EX-ISsPECTOR BERRYMAN'S ALLEGATIONS
AGAINST INSPECTOR MATTHEWS.
Mr.. Bergman, formerly an inspector of boil
ors ana as such associated for time with Inspector
Matthews made sundry charges against tue latter, in
tie course Of the examination yesterday, reported
above. The most serious that Mr. Matthews
had forged Mr.. Btrrymaus signature to the certii-
cate OF inspection given the steamer North America
in January, 1867 previous to a voyage Rio de Jancro
MI Bergman testified under oath that upon his refusing
to give the certificate, Mr.. Matthews intcrposed, and
SAID that he would give it. Mr.. Bergman then, he
stated returned to the Inspectors Office and directed
the clerk not make out certificate for the vessel
But he subsequently found that such certificate had
been placed file at the CustomOusc, and that bore
forgery ot Lis signature, which forgery he believed,
having been informed, had been committed by In
spectOr Matthews.
Mr. BERGMAN yesterday afternoon accompanied
TRIBUNE reporter, at the instance of the latter to the
Custom House to examine the papers in the Sow
era of the principal clerks in the Auditors Office joined
the examination OF the various signatures brought
into question. Mr. Berrymans signature a. attached
N H. rent certificates found to have been written
by yarious hands other than his own-usually by the
clerk who filed mp the body Of the certificate. The name
OF Mr.. Bergman was attached TO the certificate
Of the North America; hut II was uDanl-
mously pronounced TO have been written Isithcr by
himself, by the clerk, by Mr.. Matthews speci
mems of the handwriting O each having been compared
with IT, Mr.. bergman admitted that he sometimes di-
Tcccd the clerks sign his name for HIM. Upon inquiry
az the Inspectors Office, in Pucs, It was as'erianrd
ne inspectors commonly dryt me ,iefh 10 5lSh
TIER names for them; ard that the nOc5 before whom
Tie oahs taken receive such signature in lieu of gen
unc ones THIS abuse j. admitted to be OF long standing
MI Bergman also exhibits list of six or ciTt steamers
which al various times refused certificates by him.
LdJ received them from Mr.. Mathews He asserts that
Ihc latICr was actuated by Interested motives
incidentally, also, his statements tend 10 show
mat great disqualification exists in the inspection
wee lis testimony appears TO be lightly regarded by
