 fe'lR, 



After leaving the Straits of Sunda, you will be governed by the 

 following instructions, viz. : 



You will proceed to the westward across the Indian Ocean, passing 

 five or six hundred miles to the southward of the island of Panaw, 

 double the Cape of Good Hope, and visit the island of St. Helena, where 

 you will lose no time in filling up with water, and proceed from thence 

 to Rio de Janeiro, at which place you will make experiments for dip 

 and intensity, on the island of Enxados, and take on board a sufficient 

 quantity of bread for the passage to New York. 



When you arrive at New York, you will cause all journals, memo- 

 randums, remarks, writings, drawings, sketches and paintings, as well 

 as all specimens of any kind, to be delivered to you ; which, together 

 with your own journal, you will have carefully boxed up and sealed in 

 the presence of two commissioned officers; marked Exploring Expe- 

 dition, and hold them subject to my orders. 



On your arrival at New York, you will find orders from me, or, if I 

 should not have arrived, you will report by letter to the Honourable 

 Secretary of the Navy, sending him a copy of this order. 



You are supplied with Six's self-registering thermometer, with which 

 you will obtain the temperature daily, at the depth of one hundred 

 fathoms, when your morning sights are taken ; at which time you will 

 note in tables the latitude and longitude, the current (velocity and 

 direction), masthead temperature, deck temperature, and temperature 

 at the depth of one hundred fathoms, and at the surface. 



You will examine all shoals, banks, and positions marked "doubt- 

 ful," that may lay in or near your track. 



At St. Helena, you will leave letters informing me of your proceed- 

 ings, and you will lose no time in making your way to your final port 

 of destination, as it is all-important you should reach the United States 

 at as early a day as possible. 



On dropping your anchor in New York Bay, you will pay to each 

 of your crew ten dollars, and suffer them to leave the vessel at once, 

 as their time will have expired ; and retain only as many as will volun- 

 teer to take charge of the brig. 



In the event of my arriving before you, orders will meet you for the 

 disposition of the journals, &c, of which you will take particular care,
