In addition to the responsible position to which Gen. Cook was then elevated, he has also acted as deputy United States marshal for the district of Colorado, to which he was again appointed two years previous.
Gen. Cook is a born detective. When asked one day how he happened to follow this business, he replied: "It is natural. I can't help it; I like it." He never received a day's training from any other detective in his life, and yet from the very beginning he took rank with the best in the country. He stands to-day alongside of Mr. Pinkerton. Indeed, many of his exploits have far exceeded those of that justly-renowned officer in thrilling detail and startling climax. A hundred times in his life Dave Cook has been placed in positions where another man, under the same circumstances, less shrewd or less courageous, would have been shot dead in his tracks or eternally disgraced. But he was ever the right man in the right place as a detective, and it is owing to this fact that he has passed thirty-five years of detective and official life on the frontier without being killed. He possesses the essential qualities of mind and body necessary to become a successful detective in a degree rarely equaled in one man. He is both brave and discreet. He is never afraid to strike. No position appals him. Yet he is cool-headed and cautious and wastes no blows--ventures into no unnecessary danger, and knows how to reserve his strength until it is needed most. When the time comes to act he acts with decision and promptness, always accomplishes his purpose, no difference what the odds. He is an excellent judge of men. He knows how to select the best assistants, and he "spots" a criminal nine times out of ten. He knows when to talk and when to allow others to talk. He will listen half a day to a string of surmises entirely contrary to his own without interposing an objection, with the hope of getting a clue, where other men would spoil everything by airing their own opinions. His memory is excellent, his patience inexhaustible, his ability to put this and that together is unexcelled, his perception is sharp, his reasoning is clear, his courage is undoubted and his judgment is cool under all circumstances. Add to these faculties the fact that he always deals fairly with the public; that he never fails to protect his prisoners, and that he is a man of fine bearing, of splendid figure, a face of iron on which a smile appears at home, and you will discover the secret of Dave Cook's success as a detective and as an executive officer on the frontier in the Rocky Mountains.
