240	THE  CURRENCY  REPORT

emergency arose requiring an increase in the amount
of fiduciary currency, this should not involve a
breach of the law, but should be made legal (as it is

1914), subject to the consent of the Treasury.
It is not proposed at present to secure the circula-

making the notes convertible, at the discretion of the
Bank of England, into coin or bar gold. The
amount which, in the opinion of the Committee,
should be aimed at for the central gold reserve is
£150 millions (a sum which is already almost in sight:
on its figures quoted above) ; and " until this amount
has been reached and maintained concurrently with
a satisfactory foreign exchange position for a period
of at least a year/' it thinks that the policy of re-
ducing the uncovered note issue " as and when
opportunity offers " should be consistently followed.

made clear; but presumably a rcflow of notes from
circulation can only happen through a fall in prices
