" Under the Oklahoma decisions a stipulated attorney's fee is "within the equitable control of the court, and he should allow only such sum as may be reasonable." State v. Chastain, 132 Okla. 44, 269 P. 319; McClain v. Continental Supply Co., 66 Okla. 225, 168 P. 815. Such is the rule in the federal courts.

"Where the evidence is conflicting and the case is submitted under proper instructions to a jury, and the jury under such instructions returns a verdict, where there is any evidence reasonably tending to support the verdict, the decision of the jury is final, and will not be disturbed by this court on appeal." Oklahoma State Bank v. Ward, 127 Okla. 45, 259 P. 644; School District No. 62 v. Morgan, 127 Okla. 193, 260 P. 46; Bossert Corp. v. Holliday, 127 Okla. 214, 260 P. 480; Swindler v.
