The scout disappeared. The five other men lifted their guns and resumed their rapid and noiseless progress. A moment later no sound broke the stillness save the thump of a mango, as it dropped lazily from its tree to the grass. So strange had been the apparition of these men, their dress had been so allied in colour to the soil, their passing had so little disturbed the solemn rumination of the forest, and their going had been so like a spectral dissolution, that a witness could have wondered if he dreamed. IV A small expedition had landed with arms from the United States, and had now come out of the hills and to the edge of a wood. Before them was a long-grassed rolling prairie marked with palms. A half-mile away was the military road, and they could see the top of a blockhouse. The insurgent scouts were moving somewhere off in the grass. The general sat comfortably under a tree, while his staff of three young officers stood about him chatting. Their linen clothing was notable from being distinctly whiter than those of the men who, one hundred and fifty in number, lay on the ground in a long brown fringe, ragged--indeed, bare in many places--but singularly reposeful, unworried, veteran-like. The general, however, was thoughtful. He pulled continually at his little thin moustache. As far as the heavily patrolled and guarded military road was concerned, the insurgents had been in the habit of dashing across it in small bodies whenever they pleased, but to safely scoot over it with a valuable convoy of arms, was decidedly a more important thing. So the general awaited the return of his practicos with anxiety. The still pampas betrayed no sign of their existence. The general gave some orders and an officer counted off twenty men to go with him, and delay any attempt of the troop of cavalry to return from the eastward. It was not an easy task, but it was a familiar task--checking the advance of a greatly superior force by a very hard fire from concealment. A few rifles had often bayed a strong column for sufficient length of time for all strategic purposes. The twenty men pulled themselves together tranquilly. They looked quite indifferent. Indeed, they had the supremely casual manner of old soldiers, hardened to battle as a condition of existence.
