Notes to figures on pages 143 and 145.

In the original magazine the legends above the pushbuttons are almost
readable; but I haven't been able to make them legible in the scanned copy.
So here they are:

Figure 7, p. 143

TOP ROW - all blank
2nd ROW - NAPR WOOD WINN HAMD LOMB BLUE GARY CHEA CHHS CHRN CHMF CHVB
   CHIP CHLU CHAR
   and there is some word under each of these that I can't make out.
   possibly CONC
3rd ROW - NWYK LOSA KSCY KSCY ST LO INDP MEMP DETR AKRN blank CHGO CHGO
   MILW COLB BSPO
   some of these have words underneath.  Under the two KSCYs it looks like
   1st and 2nd.  Something under AKRN.  Under the two CHGO buttons it looks
   like LOCAL C and LOCAL D.  Under COLB is something.  Under BSPO is
   SPILL OVER.
4th ROW - WUCHGO PHIL WUNYK blank CHWW CHOD BOSN three blanks CHGO CHGO
   and three more blanks.  Under the two CHGO buttons it looks like
   LOCAL A and LOCAL B.

Figure 10, p. 145

TOP ROW - NAPR WOOD WINN HAMD LOMB BLUE GARY CHEA CHHS CHRN CHMF CHVB 
   CHIP CHLU CHAR  and the word that looks like CONC under all these.

2nd ROW - NWYK LOSA KSCY KSCY ST.LO INDP MEMP DETR two blanks CHGO CHGO
   blank COLB BSPO  Under the two KSCY buttons are 1ST and 2ND.  Under
   the two CHGO buttons it looks like LOCAL C and LOCAL D.  Under COLB
   it looks like DAYT, and under BSPO is SPILL OVER.

Most of these abbreviations are recognizable as cities.  Presumably the
CHxx designations are different locations in Chicago, or different departmental
offices in the same location in Chicago.
