xxx INSTRUCTIONS. 



kindred pursuits, whose equal dignity and usefulness should insure equal ardour 

 and industry in extending their bounds and verifying their principles. 



As guides to yourself and to the scientific corps, the Department would, 

 however, direct your particular attention to the learned and comprehensive 

 Reports of a committee of the American Philosophical Society of Philadelphia, 

 the Report of a Committee of the East India Marine Society, of Salem, Massa- 

 chusetts ; and to a communication . from the Naval Lyceum of New York, 

 which accompany, and are to be regarded as forming a part of these instruc- 

 tions, so far as they may accord with the primary objects of the Expedition, 

 and its present organization. You will, therefore, allow the gentlemen of the 

 scientific corps the free perusal of these valuable documents, and permit them to 

 copy such portions as they may think proper. 



The Russian Vice- Admiral Krusenstern, has transmitted to the Department 

 memorandums relating to the objects of this Expedition, together with the most 

 improved charts of his atlas of the Pacific Ocean, with explanations, in three 

 volumes. These are also confided to your care ; and it is not doubted that the 

 friendly contributions of this distinguished navigator will essentially contribute' 

 to the success of an enterprise in which he takes so deep an interest. 



You will prohibit all those under your command from furnishing any persons 

 not belonging to the Expedition, with copies of any journal, charts, plan, memo- 

 randum, specimen, drawing, painting, or information of any kind, which has 

 reference to the objects or proceedings of the Expedition. 



It being considered highly important that no journal of these voyages, either 

 partial or complete, should be published, without the authority and under the 

 supervision of the government of the United States, at whose expense this 

 Expedition is undertaken, you will, before you reach the waters of the United 

 States, require from every person under your command the surrender of all 

 journals, memorandums, remarks, writings, drawings, sketches, and paintings, 

 as well as all specimens of every kind, collected or prepared during your 

 absence from the United States. 



After causing correct inventories of these to be made and signed by two 

 commissioned officers, and by the parties by whom they were collected or 

 prepared, you will cause them to be carefully sealed by the said officers, and 

 reserved for such disposition as the Department may direct. 



You will adopt the most effectual measures to prepare and preserve all 

 specimens of natural history that may be collected, and should any opportuni- 

 ties occur for sending home by a vessel of war of the United States, copies of 

 information, or duplicates of specimens, or any other material you may deem 

 it important to preserve from the reach of future accident, you will avail your- 

 self of the occasion, forwarding as frequently as may be done with safety, 

 details of your voyage and its most material events, at the same time strictly 

 prohibiting all communications except to this Department, from any person 

 attached to the Expedition, referring to discoveries, or any circumstances 

 connected with the progress of your enterprise.
