"Captain Willard Glazier:
"Dear Sir:—I owe you an apology for not having earlier acknowledged your courtesy in sending me a copy of your remarkably interesting work 'Down the Great River.' Owing to illness and a variety of calls on my time, I had not an opportunity ere this of finishing the reading of it. I have no hesitation in saying that it is most interesting and instructive, especially where you so ably summarize the results of former expeditions, and where you describe in animated language the aim, course, and outcome of your own explorations. You have had an experience which has fallen to the lot of few travellers, and, in certifying the source of the Father of Waters, have rendered a great service to the cause of geographical discovery. The account of your voyage from the newly discovered Source to the Gulf of Mexico gave me much pleasure and information. The patience and endurance of the brave fellows who were with you, considering the distance, in canoes, is worthy of praise. Your own able management of the expedition is worthy of all commendation and of substantial and immediate thanks from the good men of your own wonderful country.
"Again I sincerely thank you for your handsome and most acceptable present.
"With sincere respect, I remain, dear sir,
"Yours faithfully,
"John Lovell.
