If any intermediary entitled to receive compensation in respect of any interest is a person incompetent to alienate such interest, the compensation officer shall keep the amount of compensation payable, in respect of such interest, whether in cash or in bonds, in deposit with the Collector who shall arrange to invest the cash or the income from the bonds in the purchase of such Government or other approved securities as the Collector thinks fit and shall direct the payment of the income from such investment to the intermediary who would for the time being have been entitled to hold and enjoy such interest if it had not vested in the Government; and such cash, bonds and securities shall remain so deposited until they are made over to any person or persons becoming absolutely entitled thereto:
     Provided that nothing herein contained shall affect the liability of any person who may receive the whole or any part of any compensation under this section to pay the same to the person lawfully entitled thereto.
