| GRY{Shadwell Grylls} See mc WHITE STAR LINE ON BOARD M.V. "BRITANNIC" Sunday Jan 7th. whether it was caused by the thrust on the splines as we previously suspected.

Most of the American 2/plate clutches do not seem as compact as they might be. Even with the fully balanced shaft there is Hs{Lord Ernest Hives - Chair} We ought to reach N.Y. tomorrow, Monday, shortly after noon. Re Bentley thrust race.
