Haven't you seen pieces of pumice stone

err" was asked
Mine sinks" was the witness reply
Most pu1nice stones sink in water"
He thought he might order rock for sink
| ing purposes by weight per cubic foot for
some reasons, and by specific gravity for
others.
If asked for the specific gravity of hol-
| low steel sphere he would consider the re-
quest peculiar one and ask for further
| information. The specific gravity of the
sphere intact coald be given if called for.
The specific gravity of rocks, Mr. Fin
ney said, ranges from about "a to g. The
lowest specific gravity of any rock known
as just little below 2. If he was called
on for large amount of work of a spe-
citic gravity below "a he did not know
where 1t could be secured nearer than
| North Carolina.
On the redirect examination by Mr.
| Blair, Mr.. Flnney said specific gravity and
weight per cubic foot have no connection
| whatever.
Mr. George Y. Wisner, civil engineer,
member of the Ameican Society of
| Civil Engineers, member of the Deep
Waterways Commission appointed by
the President an engineer of twenty
years experience in hydraulic engin-
| eering and jetty work under ff-
teen different members of the en-
gineer corps, especially in the Mississippi
and Brazos rivers was the second wit
ness for the defense. He is graduate of
the University of Michigan and has had
thirty-three years experience as an enA
gineer
In his opinion, If Capt. Carriers project
for improving Cumberland Sound made in
1890 had been adopted and carried out.
there would have been a saving of more
than 100000 to the government. That
project was disapproved and he consid-
cred this made the Improvement less prac-
tcable and more expensive.
The prosecution contended that Capt.
Carter violated the specifications and in
structions of the board of engineers in the
Cumberland sound improvements. Mr..
Wisners testimony was to show that
Capt. Carriers Interpretation of the board $
action was the correct one.
In his experience. Mr.. Wisner said, adj
vertisements for river and harbor work
had been published from ten days to more
than month. depending upon the neces-
stiles of the case. The law. he said, mere
ly required a reasonable time. So far as
he had seen, the general custom was to
send only one copy of the specifica tions TO
a contractor, except in special instances.
The bids were usually put in two or three
minutes before the time for opening them
and the contractors then were watching
one another closely and figuring more on
the competition than on what they could
do the work for.
A plant costing not less than $50, 900
would be necessary to do the work under
the Cuberland Sound contract Insurance,
repairs and deterioration of such a plant
had to be taken into consideration to a
large extent. Half of such plant might
be wiped out by a single storm
Mr.. Cooper's method of determining spe.
cific gravity, he said was incorrect. 1t
would give the specific gravity of the rock
and water combined The weight of a Gu
bic foot of the stone had no relation to its
specific gravity.
The Florida rock, Mr.. Wisner considered,
has peculiar properties which make it ex-
cellent for jetty building under certain cir
cumstances. The marine growth adheres
to it more readily than to granite, and It
forms practically a monoltth.
"Wen trimmed" Mr.. Wisnec said, did
not mean that all of the leaves and twigs
should be removed from the fascines. I'm
der the contracts of 1896 he would not ac-
; cept military fascines from the contractors,
because they would not answer for the
work. Currents running through mat
tresses of military fascines win scour out
the sand and cause a subsistence. The null
, tiple mat of six or eight courses Mr.. Wis
ner considered within the meaning of the
specifications.
The object in building a ietty in place
like Cumberland sound is 10 carry the
bar out 10 sea, and in order TO do this,
the witness said, it must be constructed
rapidly as TO keep up the securing
He said he thought The plan pursued by
Capt Carter would have resulted most
advantageously for the government. An
| eight-course mattress might be built in ac-
cordance with the specifications, and be
only nine feet in hight, MIR. Wisner said.
Mr.. Cooper had testified that il would
have to be twelve feet high.
If the three designs of mattresses i'm the
specifications had been open to a different
bid on each, he would have bid the same
price for all of them.
| AS an engineering work, the work In the
Savannah river, he said. was an undoubt-
ed success. The silt now being deposited
in the river. he said, was coming from a
cavng bank. and could be easily stopped
If the military fascine mattress had been
used in the Savannah river instead of the
multiple mattress, the work would have
cost the government at least 81 600 600
more even if it had been success.
Witness S. M. Hale went with him and
others to Hilton Head Island beach on
Sunday and pointed out all the places
where he had seen brush said to have
been washed from the Tybee breakwater
This brush was measured by MIR. Wisner
and ne said there was less than 20 cubic
| yards all told. That was all they could
find after a thorough search.
what would YOU say as TO Mr.. Hale's
4 estimate Of 5000 square yards Of brush
