Numerouslarge bubbles of air came up, and after a timethe bottle was gripped and held pretty tightly bythe sand. Near by was an alluvial fan, or delta-like deposit, where the sand was purer, containingmuch less admixture of fine, earthy particles. Ithad flowed with less formation of broad wealdsand more of the longitudinal ridges already de-scribed, which are due to the rapid separation ofsand from water. In this deposit I inserted theplunger and worked it up and down as bubbles of air came up, but they were fewin number and small in size. I should add thatin both cases the working of the plunger produced.
