Samuel Blatchford, Harvey v. United States (113 U.S. 243…
“ In regard to the view adopted by the court of claims, that the claimants have no right to rely on the testimony of experts introduced by them, but should have kept and produced accounts of the cost and expense of the work, we are of opinion that the claimants cannot be deprived of reasonable compensation for the work they did because the evidence they produce as to the proper amount of such compensation is not of the character referred to, when it does not appear that such evidence ever existed. ”
