| - 2 - So far, the radiator that Messrs Firths are running on their car is going quite well. They have one or two other cars of different makes similarly fitted, which also appear to be doing well. The colour effect, and the fact that they do not tarnish under any condition, is a very distinct advantage, and has to be seen to be really appreciated, as under weather conditions of any description, even in Sheffield, the material is unaffected, and all that is required is to wash off any mud which may splash on to it, or rub it over with a duster.
