Here is another instance of a magnificently comprehensive law, by which Nature vindicates her right to reign in the domain of Exchange. It is through this natural and beneficent law of automatic compensations, stimulating exportations on the one side and slackening them on the other, that most of the casual disturbances of the commercial par as between two countries are easily and perfectly rectified. While this great law is in full possession of our minds, let us note in passing how artificial restrictions by one country on the importation of goods from another, commonly called "Protectionism," affects this commercial par as between those two countries. Besides stopping absolutely a mass of otherwise profitable exportations and importations for both countries, it makes less profitable to the country imposing the restrictions whatever foreign trade _does take place_ between them in spite of the restrictions. Suppose England, as is the fact, opens her ports freely to the commodities of France, while France puts restrictions in the shape of heavy taxes upon importations from England; more French goods are likely under these circumstances to seek English ports than English goods to seek French ports, because they are more welcome; consequently, more bills of exchange drawn on London will naturally be offered in Paris than bills on Paris in London, and will so far forth be sold at a discount, while the London bills drawn on Paris will be sold at a premium; in other words, the comparatively few goods that do get out of a "protected" country, realize less to their owners than the natural value, because the bills drawn on them are extremely apt to be sold below par! With this course of things all known facts agree. Since the United States became conspicuously a "protected" country a quarter of a century ago, it has been at rare intervals and for short periods that bills drawn here on London have been at par. They have been usually much below par. The equivalent of £1 sterling in United States money is $4.8665; and when bills on London sell for less per pound sterling than $4.86, they are at a discount in New York or Boston; and exporters here are direct losers to the extent of the discount.
