Pierce Butler, Willard Sutherland Company v. United States…
“ The forms of bid indicated a purpose to contract in advance for the year's supply and not to buy coal in the open market; they informed bidders that the stated quantities were estimated on the basis of previous purchases and were not to be taken as exact figures, and such forms were suitable to enable the department to award one contract for the total estimated quantity or to distribute its requirements among a number of producers as it might determine. Appellant's bid mentioned specifically 10,000 tons (which was only one-sixtieth of the estimated total for Hampton Roads) . ”
