PECULIUM, civil law. The savings which were made by a son or slave with the 
consent of his father or master. Inst. 2, 9, 1; Dig. 15, 1, 5, 3; Poth. ad 
Pand. lib. 50, tit. 17, c. 2, art. 3. 
     2. A master is not entitled to the extraordinary earnings of his 
apprentice, which do not interfere with his services so as to affect his 
master's profits. An apprentice was therefore decreed to be entitled to 
salvage in opposition to his master's claim for it. 2 Cranch, 270.
