60 to protect him from accidental splashes of melted metal. Then, with his right hand, he took from the melting pot a spoonful of the hot metal, which he quickly poured into the jet or mouth of the mould. At the same instant, with a sudden jerk, he threw up his left hand, so as to aid the melted metal in making a forcible splash against the matrix at the bottom of the mould. This sudden jerk or throw was needed, in the casting of small letters, to make a good face to the type. If it was not done, the metal would cool too quickly, and would not penetrate the finer lines of the matrix. Long practice enabled the type-caster to do this work with apparent carelessness; but the trick of making this throw or cast with the left hand, at the right time and in the right manner, was slowly acquired—by some strong men, never acquired at all. In all cases, hand-casting was hard work. To face types, writes August Bernard, the type-caster must make the contortions of a maniac. It was slow work. Fournier the younger, writing in 1764, says that the performance of the type-caster of ordinary book types would vary from two thousand to three thousand types per day. When this throw was made, the type-caster removed the matrix with his right hand, and, giving the mould a toss, threw out the type. The matrix was then replaced on the mould, and the operations which have been described were repeated in the casting of every subsequent type.

It must be confessed that this method of making types is not simple. It is too circuitous in its processes, and too complex in its machinery, to be regarded as the fruit of the first lucky thought of the inventor. It is a scientific process, manifestly the result of thought and protracted experiment. In its series of impressions, it is an emblem of the art which it has created. The counter-punch impresses the punch, the punch impresses the matrix, the melted metal impresses the matrix and mould. One model letter on the punch is the instrument by which millions of types are made; one letter on a type may serve in the printing of millions of words.
