| We get a very bad quivering of the propeller shaft when the clutch is engaged slightly. We are at the moment fitting up a can to take consumption at various speeds the results of which we will let you have at the earliest possible moment. We received your telegram: Use thermometer off Bensport Pistons will be ready Wednesday next Robotham. We had already got the thermometer in operation off the Bensport. I telegraphed not knowing how soon Mr. Dodd would be returning. G.W.H. Hancock G.W.H. | ||
