Still Baldwin shook his head, remarking that the Seagull was full 900 tons.
“Well, then,” resumed the young engineer, “here is still another method. We might send down your men to make all the openings,—ports, windows, etcetera—water-tight, fix a shield over the hole she knocked in her bottom on the cliffs, and then, by means of several water-pumps reaching from above the surface to the hold, clear her of water. When sufficiently floated by such means a steam-tug could haul her into port. The iron steamship London was, not long ago, raised and saved at Dundee in that way. She rose four feet after the pumps had been worked only two hours, and while she was being towed into dock the pumps were still kept going. It was a great success—and so may it be in this case. Then, you know, we might construct a pontoon by making a raft to float on a multitude of empty barrels, pass chains under the Seagull and fix them to this pontoon at low water, so that when the tide rose she would rise perforce along with the pontoon and tide, and could be moved inshore till she grounded; then, waiting for low tide, we could taughten the chains again, and repeat the process till we got her ashore. Or, better still, we could hire Siebe and Gorman’s patent pontoon, which, if I mistake not, is much the same thing that I now suggest carried out to perfection.”
“I’m not sure that the pontoon you speak of has been launched yet. I’m afraid it’s only in model,” said Baldwin.
“More’s the pity,” rejoined Edgar, “but I can go to London and ascertain. In any case, I shall have to go to London to make inquiries, and secure the necessary apparatus.”
“Are you sure,” said Baldwin, with a look of great solemnity, “that your going to London has nothing whatever to do with apparatus of that sort?”
He placed a blunt forefinger, as he spoke on the obliterated sketch of the female head.
“Oh you suspicious old fellow!” replied Edgar; “come, you are presuming now.—We will change the subject, and go on deck.”
“Human natur’s the same everywhere,” observed Baldwin, with a quiet laugh as he rose. “Same with me exactly when I was after Susan. For one glance of her black eye I’d have gone straight off to China or Timbuctoo at half-an-hour’s notice. Well, well!—Now, Mister Eddy, don’t you think it would be as well for you to go down and have a look at the wreck? You’ll then be better able to judge as to what’s best to be done, an’ I’ve got a noo dress by the firm of Denayrouze, with a speakin’-apparatus, which’ll fit you. I got it for myself, and we’re much about a size—barrin’ the waist, in which I have the advantage of you as to girth. Their noo pump and lamp, too, will interest you. See, here is the pump.”
As he spoke, the diver pointed to a pump which commended itself at first sight by its extreme simplicity. Whether or not it was better than the more complex, but well-tried, pumps of other makers, our hero was well aware could only be proved by time and experience. Meanwhile he was favourably impressed with it.
The peculiarities of the pump referred to were, first, and most obvious, that it had no outer wooden case or box, and the parts were exceedingly few and simple. It was on the lever principle, the cylinders, instead of the pistons, being movable. The pistons were fixed to a bed-plate and pointed upwards, so that the pump was, as it were, turned upside down, a position which, among other advantages, allowed of the plungers being covered with water, through which the air was forced and partially cooled. Another and important peculiarity was an air-reservoir which received air from the pump direct, and then passed it on to the diver, so that even if the pumps should stop working there would still be a supply of air flowing down to the diver for several minutes. The lamp referred to was also a novelty, inasmuch as it was supplied with air by a separate tube from the reservoir in the same way as if it were a separate human diver. The Henkie and Davis lamp burns, on the other hand, entirely without air, by means of certain acids. That of Siebe and Gorman is an electric-lamp. Both are said to be effective and economical.
