Source of text:
RS:HS 18.265 (C: 22.206)
Summary:

Critiques John Taylor's essay [see AW's 1844-9-26]. Views AW's position on currency measures as too vehement; urges caution. JH conceived similar plan years before. Gives reasons for disowning it. Protests JH's being painted as perpetrator of injustice simply because JH rejected AW's arguments.
