This case is before the Court for the second time. As a result of the first appeal the Court remanded the case for a redetermination of damages.
See
Slay Warehousing Co. v. Reliance Insurance Co.,
Missouri law governs the issue and the relevant statute reads as follows: Creditors shall be allowed to receive interest at the rate of six per cent per annum, * * * for all moneys after they become due and payable, on written contracts.
Mo.Rev.Stat. § 408.020 (1949). The Supreme Court of Missouri consistently has held the statute requires an award of pre judgment interest where the amount due is readily ascertainable though not strictly liquidated.
See
Denton Construction Co. v. Missouri State Highway Commission,
Thus the issue for this Court becomes whether the amount due under the insurance contract was readily ascertainable. On July 1, 1965 plaintiff made demand upon defendant for a sum repre

senting an amount expended in salvage operations, initiated in an attempt to mitigate damages that resulted from an accident covered under the defendant’s policy. Although the sum demanded was far in excess of the sum finally stipulated as owing, the supporting statements that accompanied the July 1, 1965 demand provided a basis to ascertain the amount owed appellants; therefore, the statute applies and prejudgment interest must be paid from the date of demand.

Reversed and remanded.
Notes
. “On principle there is no reason for denying interest when the action is in
quantum meruit
and the claim is unliquidated in the sense that the amount is to be measured and determined by the standard of the reasonable value of the services * * * If the defendant is liable * * * he is under a legal duty to liquidate the sum due and interest should be allowed from the time when he should have paid.” Laughlin v. Boatmen’s National Bank,
