Appletons' Popular Science Monthly, February 1899: Volume LIV, No. 4, February 1899

In Short

This volume of Appletons' Popular Science Monthly presents a multifaceted late-nineteenth-century compendium of scientific inquiry, social theory, and natural observation. Ranging from public health strategies in urban environments to theoretical debates in philosophy and economics, the collection examines how natural laws govern human society and the physical world. Through essays on urban forestry, toxic geological traps, coolie labor systems, tax diffusion, and prehistoric archaeology, the authors collectively argue for empirical observation as the essential tool for human progress. The work endures as a vivid historical snapshot of Victorian intellectual life, capturing an era when science sought to explain and optimize every facet of existence.

The Story

The volume opens with a pragmatic appeal for public health reform in industrial cities. Dr. Stephen Smith demonstrates that extreme summer heat drives massive mortality spikes in New York City through germ-based zymotic diseases. He argues that planting trees along city streets provides a natural thermal regulator, leveraging the steady internal temperature of living wood to lower ambient air heat and protect vulnerable urban populations.

From civic health, the narrative shifts to epistemological foundation with Professor Wm. Keith Brooks's critique of Mivart's philosophy. Brooks challenges the rigid divide between innate human reason and empirical discovery, suggesting that reason itself may be an evolved physical mechanism subject to scientific investigation. Charles Livy Whittle builds upon this empirical foundation by demonstrating how minute physical observations—such as tracking mud and sand delta formations in tiny rainwater pools—reveal the massive geological forces shaping the earth.

The physical investigation of nature turns perilous in T.A. Jaggar, Jr.'s account of "Death Gulch" in Cache Creek. Jaggar details how an inconspicuous ravine acts as a deadly natural bear-trap, asphyxiating grizzlies, elks, and insects with invisible, noxious volcanic gases. The focus then turns to international labor systems as W. Alleyne Ireland details the regulated indenture of Indian coolies in tropical colonies, framing the strict government oversight, medical care, and fixed wages as a humane solution to agricultural labor demands.

Economic theory takes center stage through the late David A. Wells's examination of tax diffusion. Wells distinguishes between land held for private pleasure and land used as an instrument of production, arguing that taxes on productive land naturally diffuse throughout the economy, whereas direct taxation on exclusive personal enjoyment remains anchored to the landowner. Moving from economic laws to cosmic phenomena, Charles F. Holder describes the ongoing meteoric bombardment of Earth, explaining how scientific consensus shifted away from exploded worlds to recognize meteorites as disintegrated comets sharing historical orbits.

Social and educational structures complete the volume's intellectual arc. J. Novicow tallies the staggering financial and human costs of European warfare, condemning imperialist conquest as economic ruin. Sir J.N. Lockyer outlines the rise of state-supported scientific education and laboratory research in Britain, emphasizing the necessity of training teachers and funding pure research. Prehistoric archaeologist Gabriel de Mortillet examines Neolithic carvings on French dolmens, interpreting ancient bucklers and cupule engravings as humanity's earliest graphic records. Finally, the editorial and review sections grapple with sociologists like Franklin H. Giddings over the origins of social cohesion, while re-evaluating Ralph Waldo Emerson's poetic adoption of evolutionary theory against the precise demands of scientific rigor.

How It Unfolds

Greening the metropolis Dr. Stephen Smith presents statistical evidence linking summer heatwaves to high city mortality rates, proposing tree planting along New York streets to stabilize urban temperatures.

The mechanism of thought Professor Wm. Keith Brooks analyzes Mivart's scientific theories, questioning whether human innate reason is an absolute truth or a physical phenomenon that science can study and improve.

Lessons in a puddle Charles Livy Whittle illustrates scientific observation by demonstrating how small streamlets entering static pools form deltas, revealing the core laws of erosion and sediment deposition.

The lethal ravine T.A. Jaggar, Jr. documents the discovery of Death Gulch, where heavy pockets of suffocating volcanic gases kill large animals without leaving signs of physical trauma.

