32 A MANUAL ON THE HOG. 



porkers than the thoroughbreds, combining the hardiness 

 of constitution of the common sow, and the good fattening 

 qualities and better development of valuable parts peculiar 

 to the boar. 



The thoroughbred boar, having a fixed type, transmits 

 his characteristics with greater accuracy when bred to a 

 common sow, than when a thoroughbred sow of a different 

 breed is used. The common sow, however, communicates 

 her hardiness of constitution and activity to her offspring, 

 and thus gives a hog admirably suited for farm purposes. 



Half-bred boars should never be used as stock hogs, 

 since their type will not be transmitted to their offspring, 

 but thoroughbred boars, on the half-blood sows, give fine 

 results. 



CLIMATE. 



Georgia is embraced between the isotherms of 59 and 

 68, a belt which embraces the extreme southern portion 

 of Europe, a portion of North Africa, and extends across 

 Persia in the western, and China in the eastern, part of 

 Asia. This belt passes through the central part of the 

 area which constituted the natural habitat of the wild hog. 

 They were found in Western Europe far north of this belt, 

 principally in that part which is warmed by the Gulf 

 Stream. The hog belongs to the class mammalia, order 

 pachydermata, genus suidae or sus. All the animals of 

 this order are natives of warm climates, none of the others 

 having been found in modern times as far north as the 

 hog. The elephant, rhinoceros and hippopotamus belong 

 to this order. The hog being, therefore, a native of the 

 warm or more temperate regions of the earth, finds a con- 

 genial home in Georgia. He has, as other domestic ani- 

 mals, been acclimated in nearly every part of the globe 

 inhabited by man, and is now profitable in regions many 

 degrees colder than those inhabited by his wild progeni- 

 tors. The range of mean temperature in Georgia, from
