To I[srael?] S. Piper 
Dear Sir May 28. 1858.
Yours of the 20th. inclosing copy of notice to send out a dedimus &c. was received only yesterday. If, at the time of selling you the Bill of iron the plaintiffs agreed to insure it, and did not insure it,Page 456 and you lost in consequence, you could set off the damage against their Bill, if you could prove the facts. But you can not be allowed to prove anything by Shoup.  He was a party to the contract---is now a party to the suit; and no arrangement between you and him can make him a competent witness. Yours Respectfully
