But this facile procedure could not be carried on _ad infinitum_ except by jeopardizing the convertibility of the notes. Consequently the very increase of paper money, added to the increased demand for currency, compelled the Government to go in for the provision of metallic money for providing current means of purchase and also give a backing to the watered paper issues. The rising price of silver naturally made the Government go in for gold. An Ordinance was issued on June 29, 1917, requiring all gold imported into India to be sold to Government at a price based on the sterling exchange, and opened a gold Mint at [pg 218] Bombay for the coinage of it into mohurs.³³⁷ Frantic efforts were made to acquire gold from various quarters. The removal of the embargo on the export of gold by the U.S.A. on June 9, 1917, and the freeing of the market for South African and Australian gold, enabled the Government to obtain some supply of that metal. From July 18, 1919, immediate telegraphic transfers on India were offered against deposit at the Ottawa Mint in Canada of gold coin or bullion at a rate corresponding to the prevailing exchange rate, and at New York at competitive tenders from August 22, 1919. Arrangements were also made for the direct purchase of gold in London and U.S.A. Finally, to encourage the private import of gold, the acquisition rate was altered from September 15, 1919, so as to make allowance for the depreciation of the sterling. But the gold thus obtained was a negligible quantity. Besides, the issue of gold did not serve the purpose the Government had in mind—namely its retention in circulation. In the nature of things it was impossible. The rupee was depreciated in terms of gold to an enormous extent, and consequently at the rate of exchange gold passed out of circulation as quickly as it was issued by the Government. What the Government could do was to make the use of gold and silver coins illegal for other than currency purposes and to prevent their exportation, which it did by the Notifications of June 29 and September 3, 1917. Realizing that it could not rely upon gold, the Government renewed its efforts to enlarge the rupee coinage. To facilitate the purchase of that metal the import of silver on private account into India was prohibited on September 3, 1917. This measure, however, removed only a few of the smaller competitors for the world’s diminished supply of silver, and the world-demand remained so heavy that the Secretary of State was unable to obtain sufficient supply notwithstanding the great conservation effected in the use of silver by substituting nickel coinage for silver coins of subsidiary order,³³⁸ and by the issue of notes of denominations [pg 219] as low as that of R.1³³⁹ and of R.2–8.³⁴⁰ The Government of the United States was therefore approached on the subject of releasing a portion of the silver dollars held in their reserve.
