ell stared, for the fraction of an instant. One thought came to him, and was checked. The Trade does not exist, anywhere. The Trade would not help. And murderers are always duly handed over when the Government of the United States is requested politely to do so by another nation. Always. And so far as the whole civilized world was concerned they were murderers. Even the employees of the flying field who were not subject to The Master would swear to the strictly accurate story of their escape together.

"It is just scandalous enough and horrible enough," said Bell quietly, "to be reprinted everywhere as news. You're right. We haven't any friends. We're up against it. And so I think we'll have to hunt down and kill The Master. Then we'll be believed. And there are just two of us, with what weapons we have in our pockets, to attack. How many thousands of slaves do you suppose The Master has by now?"

CHAPTER VII

he sun was sinking slowly when the plane appeared above the valley. There was only jungle below. Jungle, and the languid river which now flowed sluggishly into a wide and shallow pool in which drowned trees formed a mass of substance neither land nor marsh nor river. The river now contracted to a narrow space and showed signs of haste, and even foaming water, and then again flowed placidly onward, sometimes even a hundred yards in breadth. Shadows of the mountains to the west were creeping toward the opposite hill-flanks, darkening the thick foliage and sending flocks of flying things home to their chosen roosts.

The sound of the plane was a buzzing noise, which grew louder to a sharp drone as it seemed to increase in size, and became a dull monotonous roar as it dipped toward the waters of the stream. It floated downward, very gently, and circled as if regarding a certain spot critically, and resumed its onward flight. Again it circled, anxiously, now, as if the time for alighting were short.

It seemed to hesitate in mid-air, and dived, and circled up-stream and came down the valley again. It sank, and sank, lower and lower, until the white of its upper wings was hidden by the tall trees on either side.
