across ella at Maricopa was rebuilt
half dozen times during that month.
1t is apparent therefore that materials
for construction work were not hauled
into camp very rapidly during part of
the past winter.
II might be said of the unwelcome

ing the banks. The grading work for
this canal was done by Sherer & Co.
OF Los Angeles, and the tunnel work
by John Tuttle OF San Francisco. Wa
ter will be diverted from the river to
the power canal about a quarter of
mile below the confluence of Pinal
creek and Salt river. The canal is 10
miles long and its construction has
involved the excavation of about 600,-
600 cubic yards of material and the
driving of nearly 5000 feet of tunnel.
Until power can be obtained from
the power canal, a temporary steam
plant has been built for the purpose
OF furnishing power to the machine
and wood shops and for running the
cement mill. 1t has also run the hoist
for the material. which has to be ele-
waited 800 feet to the cement mill,
and has furnished light and power for
drilling operations in the tunnels at
the dam.
The cement mill, which has been
ready to run since the middle of Feb
ruary, is now in operation. The fuel

through the fact that only one tank
of oil reached the mill during March.

About 400 tons of machinery and so
tons of structural iron have gone into
the construction of the cement plant.

two chemists, who will devote all
their time to standardizing the cement
materials and testing the products OF
the mill. 1t is expected that about
100000 barrels of cement will be re-
quired in the construction of the
Roosevelt dam, the power canal, and
the various Tonto improvements. The
cement used in the preliminary work
cost $5.35 a barrel delivered at the

later received for furnishing cement
