"At first it had been an almost telescopic speck; it had brightened to the dimensions of the greatest star in the heavens; it had still grown, hour by hour, in its incredibly swift, its noiseless and inevitable rush upon our earth, until it had equaled and surpassed the moon. Now it was the most splendid thing this sky of earth has ever held. I have never seen a photograph that gave a proper idea of it. Never at any time did it assume the conventional tailed outline, comets are supposed to have."
