Mr. Justice Holmes

delivered the opinion of the court. '

This is an appeal from a. decree, of the Court of Appeals fif the District- of Columbia affirming .a decree of. the Supreme .Court upon-a-bill of review, brought by Gabriella K. Jordan, the appellee'. The decVee. under'review was- rendered in a suit for the construction of the will of -Thomas Kearney and for the determination of the' validity of a trust created by it, so- far as the .same concerned land in the District of Columbia.-That decree declared' the trust'bad as attempting to create a perpetuity. Under the bill of review- the decree was modi-, fied, on demurrer, to the extent of the interest of Gabriella K. .Jordan, .and - the trust was declared; valid. as to her.- 25 App. D. C. 291. The executors' of the' testator’s heir and, a daughter of the said heir appealed to this court'.'

Thomas Kearney died on July .5, 1896, • The will disposes of lan'd-in various /places. 'In item 3 it enumerates the tes *61 tator’s property in Washington. In item.5,' it devises this and' other, property upon a trust tp-be continued until January 1, 1928, and there-and elsewhere, with the following ' exception, .mak.es a fund from the .Washington rents and., profits to be disposed of as directed in the will. Item 6 is as follows:

“I hereby authorize and direct .that my said trustees shall during the natural life of my beloved niece-, Gabrieíla K-. Jordan, pay over to her regularly each month, ah soon as collected, all rents and revenues collected or derived- from that certain property described, in the third item hereof.as lot No. 611 ‘M’ Street, Nr W., Washington, D. C.-;, but, in case said' rents and- revenues shall at any time be -less than the sum of forty dollars for any one or' more months; then my said trustees are. hereby authorized and. instructed-to add to the-suin, so collected a sufficient, amount to make the said amount-of forty dollars for/each and every month; it" being my de-~ sire that she shall have a regular income of at least, forty dollars per month, • and that, the same shall be p'aid ovér to "her monthly; but if the income'derived from said premises shall'amount to a sum in excess .of forty .dollars per month; she shall'.have,-the whole thereof.!’ i •

Item 7 directs the trustee to let-all the Washington prop-' erty,' except 611 M street, and,out of the rents to pay ninety dollars'a month to the .testator’s daughter, fconstanee' K. Vertner, as ordered in item 5; the residue, so- far as necessary, to be applied to the support and education of her three children, named, with further provisions. Item 8 ,give.s the remainder in fee of 611 M street to the -testator’s .grandson, provided that. If Gabriella Jordan dies before January 1, 1928, he shall- only receive the rents and profits, and if she dies before the grandson reaches the. -age of twenty-dwo the. rents shall be disposed of - as provided in ¡item 7 as. to other Washr ington property. In item 21 the testator, “for .fear that there may be some difficulty in 'construing the. different provisions” of the will, states his -intention that all the money *62 arising from the Washington rents, “except that which is to go to Gabriella K. Jordan, shall be placed in a common fund for the payment (1) of taxes, insurance and repairs on said property and of the premises at Luray, Virginia; (2) of (90) ninety dollars per month to my said daughter, Constance K. Vertner during her natural life; (3) for the support, education and maintenance of my said three Vertner grandchildren until Lillie K. Vertner shall havé arrived at the age of nineteen years, and until Edmund K. and Thomas K. shall have arrived at the age of twenty-two years, respectively.”- .

The persons in whose favor were made the provisions which' were adjudged bad were one of the testator’s heirs,-his daughter, Constance K. Vertner, and the children of Constance. The daughter pleaded that the other heir, Edmund Kear-ney, also provided for in the will, died, leaving her his heir, that the trust was bad, and, 'by implication, that she was entitled to the property which it embraced. She now is dead. By the original, decree the whole trust fund, including that given to Gabriella Jordan, went to the testator’s heirs as property undisposed of by the will. The only person dissatisfied with that decree was Gabriella Jordan, and on the other hand the executor and children of Constance are' the only appellants from the decree on review. According to the rule that has been laid down in this court, Gabriella, as she did not appeal, cannot go beyond supporting the decree and opposing every assignment of error. Mount Pleasant v. Beckwith, 100 U. S. 514, 527; The Stephen Morgan, 94 U. S. 599; Chittenden v. Brewster, 2 Wall. 191, 196; Field v. Barber Asphalt Paving Co., 194 U. S. 618, 621. We assume this rule to be correct. Although her counsel attempted to argue the validity -of the trust as "a whole, and other questions, we assume, without deciding, the decree to be unimpeachable and right except so far ’as appealed from. Therefore we shall confine' ourselves to considering whether the gift to Gabriella is so intimately connected with the failing scheme as to fail -with it.'

*63 It would be a strong thing to say that we gather from this will an intent that, if the trust so far as it concerns the testator’s descendants should fail because they prefer to take the property by intestacy free from the limitations of the will, therefore the one gift outside his family should be defeated also. The trust is not a metaphysical entity or a Prince Rupert’s drop which flies to pieces if broken in any part. It is a provision to benefit descendants and a niece. There is no general principle by which the benefits must stand or fall together. It is true that all the .Washington property was given to the trustees in one clause and that a part -of the scheme in favor of the testator’s grandchildren was the creation of a fund from the rents. But, as is stated in item 21, 611 M street was excepted from the scheme, and the whole income of this lot, or in other words an equitable estate in the specified land, is given to Gabriella, Jordan for life by item 6. If that were all we see no reason for a doubt that that gift would be good, whether the gifts to the other beneficiaries were good or not: The fact that the testator’s daughter takes ali the rest of the property instead of her children getting a postponed interest in a part, is no ground for denying to the niece the life estate given to her in an identified and excepted piece of land. It does not make the case any worse that a part of the property thus going to the testator’s daughter is the remainder in the estate given to his niece.

The appellants lay hold of the instructions to the trustees to add to the rents enough to make Gabriella’s income up to forty dollars a month, and argue as if the gift were in substance only a gift of forty dollars a month from a fund that cannot be established. Such is not the fact. The gift is primarily and in any event a gift of the income of 611 M street. But whatever may be the fate of the rest of the trust we see nothing to hinder the trustees from keeping the income up to forty dollars from the other property devised to them. Of course they could not derive income from property not included in the trust, and. only the property included'is charged with *64 the liability. The decree may be modified by inserting after the words “against his entire estate” the words “in the District of Columbia.”

It is objected in argument, although not in the pleadings, that the widow of Edmund Kearney has a right of dower in the Washington estate which descended to him, and that she should have been made party to the bill of review. The fact of the widow’s existence does not appear of record as against the appellee, and we agree with the Court of Appeals that the. objection is made too late.

Decree affirmed.
