Bound volume---20 June 1842-12 September 1843

By 1842, funding from the U.S. Congress was essential if the now-impoverished Morse was to be able to build and prove his telegraph system. On February 23, 1843, his bill for appropriated funding passed in the House of Representatives by a slim majority of 89 to 83 (with 70 not voting), but obviously every vote was crucial. This annotated member list of the twenty-six states may have been used by Morse before, during, or after the vote. The symbol "O" is thought to indicate an assenting vote, "-" a dissenting vote, and ">" no vote.
