Figure 5 Flying over Mayersville, NS looking south along the River Road (Hwy 1) approaching Vicksburg, 33 deg. and 19 min. at 9500′. There are many islands or
\nRiver channel bars along most streches of the river. And, ox bow lakes such as Lake Chotard and Eagle Lake shown here are on both sides of the river. They represent
\nformer channels of the river that have been cut-off as the river changes its course.<\/p>\n

\nThe southern part of the city of Vicksburg are in the upper right corner, area to the north of Natchez in the lower right.
\nOne problem I have with the District using Lt. Ross\u2019s 1790 (in blue) survey
\ndata is that Andrew Ellicott\u2019s trip and survey of 1798 showed the longitude reference data
\nused on maps before that time was up to 60 nm wrong. At that time land surveyor\u2019s were
\nusing star time to compute longitude positions. But, the accuracy of the measuring instruments
\nwere not very precise. Ellicott adapted the Jesuit astronomer Ferrar\u2019s method of making records of the positions of the
\nmoons of Jupiter on the evenings in which star time observations were made. Then.back from the trip these positions could be
\nused to determine more precisely the longitudinal location on earth. He and Ferrar knew from there study of Isaac Newton\u2019s
\ntheories of celestial mechanics that the value of the periods
\nof the multiple orbits of Jupiter\u2019s satellites were incommensurable and allowed this.
\n(This idea of how to tell star time using Jupiter\u2019s satellites actually goes back to Gallileo. More, historical comments
\nabout this can be found in his journal and historical information posted at
\nhttp:\/\/www.yhwhschofchrist.org main page.)<\/p>\n
