APPENDIX. 3S1 
" The Russian Vice-Admira], Krusenstern, transmitted to the De- 
partment memorandums relating to the objects of this Expedition, 
together with the most approved 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 contribution of 
this distinguished navigator, will essentially contribute to the success 
of an enterprise in which he takes so deep an interest. It being 
considered highly important, that no journal of this voyage, either 
partial or complete, should be published, without the authority and 
under the supervision of the government, 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, draw- 
ings, 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 efficient measures to prepare 
and preserve all specimens of natural history that may be collected ; 
and should any opportunity occur for sending them home by a vessel 
of war of the United States, also copies of information, duplicates of 
specimens, or any other materials, you may deem important to pre- 
serve from future accident, you will avail yourself 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 pro- 
hibiting 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. 
" It is believed that the officers under your command require no 
special advice or direction from this Department. Bearing in mind, 
as they no doubt will, that the undertaking in which they are about 
assisting to accomplish, is one that necessarily attracts the attention 
of the civilized world, and that the honour and interest of their 
country are equally involved in its results, it is not for a moment 
doubted, but that in this, as on all other occasions, they will so 
conduct themselves as to add to the reputation our navy has so justly 
acquired at home and abroad.
