It is a familiar principle, that a guarantor is not liable beyond the express terms of his undertaking, and a change in those terms, by which a conditional undertaking shall be made absolute, is such a material alteration as will avoid it.
Here, Newlan guaranteed * the collection of the note. This required the party should make some effort to collect the note, for, although a party may be insolvent as to his general liabilities, it may be in his power to pay a particular note.
By cutting off the words, “ the collection of,” the guarantee becomes an absolute one. This is a material alteration, and avoids the guarantee.

It is not good policy to permit a party interested in such papers, to alter them.
The judgment is reversed, and the cause remanded.
