The Constitution of the United States had been in force since 1788. Its provisions were little known to the general public and the almanac published it in full. The Constitution became the model for the constitutions of almost all the States, old as well as new. For this much credit was due to _Cramer’s Almanac_, at least so far as some of the Western and Southwestern States are concerned. More valuable than anything contained in the almanacs, from a local point of view, were the lists of marriages and deaths. Nowhere else are they to be found. No record of marriages or deaths was required to be made by either the municipality or the county. The church records were kept intermittently, and were imperfect. Few of the older families have records extending back to the beginning of the nineteenth century, and Cramer’s lists furnish the only accurate information on the subject. In 1804 he began publishing two kinds of almanacs, the “Common Almanac” and the “Magazine Almanac.” The latter contained somewhat more reading matter than the former. The almanacs were sold in large quantities both for local use and for distribution south and west of Pittsburgh. In the almanac for 1804 Cramer for the first time gave “a view of the manufacturing trade of Pittsburgh.” From that time forward, for the twenty-seven years that the publication of the almanacs was continued, much valuable local historical matter is to be found in their pages. The _Navigator_ was the result of an original idea of Cramer’s. He had been in Pittsburgh but a short time when he realized the necessity for a publication giving detailed information for navigating the Western rivers. He daily saw swarms of immigrants pass through the place, bound West and South, who lingered there attempting to learn, not only about navigating the rivers, but of the country to which they were bound. He proposed to furnish the information and set about collecting data for the purpose. He was venturing upon an almost uncharted sea.
