 this department of the station during- 1899, as in previous years (E.

" The measurements to determine the gains or losses from seepage have been con- 

 tinued this year on streams previously measured. These include the Cache la 

 Poudre, from the canyon to its mouth, a distance of 50 miles; the Big Thompson, 

 about the same distance; the Little Thompson, a tnhulary of tlic Big Thompson;
