On November 20, 2012 I conducted WorldCat search and found only 3 libraries in the world have a copy of this 1881 edition of this work.
The author was a freethinker and established the "Truthseeker" newspaper in 1873. He was a prolific author and published numerous works.
In 1879 D. M. Bennett went on trial for blasphemy, or as he later wrote about his conviction, “imprisoned ostensibly for depositing prohibited matter in the mail, but really for entertaining and speaking his honest convictions.” His sentence was that “you be confined, at hard labor, for a period of thirteen months, and to pay a fine of $300. The sentence to be executed in the Albany Penitentiary.”
After being released from prison Bennett's friend held a reception for him at Chickering Hall in New York, and, as the author notes, the hall "could not hold more than half the sympathetic people who assembled on that occasion."
The letters he wrote to his friends, and which were published in the "Truthseeker," were so well received that upon his return a firiend, D. C. Coleman, proposed that he make a tour "around the world, and write it up, and make a book of the same" and he and hundreds of others would pay $5.00 in advance to cover the costs for this trip.
This latter trip began in 1881, ended July 3, 1882 with a last letter from Colorado, and a 4 volume work entitled "A Truth Seeker Around the World."
