As before said, the last piece of machinery and the first rain arrived simultaneously at Santa Gertrudis. The break in the summer heat came with a south wind which herded mountainous vapors in from the warm Pacific. All night the rain fell in sheets that set the thirsty arroyos running bank-high and raised the river ten feet. Then, after the pleasant tropical fashion, the downpour ceased, and day broke with a blaze of sunlight over the Barranca.

“Sinbad’s valley of diamonds!”

It was Billy’s metaphor when he came out with Seyd from breakfast, and, trite as the comparison might be, nothing else could better describe the millions of wet jewels that flashed in the dark mantle of pine above and embroidered the green cloak of the jungle beneath. Yesterday had seen the last touches put on the aerial cable which would be soon dropping buckets of ore into the red jaws of the furnace two thousand feet below. From the edge of the plateau it ran, a streak of silver fringed with glittering rain drops, down and out to the smelter; and when, in the pride of his heart, Billy loosed the brakes the first vibration threw off a cloud of prismatic spray.

“Balanced to a hair! You see, the weight of one full bucket is sufficient to start the chain.”

“Fine!” Seyd echoed. “Runs like a clock. Another week and we’ll be running steady.”

Standing there, watching the buckets sail up and down like great iron birds, they gave themselves up to the joy of accomplishment; as once before, permitted fancy to run amuck through the golden future. And after their hard labors and prolonged anxieties a little self-congratulation was quite in order. If, one way or another, they succeeded in meeting their first note they really could be counted in splendid shape, for their shipments of copper matte would be on the market before the second fell due.

Billy nodded assent when Seyd spoke. “Francesca said they would be home to-day. I think I’ll run down there and tackle Don Luis.”

Between them were no secrets, and when Seyd rode away an hour later with Caliban at his heels Billy called after him: “And say, old man, have it out with the girl. If she has half the brains I have always allowed her she’ll easily see the accidental way in which it all came about.”

Though the advice merely restated his own intention, Seyd found it inspiring. Riding down the Barranca staircases, he whistled and sang. While following the trail through the long succession of ranchos, jungle, hamlets, he lived over again that first ride with Francesca. Very plainly he now perceived that it dated his love, that in the pauses of his stealthy study she had ensnared him with her rich personality.
