"A sandy stratum, a a, acting as a filter, occupies an inclined position between two other strata impervious to water, such as clay, the water being absorbed by the superficial parts of the strata, as at a a (which may be of very great extent), will penetrate through its whole depth, and, finding no egress below on account of the basin-like form of the stratum, or from its resting at the lower termination upon a compact rock, will accumulate." — Wells, 1857

During the prevalence of the simoom, particles of fine sand are carried into the atmosphere and obscure the light of the sun. Becoming intensely heated, these particles, by their radiation, increase the temperature of the air, which sometimes rises as high as 120 degrees or 130 degrees Fahr. When powerful winds prevail, dense clouds of sand are carried about in the atmosphere, producing the so-called sand storms. The sand-drifts which are thus formed constantly change their position.

"From one end of a scale-beam, suspend a cylindrical metal bucket, b, with a solid cylinder, a, that fits accurately into it hanging below. Conterpoise with weights (shot or sand) in the opposite scale-pan. Immerse a in water, and the counterpoise will descend, as if a had lost some of its weight. Carefully fill b with water. It will hold exactly the quantity displaced by a. Equilibrium will be restored." -Avery 1895

"Procure an open organ-pipe, at least one side of which is made of glass. While the pipe is emitting its fundamental tone, lower a small ring with a paper bottom, on which a little fine sand has been strewn, as shown. Just inside the upper part of the pipel, the sand dances...its motion becoming less energetic as the ring approaches the middle of the pipe." -Avery 1895

"Support, as shown, a glass or brass plate, square or round, and strew it evenly with fine sand. Place the finger at any point of the edge of the plate, so as to form a node there, and draw a violin bow at a point properly chosen. The sand immediately begins to dance on the plate and arrange itself along nodal lines. By changing the nodal points and bowing properly, other sand-figures may be produced, one of which is shown." -Avery 1895
