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 

 21 st ; 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. Bainy weather until near noon, when the boats were 

 employed. 



On the 26th the schooner was towed out, and, as it was calm,
