E. D. Howe claims Joseph Smith was searching for Captain Kidd’s money when he claimed to have found the plates.

Not only this, if we are to take the brass plate revelation for sacred truth, we must infer that there has been a great deficiency in the record of our Savior’s mission, or that he did not exhibit his truths while here, as fully, and as clearly as he did to these Nephites, through their prophets; and consequently left the world in darkness, to grope their way in superstition and ignorance, until the mineral-rod necromancy of Joseph Smith, Jun. searching after Robert Kidd’'s money, which was buried in Manchester, Ontario county, New York, found the plates of Nephi, which had been buried there one thousand four hundred and twenty-eight years. How long he kept them, we are not informed; but they were taken from him, and hid up again by the Lord, so that no divination, nor legerdemain, will enable him to find them.
