Blood did not heed them.

And then at the end of the line there was a movement.

Gardner was speaking in a loud voice, making an announcement to the general public of buyers that had waited until Colonel Bishop had taken his choice of that human merchandise.

As he finished, Blood, looking in his direction, noticed that the girl was speaking to Bishop, and pointing up the line with a silver-hilted riding-whip she carried.

Bishop shaded his eyes with his hand to look in the direction in which she was pointing.
Then slowly, with his ponderous, rolling gait, he approached again accompanied by Gardner, and followed by the lady and the Governor.
On they came until the Colonel was abreast of Blood.
