In 1891 an act was passed by the General Assembly prohibiting the formation of trusts but no specific duties were assigned to the Secretary of State until the law was amended in 1893 (L. 1891, p. 206; L. 1893, p. 89). The Secretary then was instructed to require every corporation doing business in the state to file an annual affidavit affirming that it was not a member of or party to any pool, trust, or combination in restraint of trade. In 1895 another law was passed providing an appropriation for anti-ust clerks (L. 1895, p. 49). After 1919 these statements no longer were required to be filed with the Secretary of State (L. 1919, p. 312).
