3/24 An iron that stood the ordinary test of a wet finger was too cold for Joe and Martin, and such test was useless. They went wholly by holding the irons close to their cheeks, gauging the heat by some secret mental process that Martin admired but could not understand. When the fresh irons proved too hot, they hooked them on iron rods and dipped them into cold water. This again required a precise and subtle judgment. A fraction of a second too long in the water and the fine and silken edge of the proper heat was lost, and Martin found time to marvel at the accuracy he developed--an automatic accuracy, founded upon criteria that were machine-like and unerring. |
