SEEPAGE EROM CANALS IN THE SAN LUIS N^ALLEV. 
Measurements were made to determine the loss by 
seepage and absorption on a number of canals and on later- 
als, approaching canals in size, in the San Luis valley, and 
the measurements are given in the following tables. These 
include measurements of the losses on the Empire canal, on 
the Blackmore or Fisk Ditch, on the Prairie Ditch, on a
