IN 1892 Prof. W. H. Pickering and others of the staff of the Arequipa Observatory were trying to establish meteorological stations in Peru, a region which up to the present has not been very well represented in meteorological observations. The meteorological station at Mollendo had been discontinued during 1890 and 1891, but observations were resumed there and at Arequipa during the early part of 1892, and in March a station was established at La Joya, a town midway between these two places.
