Fourth, that a guard should be kept constantly on the watch, both night and day, about the house, to protect the manuscript from malicious persons, who would infest the house for the purpose of destroying the manuscript. All these things were strictly attended to as the Lord commanded Joseph. [3] These precautions, at first glance, may seem excessive, and under ordinary circumstances would be totally unnecessary; yet the following communication to the _Signs of the Times_, by J. N. T. Tucker, who was employed in the printing establishment of the _Wayne Sentinel_, in the establishment at which the Book of Mormon was printed, in Palmyra, will demonstrate that the precaution in this case was necessary; and incidentally tends to prove true the statement of the revelation in which the Prophet Joseph is warned that the 116 pages of manuscript stolen from Martin Harris were changed by those into whose hands they had fallen, with the intention to make them conflict with the reproduction of them, should the Prophet again translate that part of the work. With these preliminary remarks the following letter will be self-explanatory: "MORMONISM"--SOME CURIOUS FACTS _Messrs. Editors_:--Having noticed in a late number of the _Signs of the Times_, a notice of a work, entitled, _Mormon Delusions and Monstrosities_, it occurred to me that it might, perhaps, be a service to the cause of truth, to state one circumstance in relation to the authenticity of the Book of Mormon, which occurred during its publication, at which time I was a practical printer and engaged in the office where it was printed, and became familiar with the men and their principles, through whose agency it was "got up." The circumstance alluded to was as follows: We had heard much said by Martin Harris, the man who paid for the printing, and the only one in the concern worth any property, about the wonderful wisdom of the translators of the mysterious plates, and resolved to test their wisdom. Accordingly, after putting one sheet in type, we laid it aside, and told Martin Harris it was lost, and there would be serious defection in the book in consequence, unless another sheet like the original could be produced. The announcement threw the old gentleman into quite an excitement. But after a few moments' reflection, he said he would try to obtain another. After two or three weeks, another sheet was produced, but no more like the original than any other sheet of paper would have been, written over by a common schoolboy, after having read, as they did, the manuscript preceding and succeeding the lost sheet.
