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

"The Common Sand-hopper, <em>Talitrus locusta</em>, which may be met with in thousands upon thousands of European shores, is a well-known example of this family. Although its length is not much more than half an inch, it can leap several inches into the air, and the facility with which it escapes pursuit by burrowing into the soft wet sand is truly wonderful." &mdash; Goodrich, 1859

"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." &mdash; Wells, 1857

"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
