RE LIGHTING INSTALLATION AT WEST WITTERINGHenry Royce's home town.

Be sure never to purchase any wires which are not vulcanised. The red flexible that you have sent us I fear is only covered with pure rubber tape. I think you would find that Glovers or the Silvertown Company, would be safe for wires, as they manufacture their rubber from the raw material.

Will you kindly send me 5 yards of high tension wire in one single piece (I have got a few short pieces) and 50 yards of low tension, such as we use on the car, which I always instructed should be tinned wire (because it is easy to solder with resin only) and with plenty of strands of fine copper, so that it is not easy to break; being tinned it is not so easily affected by the rubber or material covering the joint.

Could you replace the red unvulcanised flexible with some which is white and vulcanised, as we want to run it across the ceiling. The difficulty here is that there is much salt in the air, and the salt affects the copper, forming I suppose, chlorides of copper.

Would you please send 50 yards of double flexible suitable for electric bell work (any colour, white or buff preferred) and this should also be vulcanised.

R.{Sir Henry Royce}
