The bibliography of Watson's books on Philadelphia and New York requires a note. In 1830 he published, in one volume, Annals of Philadelphia, being a Collection of Memoirs, Anecdotes & Incidents of the City and its Inhabitants from the Days of the Pilgrim Founders. (Collation: Title, 1 p.; Copyright, 1 p.; Advertisement, pp. iii, iv; Preface, pp. v-vii; Contents, pp. viii-xii; Annals of Philadelphia, pp. 1-740; Appendix: containing Olden Time Researches & Reminiscences, of New York City, pp. 1-78.) In 1832 he published Historic Tales of Olden Time: concerning the Early Settlement and Advancement of New York City and State. In 1833 he published Historic Tales of Olden Time, concerning the Early Settlement and Progress of Philadelphia and Pennsylvania. In 1844 he published, in two volumes, Annals of Philadelphia and Pennsylvania, in the Olden Time; being a Collection of Memoirs, Anecdotes, and Incidents of the City and its Inhabitants, and of the Earliest Settlements of the inland part of Pennsylvania, from the Days of the Founders. This work was copyrighted in 1843, though the title page bears the date 1844. In the advertisement, which is dated July, 1842, Watson says: "The reader will please observe, that this work having been _closed in Manuscript_, in 1842, that therefore, all reference to any given number of years back, respecting things passed or done so many '_years ago_,' is to be understood as counting backward _from the year_ 1842" (p. xi). In 1846 he published Annals and Occurrences of New York City and State, in the Olden Time. In 1857 he published, in two volumes, Annals of Philadelphia and Pennsylvania, in the Olden Time. This edition contains some matter not in the 1844 edition. Finally, in 1877, Willis P. Hazard published, in three volumes, the Annals of Philadelphia and Pennsylvania, the first two volumes being identical with the 1857 edition of Watson's work, the third volume an addition by Hazard. The Uncle Sam story first appeared in the 1844 edition of Annals of Philadelphia and Pennsylvania (II, 335); and in the 1846 edition of Annals and Occurrences of New York City and State, in the Olden Time (p. 243), though the two accounts, as seen above, differ somewhat.
