shows by its height the percentage of those named for that vocation who mentioned no schooling above the elementary or secondary grade.

Honorary degrees are not included. In every case, the percentages

are to be read by means of the scale at the right and left of the figure. As an illustration of the interpretation of one of the ordinates ] will take that for clergymen: 24 per cent, are shown to have no education above the high school (black portion), 52 per cent, have a college education (heavy side lines 76—24 ${\displaystyle =}$ 52), 35 per cent, have a professional education, presumably, the divinity school (heavy middle line 91—56 ${\displaystyle =}$ 35), 20 per cent, have both (heavy side and middle lines 76—56 ${\displaystyle =}$ 20), 9 per cent, were educated entirely abroad and were presumably largely foreigners (distance between top of ordinate and top of figure, 100—91 ${\displaystyle =}$ 9), 28 per cent, had taken a postgraduate degree
