 Sir : Herewitli is respeotfiilly trausiuitted ;i narrative account of the explorations of the 

 Kowak River, Alaska, together with photographs and sketches made by me in that region. 



The report on the natural history is under preparation by Mr. Charles H. Townsend, and 

 a copy will be delivered to you as soon as completed. 



Ifeel sure you will understand the difficulties under which I have labored in attempting 

 to compile the (lata which we have been at such pains to collect, and in consequence deem it 

 almost unnecessary to a.sk your indulgence for its many imperfections. 



I desire to place myself on record as being under great obligations to you for every favor 

 tliat has been shown to me in the matter of the e.Kplorations. Much, if not all. of tlie lionor 

 of being the pioneers at the headwaters of the Kowak is due directly to your forethought, and 

 the example you set me of well-.sustained and indomitable energy. I thank ycm for this and 

 for all your kindness, and beg to subscribe myself. 



Very truly and gratefully, your obedient servant, 



JOHN C. CANTWELL,
