70. All bills for raising revenue shall originate in the House of Representatives. The Governor, Auditor, and Attorney General shall, before each regular session of the Legislature, prepare a general revenue bill to be submitted to the Legislature, for its information, and the Secretary of State shall have printed for the use of the Legislature a sufficient number of copies of the bill so prepared, which the Governor shall transmit to the House of Representatives as soon as organized, to be used or dealt with as that House may elect.

All other appropriations shall be made by separate bills, each embracing but one subject.
72.

76. When the Legislature shall be convened in special session, there shall be no legislation upon subjects other than those designated in the proclamation of the Governor calling such session, except by a vote of two-thirds of each house. Special sessions shall be limited to thirty days.
