Lennard's first feelings after the receipt of Mr Parmenter's cablegram, and the casting of the vast mass of metal which was to form the body of the great cannon, were those of doubt and hesitation, mingled, possibly, with that sense of semi-irresponsibility which will for a time overcome the most highly-disciplined mind when some great task has been completed for the time being.
For a full month nothing could be done to the cannon, since it would take quite that time for the metal to cool. Everything else had been done or made ready. The huge projectile which was to wing its way into Space to do battle for the life of humanity was completed. The boring and rifling tools were finished, and all the materials for the driving and the bursting charges were ready at hand for putting into their final form when the work of loading up began. There was literally nothing more to be done. All that human labour, skill and foresight could achieve for the present had been accomplished.
