However, it was decided to try her.

Having managed all the details of her construction, Boyton ordered her swung under a big pair of shears and from their support hung the boat on chains, so that in case she would not run to the surface by her own power, she could be hoisted by the machinery above.

She was then lowered to the water.

Paul and two of his crew entered, but before descending to the bottom, gave orders to those manning the shears, to hoist at the expiration of twenty minutes.

After fastening the man-hole, the valves were closed.
