picturesque, likened him to the great Caliph who in similar
fashion investigated Baghdad, and they nicknamed him Haroun al
Roosevelt. He had for his companion Jacob Riis, a remarkable Dane

and the haunts where Vice breeds like scum on stagnant pools, and

Roosevelt surprised a shirking patrolman on his beat, but his
purpose they all knew was to see justice done, and to keep the
officers of the Force up to the highest standard of duty.

One other anecdote concerning his experience as Police
Commissioner I repeat, because it shows by what happy touches of

policemen on the Force and ordered them to preserve order in the
hall and prevent Ahlwardt from being interrupted or abused. The
