H. C. Jones, d.b.a. Jones Construction Company, brought this action under the Miller Act, 40 U.S.C.A. Sec. 270(a), et seq., against Barfield Construction Company, a copartnership composed of Burden Ivy Barfield, Bourdon Ray Barfield, and Oliver Eakle Barfield, and St. Paul Mercury Indemnity Company, a corporation, to recover the reasonable value of labor and material furnished to Barfield at Salina, Kansas, on government contracts. Barfield was the prime contractor on three separate contracts for the improvement and expansion of Smoky Hill Air Force Base and St. Paul executed a payment bond on the three contracts as required by the Miller Act. Jones verbally agreed with Barfield to do the excavating, ditching, earth moving and cushioning work, commonly known as dirt work, required by the prime contracts and was to receive two-thirds of the profits realized on this portion of the work. Barfield was to advance sufficient funds to pay Jones costs and expenses, but a dispute arose as to what items were to be included in Jones costs prior to determination of profits.
