Whenever it is deemed advisable by the comptroller and treasurer jointly to invest a particular fund, or any portion thereof, in any of the securities provided for by this chapter, or when the same is ordered by the city council, the comptroller and treasurer may make such investment for and on account of such particular fund. In such event the interest, when it becomes due, and the principal, when the same matures and is collected, shall be turned over to the credit of such particular fund so invested.
To the extent that any such particular fund is so invested, it shall not share in the pro rata distribution of interest which may accrue to the aggregate of the funds used for the purchase of securities as herein provided for; provided, however, that such particular fund, as to the surplus which may remain therein after such investment, shall be entitled to its pro rata share of the interest which may accrue to the aggregate of the funds used as aforesaid.
