They rode on and when the tramp of feet got louder, Marston asked: "Do the cazadores often drill in the dark?"

"Once they scarcely drilled at all," said Don Luis, laughing. "However, since Ramon Larrinaga became the President's friend they drill them much, with German officers in command. Recently the drilling has got harder and one wonders why this is and whether it means something. All the same, I am a supporter of the President's and if he is satisfied—"

The measured tramp was now very close, and the creak of leather and rattle of straps and slings came out of the gloom. Marston thought he could hear the labored breath of men toiling up hill. Then a hoarse challenge rang out and his horse plunged across the road.

"Hold him!" said Wyndham sharply, and two or three men with glittering bayonets came into the moonlight that shone between the trees.

"A picket, or advance guard!" Wyndham resumed. "Get down, Bob. You mustn't let the brute go!"

Marston's horse reared and tried to turn from the shining steel, but he got his foot out of the awkward stirrup and swung himself from the saddle. The others dismounted and the soldiers led them off the road and then stood on guard.

"I do not know if we are arrested," Don Luis remarked with a shrug. "One must use patience; but I am not without some influence and expect apologies when the officers arrive."

When he had quieted his horse Marston lighted a cigarette and leaned against a tree. For a few yards the moonlight shone upon the road and when the first fours of the leading platoon crossed the illuminated belt he was surprised. The cazadores were short, dark-skinned men. Their sloped rifles wavered at different angles, and their march was slouching, but they carried complete field equipment; pouches, mess-tins, tools and bandoliers. It was the first time he had seen the republican soldiers in regular marching order.

"Your government has been extravagant," he said to Don Luis.

Don Luis spread out his hands. "It is these Germans! Somebody will have to pay and the country is poor. Perhaps it is well to pay the soldiers, but one need not spend money on equipment until there is risk of war."
