The German engineer H.A. Janssen gave one of the first accounts of the often peculiar behavior of granular material in a paper published in German in 1895. From simple experiments with corn he inferred the saturation of pressure with height in a granular system. Subsequently, Janssen derived the equivalent of the barometric formula for granular material from the main assumption that the walls carry part of the weight. The following is a translation of this article. The wording is chosen as close as possible to the original. While drawings are copied from the original, figures displaying data are redone for better readability. The translation is complemented by some bibliographical notes and an assessment of earlier work, wherein Hagen predicted the saturation of pressure with depth in 1852, and Huber-Burnand demonstrated that saturation qualitatively as early as in 1829. We conclude with a brief discussion of more recent developments resting on Janssen's work.

- Cohesive, frictional powders: contact models for tension (2008, background): “(If the walls would be frictional, the pressure from a certain wall would not be transferred completely to the respective opposite wall, since frictional forces carry part of the load – an effect that is known since the early work of Janssen [23; 77; 86].)”
- Shear thickening in concentrated suspensions: phenomenology, mechanisms and relations to jamming (2013, background): “These include the effective coefficient of friction (Janssen, 1895; Sperl, 2006), the contact angle for wetting, as well as factors related to particle geometry.”
- The role of dilation and confining stresses in shear thickening of dense suspensions (2010, background): “Instead the stresses are related by a coefficient of order 1 (Janssen, 1895; Sperl, 2006).”
