 The 21st. From the commencement 

 voyage to this day, we had, reckoned from the 

 meridian of Greenwich, gone 360 degrees from 

 E. to W., and, consequently, lost one day ; I there- 

 fore advanced the 21st to the 22d, and Tuesday 

 was made Wednesday. 



The 24th. We saw the island of St. Helena 

 at a distance of 50 miles in N. W. I resolved to 

 remain here one day, that the Russian commis- 

 sary, Count Balleman, might have an opportunity 

 of sending letters by me to his country, and ap- 

 proached towards evening an English brig of war, 

 which cruises here, and strictly examines all ships 

 going to St. Helena. The officer came on board ; 

 but before he entered my cabin cocked a pistol, 

 which he had concealed in his sleeve : he adviged 

 me to remain during the night near the island, that 

 they might announce our arrival, at day -break, by 

 the telegraphs, and that we could then proceed to 

 James Town.
