“Thank you, doctor—much obliged to you.”

“Now, Resident, I must beg you to excuse me. I must be off at once as I have a number of visits to pay. Good-bye, sir—good-bye, Verstork.”

“No excuse required, doctor,” said van Gulpendam, “don’t let me detain you; good-morning!”

As soon as the medical officer had disappeared van Gulpendam turned to Verstork and said:

“You heard that—didn’t you, Mr. Verstork?”

“Oh, yes, I heard it; but my conviction is not the least shaken.”

“It is not?”

“No, Resident.”

“Well, for all that,” said van Gulpendam, airily, “I advise you to heave to.”

“To heave to? I don’t understand you,” said Verstork, though all the time he understood perfectly.
