A minute or so before the totality, the complete circle of the moon was easily visible, with faint brushes of light streaming from it in all directions, which were soon to assume much larger dimensions, and, apparently, though not really, a greater brilliancy.
I cast now my eyes to the north-western horizon, and saw a brick-red tinge on the sky evidently caused by the rapidly approaching umbra. The long-expected moment had come; the last direct beam from the sun vanished, and a magnificent corona of rays, faint, of course, compared with the solar light, but bright in the prevailing gloom, shot out round the disc of the moon. These rays were prolonged in four directions at right angles to each other much more than elsewhere; having in these directions a length about equal to the sun's diameter, making the corona or aureola obviously cruciform in its shape.
Venus and Mercury appeared conspicuously on opposite sides of the moon, and Regulus could be seen, though with some difficulty. Several other first magnitude stars appeared in other parts of the sky, Arcturus, Vega, and Saturn being specially noticed by the observers at my side; and undoubtedly fainter ones could have been easily discerned, could one have been willing to divert his eyes from the beautiful sight placed before them, which seemed to surpass the expectations of every beholder. To all our party, I think, it conveyed little or no idea of horror or dread, but only of inexpressible beauty. The moon was at about one sixth of the distance to the zenith above the horizon, so that no straining of necks was necessary to look at it, as it hung over the darkened landscape. Certainly, as it so hung or floated, surrounded by the irrepressible splendor of the great source of light which lay behind it, and attended by its two bright planetary companions, one on each side, it was no unfit type of the glorious mystery which the church had just commemorated on the preceding day. The darkness was not so great as that of moonlight, but of course of a somewhat different character, the light not coming from one definite direction. I think it probable that no shadows were cast, but was too much occupied in other observations to be sure of this point. The birds around the building flew about wildly; and it was said that the fowls went to roost, and the cows started for home, and that the cocks crowed on the reappearance of the sun.
The eclipse had not lasted many seconds when I saw, without specially looking for it, a bright light red or orange drop on the lower edge of the moon, which of course was one of the famous protuberances. It was easily seen with the naked eye, though probably many who had not heard of these appearances did not notice it. Before the end of the obscuration, another appeared on the right where the sun was about to emerge. A third was also visible to the telescope above. Possibly they may have had some connection with the long rays of the corona.
Before we had fairly begun to satisfy our curiosity, a well-marked boundary between the general darkness and a bright portion of sky to the north-west gave warning of the end of the eclipse, and immediately afterward the sun flashed out on the right.
The separation of the discs of the sun and moon during the following hour was probably carefully observed by few except the astronomers and photographers; the moment of interest had passed, and few cared to do more than exchange congratulations on the success of the display. I forgot to notice whether the corona and prominences were visible after the totality; the latter were still seen, according to accounts received from elsewhere, and I met with one gentleman some days afterward who had seen the great protuberance on the lower edge of the sun at Shelbyville, Indiana, a point some fifteen miles from the outside line of totality; he had, of course, no previous suspicion of its existence.
The eclipse was naturally the principal topic of conversation during the evening, and every one was anxious to report his own observations and learn those of others. I found that eleven spectral lines had been seen by Professor Winlock in the great prominence, some of them characteristic of the metal magnesium. He saw only three before and after totality; thus confirming the idea previously entertained, that solar eclipses, though not the only occasions on which these interesting objects may be seen, are, with our present apparatus, far the best. The photographers had taken some eighty pictures, several during the totality, and the times of beginning and ending had been accurately observed both at Shelbyville and, as we afterward learned, also at the stations on the border line, Falmouth and Oakland; which border observations give the position and breadth of the path of the shadow within some eight or ten rods; the southern edge can even be determined with much greater accuracy, owing to a fortunate selection of the station, which proved to be extremely near it. The precise amounts by which these results differ from the previous computations have yet to be determined; but it is probable that the corrections to the tables now used will be very small.
An ingenious method of observing the time of the external contacts, or beginning and end of the whole eclipse, was, as I heard, devised by a gentleman at another station. These phenomena, especially the first, are very difficult to observe accurately, owing to the invisibility of the moon when off of the sun's disc, and the waviness of the sun's limb, making it doubtful that an indentation has been made in it till it has become quite deep, which is, of course, some time after the actual meeting of the two bodies. He observed it with the spectroscope by noting the time of disappearance of one of the lines only visible on the extreme edge of the sun's disc.
Every one not engrossed in some special work had, of course, seen the planets Venus and Mercury; and many had seen others of the first magnitude. The darkness was not so great as was hoped for by those who were searching for intra-Mercurial planets; no candle was necessary for examining the charts which had been prepared. One observer at Shelbyville reported having seen a star of the third magnitude with the naked eye, and as he had no previous knowledge of the existence of such a star in the place in which he was looking, the fact seems indubitable. Dr. B. A. Gould, of Cambridge, who observed at Burlington, Iowa, has since informed me that he saw a star of the fifth magnitude, with a telescope of five inches aperture, near the sun; the star is a well-known one, and the observation shows that, had any planets of that brilliancy (about one fiftieth of that of Mercury) been within three degrees of the sun, within which limits he was restricted in his search by the shortness of time, he would not have failed to detect them.
"Baily's beads" do not appear to have been considered as extraordinary by any of the observers. The limb of the sun just before the totality was of course more or less broken up by the irregularities of that of the moon; but the fragments had no remarkable appearance; and this phenomenon, which has been the subject of so much discussion, seems probably due to irradiation and the difficulty of determining the precise shape of small and brilliant objects.
