General Directions to he observed during a VoyageJ^ 

 The towing-nets should be kept overboard whenever it 



is practieabie, and the dredge should be used persever- 



ingly in soundings. 



o 



The anchor sliould be inspected as soon as it arrives 

 at the surface, especially if the holding ground be mud. 



Th^ finest sheik have been lifted on the flukes of anchors. 

 The cable should also undergo an examination. 



Let the arming of the lead be narrowly observed, and 

 let the men have orders to preserve anything that may be 

 sticking to the arming, the lead itself, or the lead line- 

 Floating masses of sea*weed, especially sargasso, should 

 be carefully searched ; and if one of those tangled 

 natural rafts, which are often carried adrift from great 

 rivers, sliovild be seen, it should be examined minutely, 

 and the animals, plants^ and seeds which it may be trans- 

 porting to colonize some newly-formed island, should be 

 preserved, if possible, or, at all events, accurately noted. 

 Whenever a new marine sp<^cies, or one whose habits 

 are unknow^n, is obtained, it should be placed in sea- 





ter, and, if practicable, a drawing should be made of 



it while yet alive, with a note statin 





whether it is gre- 

 or solitary — phosphorescent or not — and giving 



the locality, the temperature, the state of the weather, 

 the depth of water^ and the time where and w^hen it ., 

 captured. The sea w^ater in which living marine animals 



kA>*^ 



are confined 



kJ 



hould be often changed 



for it speedily 



becomes unfit for life.
