"It's gone," he muttered, "and here's something else coming back."
A few minutes later Glennie translated into English the words that had come to his sharp ears.

"Tell them," said Matt resolutely, "that she's three days out from the River Plate, and may be well below Cape Virgins by this time."
"Ach, lisden!" whispered Carl. "Pelow Cape Firgins—und here ve are to der nort', in Gallegos Pay."
"They say they will watch for her," reported Glennie, after sending the message and getting the answer.
Matt smiled grimly.
"Tell them, Glennie," said he, "to try and pick her up before she gets around the Horn."
