Aug. 7, 1869. Clear and cool. This is the day of the great eclipse of the sun. Just about four oclock p.m., as was calculated, the eclipse began. At 5 o'clock it was almost total, looked like twilight, only there was a strange, sombre appearance, quite unnatural. Nature shows signs of uneasiness when the sun hides his light in that way. How grand and solemn is such a sight, and how wonderful that man can calculate with certainty years beforehand such an event.
