"That so?" replied Blake in a tone that brought a glint of excitement into the worn eyes of the older engineer.

But before he could speak, a silk-robed figure stepped out onto the verandah of the Resident Engineer's office, and called delightedly, "Ah, Lord Avondale!—welcome to Michamac! You escaped my hospitality in town, but you can't here!"

"Thanks. Very good of you, I'm sure," replied Lord James dryly.
