SCIENCE IN THE INDUSTRIAL WORLD 



matrix rests. The metal is forced against the matrix, 

 which is filled first, and then instantly occupies the body 

 of the mold under pressure, insuring a good cast. When 

 chilled, the types are ejected through the mold into the 

 carrier, which carries them to the line in the galley. 

 As each line is completed, it is advanced automatically 

 to make room for the next. The correction of matter 

 set on the Lanston machine is the same as in hand com- 

 position; it is not necessary to recast a line, as hi the 

 slug machines. 



"It should be observed that the keyboard and cast- 

 ing machine have no connection whatever, and that 

 each part can be operated independently. A keyboard 

 operator can set matter as rapidly as he can read the 

 copy and. strike the keys, a speed of 5000 ems per hour 

 being regarded as a moderate average. The type- 

 casting machine casts and produces, according to the 

 body size, from 75 to 125 ems per minute, or from 4000 

 to 5000 per hour." 



From this it will be seen that this machine is a marvel 

 of ingenuity. Yet, despite its complexity, it is entirely 

 practical, and is undoubtedly the favorite composing 

 machine at the present time. It may interest the reader 

 to know that the pages of the present volume were com- 

 posed on Lanston machines. The beauty and clearness 

 of type and the evenness of justification speak for 

 themselves. 



THE GEAPHOTYPE 



The Lanston has a rival, however, that has recently 

 been placed upon the market, which is so simple, and
