Harry alighted a few stations up the line, and had lunch in a restaurant on a side street. Then he called a cab, and went directly to the Grandville Building.

It was shortly before three o’clock when he arrived at the office of Claude Fellows, on the fifteenth floor. He was ushered into the inner office.

Fellows was unusually congenial. He seemed satisfied with something that he had accomplished. He fairly beamed upon Harry.

“I have a job for you,” he said.

“That’s welcome news,” replied Harry.

Fellows read from a sheet of paper.

“Remember this?” he said. “Professor Arthur Whitburn. Lake Marrinack, Connecticut. He wants a young man — single — college graduate — to assist him in some experimental work. He was greatly pleased with the letter which you wrote him.”

“Which I wrote him?”

“I attended to that detail for you. I added a letter of recommendation from one of the officials of the Vesuvius Insurance Company. Mr. James Stohlmeyer, one of the vice presidents, had some very nice things to say about you.”

“Did you write that letter, too?” asked Harry, in admiration of the insurance broker’s versatility.
