Many considerations of great weight gave us a right to expect that this commerce should be extended to the colonies as well as to the European dominions of other powers. With the latter, especially with countries exclusively manufacturing, the advantage was manifestly on their side. An indemnity for that loss was expected from a trade with the colonies, and with the greater reason as it was known that the supplies which the colonies derived from us were of the highest importance to them, their labor being bestowed with so much greater profit in the culture of other articles; and because, likewise, the articles of which those supplies consisted, forming so large a proportion of the exports of the United States, were never admitted into any of the ports of Europe except in cases of great emergency to avert a serious calamity. When no article is admitted which is not required to supply the wants of the party admitting it, and admitted then not in favor of any particular country to the disadvantage of others, but on conditions equally applicable to all, it seems just that the articles thus admitted and invited should be carried thither in the vessels of the country affording such supply and that the reciprocity should be found in a corresponding accommodation on the other side. By allowing each party to participate in the transportation of such supplies on the payment of equal tonnage a strong proof was afforded of an accommodating spirit. To abandon to it the transportation of the whole would be a sacrifice which ought not to be expected. The demand in the present instance would be the more unreasonable in consideration of the great inequality existing in the trade with the parent country. Such was the basis of our system as established by the act of 1815 and such its true character. In the year in which this act was passed a treaty was concluded with Great Britain, in strict conformity with its principles, in regard to her European dominions. To her colonies, however, in the West Indies and on this continent it was not extended, the British Government claiming the exclusive supply of those colonies, and from our own ports, and of the productions of the colonies in return in her own vessels. To this claim the United States could not assent, and in consequence each party suspended the intercourse in the vessels of the other by a prohibition which still exists.
