...before Christmas, Herman's trouser pocket began to bulge. Now and then, as he reached for the door lever, his pocket clinked. Going up from the ground floor, coming down from the sky, hearty businessmen full of good breakfast or luncheon, swooped under their overcoats and brought out folded bills, crumpled bills, gold coins...
...meterological conditions during the southern summer are rather unfavorable to astronomical observations. For this reason the Observatory has been experimenting in various South African regions for the past few years. After extensive observations, it appears, according to the scientists investigating the subject that during the cloudy season, the sky of the South African plateau is much clearer than that prevailing in Peru...
...point of observation from which to continue the work in photometry and spectroscopic survey begun in the Northern Hemisphere at the University. But Mount Harvard, as this spot was named, proved almost impossible for observations during the rainy season from October to May; when clouds cover the sky almost continuously. Other points in Peru and Chile were visited, and Arequipa was on the whole found to be the only practical choice. for although a station at Pampa Central, on the desort of Altacama in Chile, seemed to possess somewhat better climatic conditions, the living conditions were practically impossible...
Professor Pickering, Director of the Observatory at that time, finally authorized the recommendation that Arequipa be chosen as the permanent Southern station. For on this site there was not only almost as good a sky as in any part of South America, but excellent living facilities were obtainable for members of the Observatory's staff. In 1890, the main equipment for the station was sent to Arequipa. Throughout the years since then the Peruvian government has in every way possible assisted the efforts of the Observatory...
...this way an observer during the course of the year can see all the stars in the sky except those within 45 degrees of the south pole. These never rise above out horizon. Without working too near the horizon where observations are unfavorable, a person at Cambridge can observe about three-fourths of the sky, and for the most part under very favorable conditions. Stars within 45 degrees on the north pole never set, so that they may be observed as continuously as the Sun permits. The position of the Earth is a good one except for for southern stars...
