During the construction of the works
already completed, two thriving towns
have been built, at Richfield and Good

first named town is only seven months
old, and already has population APP

fine modern hotel costing $4,000 to con-.
strnct handsome stone and brick store
buildings. and modern cottage resi-
dences, the growth that follows upon
irrigation enterprises will be better un-
derstood.
ANOTHER SEGREGATION
During the latter part of the summer
of 1908. the Idaho Irrigation company
determined that its plans provided
more water than was sufficient for the
irrigation of all the Carey act, state
and private owned land under their
projected canals, and a petition was
filed with the state land board request
ing the segregation of about $1,000
acres of choice land lying along the
main line of the Oregon Short Line
railroad. Immediately east Of the
town OF Shoshpne. After investigation
the segregation was made, and the COM
pany began the work of preparing to
furnish water to these lands by the first
of April. 1910 The contract with the
state was made and signed and the
state land board has decided to open
these lands to entry on June s, 1908.
The opening Is to be held at Shoshone
and precedence in filing is to be de-
ternined by lot, the experience Of the
state with all previous Carey act OPEN
ings having made clear that this is the
best method.
GREAT STORAGE RESERVOIR

The great storage reservoir, now I'M
der construction by the company, and
which it is expected will take two years
to complete, is the first of its kind of
any magnitude in Idaho. The dam
that will form the reservoir, is of what
Is called a rock-tlled type. The dimen-
sions are: On the bottom 49, feet wide;
at the top 40 feet wide: height 135 feet;
extreme length 200 feet The dam
will nave Il rock toe, with Il
vertical height of 40 feet
and a rock heel of the same dimen-
