Where any property is held by a trustee in trust for a minor, such trustee may, at his discretion, pay to the guardians (if any) of such minor, or otherwise apply for or towards his maintenance or education or advancement in life, or the reasonable expenses of his religious worship, marriage or funeral, the whole or any part of the income to which he may be entitled in respect of such property; and such trustee shall accumulate all the residue of such income by way of compound interest, by investing the same and the resulting income thereof from time to time in any of the securities mentioned or referred to in section 20, for the benefit of the person who shall ultimately become entitled to the property from which such accumulations have arisen: Provided that such trustee may, at any time, if he thinks fit, apply the whole or any part of such accumulations as if the same were part of the income arising in the then current year.
     Where the income of the trust-property is insufficient for the minors maintenance or education or advancement in life, or the reasonable expenses of his religious worship, marriage or funeral, the trustee may, with the permission of a principal Civil Court of original jurisdiction, but not otherwise, apply the whole or any part of such property for or towards such maintenance, education, advancement or expenses.
     Nothing in this section shall be deemed to affect the provisions of any local law for the time being in force relating to the persons and property of minors.
