A letter received by the ministry Of ma
Tine speaks doubtfuiiy Of Marconi't exper-
tments. The writer says 0arcoui II en-
gagged upon . certain modification. after
which he viii make second series of ex-
perfments. The findings Of the commits

Fearop, tina French naval attache In Lon
don. 10 chief Of tho commission. He pays
special attention to Narcouis experiments
for his government.
There IL considerable rivalry between
Marconi and Ducrctct. Tho latter speaks
highly Of Marconi. and says his claims are
we'll founded. But he writes me: s'The
establishment Of the principle and prde-
tice Of automatic registration Il entirely
mine. Numerous experiments have demon
stratsd Its success"
Tho French government does not Of
ncially favor one rather than the other.
While the French commission has been
examining Marconis claims, Ducretet has
had conferences by invitation with Lock
roy and the marine ministry. and by invi-
tation OF Moujest NJ the ministry Of posts
and telegraphs. Both MINISTERS praise Du-
cretef. but await the findings Of tho COM
mission before pronouncing upon Mar
conf. Mcnjest assured Ducretes that he
hoped soon to have his automatic Morse
instrument in every telegraph ONCE In
France.
Automatic Receiver.
When Marconi visited Ducrete. he nd
uitted that the automatic receiver was
the erowninE work Of the previous inves-
LEGATIONS Marconi's experiments have
been made IT sea, and thus encountered
fewer obstacles than Ducretet's, which
hitherto have been made on land. Lieut..
