Everton’s experiments with an electrical device to combat frost have proved a success. A portion of the practice ground had been laid with wires inches under the surface, and when the electrical current was switched on combated the cold. There were nine degrees of frost on Merseyside last Wednesday night, and on Thursday the Everton ground was frostbound, with the exception of the treated 18 squares yards. There the grass was green and soft.
