To Tell the Age of Swine. 
7b urstenburg, a well known German authority, has given the following 
cummary for determining the age of swine : 
The animal is born with eight teeth— four corner incisors and four 
tusks. 
On the eighth or tenth day appears the second or third temporary 
Kuolar. 
At four weeks old the four nippers appear— two in the upper and two 
in the lower jaw. 
At the fifth or sixth week the foremost temporary molars appear in 
the upper and lower jaw. 
At the ago of three months the. intermediary incisors have appeared 
above the gums. 
At the sixth month the so-called wolf’s teeth will have appeared ; and 
at the same age appear the third permanent molars. 
At the ninth month the following teeth will have appeared : namely 
the permanent corner incisors, the permanent tusks, and also the second 
permanent molars. 
At the twelfth month the permanent nippers will be in view. 
With the twelfth and thirteenth months the three temporary molars 
will have been shed, and their permanent substitutes, which, at fifteen 
months of age, will have fully appeared, ax-e now just cutting through 
the gums. 6 
With the eighteenth month the permanent intermediary incisors and 
the hindmost permanent molar will have made their appearance j and, 
With the twenty-first month, they will be fully developed. 
Importance of Swine to Man. 
Next to cattle, swine are the most important to man as an article of 
food. In the adaptability of pork for successfully standing long voyages 
either barreled or smoked, in the value of lard for various culinary, lubril 
eating and burning purposes, its place could not easily be supplied now. 
As showing the importance of swine breeding in the United States,

1871— 29,457,500,
