Had the Works been able to spare Mr Bailey for a further length of time we might have made more progress, wise or otherwise, with these two pieces of work. As it is I must leave them for another part of the chassis which I hope to tackle on the arrival of Mr Spinney here about next Wednesday, the 24th April. Mr Bailey has the re-arrangement of the lubrication of the small pump to attend to which does not need my attention. He also brought with him a design of a very much larger air pump with a view to pumping tyres, but I think it would be very undesirable to have this much larger air pump always running with its multiplicity of connections and hence risk of failure for the sake of being able to pump a tyre occasionally. You will remember that I pointed out to you that I thought this question should not have been introduced as it has been the cause of much brain fag, and useful time has been wasted. In connection with this air pump question it should be borne in mind that tyres are rarely now pumped on the road, and that all garages are usually supplied with an efficient pump, so that the need of carrying such an apparatus is very small and should only be considered when compressed air is being used for other purposes, such as self-starting.
