As for the cross-bows they made, they were grand with screws." There were five boys and six girls in the Gordon family. Charlie was the fourth son, and two of his elder brothers were soldiers while he was still quite a little lad.

Then the pumps were worked some more, and other blocks put under, till the wharf was restored to the required level. Great screws such as are used in raising buildings were also employed under wharves sometimes. There were rocks under some wharves, and water was under others.

"A hold-up?" "Oh, thumb screws, you know the same old quick-step to the altar. I hadn't done a thing, I tell you, but it looked as if she thought that our being there was something she could stage a scene on and so I thought you don't know what things have been tried on me before," he broke off to protest at Barry's expression.

By this time she was about seven miles away, and the Lurline, her twin screws beating the water at their utmost speed, and every plate in her trembling under the vibration of her engines, rushed through the water faster than she had ever done since the day she was launched.
