SUGGESTIONS TO BEGINNERS 267 
For example (Fig. 60) all the pigs in the first litter would 
have a nip taken out of the lower edge of the left ear next to the 
head, which represents No.1. No, 2 is indicated by taking a nip 
out of the lower edge of the left ear half way between the base 
and the tip; and the pigs in the third litter have a nip taken 
out of the tip of the left ear, and so forth. Between 5 and 10 
two nicks are necessary. Thus, 6=5+1. 7—5-42. 
8=5+ 38. 9=—5-+4. For No. 10, we go to the lower side 
of the right ear next to the head. Larger numbers call for 
various combinations, for example: 11 == 10+ 1. 1210+ 2, 
1710+ 5+ 2, ete. The nick should not be made deep, er 
it will disfigure the ear; just a little deeper than the thickness

Fie. 60.—One method of numbering pigs by means of ear marks. If all the pigs in a 
litter are given the same mark, the large numbers will be unnecessary, except in very large 
herds. 
Fie. 61.—Another method of ear-marking pigs, which some may prefer to the one 
first mentioned. 
of the skin is sufficient. If the piece is cut out cleanly, the 
mark will stay as long as the ear lasts. 
Another method of numbering is as follows: A cut on the 
lower or outer side of the right ear indicates “one,” and 2 
corresponding cut on the left ear indicates “three.” Also, 
a cut on the upper or inner side of the right ear indicates “ ten,” 
and a corresponding cut on the left ear indicates “thirty.” 
Thus No. 2 would be indicated by two cuts on outer side of right 
ear. No. 4 would be 3+ 1. No. 6 would eail for two cuts on 
outer side of left ear. No. T=6+ 1. No. 4830+ 10 
-- 3. Two cuts on inner side of left ear would indicate 60, and 
three cuts would be 90. Thus it will be seen that a great many 
numbers may be indicated by using different combinations of 
cuts. (Fig. 61.)
