A Yankee in Canada with Anti-slavery and reform papers

First edition, edited by Sophia Thoreau and W.E. Channing.
The first three chapters of ''A Yankee in Canada'' appeared in Putnam's magazine 1858 under the title of ''Excursion to Canada''.
''Prayers'' one of the essays of the ''Anti-slavery and reform papers'' was attributed to Thoreau by mistake, only a prayer in verse included being his.  The essay itself, first published in the Dial, is by Emerson and is now published in his Natural history of the intellect.
