Must Take Time to Submerge.

It requires at least five minutes for submarines of the latest type to submerge. A submarine cannot dive Quickly under the sea, because the water which must be let into her ballast tanks to make her heavy enough to alnk must be let in comparatively slowly. If it were let in with a rush the boat might not go down on an even keel, but would neel over and be in great danger of disaster. Then, too, if water were let in too quickly there would be danger of too much entering, and in that case the submarine would Pink like lead to the bottom of the sea.
