Traces Guns Evolution.
Col. Goddard displayed to the jurors
a set of barrels which demonstrated
the evolution of the barrel from piece
of ordinary steel to the finished gun
barrel. He exhibited one length of
metal which had not had a barrel
drilled in It,
LAS the bullet leaves the barrel from
different angles the location of marks
left by the grooves often is different.
but the marks are the same, in so far as
each weapon is concerned" the witness
declared.
Goddard said the barrel is the first
stage in the manufacture of pistol
He said as the barrels are drilled by
machinery the metal is shaved away in
very small quantities. He said the teeth
of the machine used in this work
change microscopically as they are
worn away, causing each barrel to have
distinctive marks.
Several questions were asked of the
witness by the jurors as he displayed
the various exhibits. Most of his eX-
plantations were inaudible as far away
as the press tables because attorneys
for both sides were crowded about him.

Sheriff Testifies.
A veteran Virginia sheriff testified
yesterday afternoon that Campbell
talked of the killing of Mary Baker
until the stories resulted in charge
of murder against the man. The wit
ness was Sheriff Howard E. Fields OF
Arlington County, a peace officer since
1897. He was followed on the stand
by william C. Cloth, Commonwealth
attorney for Arlington County.
The court room was very quiet as
Cloth quoted Campbell as saying after
a grueling examination in July:
You have enough on me to arrest
me, indict me, try me, convict me and
execute me. Why should 1 tell you any
more?"
Both witnesses, however, said Camp
bell went no further than admitting
that long series of stories he told them
was untrue and that he denied that he
killed the girl or knew who did.
The sheliff's story, told in a matter
of-fact voice, was recital of the bizarre
tales told by Campbell about the Baker
case until Fields said lit looked suspi-
| ciouS."
The young Government worker had
been dead only short time, Fields said,
when Campbell came to him and said
pair of pigskin gloves found with other
clothing belonging to Miss Baker were
his. The clothing lay only a short dis
lance from where the body was dis
covered in a culvert on the morning of
April IL. Campbell said he suspected
Herman Barrere, itinerant painter, of
stealing the gloves.
He kept coming back to me-" Fields
said, land telling me that he thought
Barrere was the guilty man." Barrere
was arrested in Montreal He proved to
the satisfaction of authorities that he
had nothing to do with the crime and
attention turned to Campbell
The latter,s actions, even before Bar
rare's arrest, had placed him high on
the list of suspects Fields said, and this
conceded with Cloths testimony. The
sheriff said he thought it very strange
when Campbell came into his Office one
day carrying package. In the bundle
was gun, Campbell's gun, and the Of
ficer testified the real estate dealer said
he believed the weapon had killed Miss
Baker.
Wanted Gun Examined.
"He said he wanted it examined by
experts, the sheriff said, land went on
that he believed Herman Barrere stole
the gun. shot Miss Baker with 1t and
sent it back by a man with a wart on
his nose"
Campbell leaned forward in his chair
as Fields went into detail about the
story the real estate dealer told of the
mysterious stranger with the wart on
