"Rather," was the reply. "Enough for 5000 miles; which means, allowing for deviations from a straight uniform course, about six halts to replenish petrol tanks. We carry no water ballast of any description. When the fuel supply runs low, there is a tendency for the airship to rise, owing to the reduced weight. To counteract this, a certain quantity of brodium is exhausted from the ballonets into cast-iron cylinders, where it is stored under pressure until required again. The leakage during this operation is less than one-half per cent. Now we’ll get on board." Past groups of busy workmen the three ex-officers made their way. Both Kenyon and Bramsdean noticed that the men worked as if they had an interest in what they were doing. Several they recognised as being in the same "Flight" in which they had served on the other side of the Channel. "Like old times," said Kenyon in a low voice. "Rather, old son," agreed his chum. They boarded the "Golden Hind," where workmen were putting finishing touches to the interior decorations of the cabins. The floor was composed of rigid aluminium plates, corrugated in order to provide a firm foothold, and temporarily covered with sacking to prevent undue wear upon the relatively soft metal. The door--one of the four--by which they entered was on the port side aft. It opened into a saloon 20 feet by 7 feet, which in turn communicated with a fore-and-aft alley-way extending almost the extreme length of the fuselage. "We’ll start right aft and work for’ard," said Fosterdyke. "If you can suggest any alterations in the internal fittings, let me know. It often happens that a new arrival spots something that the original designer has overlooked." "Must have taken some thinking out, sir," remarked Bramsdean. "M’yes," agreed Sir Reginald. "I’m afraid I spent some sleepless nights over the business. This is my cabin." The chums found themselves in a compartment measuring 15 feet in a fore-and-aft direction and 10 feet across the for’ard bulkhead, the width diminishing to the rounded end of the nacelle. It was plainly furnished. A canvas cot, a folding table, and two camp chairs comprising the principal contents. The large windows with celluloid panes afforded a wide outlook, while should the atmospheric conditions be favourable, the windows opened after the manner of those in a railway carriage. Retracing their steps, the chums inspected the motors immediately for’ard of the owner’s cabin. Each was in a compartment measuring 10 feet by 6 feet, leaving an uninterrupted alley-way nearly 3 feet in length between. "The fuel and oil tanks are underneath the alley-way," Fosterdyke pointed out. "I’m using pressure-feed in preference to gravity-feed. It keeps the centre of gravity lower. What do you think of the engines?" "Clinking little motors," replied Kenyon, enthusiastically, as he studied the spotlessly clean mechanism with professional interest.
