Brill nodded abstractedly, hardly heeding. Of all the continent of North America there is no section so haunted by tales of lost or hidden treasure as is the Southwest. Uncounted wealth passed back and forth over the hills and plains of Texas and New Mexico in the old days when Spain owned the gold and silver mines of the New World and controlled the rich fur trade of the West, and echoes of that wealth linger on in tales of golden caches. Some such vagrant dream, born of failure and pressing poverty, rose in Brill's mind.
Aloud he spoke: "Well, anyway, I got nothin' else to do and I believe I'll dig into that old mound and see what I can find."
The effect of that simple statement on Lopez was nothing short of shocking. He recoiled and his swarthy brown face went ashy; his black eyes flared and he threw up his arms in a gesture of intense expostulation.
"Dios, no!" he cried. "Don't do that, Senor Brill! There is a curse —my grandfather told me—"
"Told you what?" asked Brill.
Lopez lapsed into sullen silence.
"I cannot speak," he muttered. "I am sworn to silence. Only to an eldest son could I open my heart. But believe me when I say better had you cut your throat than to break into that accursed mound."
"Well," said Brill, impatient of Mexican superstitions, "if it's so bad why don't you tell me about it? Gimme a logical reason for not bustin' into it."
"I cannot speak!" cried the Mexican desperately. "I know!—but I swore to silence on the Holy Crucifix, just as every man of my family has sworn. It is a thing so dark, it is to risk damnation even to speak of it! Were I to tell you, I would blast the soul from your body. But I have sworn—and I have no son, so my lips are sealed forever."
"Aw, well," said Brill sarcastically, "why don't you write it out?"
Lopez started, stared, and to Steve's surprise, caught at the suggestion.
"I will! Dios be thanked the good priest taught me to write when I was a child. My oath said nothing of writing. I only swore not to speak. I will write out the whole thing for you, if you will swear not to speak of it afterward, and to destroy the paper as soon as you have read it.
"Sure," said Brill, to humor him, and the old Mexican seemed much relieved.
"Bueno! I will go at once and write. Tomorrow as I go to work I will bring you the paper and you will understand why no one must open that accursed mound!"
And Lopez hurried along his homeward path, his stooped shoulders swaying with the effort of his unwonted haste. Steve grinned after him, shrugged his shoulders and turned back toward his own shack. Then he halted, gazing back at the low rounded mound with its grass-grown sides. It must be an Indian tomb, he decided, what with its symmetry and its similarity to other Indian mounds he had seen. He scowled as he tried to figure out the seeming connection between the mysterious knoll and the martial ancestor of Juan Lopez.
Brill gazed after the receding figure of the old Mexican. A shallow valley, cut by a half-dry creek, bordered with trees and underbrush, lay between Brill's pasture and the low sloping hill beyond which lay Lopez's shack. Among the trees along the creek bank the old Mexican was disappearing. And Brill came to a sudden decision.
Hurrying up the slight slope, he took a pick and a shovel from the tool shed built onto the back of his shack. The sun had not yet set and Brill believed he could open the mound deep enough to determine its nature before dark. If not, he could work by lantern light. Steve, like most of his breed, lived mostly by impulse, and his present urge was to tear into that mysterious hillock and find what, if anything, was concealed therein. The thought of treasure came again to his mind, piqued by the evasive attitude of Lopez.
What if, after all, that grassy heap of brown earth hid riches—virgin ore from forgotten mines, or the minted coinage of old Spain? Was it not possible that the musketeers of de Estrada had themselves reared that pile above a treasure they could not bear away, molding it in the likeness of an Indian mound to fool seekers? Did old Lopez know that? It would not be strange if, knowing of treasure there, the old Mexican refrained from disturbing it. Ridden with grisly superstitious fears, he might well live out a life of barren toil rather than risk the wrath of lurking ghosts or devils—for the Mexicans say that hidden gold is always accursed, and surely there was supposed to be some especial doom resting on this mound. Well, Brill meditated, Latin-Indian devils had no terrors for the Anglo-Saxon, tormented by the demons of drouth and storm and crop failure.
