The creation of grain elevators made it necessary to switch from measuring grain by bushels to measuring it by weight. If you look at the photo in the previous post of the Cracker Jack Company building, you’ll notice a large, flat area to the side. That was the bed of the scale used to weigh wagons as they arrived, to determine how much grain they carried. The wagon would be drawn up so it sat on that bed, and then the clerk would go into the scale house to check the weight.
The weights and measuring device, shown above, were inside the scale house. Once a wagon was situated on the wooden platform (just outside the window behind the scale), the clerk would check the weight on this scale, deduct the known weight of the wagon, and record the amount in the book, along with the price that would be paid for the corn.
