But other conditions have arisen. That suggested to your committee the necessity of still keeping upon the statute books the prohibition against slavery. because while slavery at that time was confined to the persons designated in the prohibitive sections. yet now the slave trade has extended to people who do not come within that designation. It is of comparatively frequent occurrence. unfortunately. that our vessels or the vessels of other countries bring to our shores people who are held in slavery. to be sold in slavery. that do not come within that designation of "negroes. mulattoes. or persons of color." People from Japan. people from China. people from some other Asiatic and European countries are brought here under contract that amounts to slavery. perpetual slavery. brought here for immoral purposes oftentimes. sold as slaves were sold. Whether the designation of "slave" is applied to them in the contract is immaterial. If the effect of their contract is to enslave these people. then it is proper and right that there should continue always to be upon our statute books such prohibitive legislation as will enable the laws to reach such people.