Managing tropical labor W. Alleyne Ireland outlines the legal and medical framework governing Indian coolie transport and plantation work, arguing that regulation protects laborers while securing colony production.

The spread of taxation David A. Wells details the law of tax diffusion, demonstrating that taxes placed on productive capital shift to the consumer, whereas taxes on private enjoyment remain with the owner.

Cosmic bombardment Charles F. Holder examines the composition of iron and stony meteorites, showing how modern astronomy proved these falling space rocks originate from broken cometary orbits.

The ruin of conquest J. Novicow calculates the catastrophic financial losses caused by centuries of European military conflict, arguing that imperialism wastes wealth and hinders social evolution.

Training the scientists Sir J.N. Lockyer outlines British national efforts to train science teachers and secure laboratory funding, calling for expanded opportunities for original student research.

Carvings in stone Gabriel de Mortillet analyzes prehistoric rock engravings on French megaliths, interpreting tomb symbols, bucklers, and carved cupules as France's oldest historical documents.

Debating the social mind The correspondence section features Franklin H. Giddings defending his sociological theory of "consciousness of kind," while editors critique Ralph Waldo Emerson's poetic treatment of evolution.

The People

• Dr. Stephen Smith: A public health advocate who seeks to reduce urban summer deaths by cultivating trees across New York City to regulate street temperatures and absorb disease-causing moisture.
• Prof. Wm. Keith Brooks: A biologist and reviewer who aims to reconcile empirical scientific observation with philosophical theories of human reason, arguing against short-cut a priori assumptions.
• Charles Livy Whittle: A science educator who demonstrates that attentive observation of trivial natural events, like mud settling in a puddle, reveals the grand principles of geology.
• T.A. Jaggar, Jr.: A field researcher who investigates the mysterious animal deaths in Death Gulch, identifying lethal gas accumulation as the cause of asphyxiation in wild animals.
• W. Alleyne Ireland: An author examining tropical labor who seeks to justify the indentured coolie system by highlighting government transport safety, medical inspections, and guaranteed minimum wages.
• Hon. David A. Wells: A late economist whose work clarifies how taxation on productive property diffuses through the market, contrasting it with non-diffusing taxes on personal consumption.
• Sir J.N. Lockyer: An educator and scientist advocating for increased state support, modern laboratory space, and dedicated research scholarships for British science students and teachers.
• Gabriel de Mortillet: An archaeologist who documents Neolithic megalithic engravings, working to catalog and preserve ancient stone sculptures as the earliest written records of France.
• Franklin H. Giddings: A sociologist who writes in to defend his use of "the consciousness of kind" as the foundational psychological principle of human social organization.

In Its Own Voice

Context: Dr. Stephen Smith explains how living trees maintain a stable internal temperature regardless of external weather extremes.

"Since, then, trees maintain at all seasons a constant mean temperature of 54° F., it is easy to see why the air in contact with the forest must be warmer in winter and cooler in summer than in situations where it is deprived of that influence."

Context: The magazine's editor critiques Ralph Waldo Emerson's poetic approach to natural science and evolution.

"The doctrine of evolution is not at war, we trust, with poetic inspiration; but if it teaches anything, it teaches that the world is full of infinite detail, and that without a certain mastery of details general views are apt to be more showy than solid."

Context: Gabriel de Mortillet describes the crude artistry of prehistoric builders carving hard stone monuments in ancient France.

"The engravers of this period were not artists, but stone-cutters, working upon a very hard rock with very poor tools."

What It's Really About

The volume explores the tension between empirical scientific discipline and unverified theoretical speculation. Across varied fields—urban planning, geology, economics, and sociology—the contributors argue that real human progress depends on rigorous, detailed observation of the physical world rather than poetic intuition or abstract philosophy. Whether analyzing how taxes spread through a commercial economy, how streams build deltas, or how trees cool ambient air, the issue asserts that natural laws govern both physical and social structures. Beneath its diverse topics lies a fundamental question: can human society organize its cities, labor systems, and educational institutions in harmony with observable natural laws to ensure public health, economic stability, and intellectual growth?
