Aug. 1829. GuIA NARROWS—PECULIAR TIDES, 265 
animal, and noticed a harbour opposite, in which they anchored. 
They had such trouble in getting to the northward, that this 
day’s run, though only eighteen miles, was a cause of much 
satisfaction. 
On the 20th, at daylight, the boats were employed around 
the anchorage, and at nine o’clock the vessel was underweigh, 
and working to the northward, although it rained hard then, 
as well as throughout the whole day, after beating until the 
evening, she anchored on the west shore. 
Constant rain fell through the whole night, and during the 
21st ; it was therefore impossible to make any progress to the 
northward. 
On the 22d the Adelaide weighed, and the weather being 
calm, was towed during the whole forenoon. At noon a south- 
erly wind sprung up, and by the evening she was in the Guia 
Narrows (of Sarmiento). They tried for anchorage in Unfit 
Bay, conceiving it to be Sarmiento’s Port Ochavario; but 
none being found, the vessel was towed into a cove, and securely 
moored. 
Next day the boats surveyed the Guia Narrows. Although 
long, they did not appear hazardous to pass, for the tides are 
not very rapid. The ebb tide runs to the northward, but at 
the south entrance of the San Estevan Channel, the ebb sets to 
the southward ; which difference in direction, within so short 
a distance, is extraordinary, and difficult to account for without 
knowing more of the coast. Certainly there is a meeting of 
tides between the two entrances; probably, all the land west- 
ward of San Estevan is a collection of large islands, and water 
flows into this channel, from the Pacific, through many open- 
ings, which may be the cause of this peculiarity. 
24th. With light breezes from the eastward, the schooner 
weighed and stood through the Narrows; passed Point San 
Juan, and continued along the eastern shore of Concepcion 
Strait to Guard Bay, where she was moored, 
25th. Rainy weather until near noon, when the boats were 
employed. 
On the 26th the schooner was towed out, and, as it was calm,
