54 were as impracticable in the infancy of the art as they are now. There is no trustworthy evidence that they were ever used for any other purpose than that of experiment.

Every method for making merchantable types, save that of casting, is a failure. Typography would be a great failure, if its types were not cast by scientific methods. This understood, we can see that the most meritorious feature in the invention does not belong to him who first thought of the advantages of types, nor even to him who first made them by impracticable methods. Its honors are really due to the man to whose sagacity and patience in experiment we are indebted for the type-mould, for he was the first to make types which could be used with advantage.

It will now be necessary to explain the scientific method of making types which is practised by every type-founder. The first process is the making of model letters. The work begins with the cutting on steel of a tool which is known as the Counter-punch. The illustration represents the face of a counter-punch for the letter H, of the size usually known among type-founders as Double-English. This counter-punch is an engraving, in high relief, of the hollow or the counter of that interior part of the letter H which does not show black in the printed impression. It has apparently, no resemblance to the letter for which it is made. When the proportions of the counter-punch have been duly approved, it is stamped or impressed to a proper depth on the end of a short bar of soft steel. Properly stamped, the counter-punch finishes by one quick stroke the interior part of the model letter, and does it more quickly and neatly than it could be done by cutting tools.

The short bar of soft steel is known as a Punch. When it has received the impress of the counter-punch, the punch cutter, for so the engraver of letters is called in type-foundries, cuts away the outer edges until the model letter is pronounced perfect. This is work of great exactness, for the millions of types that may be made by means of the punch
