If it is also desired to assort the cards accordingto age groups, for example, the binding posts of the switchboard representing such groupsare connected with the clips into which the sorting bos plug fits. The circuits being thuspiepared, when a card is placed in position in the press, and the handle of the pin box isdepressed by the operator so that the circuit is closed through each hole in the card, notonly will the registration be effected on the counting dials, but the sorting box that has beenselected for a given age group is opened. The operator releases the handle, removes the carddeftly from the press, deposits it in the open sorting compartment with her right hand andpats th
