 the island of Kauai, where you will obtain conveyances and proceed 

 to traverse the island in the following directions, viz. : you will 

 divide yourselves in three parties, and pursue the following routes. 



The first party, to take the eastern shore round to the north as far 

 as Halelea, following the courses of rivers, &c., and ascertaining their 

 extent. 



The second will proceed directly across the island, and join the 

 others at Halelea. 



The third party will proceed round the west side, in like manner, 

 following the rivers and streams, and rendezvousing at the same place. 



A sympiesometer is furnished, to be used in measuring heights, by 

 the party that crosses the centre of the island. Full reports will be 

 made to me on your return. 



Five days are allowed you for the excursion on Kauai, at the end 

 of which time you will join the Flying-Fish at Halelea. 



On your return here, Mr. Knox has orders to land you on the 

 western side of this island, at Waialoa, near Waimea Bay, the resi- 

 dence of Mr. Emerson; this will place you in a position to pursue 

 the researches on this island to advantag-e. 



The first party will take the southern route; the second, the 

 middle; and the third, the northern, returning to this place as soon 

 as circumstances will admit. 



It is beheved that the like number of days on this island will be 

 amply sufiicient. 



Your researches and inquiries will be directed principally to 

 botany, geology, zoology, mineralogy, natural resources, cultivation, 

 productions, late improvements, condition of the natives, supplies, 

 facilities for obtaining them, &c. I am, respectfully,
