costs and expenses is left to the discretion of the Probate Court.
[Note 1] At time of oral argument it was stated that approximately $585,000 was realized resulting in a capital gain of $230,000.
