Here the grain was threshed and winnowed. They then winnowed the grain/chaff mixture. It is threshed and winnowed after being dried for approximately one week. A stripper-harvester also winnowed the grain, removing the chaff. Once the grain was winnowed, it was ground using a millstone, to create flour. The nuts are then dried, shelled, and winnowed, usually by hand. Later, the field was winnowed down to just Mondale, Hart and Jackson. Sometimes it needed to be winnowed several times. I've winnowed my crowd down to a select few who can support me. A lag deposit is the deposition of material winnowed by physical action. Harris would be "winnowed out" just over a month later.
