Any amendment or amendments to this constitution may be proposed in either house of the general assembly; and if the same shall be agreed to by a majority of the members elected to each of the two houses, such proposed amendment shall be entered on their journals, with the yeas and nays taken thereon, and referred to the legislature to be chosen at the next general election, and shall be published, as provided by law, for three months previous to the time of making such choice; and if, in the general assembly so next chosen as aforesaid, such proposed amendment or amendments shall be agreed to by a majority of all the members elected to each house, then it shall be the duty of the general assembly to submit such proposed amendment to the people in such manner, and at such time as the general assembly shall provide; and if the people shall approve and ratify such amendment or amendments by a majority of the electors qualified to vote for members of the general assembly, voting thereon, such amendment or amendments shall become a part of the constitution of this state. In pursuance of the provisions of this constitution the eighteenth general assembly of the state of Iowa, to-wit, in the year 1880, adopted as an amendment to the constitution of the state the following: "No person shall manufacture for sale, or sell, or keep for sale as a beverage, any intoxicating liquors whatever, including ale, wine and beer. The general assembly shall by law prescribe regulations for the enforcement of the prohibition herein contained, and shall thereby provide suitable penalties for the violation of the provisions hereof." This amendment, by omission of the clerk of the house of representatives, was not entered in full upon the journals of that body. It was, however, embraced in a joint resolution of the two houses and fully identified by its title upon the journal of the house and senate, and the vote adopting the same was duly recorded by yeas and nays as required by the constitution. The publication of this action of the eighteenth general assembly was duly made in the newspapers prior to the election of the nineteenth general assembly, and at the session of that body another joint resolution was passed in both houses embracing the amendment and reciting the action of the eighteenth general assembly thereon, and this joint resolution passed both houses, and the yeas and nays were fully recorded, and proclamation was made by the Governor of the state, and the people of the state at a subsequent election held on June 27, 1882, after a vigorous canvass of the merits of the question, endorsed and adopted the amendment by nearly thirty thousand majority.
