The following reports of committees of the House of Representatives and of the Senate include usually the "hearings" of the committees, if any have been held: _Report from the Committee on Immigration and Naturalization_, 51 Cong., 2 Sess., H. R. No. 3472 (Owen Report, 1891); 52 Cong., 1 Sess., H. R. No. 2090 (Stump Report, 1892); _Report of the Committee on Immigration_, 52 Cong., 2 Sess., S. R. No. 1333 (Chandler Report, 1893); 54 Cong., 1 Sess., S. R. No. 290 (Lodge Report, 1896); 57 Cong., 2 Sess., S. Doc. No. 62 (Penrose Report, 1902). Special reports of importance are: _Report of the Immigration Investigating Commission_ (1895); Edward Young, Chief of the Bureau of Statistics, _Special Report on Immigration_, (42 Cong., 1 Sess., H. Mis. Doc. No. 19 (1871)); and C. C. Andrews, _Report made to the Department of State on the Conditions of the Industrial Classes in Sweden and Norway_ (1874). In a class by itself is the recent elaborate _Report of the Immigration Commission_, S. Docs., 61 Cong., 2-3 Sess. (Dillingham Report, 1910-1911), 43 vols., of which vols. 1 and 2 (Abstract), 4, 34, and 36 are specially important for this study. The _Report_ is by far the most scientific, thorough-going, and detailed study of the nature, extent, distribution and results of immigration to the United States, and to a few other countries like Canada, Australia, and Brazil, which has yet been produced. Various volumes of the United States _Statutes at Large_ and the _Congressional Directories_ have also some material. 2. _Official Reports of Scandinavian countries._ DENMARK: annual volumes of _Statistisk Aarbog_.
