Production was well underway at the Times and Seasons as Smith was getting everything ready for the next edition (No 10), which was set to be published in just one week. Smith was going over the finishing touches for the remainder of the text of the Book of Abraham to be published as well as Facsimile No. 2. Notice, curiously, Smith was still involved in "Translating from the Book of Abraham", even at this late date, Smith still considered himself in a translation mode. Despite the manuscripts set to be put to type on the press, Smith was always in revelatory mode concerning his professed ability to translate and he was more than willing to make changes or additions according to his inspiration. What's important to note is that Smith was ever ready to translate and could do so on the fly.

Again, Smith continued to operate in a translation mode whereby any additions or corrections were handled through his instrumentality. The following day, Smith met with the Twelve to have dinner and finished work at the printing office.

The following week, on the 15th, the second installment of the Book of Abraham was published. The installation of the Nauvoo Masonic Lodge was also formerly established and on that evening, Smith was raised to the level of Master Mason. Smith would have access to all the Masonic books and materials available at the lodge.
