breeze. She will be put through every
nossibfe maneuver. For hours she will go
at full speed, the engines working at their
highest tension. Then the machinery will
be:stopped and every bearing critically ex-
amined. Again she will be used with first
one propeller and then the other. She
will be swung round in a circle and backed
furf0usly astern. Outside the Farallones
she will cut as many antics in the water
as a boy would on ice; then, when after
week of rigorous trial the builders are con-
yfnced that she is ready, the Navy Depart
ment. will be asked to put her through ner
PAGES.
Although Uncle Sam requires that the
different tests be severe yet his rules are
faYOra BILE to contractors. There is only
one official trial trip of every man-of-war.
On this trip the Government paws all the
expenses, but the contractors are permitted
TO say which trip shall be the otlcial one.
For instanre, suppose the Olympia to nave
returned from a successful cruise around
the islands, and everything being in SEEM
ing readiness. the Union Iron Works had
announced a day for the official test. If
on this day some slight accident should
happen to The machinery then the naval
board could be asked not to consider that
trip as official, but wait until repairs should
be made, when another trial could be had.
These tIips are all made at the contractors
expense. the Government only paying Tor
the one which IS finally determined upon as
official.
If everything runs smoothly on the
Olympia this week the final test Will prob
ably be made within ten days. The offi-
GERS. at Mare Island have received their
Instructions and can join the new cruiser
within few hours notice. In addition to

=. For previous trial trips the course in
p Santa: Barbara Channel has been laid at
forty miles, and signal points at different
: PLACES on shore have enabled the officers
on board to accurately judge the speed.
=" The official trip must cover four hours,
the course must be doubled, and the time
taken In turning is included. As the
Olympia will probably make over twenty
one knots, this course is not long enough.
so last week the Patterson was ordered to
IengtheD 1t to f0rty-three miles, and she
was at the work for several DAYS. Thus
the round-trip course for the Olympia will
be eighty-siX miles, and TO cover it all she
willhaye to make speed of 2lh knots an
hour. This her builders think she can do.
. They don't boast much about her, but
there are some men in the Union Iron
Works yard, men who have watched the
