The immigration of the Chinese has been and continues to be the subject of important legislation. The act of congress of March 3, 1875, Rev. Stat. §§ 2158-2164, prohibits any vessels being built or registered in the United States for the purpose of procuring from any port the subjects of China, Japan, or any other oriental country, known as "coolies," to be transported to any foreign place, to be disposed of or sold as servants or apprentices; § 2158. Vessels so employed shall be forfeited; § 2159. Building, fitting out, or otherwise preparing or navigating vessels for such trade, is punishable by fine and imprisonment; §§ 2160, 2161. But this act does not interfere with voluntary immi- gration; §2162; and no tax shall be enforced by any state, upon any person immigrating thereto from a foreign country, which is not equally imposed upon every person im- migrating thereto, from any other foreign country; § 2164. The immigration of con- victs and women for purposes of prostitu- tion is also prohibited; Supplement to Rev. Stat. p. 181, §§ 3 & 5; 18 Stat. L. 477; 53 Fed. Rep. 1001; also alien laborers; 23 Stat. L. 332; and also all Chinese laborers, whether under contract or not; 25 Stat. L. 476, 504. The act which provides for the exclusion from admission of certain classes of aliens, and which makes the decision of the inspec- tors of immigration adverse to the right of any alien to land, final and conclusive un- less appeal is taken to the superintendent of immigration, is a constitutional exercise of the power of congress; 142 U. S. 651. The government of the United States, through the action of the legislative depart- ment, can exclude aliens from its territory, although no actual hostilities exist with the nation of which the aliens are subjects; 130 U. S. 581. See ALIEN; CHINESE; DE- PORTATION,
