[Illustration:  A RIVER-FRONT HARMONY IN BLACK AND WHITE—­CHICAGO]

You stop to inspect a conservatory, and find yourself in a really marvelous landscape garden, set with statues, all under glass and heated, where the gaffers of Chicago are collected together to discuss interminably the exciting politics of a city anxious about its soul.  And while listening to them with one ear, with the other you may catch the laconic tale of a park official’s perilous and successful vendetta against the forces of graft.

And then you resume the circuit and accomplish many more smooth, curving, tree-lined miles, varied by a jolting section, or by the faint odor of the Stock-yards, or by a halt to allow the longest freight-train in the world to cross your path.  You have sighted in the distance universities, institutions, even factories; you have passed through many inhabited portions of the endless boulevard, but you have not actually touched hands with the city since you left it at the beginning of the ride.  Then at last, as darkness falls, you feel that you are coming to the city again, but from another point of the compass.  You have rounded the circle of its millions.  You need only think of the unkempt, shabby, and tangled outskirts of New York, or of any other capital city, to realize the miracle that Chicago has put among her assets ...

You descry lanes of water in the twilight, and learn that in order to prevent her drainage from going into the lake Chicago turned a river back in its course and compelled it to discharge ultimately into the Mississippi.  That is the story.  You feel that it is exactly what Chicago, alone among cities, would have the imagination and the courage to do.  Some man must have risen from his bed one morning with the idea, “Why not make the water flow the other way?” And then gone, perhaps diffidently, to his fellows in charge of the city with the suggestive query, “Why not make the water flow the other way?” And been laughed at!  Only the thing was done in the end!  I seem to have heard that there was an epilogue to this story, relating how certain other great cities showed a narrow objection to Chicago draining herself in the direction of the Mississippi, and how Chicago, after all, succeeded in persuading those whom it was necessary to persuade that, whereas her drainage was unsuited to Lake Michigan, it would consort well with the current of the Mississippi.

And then, in the night and in the rain, you swerve round some corner into the straight, by Grant Park, in full sight of one of the most dazzling spectacles that Chicago or any other city can offer—­Michigan Avenue on a wet evening.  Each of the thousands of electric standards in Michigan Avenue is a cluster of six huge globes (and yet they will tell you in Paris that the Rue de la Paix is the best-lit street in the world), and here and there is a red globe of warning.  The two lines of light pour down their flame into the pool which is the roadway, and you
