There are several varieties in cultivation, varying in the degree of hardihood, time of ripening, thickness of shell, size and other particulars.
Already in the 7th century B.C., when Hellenism was still in a rudimentary stage, the citizens of the Greek city-states had been known to the courts of Babylon and Egypt as admirable soldiers, combining hardihood with discipline, and Greek mercenaries came to be in request throughout the Nearer East.
The breeds include the Ayrshire, noted milkers and specially adapted for dairy farms (which prevail in the south-west), which in this respect have largely supplanted the Galloway in their native district; the polled Angus or Aberdeen, fair milkers, but valuable for their beef-making qualities, and on this account, as well as their hardihood, in great favour in the north-east, where cattlefeeding has been carried to perfection; and the West Highland or Kyloe breed, a picturesque breed with long horns, shaggy coats and decided colours-black, red, dun, cream and brindle-that thrives well on wild and healthy pasture.
It was this constant warfare with the Indians and the necessity for hard continuous work, owing to the lack of precious metals in Chile, that no doubt helped to produce in the settlers the strength and hardihood of character that distinguishes the Chileans among South American races.
(I) Setting aside differences of constitution, such as hardihood, size, and the like, there is relatively little variation in the form of the organs of vegetation.
