The State Agricultural Experiment Station:—In 
its study of the water supply in relation to agri¬ 
culture, of soils in their geological relations, and in

and other publications of the National Geological Survey; 
the reports of the Canadian, and a few other foreign Geo¬

however, been used for this purpose. Three cases have 
been built, designed to serve the'double purpose of storage 
and exhibition, the lower part of the case being adapted 
to the purpose of storing material. In making the collec-
