Here's some historical positional info for Small's/Smalls Rock lighthouse: I checked Bowditch 1826, 1842, 1849 and the position listed in these editions is 51d 45'N 5d 36'W. That's very likely the position known to Sumner. In the 1868 edition the position is about three miles away: 51d 43'N 5d 40'W. In the 1883 edition, which is when the US Navy took over and substantially re-wrote the book, the position is the same but more precise: 51d 43' 14"N 5d 40' 9"W. BTW, in all of these it's listed as "Small's" (possessive). In the 1918 edition of Bowditch, the position for "Smalls Rocks: lighthouse" (no longer possessive) is listed as 51d 43' 15"N 5d 40' 15"W. According to various web sites, the first Smalls Rocks light was built in 1773 and stood until 1858. It consisted of an octagonal cabin standing on nine massive oak posts. A new lighthouse was built from 1859-1861. It still stands (apparently), and it is a circular stone tower with a flared base. There's a photo of it here: http://jharadie.tripod.com/lights/lighthouse2/smalls_light.jpg with its former paint scheme. Here's a fairly detailed history of the lighthouses: http://www.trinityhouse.co.uk/interactive/gallery/smalls.html Are there enough rocks out there to build the later lighthouse a few miles away? -FER 42.0N 87.7W, or 41.4N 72.1W. www.HistoricalAtlas.com/lunars
