Terry, whose thoughts were following the same line as were Arden’s, decided, if they reached Cedar Ridge and found no trace of Sim, that it would be best at once to telephone from college to the parents of the missing girl and ask for advice.

There was a milling throng on the platform of the Thirty-third Street tube station on one side of which trains left for Jersey City and Newark, and on the other side for Hoboken and thence to Cedar Ridge. As well as they could, Terry and Arden peered through the crowd for Sim. But she was not to be seen, and the hope thermometer in their hearts went nearer the zero mark.

The train was crowded, and it was almost impossible for Arden and Terry to converse above the noise. It didn’t matter. They had nothing of interest to talk about, now. They looked anxiously at each other. Were they deserting Sim? Or rather, were they not showing real confidence in her? She must be safe! The excitement of the travel was helping to cheer her chums.

When Hoboken terminus was reached and the crowds poured out as they had flowed in, once more the two sought anxiously among the many faces. But though there were scores of their fellow students hurrying to catch the next Cedar Ridge train, Sim was not among them.

“She may be on the platform waiting for us,” suggested Terry with a hope she did not feel.

“Maybe,” Arden murmured prayerfully.

They almost stumbled up the concrete steps in their haste. The ramp, from the iron gates of which departed many trains for many places, was another place of milling crowds outside the station. A man in a portable information booth was answering questions in a very patient manner.

By listening, without asking, Terry and Arden learned from which track their train departed and the time. They had a few precious minutes left.

“Let’s look around out here and then go inside,” proposed Terry, who was lugging along Sim’s bag with her own.

“She isn’t here,” Arden sighed, after a search. “Let’s go inside the station.”
