"It looks pretty small compared to some of these that we've gone through."

But as the morning passed they wearied at last of looking at the scenery, varied as it was, and toward mid-afternoon they began to be impatient for a sight of Chicago. When, at last, the train began to roar through the suburbs of the Windy City, as a friendly porter called it when they had failed to understand his reference to it as "Chi," they felt a mounting excitement. But the train rushed in past seemingly endless rows of houses, then past miles of industrial buildings overhung with a cloud of murky smoke, until they thought the center of the city would never be reached.

The journey came finally to an end. Their porter was on the platform with their grips, they tipped him for his services during the trip and made their way down the crowded pavement, through the gates into the concourse of the enormous station. Here they gazed about in frank wonderment at the bustling hordes of people, all intent on their own affairs, moving to and from the trains. The constant sound of shuffling feet, buzzing voices, clanging bells, all the varied noises of a great railway station, sounded like the roar of the ocean in their ears.

They made their way outside and clambered into a waiting taxi, directing the driver to take them to the hotel their father had mentioned in his telegram. In a short time the car drew up at the entrance, after a brief ride through crowded, noisy streets that made the main street of Bayport seem like a country lane on Sunday afternoon by comparison. A bellboy seized their grips and the boys presented themselves at the desk.

The clerk glanced at their names after they had signed.

Feeling highly important at being referred to as "gentlemen" and at having a bedroom actually reserved for them in a hotel of such grandeur, the Hardy boys followed a military-looking bellboy to the elevators, whence followed a swift ascent to the eighth floor. Then down wide, silent corridors to their room, a substantial, bright and airy room with bath. It was all a revelation to the lads, who had never been in a big hotel before, and when they looked out the big windows down on the thronging life of the city streets below they were excited beyond measure.

"First of all, we'll read dad's letter," said Frank. "These are the instructions he promised, I suppose."

He opened the envelope and read:

"My Dear Boys:
