Torrance of the vessel showed her to deserve. The
trial ended Tuesday night and then the vessel ran to
London. where she anchored until yesterday, and
then came to New York. When the data are worked
out and the reports submitted to the Navy Department

which she was built. Meanwhile she Will remain OF
East Nnth-s where her fittings except her guns and
