Excerpt from The Mechanical Composition of Wind Deposits, Vol. 1 The great lightness of the air, when compared with water, and the comparatively high velocity of its currents will necessarily render any materials it may carry and deposit somewhat different in composition and structure from those which are laid down in water. They are as a rule finer, they exhibit a different bedding and are more capriciously placed. These characteristics are familiar in a general way. It is here desired to present more exact information on this subject, particularly as to the mechanical composition of these deposits, and to show how this changes under varying circumstances of deposition. It is hoped that this may lead to a more certain identification of wind sediments, wherever the may be found. The inquiry seems to be of special importance in connection with the study of superficial deposits. Samples of different kinds of materials moved by the wind have been collected from different places of desposition and from the atmosphere directly for this study.
