Irrigation district act passed. 
PRESENT STATUS OF IRRIGATION DISTRICTS. 
A number of irrigation districts had been formed prior to 1910, 
there being a period of marked development in California from 1887 
to 1893 and to a lesser extent at a later date in a few other States. 
About 1910 interest began to revive in California, in which no district 
had been formed since 1895, and also in Washington, and developed 
shortly afterwards in Arizona and Texas. Progress was slow for a 
few years, however, due to the unwillingness of eastern and middle 
western investors to consider irrigation bonds and to the necessity 
of disposing of bonds almost entirely to local people familiar with 
the merits of the enterprises issuing them. In the meantime such 
additional safeguards had been thrown about the formation and 
bonding of districts in California that gradually a fairly dependable 
market began to be built up there, and by 1917 and 1918 irrigation 
districts in a number of States began to find it possible to market 
their bonds. Bonds of districts which already have established 
values behind them are now disposed of much more readily than 
those issued to provide for future development, the effect of which 
is that present-day development by irrigation districts is generally 
conservative.
