Before we commence to translate that epistle, we must give a brief epitome of the contents of the treatise, which was to be printed in lieu of this treatise, and to which reference has been made in the preceding treatise, and we must write on this 4th of July, 1859 in the midst of great noise and continuous cracking and thunder of guns and so much smell of powder, that it becomes very tedious. This morning it appeared in newspapers, that Samuel Jackson's pyrotechnical establishment on 10th and Reed Streets in Philadelphia was yesterday afternoon destroyed by the explosion of fireworks, which were prepared for the exhibition on this day; but they yesterday burned Mr. Beck to death. We mention this case, because we saw it besides many other cases amongst the news of this day, and this Jackson is one of the many strong mediums of destroying spirits whom we endeavored many years ago to deliver from those spirits; but they continue to prepare tremendous fireworks.

I made use of that opportunity and assured citizens of the United States, that rapping spirits would be dreadful destroying spirits also in this country, if their operations will not be stopped by the application of the means which are comprehended in our message of Peace. But I did not try those spirits in circles of spiritualists, till I received order from my leaders to do so.
