ian.--Each state has a valuable library, composed chiefly of
law books, but containing also many other valuable books and pamphlets.
This library is open to the public. It is in charge of the state
librarian, who acts under prescribed rules.

Public Examiner.--To render assurance doubly sure that public money shall
be used only for the purposes for which it is designed, provision is made
for the appointment of "a skillful accountant, well versed in the theory
and practice of bookkeeping," to exercise constant supervision over the
financial accounts of state and county officers and of banking
institutions incorporated under state laws. This officer is called the
public examiner.

The officers visited are required by law to furnish the public examiner
facilities for his work, and to make returns to him under oath. The
examiner reports to the governor, who is empowered to take action to
protect the interests of the people.

Oil Inspector.--To protect the people from the danger of burning oil unfit
for illuminating purposes, there is an officer called the inspector of
illuminating oils. The inspector appoints a deputy for each county. It is
the duty of these officers to test the illuminating oils offered for sale,
and to mark the barrel or package containing it "approved" or "unsafe for
illuminating purposes," as the case may be. Penalties are attached to the
selling of oils not approved.

Boiler Inspector.--Steam is now used as power in threshing grain and in
grinding it, in sawing lumber, in propelling boats and cars, etc. To
prevent loss of life, engineers must pass an examination and secure a
certificate of qualification. And boilers must be inspected at least once
a year to prevent explosions. The latter duty devolves upon the state
boiler inspector and his assistants. Locomotive engines on railroads are
sometimes exempt from government inspection, because of the invariably
high skill of the engineers and the great care of the companies.

Labor Commissioner.--Among the questions now receiving consideration from
states and nations are many referring to labor--the healthfulness of
factories, hours of labor, employment of children, protection against
accidents, etc. In many of the states there is a commissioner of labor to
make inspections and formulate statistics pertaining to labor.

Officers Peculiar to Certain States.--There are in some states other
officers, necessitated by special industries. Thus, in Minnesota
