At the outset we start with the Texas rule that doubts in construction of the bond must be resolved against the surety. Fidelity and Deposit Co. of Maryland v. Central State Bank, Tex. Civ.App. 1928, 12 S.W.2d 611, 613; Massachusetts Bonding Ins. Co. v. Texas Finance Corp., Tex.Civ.App. 1924, 258 S.W. 250, error dismissed; First State Bank v. Metropolitan Casualty Ins. Co., 1935, 125 Tex. 113, 79 S.W.2d 835, 98 A.L.R. 1256. But we see no doubt and no reason to import doubt.
