Chap. II. AVIXDS OX THE TAPAJOS. 149 



Senhor Cypriano was a pleasant-looking and extremely 

 civil young Mameluco. He accompanied us, on the 

 nio'ht of the 28th, five miles down the river to Point 

 Jaguarari, where the man lived whom he intended to 

 send with me. I was glad to find my new hand a 

 steady, middle-aged, and married Indian ; his name was 

 of very good promise, Angelo Custodio (Guardian Angel). 

 After the 26th of September the north-west day- 

 breeze came every morning with the same strength, be- 

 ginning at ten or eleven o'clock, and ending suddenly at 

 seven or eight in the evening. The moon was in her 

 third quarter, and we had many successive days and 

 nights of clear, cloudless sky. I believe this wind to be 

 closely connected with the easterly trade-wind of the 

 main Amazons ; indeed, to be the same, reflected from 

 the west after the land-surface in that quarter has been 

 cooled by it to a much lower point than the sun- 

 heated surface of the stagnant Tapajos. The wind 

 always arose in the morning after the air in the direc- 

 tion of the north-west had been further cooled by ra- 

 diation of heat during the nisfht ; and it ceased in the 

 evening, when the equilibrium of temperature between 

 the Tapajos and the Amazons had become restored. The 

 light land breeze from the east which always began to 

 blow soon after the strong north-wester ceased, is attri 

 butable in like manner to the wooded surface of the 

 land being then cooler than the air on the river. The 

 terral lasted generally from 7 until 11 p.m., but after 

 midnight it usually veered gradually to the north-east, 

 and blew rather freshly from that quarter towards 

 sunrise.
