A small part of the land surveyed, as indicated by ,the tables, 
was yet uncleared and uncultivated and is classed as sagebrush. 
The survey having been made during two winter seasons, no determi- 
nation as to the extent of the fallow land could be made. The pro- 
portion of this land, however, was practically negligible and could 
not possibly have exceeded 1 or 2 per cent. The 20 sections included 
in the investigation in the vicinity of Meridian averaged 10.65 farms 
per section. Space will not permit of a detailed description of each 
section included in the investigation or of the results obtained. 
The results show, in addition to other factors, that the total land 
unirrigated from all possible causes, even including the unirrigated 
strips along the fence rows, amounted to only 8.1 per cent of the 
total area surveyed. The land included was not the best nor the 
most intensively cultivated of Idaho irrigated land, but it undoubt- 
edly did represent a little better than average conditions, for neither 
the main canal nor the rough, rolling land that is common along 
the main stream was included. The data secured therefore seem 
to demonstrate that well-developed projects will never contain more 
than 10 to 124 per cent of land which is waste or unirrigated in any 
one year from all different causes, provided the percentage is based 
upon no greater gross area than that from which annual maintenance 
can be reasonably expected.
