They handed him their cards. Carlos’ was edged with black. Soon the servant returned, and said that Colonel Conrad would see them.

They were ushered through a wide hall, on the left side of which was the room where Colonel Conrad awaited them.

The servant bowed them in.

The room was not a large one, but it was fitted up with elegance and taste. On one side was a row of shelves, on which were ranged books of all sizes and colors.

It was the colonel’s library, and a choice one it was, too, valuable principally for the age and rarity of some of the volumes.

There was a fire-place, a writing-table, a closed desk, heavy, rich, and antique in pattern, a huge clock, reaching from the floor to the ceiling, a smaller case of book-shelves near it, a couch, and a few chairs.

All this was taken in at a glance, as was also the figure of the proprietor of the mansion, seated in an easy-chair, with an open book lying on the table beside him.

Never were two persons more surprised than were the cousins at the appearance of Colonel Conrad. They hadexpected to see in their uncle a large, frowzy, ferocious-looking monster in human form, with a face expressive of malice, and that peculiar expression that always belongs to lips given to invective and denunciation.

Instead, there sat before them a man not above the medium size, with hair thickly tinged with gray, and a careworn, studious, thoughtful face. His eyes were blue, and, in contrast with his appearance otherwise, were bright as those of a youth of twenty. His brow was wrinkled irregularly, suggesting inward conflict and mental anxiety.

He sat and looked at his nephews steadily without speaking. Carlos gazed earnestly and apprehensively into his face, while Leonard stood in an easy attitude, apparently not in the least discomfited.
