LESSER KNOWN BREEDS OF SWINE 461 
The introduction into England of these Chinese, Nea- 
politan and Siamese pigs wrought a revolution among the 
earlier types of swine, and the crossing and inter-crossing 
of various types, which followed the introduction of foreign 
blood, and which is too intricate and too little known to 
admit of complete investigation, resulted eventually in the 
English breeds of the present day. 
Chinese, Neapolitan and Siamese swine were also im- 
ported into the United States. The great bulk of Ameri- 
can foundation stock came from Great Britain, especially 
England, and as was the case in England, the use of 
Chinese, Neapolitan and other similar blood, followed by 
the crossing of various local types, has led to the establish- 
ment of what are known as American breeds. 
586. Chinese swine. — Youatt writes of these swine as 
follows: ‘‘ There are two distinct varieties, the white and 
the black; both fatten readily, but from their diminutive 
size attain no great weight. They are small in limb, 
round in body, short in the head, wide in the cheek, and 
high in the chine; covered with very fine bristles growing 
from an exceedingly thin skin; and not peculiarly svm- 
metrical, for, when fat, the head is so buried in the neck 
that little more than the tip of the snout is visible. The 
pure Chinese hog is too delicate and susceptible to cold 
ever to become a really profitable animal in this country 
(England); it is difficult to rear, and the sows are not 
good nurses, but one or two judicious crosses have in a 
manner naturalized it... . Many valuable crosses have 
been made with these animals; for the prevalent fault of 
the old English breeds having been coarseness of flesh, 
unwieldiness of form, and want of aptitude to fatten, an 
admixture of the Chinese breed has materially corrected 
these defects.’ Youatt’s description is so clear that it
