of one point in twenty-four hours. In the week 

 from the 24th to the 31st, we made, on an E.N.E. 

 course, only four hundred and eighty miles. Du- 

 ring this period the wind was moderate, and the 

 atmosphere filled with a dense haze, which made 

 everything damp. The barometer continued high 

 all the time, never falling below thirty inches, and 

 generally standing at 30,30. On the 31st, in lati- 

 tude 37° South, longitude 39° West, the wind 

 came in a squall to the S.W. This wind, like the 

 above, shifted from right to left, that is, from S.W. 

 to South, S.E., East, and so on to N.E. North, and 

 N.W., with a thick haze, heavy rain, thunder and 

 lightning, and the wind blowing occasionally in 

 strong gusts. After this it fell calm, in latitude 

 33° South. The breeze which succeeded was first 

 from the N.E. but, as usual, it drew to the north- 

 ward,with a thick haze, and a high swell from the 

 same quarter. In the evening of the 5th, the 

 wind, which was blowing fresh and steady from 

 North, shifted suddenly, and without any lull, or 

 other warning, to S.W., and blew for two hours so 

 hard, that we could barely carry triple reefed 

 topsails and reefed courses. This breeze in twen- 

 ty-four hours fell light, shifted round as formerly 

 to the South, S.E., East, and in latitude 28° South 

 to N.N.E. The only difference between this shift 

 of wind and those which preceded it, was the 

 absence of haze. It hung in the N.N.E. quarter, 

 blowing at times very fresh for three days, with a 

 high short swell. On the 10th it fell calm, after 

 which, on the evening of that day a breeze sprung 

 up from the S.W., and having made Round Island, 

 off Rio, early on the morning of the 12th, in very 



thick rainy weather, we ran in, and anchored, 

 after a passage of eighty-nine days from leaving 

 San Bias. 



RIO DE JANEIRO TO BAIIIA, OR ST. SALVADOR.

This passage, and that of his Majesty's ship 

 Doris, about the same time, serve to show how 

 uncertain the winds are on this coast. We sailed 

 in the Conway, on the 25th of November, met 

 with North and Noi'th -easterly winds off Cape 

 Frio, which obliged us to stand off for nine days, 

 at the end of which time we were one hundred 

 and fifty miles farther from Bahia than when we 

 first sailed. The wind now shifted to the south- 

 ward and S.W., with a high swell, and much 

 rain, and we reached our port on the 13th of 

 December. 



The Doris sailed on the 5th of December, ten 

 days after the Conway, and reached Bahia on the 

 12th, one day before us. 



It so happened that, immediately on leaving 

 Rio, she got the same southerly wind which carried 

 to the northward, and on the same day, but with 

 a less distance to run. At this time of the year 

 northerly winds certainly prevail, and such cir- 

 cumstances as the above do not arise above two 

 or three times in a season. As there are ample 

 published directions for navigating on this coast, 

 it is needless for me to say any more.
