 To the Officers of the Hudson's Bay Company'' s Service. 



Gentlemen : Having been applied to by tbe Secretary of the 

 S-iiithsonian Institution of Washington, for permission to invite 

 ,f!he assistance of the Company's officers in conducting observa- 

 tions, having for their object the development of the physical and 

 natural history of the northern part of this continent, I have very 

 cheerfully acceded to the request, and take the present means of 

 commending the object in view to your favorable consideration. 



You are well aware of the desire of the Company to promote 

 the interests of science by all the legitimate means in its power. 

 In the present case, where so much may be done by systematic 

 and conjoined action, over a widely extended territory, it will be 

 gratifying to learn that information and materials of a valuable 

 character have been supplied from the stations of the Company, 

 and by the industry of its officers. 



The accompanying circular and instructions, from Professor 

 Henry, will explain more fully the objects of the Institution, and 

 will be found to embrace all necessary information for your 

 guidance. 



I am, gentlemen. 



Your obedient servant, 



G. SIMPSON.
