| C2.E.C.M./11.3.29 - 2 - of the radiator, as per enclosed sketch, on which I fully reported at the time. It is certainly a fact that without this scheme we were unable to carry through these trials without complete engine failure owing to loss of water. I thought this information might be useful in evolving some scheme as suggested by Mr. Royce. I admit it is only a temporary scheme, but I submit that it was an occasion when an emergency had to be met by some emergency action. In noting the behaviour of cars in America as regards the boiling and loss of water, I certainly did appreciate the fact that most of the cars boiled when run under the same conditions as the R.R. Cars I was testing, but did not appear to lose the same amount of water. Has R. {Sir Henry Royce} considered the Cadillac scheme where the overflow from the radiator passes through a condensing tank, in the frame there being no air vent to the radiator, so that when cooling down, the water is drawn back to the radiator from this condensing tank.
