and west ends of the upper plateau. One I left open in the usual 

 way, the other one I surmounted with a framework representing a 

 bunch of reeds. The arrangement consisted of two rings of 5 inches 

 diameter, which were connected by four rods of stout wire, the 

 whole frame being 1 foot high. Pieces of wire netting were fixed 

 inside the rings, and reeds were drawn through the meshes and 

 fastened with thin wire. The frame was then inserted into the 

 other rain gauge, fitting into its opening by means of a narrow 

 socket. Four wires attached at opposite sides and fastened to 

 stones near by protected the frame against the fury of the wind. I 

 had consequently one ordinary gauge and one with an imitation 

 bunch of reeds 1 foot high. 



The first reading of my gauges was made eleven days afterwards, 

 on the day when I had the pleasure of revealing the charms of our 

 mountain to a distinguished party of explorers, viz., to Professor 

 von Drygalski and several members of the German Antarctic Expe- 

 dition. The gauge with the reeds had overflown, while the other 

 one was also nearly full, there having been a heavy rain a few days 

 before. Although the difference was not large, it was evident that 

 the reeds had caught some water. With the aid of some members 

 of the Mountain Club the readings were made at intervals of seven 

 or ten or fourteen days. We found, however, very soon that the 

 bottles which I used were too small ; at least that one with the reeds 

 was full every time we came there. I substituted a bottle of double 

 the size, but also that one was generally quite full, compelling 

 me to take up another one which was capable of holding still 

 more. By that time, however, the summer of 1902 was nearly 

 over, and although we continued the readings for some time during 

 the winter, I do not intend to include this part of my observations 

 in this paper, because I found that the reeds caught an enormous 

 amount of rain, which is so largely in excess of that shown by the 

 open gauge, that it may well form the subject of another investi- 

 gation. 



At the beginning of last summer I set to work again, but, owing 

 to some delays, the gauges were put in order only on December 21, 



1902. The first reading of the season was made on January 1, 



1903, when it was found that the open gauge contained nothing, 

 while the other one showed 15-22 inches of moisture, and that for a 

 period of ten days. The next reading took place on the 11th of 

 January. The open gauge was again dry, the other one showing 

 14'64 inches. In twenty-one days the reeds had condensed mois- 

 ture corresponding to 29 '86 inches of rain, while the open gauge 

 showed nothing.
