In 1738 the Government of the United Provinces diminished the value of their _sols._ by one-half. The French Government fearing that this diminution would lead to an immense influx of such sols. decided to follow suit. By a decree of August 1st of the same year, 1738, it was ordered that the _Douzains_ and pieces of thirty deniers should have course only for eighteen deniers. The important point to notice in connection with this is that, in order to mitigate the effect of this reduction, the same decree limited the tender of such billon money. It was ordered that in payments up to 400 livres not more than 10 livres should be tenderable in billon, and for payments of more than 400 livres not more than 1/40 of the total. The restriction was ineffectual in preventing either the import of foreign billon specie or the operations of billonage or arbitrage, based on the differentiated value of the various kinds of billon circulating. This is quite evident from the preamble of the edict of the following October, 1738, which attempted the calling in of the 30-denier pieces, in order to put a stop to the process. [Sidenote: FRANCE: THE REFORM OF 1785] Such a failure is quite in keeping with all previous experience as recorded in these pages, and deserves no special reference. The point to note is rather the gradual evolution and adoption of the idea of limiting the tender of the lower species, so as to contract their action on the main species of the currency. This idea forms the complement of the idea of an agio, involved in the issue of fractional coins on a lower standard or basis than that of the greater specie. The one idea was--in long, over-long, periods i.e.--impracticable without the other; but together, when finally evolved, thoroughly seized and put in practice, they formed the main basis of the truest modern currency system. To return to the pure gold and silver species. The basis of 1726 remained at law unaltered until 1785. The edict of the 30th October of that year commanded a recoinage; no change was made in the silver coinage, which remained according to the tariff of May 1773, namely, 52 livres 9 sols. 2 den. to the mark fine. By the alteration of the tariff of gold, however, to 828 livres 12 sols. to the mark fine, the ratio of 14-5/8, which had nominally prevailed since 1726, was altered to the memorable 15-1/2. The reason was explicitly stated to be the increase in the value of gold during several preceding years--an increase which had banished or detained gold from the French Mint and even from France. Writing in 1785, the minister, Calonne, who proposed and executed the recoinage in that year, spoke thus:--
