56 HEREDITY IN RELATION TO EUGENICS 





Fig. 24. — Pedigree of family with mechanical and inventive ability, par- 

 ticularly in respect to boat-building. I, 2, a suicide: II, 1, a suicide. His 

 brother, II, 5, a builder of swift boats and yachts, II, 7, insane; II, 8, eccentric. 

 The union of these two strains with evidence of nervous instability resulted 

 in a family of 9 children and 18 grandchildren. Four of the sons show a high 

 degree of inventive abiUty and 2 of these III, 8-12, developed the genius 

 of their father in designing and building swift and beautiful boats. Three 

 are musicians. III, 10, 11, 17, and one of them. III, 11, shows also mechanical 

 ability. In the next generation these traits reappear in the various frater- 

 nities. IV, 1, is a musician; 2 has much mechanical skill and 3 is inventive; 

 5, is a builder of fine boats; IV, 11-15 represent 5 boys, none over 22, but 

 already designing boats; two other daughters of this generation show artistic 

 and musicial talent and, finally, in the next generation we have a girl of 14, 

 V, 3, designing boats. F. R.; H.

 inherited capacity from ancestry more or less remote, devel- 

 oped for generations under some unconscious cerebration.^' 

 There was Seth Pomeroy (1706-1777) an ingenious and skill- 

 ful mechanic who followed the trade of gunsmith. At the 

 capture of Louisburg in 1745 he was a major and had charge 

 of more than twenty smiths who were engaged in driUing 

 captured cannon. Other members of the family manu- 

 factured guns which in the French and Indian wars were 

 in great demand and in the Revolution, also, the Pomeroy 

 guns were indispensable. "Long before the United States 

 had a national armory, the private armories of the Pomeroys 

 were famous. There was Lemuel Pomeroy, the pioneer 

 manufacturer of Pittsburg, stubborn but clear headed, of 

 whom a friend said: There would at times be no living
