Dry-Blowing. If no water can be obtained, it is sometimes profitable to concentrate pay-dirt by winnowing, tossing it in a pan until the lighter particles have been blown away, and finishing with mouth-blowing. It is of course a wasteful method of concentration.

Dry blowing is not the most efficient form of gold recovery and I am sure some fine gold will not make it into the hopper. I am not too concerned by this as I don't go out to get of the fine gold.
