Xn general we ©an only assune that toe grooving in the

eospletely leek the segments in place.     Reference to toe attached

we have no samples of segnento as fitted to nodlftod rotor fergings,
naay ©f toe original brass spares show this sane inconsistency in the
grooving depth.

Dear Sir:
Further to my  latter of April l&th in connection
with the defects which have developed in the rotors of the "Princess
of Nanaimo*.
Mill you please write me fully outlining the
prospects of having these rotors repaired in such a manner that wq
will not find it necessary to replace the blading each year at annual
overhaul© This is a situation which cannot be per atted to occur year
after year if there is a solution to the problem* There is some doubt
is my mind that the proper type of propulsion machinery has bean
installed in this ship and I should be glad to hear from you fully in
this connection also*
lours truly.
