This notebook covers the period April-October 1899. It was used by Edison's legal counsel, Alexander Elliot, Jr., for notes, opinions, and drawings relating to cement properties at Stewartsville and several locations in Pennsylvania. The earliest items mention meetings with Edison. One entry describes the Hercules Portland Cement Co. in Allentown, Pennsylvania. The front cover is labeled "From the Laboratory of Thomas A. Edison," "The Edison Portland Cement Co.," and "Alexander Elliot, Jr., Edison Laboratory, Orange, N.J." The book contains 151 numbered pages, some of which are blank, followed by 7 unnumbered pages. Related material can be found in the Alexander Elliott, Jr., Papers and in the New Jersey and Pennsylvania Concentrating Works Records (Thomas A. Edison Papers, Part III (1887-1898)).
