Chap. XX. BY SEMI-CIVILISED PEOPLE. 189 



" for instance, are fit for use, he takes ten or twelve that he 

 " most approves, and plants them at least 100 yards from 

 " others that blossom at the same time. In the same manner

In the great work on China published in the last century 

 by the Jesuits, and which is chiefly compiled from ancient 

 Chinese encyclopedias, it is said that with sheep " improving 

 " the breed consists in choosing with particular care' the 

 " lambs which are destined for propagation, in nourishing 

 " them well, and in keeping the flocks separate." The same 

 principles were applied by the Chinese to various plants and 

 fruit-trees. 43 An imperial edict recommends the choice of 

 seed of remarkable size ; and selection was practised even 

 by imperial hands, for it is said that the Ya-mi, or imperial 

 rice, was noticed at an ancient period in a field by the Em- 

 peror Khang-hi, was saved and cultivated in his garden, and 

 has since become valuable from being the only kind which 

 will grow north of the Great Wall. 49 Even with flowers, 

 the tree pgeony (P. moutan) has been cultivated, according to 

 Chinese traditions, for 1400 years; between 200 and 300 

 varieties have been raised, which are cherished like tulips 

 formerly were by the Dutch. 50 



Turning now to semi-civilised people and to savages : it 

 occurred to me, from what I had seen of several parts of South 

 America, where fences do not exist, and where the animals are 

 of little value, that there would be absolutely no care in 

 breeding or selecting them ; and this to a large extent is 

 true. Eoulin, 51 however, describes in Columbia a naked race 

 of cattle, which are not allowed to increase, on account of 

 their delicate constitution. According to Azara 52 horses are 

 often born in Paraguay with curly hair ; but, as the natives
