Book excerpt: Excerpt from Report on the Total Eclipse of the Sun: Observed at Mina Bronces, Chile, on April 16, 1893 The peculiarly favorable location of the track of the moon's shadow during the total eclipse of April 16, 1893, rendered it extremely desirable to occupy various points along this line as observing stations. The interval of time between the extreme positions which could be advantageously occupied being of several hours' duration, it might be possible to detect with certainty changes in the form of the corona during this interval. It was decided that if the Lick Observatory could secure the necessary funds to send out an expedition, some point in the interior of Chile should be selected for observing the eclipse, as the atmospheric conditions throughout the Desert of Atacama were known to be excellent. Mrs. Phebe Hearst, a friend of the Observatory, had provided in 1892 a fund which was to be used in aid of scientific undertakings at the Observatory. On the recommendation of the Director of the Observatory, and with her cordial sanction, the sum of $1,000 from the Hearst Fund was set aside for the expenses of the expedition in the field. The Regents of the University authorized the use of the necessary instruments. Preparations for the eclipse were commenced in the fall of 1892. I was particularly desirous of photographing certain phenomena on a very much larger scale than had ever before been done, for it seemed that only in this way could certain doubtful points be decided, and marked advantages be gained over the usual results. The finer details of the corona are necessarily lost in photographs taken on a small scale. Special attention was therefore first given to the designing of an instrument which should be capable of furnishing satisfactory results on a very large scale when used under the peculiar conditions presumably prevailing in the interior of Chile.
