All the calculations in Houghton's 1807 almanac, except those for the rising and setting of the sun and the length of the day, duplicate those in the Newhampshire, Massachusetts and Vermont almanack for 1807, astronomical calculations by Gilbert Graves (Walpole, N.H.), although a few of the calculations in Graves are not paralleled in Houghton. Copies of letters by Graves, accompanied by a photostat of letters by Isaiah Thomas to or concerning him, are in the American Antiquarian Society's manuscript collection. These indicate that Graves calculated Isaiah Thomas Jr.'s Town & country almanack for 1813 to 1815, the 1813 issue in collaboration with Houghton. The calculations in Thomas' almanacs for several years previous are identical in part or almost entirely with those in Houghton's. All these circumstances suggest a collaboration between Graves and Houghton, on both the Houghton and Thomas series of almanacs, from at least 1807 to perhaps 1813. The title pages of Houghton for 1807-1813 have the phrase, "Astronomical part by Asa Houghton." All others before and after these dates have the phrase, "By Asa Houghton." The wording of the authorship phrase is not as suggestive as the alteration in it.

Two issues noted, in which leaf C6 varies. One issue has "Courts in the state of Rhode-Island," "Useful table, for reducing shillings and pence into cents & mills," "Cowper to Samuel Rose, Esq." and four anecdotes. Another issue has "Courts in the state of Rhode-Island," "Courts in the state of New-Hampshire," "Cowper to Samuel Rose, Esq." an anecdote, and the "Useful table ..."
