Their existence together would soon have become impossible, but an unexpected event cut short these eternal discussions.

During the night between the 14th and 15th of December the two irreconcilable friends were occupied in observing the lunar disc. J.T. Maston was, as usual, saying strong things to the learned Belfast, who was getting angry too. The Secretary of the Gun Club declared for the thousandth time that he had just perceived the projectile, adding even that Michel Ardan's face had appeared at one of the port-lights. He was emphasising his arguments by a series of gestures which his redoubtable hook rendered dangerous.

At that moment Belfast's servant appeared upon the platform—it was 10 p.m.—and gave him a telegram. It was the message from the Commander of the Susquehanna.

Belfast tore the envelope, read the inclosure, and uttered a cry.

"What is it?" said J.T. Maston.

"It's the bullet!"

"What of that?"

"It has fallen upon the earth!"

Another cry; this time a howl answered him.

He turned towards J.T. Maston. The unfortunate fellow, leaning imprudently over the metal tube, had disappeared down the immense telescope—a fall of 280 feet! Belfast, distracted, rushed towards the orifice of the reflector.
