ceyed through the cable from Newfoundland
On the 9th 7h, 8th 9th and 10th tested the cable at
intervals in four different ways its condition
The following the results
Frstly-Ihere Is fault Of great magnitude at dis
lance Of between 245 and 300 Satutc miles from yaena
but the locality cannot be ascerained
until portion Of the cable twenty or thirty miles in
length has been tested against standard resistance
and until the log has been consulted TO ascertain the
amount Of slack paid out would suggest that the piece
OF cable at Greenwich be carefully measured and tested
against my standard in order TO obtain the correct
estimate Of the distance Of fault assuming, however that

there a fault Offering resistance equal 900 or
900 miles of cable al n distance of about $50
miles from one end Of the 200 miles coil on board tho

This however cannot be the faul, nrst alluded to-
situated at about 30 miles from vacnta-but may have
been the which caused such alarm when tho ships
