Gladsden regarded the tall mass with some uneasiness as he approached sufficiently near to measure its dimensions and examine the emblems stained, rather than painted, on the alabaster base stone. A colossal half human, half bovine head, armed with terrible horns, and showing long angular teeth in a ferocious grin, was prominent among these designs.

All was so still that he hesitated to wake the echoes with a more or less tolerable imitation of the wildcat, to which no response came, or if from a distance such was raised, the approaching thunderpeals overcame it.

He boldly plunged into the doorless passage, the way to which had been to a more wary man suspiciously free from brambles.

A smell of smoke, and even of tobacco smoke, he thought, overcame that of damp earth.

The only light was that which the doorway admitted, but several plates of mica, backed rudely with metal, which time and damp had tarnished, made the interior a little less sombre by their dull reflections. A ladder of wood, all the fastenings of rawhide, could be distinguished climbing like a twin snake up the wall; on high a grayish eye seemed to look unwinkingly down: it was the light oozing in at the gap at the top.

There were red streaks on the wall: paintings in red pipe clay partially effaced, or mementoes of slaughter, just as the spectator chose to believe or fancy.

At the moment, the intruder was chiefly interested in the charcoal under his feet, almost warm, certainly so fresh that he concluded that others than he chose it for a refuge under stress of weather, no doubt Master Pepillo's congeners.

Less courageous, he would have shrunk away without pondering over the nature of his predecessors, possibly regular hosts of this lugubrious domicile of owl and vulture.

Convinced that he was, for the time being, the sole tenant, Gladsden resolved, however, to explore the portion unrevealed. To his hands and feet the ladder presented no obstacle, and he ran up the rough rattlings swiftly, spite of fatigue. It brought him into a species of manhole under the roof, close to the gap, and yet shielded from its draft by a jutting piece of wall.

"This will do," thought he, finding it dry and clean; "I will kill a brace of birds frightened into stupidity by the oncoming storm, roast them on that charcoal, and bring them up here for supper. If the robbers surprise me, I will maintain that I was merely killing time before the arrival of lieutenant Ignacio, and claim that gentleman's friendship by reason of my charge from his brother. If I am interrupted, I shall pull up the ladder, in trust that it will come free, and sleep here, safe from prowling beasts and serpents."
