The "bunting-tosser," with his telescope glued to his eye, called out the letters of a string of bunting that rose to the "Trone's" mast head. His mate, having written various cabalistic signs on a signal-pad (the numbed state of his hands prevented his making any legible letters), hurried off to consult the International Code Book.. "Is it necessary for me to heave-to?" was the significance of the Jane's signal. "I have been examined twice already." "Then three for luck, you bounder!" chuckled Tressidar. "Signalman, hoist the International 'I D'." I D--signifying the peremptory order, "Heave-to or I will fire into you," was a message not to be ignored. Patches of foam under the vessel's counter and streaming for'ard past her water-line announced that her engines were going astern in order to check her way. "Like a trip in the boat, Mr. Barcroft?" asked Tressidar, as he noticed the flight-sub regarding the boarding party with studied interest. "Very good; you may learn a few tricks of the trade." With her guns trained upon the suspect--for experience had taught British officers that Hun raiders do not scruple to sail under neutral colours--the "Antipas" circled round the now stationary "Trone," the while maintaining a sharp look-out for hostile submarines that have a habit of keeping in touch with ships liable to examination much in the same manner as a pilot fish attends upon a shark. "She looks quite a mild cuss," observed the sub of the duty boat to Billy, "but one never knows. A few weeks back I was boarding some old hooker. Pitch dark night and raining like blue blazes. We'd just run alongside when the blighters heaved something overboard--looked like an elephant by the size of it. Anyway, it missed us by a yard and gave us all a sousing, which we didn't mind as we were pretty wet already. Then she pushed off for all she was worth, thinking that our skipper would have to moon about and pick us up. He did," added the young officer grimly, "--after he had squared accounts with the brute--another would-be 'Moewe.' A torpedo at five hundred yards settled her. In bow!" The bowman boated his oars, and balancing himself in the plunging bows of the little craft, dexterously secured the end of a coil of rope that was thrown from the "Trone's" deck. Up the swaying "monkey-ladder" swarmed the British officers and men, and gaining the Dane's deck were received by the dapper, clean-shaven skipper. "Of course, of course, I understand," replied the Dane in excellent English when the sub apologised for having had to compel him to heave-to. "Our papers are here. We are from Esbjerg to Newcastle with passengers and general cargo." "Very good," replied the sub in charge of the boarding-party. "I'll have a squint at your papers. Say, Barcroft, would you mind examining the passengers? Try a few words of German on 'em unawares. That generally fetches the black-listers."
