shows by its height the percentage of those named for that vocation who mentioned no schooling above the elementary or secondary grade. This would probably mean in most cases that the educational preparation was carried no farther. That portion of the ordinate which has heavy black lines at the sides shows in the same manner the percentage of those mentioned who had received the baccalaureate degree at some college or university; that portion having a heavy line in the center, the percentage who had completed a professional course; that portion which has the heavy lines both at the side and in the middle, the percentage who had pursued both the college and professional course; the portion between the top of the ordinate and the horizontal line at the top of the figure, the percentage educated entirely abroad, and the little line extending out from some of the ordinates, by its distance from the base line, the percentage who had taken some postgraduate degree. 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 52), 35 per cent, have a professional education, presumably, the divinity school (heavy middle line 91—56 35), 20 per cent, have both (heavy side and middle lines 76—56 20), 9 per cent, were educated entirely abroad and were presumably largely foreigners (distance between top of ordinate and top of figure, 100—91 9), 28 per cent, had taken a postgraduate degree
