A new set of drain gages, provided with an artificial water table, were set up at 

 Geneva in 1888, but thus far the results gained with them have not been discussed at 

 length in the Annual Reports. As to whether or not the Geneva gages are 

 still in service is unknown, although the author cannot but think that some agricultural 

 station, at any rate, should carry out to final conclusions such a set of experiments as 

 was begun at Geneva. 



RISLER'S paper on evaporation from the soil. 



Probably the most satisfactory data as to evaporation from soil are contained in a 

 paper, Sur V Evaporation du Sol, by E. Risler, published in the Bibliotheque Universelle 

 et Revue Suisse, Archives des Sciences Physiques ct Naturelles, for September, 1869. 

 In this paper Risler gives the detail of experiments carried out by him on his estate at 

 Caleves, near Nyon, Switzerland. The following matter is translated from the paper: 

 1 "Meteorologists have made many attempts to procure the proportion of the 

 rainfall which is returned to the atmosphere by evaporation either directly by- 

 evaporation from the ground, or by passing through vegetation. To determine these 

 facts, different methods have been used.
