KEEPING ACCOUNTS. 241 



It is a general rule that all guarantors of commercial pa- 

 per must be immediately notified of its dishonor. 



It is, of course, not necessary to protest a due-bill, or a 

 promissory note, which is still held by the person to whom 

 it was originally given. 



When a note is made payable " on demand" it is neces- 

 sary to make a demand before it will bear interest or can be 

 sued for.
