De la Landelle鈥檚 work, already mentioned, was carried on a few years later by another Frenchman, Castel, who constructed a machine with eight propellers arranged in two fours and driven by a compressed air motor or engine. The model with which Castel experimented had a total weight of only 49 lbs.; it rose in the air and smashed itself by driving against a wall, and the inventor does not seem to have proceeded further. Contemporary with Castel was Professor Forlanini, whose design was for a machine very similar to de la Landelle鈥檚, with two superposed screws. This88 machine ranks as the second on the helicopter principle to achieve flight; it remained in the air for no less than the third of a minute in one of its trials. � In the matter of rigid design it was not until 1913 that the British Admiralty got over the fact that the 鈥楳ayfly鈥?would not, and decided on a further attempt at the construction of a rigid dirigible. The contract for this was signed in March of 1914; work was suspended in the following February and begun again in July, 1915, but it was not until January of 1917 that the ship was finished, while her trials were not completed until March of 1917, when she was taken over by the Admiralty. The details of the construction and trial of this vessel, known as 鈥楴o. 9,鈥?go to show that she did not quite fill the contract requirements in respect of disposable lift until a number of alterations had been made. The contract specified that a speed of at least366 45 miles per hour was to be attained at full engine power, while a minimum disposable lift of 5 tons was to be available for movable weights, and the airship was to be capable of rising to a height of 2,000 feet. Driven by four Wolseley Maybach engines of 180 horse-power each, the lift of the vessel was not sufficient, so it was decided to remove the two engines in the after car and replace them by a single engine of 250 horse-power. With this the vessel reached the contract speed of 45 miles per hour with a cruising radius of 18 hours, equivalent to 800 miles when the engines were running at full speed. The vessel served admirably as a training airship, for, by the time she was completed, the No. 23 class of rigid airship had come to being, and thus No. 9 was already out of date. 9 Thus was Satan's war with Adam defeated.

Will those men at the South, to whom God has given the power to perceive and the heart to feel the unutterable wrong and injustice of slavery, always remain silent and inactive? What nobler ambition to a Southern man than to deliver his country from this disgrace? From the South must the deliverer arise. How long shall he delay? There is a crown brighter than any earthly ambition has ever worn,鈥攖here is a laurel which will not fade: it is prepared and waiting for that hero who shall rise up for liberty at the South, and free that noble and beautiful country from the burden and disgrace of slavery.
