The clock was 4' 5" too fad mean time when the obfervations on the 

 tranfit of ^ were maJ;, and the equation t'f time 3' 44" additive to the 

 mean time, the difference therefore between 4' 5" and 3' 44" being deduct- 

 ed from the obfervations will give die apparent times.

It was mv orisiinal intention to have taken charts of 

 the fouthern parts of all the rivers interfecled hy the 3 ill 

 degree of N. lat. and falling into the gulf of Mexico be- 

 tween the Miffiffippi, and St. Marks : But having no bu- 

 finefs up or down the Palkagola, (which is a large river 

 and navigable for boats of burden many iniles above the 

 boundary), it was omitted. — The Chattahotha, or as it is 

 fometimes called the Appalachicola, is a river of more 

 importance than the former, and a map of it from the 

 boundary to its mouth was a defirable object ; but owing 

 to the precipitate manner we had to leave the country in 

 confequence of the hoftile difpofition of the Indians, and 

 defcending the river partly in the night, it was impoffible 

 to take a fketch of it with any tolerable degree of accu- 

 racy. — About 4 minutes of a degree north of the entrance 

 of its weftern branch into St. George's Sound, I found the 

 latitude to be about 29° 46' 51' N. — At the fame place

* The clock was well faftened to a poft fet 34- feet in the ground, but 

 being neitlier covered, nor furrounded by any building, and feveral hun- 

 dreds of Indians in our camp, fome individuals of whom were frequently 

 leaning againft the poft, (though admonifhed to the contrary), which cir- 

 cumftance might produce a fmall in-egularity in the going of the regulator.
