On 26 April 1841 Law contracted with the trustees of the Nauvoo House Association to build the Nauvoo House “after the manner, size, order, and finish; expressed in the specification[s],” which appear to have been supplied by Woodworth. At some point Woodworth apparently took over Law’s responsibilities. (Nauvoo House Association, Agreement and Specifications, 26 Apr. 1841, CHL.)
