The National Geographic Magazine, Vol. II., No. 2, May, 1890

A careful survey of river systems opens the journey, using the streams of northern New Jersey as a springboard for a broader classification of waterways. The author examines how rivers align with the underlying slopes that birthed them, distinguishing “consequent” channels that follow constructional gradients from “antecedent” rivers that persist through geological upheaval. By weaving together examples from the Red River of the North to lava‑blocked streams in Oregon, the piece sets a solid framework for understanding river behavior worldwide.

Listeners will be guided through vivid geological storytelling, hearing how ancient uplifts and faulting reshape courses, yet some rivers stubbornly retain their paths. The discussion of revived and superimposed streams, along with insights into the Green River’s puzzling history, illustrates the dynamic dialogue between water and terrain. Even without venturing beyond the first act, the narrative offers a compelling glimpse into the forces that sculpt our planet’s arteries.
