he Senate to _Enquire into and Examine the Methods of Business and
Work in the Executive Departments_, in 3 vols., known as Cockrell's
Report, or Senate Report 507, 50th Cong., 1st Sess., and also a
supplementary report in one volume, dated March 28, 1889. For other
official sources of information, see the annual reports of the various
departments, and of the individual bureaus. See also special reports
mentioned in the text. On diplomatic relations, see the annual report of
the Secretary of State _On Foreign Relations_, and _Treaties and
Conventions between the United States and Other Powers_ (1776-1887),
published by the same department. The _Consular Reports_, issued from
time to time by the State Department, are of value as furnishing
economic information regarding foreign countries. The reports of the
Secretary of the Treasury are of extreme statistical and financial
value. For handy use the _Statistical Abstract_ is issued annually by
the Treasury Department. The reports published by the Department of
State, of the _International Conferences of 1878_, and of _1881_, and
that of Edward Atkinson on _The Present Status of Bimetalism in Europe_
(1887), are of especial value upon monetary topics. In 1886 the Treasury
Department issued a volume of _Laws Relating to Loans, and the Currency,
Coinage and Banking_. Besides his annual report the Director of the Mint
publishes annually a report on the _Production of Gold and Silver in the
United States_. For an account of the Sub-Treasury system, see Bolle's
_Financial History of the United States_. Concerning the evils of this
system, see an article by Prof. J.L. Laughlin in the _North American
Review_, Vol. 137, p. 552.

Regarding the Silver Question and other important public questions
coming within the province of the Treasury Department, information can
be derived from recent periodicals. Poole's _Index to Periodical
Literature_ should also be consulted. An interesting account of the
Pension Office is contained in the _Atlantic Monthly_, January, 1890.
Regarding the Interstate Commerce Commission, see the book by Don Passes
in Putnam's "Questions of the Day" series. See also Political Science
Quarterly, Vol. II, pp. 223 and 369.

The Eleventh Census is now being compiled, and Bulletins are issued from
