Before Saturday a telegram came from Ann Hicks. She had arrived at Silver Ranch, conferred with Uncle Bill, and it was agreed that she should meet Ruth and the other girls at Yucca on the date Ruth had named in her letter. The addition of Ann to the party from the East would make it nine strong, including Miss Cullam as chaperon and Tom Cameron as “courier.”

Tom was to make all the traveling arrangements, and he went on to New York a day before Ruth and Helen started from Cheslow. There he had a small experience which afterward proved to be important. At the time it puzzled him a good deal.

It had been agreed that the party bound for Arizona should meet at the Delorphion Hotel. Therefore, Tom took a taxicab at the Grand Central Terminal for that hostelry. Mr. Cameron had engaged rooms for the whole party by telephone, for he was well known at the Delorphion, and all Tom had to do was to hand the clerk at the desk his card and sign his name with a flourish on the register.

The instant he turned away from the desk to follow the bellhop Tom noted a young man, after a penetrating glance at him, slide along to the register, twirl it around again, and examine the line he, Tom, had written there. The young fellow was a stranger to Tom. He was dressed like a chauffeur. Tom was sure he had never seen the young man before.

“Now, wouldn’t that bother you?” he muttered, eyeing the fellow sharply as he crossed the marble-floored rotunda to the elevators. “Does he think he knows me? Or is he looking for somebody and is putting every new arrival through the third degree?”

He half expected the chauffeur person to follow him to the elevator, and he lingered behind the impatient bellhop for half a minute to give the stranger a chance to accost him if he wished to.

But immediately after the fellow had read Tom’s name on the book, he turned away and went out, without vouchsafing him another glance.

“Funny,” thought Tom Cameron. “Wonder what it means.”

However, as nothing more came of it—at least, not at once—he buried the mystery under the manifold duties of the day. He met a couple of school friends at noon and went to lunch with them; but he returned to the hotel for dinner.

It was then he spied the same chauffeur again. He was helping a young lady out of a private car before the hotel entrance and a porter was going in ahead with two big traveling bags.
