270 POLITICAL INSTITUTIONS. 



become better, remind us how, from Homan times down 

 wards, the formation of roads has made larger social aggre 

 gates possible. 



Evidence that a certain type of physique is requisite, was 

 given in 1G ; where we saw that the races which have 

 evolved large societies, had previously lived under conditions 

 fostering vigour of constitution. I will here add only that 

 the constitutional energy needed for continuous labour, with 

 out which there cannot be civilized life and the massing of 

 men presupposed by it, is an energy not to be quickly 

 acquired ; but is to be acquired only by inherited modifica 

 tions slowly accumulated. Good evidence that in lower 

 types of men there is a physical incapacity for work, is 

 supplied by the results of the Jesuit government over the 

 Paraguay Indians. These Indians were reduced to indus 

 trious habits, and to an orderly life which was thought by 

 many writers admirable ; but there eventually resulted a 

 fatal evil : they became infertile. Not improbably, the 

 infertility commonly observed in savage races that have been 

 led into civilized activities, is consequent on taxing the 

 physique to a degree greater than it is constituted to bear. 



Certain moral traits which favour, and others whicli hinder, 

 the union of men into large groups, were pointed out when 

 treating of &quot; The Primitive Man Emotional.&quot; Here I will 

 re-illustrate such of these as concern the fitness or unfitness 

 of the type for subordination. &quot; The Abors, as they them 

 selves say, are like tigers, two cannot dwell in one den ;&quot; and 

 &quot; their houses are scattered singly, or in groups of two and 

 three.&quot; Conversely, some of the African races not only yield 

 when coerced but admire one who coerces them. Instance 

 the Damaras, who, as Galton says, &quot;court slavery&quot; and 

 &quot; follow a master as spaniels would.&quot; The like is alleged of 

 other South Africans. One of them said to a gentleman 

 known to me &quot; You re a pretty fellow to be a master ; I ve 

 been with you two years and you ve never beaten me once.&quot; 

 Obviously on the dispositions thus strongly contrasted, the
