Then came May 4, a bitterly cold morning; but the stars shone brightly and there was every hope of the comet being visible from the tower heights. These hopes were confirmed, for on stepping out on to the parapet the writer saw the comet in all its splendor. The hazy-looking object seen on September 17, 1909, had developed into a full-grown comet with a head shining as a star of about the second magnitude, and surrounded by a nucleus. Extending outward like the beam of a searchlight gleamed the tail nearly fifteen degrees in length. Calling down to the janitor to make known the good news, the balcony was soon filled with eager members of the _Times_ staff, who were thus enabled to obtain a view of the comet. By means of a field-glass thoughtfully provided by Mr. Van Anda, it was possible to see a further extension of the train, making it in all thirty degrees in length. Spurts of light like tiny waves seemed to flow out from the nucleus to a distance of two or three degrees. At twenty minutes to four, the writer, on looking downward at the horizon, was startled by what appeared to be a streak of flame, but as it rose higher it proved to be the crescent moon, which with the comet and the planet Venus, completed a wonderful trio. The comet remained visible, resembling a bright star with a slender stream of silvery mist trailing a few degrees after. By four o’clock it had faded in the light of approaching dawn. A glance at the photograph of Halley’s comet obtained by Professor Barnard at the Yerkes Observatory on May 4 will give an idea of its splendor. For the next few mornings observations of the comet were disappointing, owing to heavy mists in the eastern skies. The comet was almost completely hidden from view, except on the morning of May 8, when occasional glimpses were obtained of it through rifts in the clouds. On May 10, the nucleus of the comet, from which extended a diminutive train eight degrees in length and fan-like in appearance, could be seen for a few brief moments, after which it remained hidden behind clouds until dawn, making further observations impossible.
