Defendants offered to read a paper, as an original deed. Its execution was denied, and was not proved. They also proposed to prove a conveyance, by parol evidence of the contents of a lost deed, the execution of which was not proved. Before the former deed could be read, or the evidence of the contents of the other could be received, it was necessary to prove that the papers were deeds. There was no such proof.

No such authorization was proved. Judgment on the default.
