H.J. Hall preaches about the importance of advancing the cause of sobriety and temperance by advocating for a constitutional amendment to replace Federal taxes on alcohol with taxes on individual and corporate incomes. This shift in revenue source will allow the government to abandon alcohol taxes, giving states control over the liquor traffic. Hall emphasizes the need for bipartisan and cross-denominational support, urging churches, legislative candidates, and the press to join in this movement for the betterment of society.
