To serve the purpose for which these clauses of the Constitution are invoked, it is necessary to hold that any territory to which the United States has a title is an integral part of the United States; and perhaps the greatest name in the history of American constitutional interpretation, that of Mr. Chief Justice Marshall of the Supreme Court of the United States, is cited in favor of that contention. If accepted, it follows that when the treaty ceding Spanish sovereignty in the Philippines was ratified, that archipelago became an integral part of the United States. Then, under the first clause above cited, the Dingley tariff must be immediately extended over the Philippines (as well as Porto Rico, the Sandwich Islands, and Guam) precisely as over New York; and, under the second clause, every native of the Philippines and the other new possessions is a citizen of the United States, with all the rights and privileges thereby accruing. The first result would be the disorganization of the present American revenue system by the free admission into all American ports of sugar and other tropical products from the greatest sources of supply, and the consequent loss of nearly sixty millions of annual revenue. Another would be the destruction of the existing cane- and beet-sugar industries in the United States. Another, apprehended by the laboring classes, who are already suspicious from their experience with the Chinese, would be an enormous influx, either of cheap labor or of its products, to beat down their wages.
