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 prepara-

 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 dis- 

 tance from the base line, the percentage who had taken some postgradu- 

 ate degree. Honorary degrees are not included. In every case, the per-

eentages 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 mid- 

 dle 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
