In the instant case, the claim is one against the wards themselves, and even under the Supreme Court decision above it would be proper to allege and prove the presentation to the guardian before suit, and her rejection or that of the probate court. In Webber v. Swift Co. (Tex. Civ. App.) 226 S.W. 509, Webber, as principal, and Nye, as surety, executed a written contract whereby goods were sold to Webber, but the amount thereof was not paid. Later, Nye became insane and his wife was appointed guardian.
