DISTRIBUTIOX OF PLANTS. 



whole width of the Pacific, the wind came out adverse ; bringing thick 

 weather, and more or less rain throughout the greater part of the day. 



On the morning of the 30tli, Assumption was in sight; another 

 conical or pyramidal mountain, similar in outline, and also having 

 its summit concealed in clouds ; but clearing for a few moments, a 

 " crater" was seen by Mr. Dana and others ; and a " resemblance to 

 Stromboli" was also remarked. The elevation was estimated at " two 

 thousand" feet: but the ship kept at too great a distance for trees at 

 any time to be distinguished. 



Some rocks, called the " Mangs," were reported in sight from aloft; 

 but did not become visible from the deck. Being mere projecting 

 points, they indicated, that we had passed the limit of extensive coral 

 development, of wide-encircling coral-reefs. 



The monsoons are said to extend to the Ladrone Islands. So far as 

 our own experience goes, we here lost the regular trade-wind ; and 

 were afterwards sometimes baffled; but in general, were able to hold 

 our course Westward, as will appear by the following incidental 

 notices : 



The morning of the 31st was calm, with rather heavy rolling; but 

 in the course of the daj^, there was much wind, the sky being over- 

 cast. 



On the 1st of January, 1842, the wind was Southerly, and the ship 

 was driven to the Northward of her course. The surface of the ocean 

 rough, and at midnight much rain. 



On the 2d, the wind came from the Northward, boisterous, and un- 

 expectedly cool; so that many on board put on woollen clothes. 

 Tiie sky overcast much of the day. 



On the 3d, the wind continued from the Northward, and still cool. 

 The ship keeping close to the wind, and sailing rapidly. 



On the 4th, the weather was more pleasant, and the surface of the 

 ocean smoother. At night, a little cool, and the ship most of the time 

 lying-by. 



On the 5th, the weather was pleasant again. In the evening, a 

 little cool as before. 



On the 6th, the weather was warmer, and the wind lighter. 



On the 7th, there was a little more wind ; towards evening, coming 

 from the South; the weather continuing warm.
