everywhere passable for vehicles, the requisite bridges having 

 been constructed. It is not a road of much importance, as all 

 heavy and bulky goods to be conveyed in its direction are, of 

 course, taken by water. 



The second has of late years received considerable attention; 

 bridges have been made, embankments thrown up, &c. There 

 is a great and rapidly increasing traffic along it ; many thousand 

 pounds' worth of salt being annually taken up it to the interior. 



The third has as yet been only partially opened, and is not 

 available for carts. Large quantities of cotton, paddy, &c, 

 are, however, brought down by it to the coasts, and the natives 

 living on the borders of this and the Northern Province inform 

 me that they derive much advantage from it, even in its present 

 imperfect state.

 had lately the honor to submit to the Society, and deem it 

 unnecessary to state more than merely that, from observations 

 continued for one year (from 1st August, 1847, to 31st July, 

 1848) and registered at 9 a.m., at noon, and at 3 p.m., it 

 appears that :—

The highest mean of any month was in March 85*796
