Scientific American, Volume 40, No. 13, March 29, 1879: A Weekly Journal of Practical Information, Art, Science

In Short

This issue of Scientific American serves as a vibrant cross-section of late nineteenth-century industrial progress, scientific curiosity, and economic tension. Published in March 1879, the weekly journal delivers technical reports, commercial dispatches, editorial warnings, and reader inquiries. It details major infrastructure feats alongside workshop innovations, agricultural tools, and laboratory discoveries. Through articles on telegraphy, metallic properties, and legislative battles, the publication captures a rapidly modernizing society. It endures as a primary window into how nineteenth-century inventors, manufacturers, and citizens understood technology and shaped the industrial world.

The Story

The narrative of this issue unfolds through a series of editorial, scientific, and practical dispatches that together illustrate the momentum of the Industrial Revolution. The issue opens with a fierce defense of the American patent system. The editors issue a stark warning against corporate efforts and Congressional legislation that threaten to strip inventors of their constitutional rights and profit guarantees, arguing that such schemes undermine national progress.

Moving from legal battles to public health crises, the text addresses the devastation wrought by pleuro-pneumonia. The contagious cattle plague threatens livestock across the Eastern States, drawing parallels to historic outbreaks in Europe and Australia that caused hundreds of millions of dollars in losses. The issue then pivots toward personal and technological perseverance with a profile of Peter Cooper. The famous industrialist's early struggles in hatting, brewing, and coachmaking highlight how repeated commercial failures ultimately laid the groundwork for his success in machine manufacturing and public life.

Theoretical science and mechanical design take center stage in the middle section. The journal debunks perpetual motion claims surrounding the Gary Motor, demonstrating that its magnetic "cut-off" is merely a standard iron armature. It then reports on M. E. Duter’s experiments presented to the French Academy, which prove that glass Leyden jars physically expand when charged with statical electricity. Applied mechanics are highlighted through a newly engineered double-gyratory ore crusher, while a historical retrospective features Cyrus W. Field reflecting on the twenty-five-year journey to lay the first transatlantic telegraph cable alongside associates like Cooper and Moses Taylor.

Curiosity and international commerce round out the publication's narrative arc. A reader from Iowa submits a detailed query regarding the Decorah ice cave, where ice forms during hot summer days and melts in winter. Reports on European metallurgy trace Berlin's rise as a center for pure aluminum manufacturing, particularly for naval instruments, while identifying the lack of a soldering technique as the metal's main drawback. Comparisons between English and American manufacturing reveal how machine-made domestic hardware outpaces traditional hand-forged British goods in cost and quality. Finally, the issue concludes with an array of classified notices, practical advice, and patent listings, depicting a bustling marketplace driven by steam pumps, iron beams, and continuous mechanical refinement.

How It Unfolds

Defending the inventor The issue opens with a strong editorial condemning legislative attempts to weaken patent protections. It calls on honest citizens and mechanics to defend their constitutional rights against corporate interests seeking free access to patented ideas.

Confronting agricultural peril A detailed report examines the outbreak of pleuro-pneumonia among Eastern cattle herds. The article outlines the severe economic and agricultural risks by tracing the history of similar plagues that depopulated livestock ranges in England and Australia.

Recounting early setbacks A biographical sketch outlines Peter Cooper's varied early career before his manufacturing triumphs. The narrative emphasizes his resilience as he moved from hatmaking and brewing to successful machine work and invention.

Evaluating claims and theories The journal scrutinizes scientific assertions, exposing the Gary Motor's perpetual motion claims as a fundamental misunderstanding of magnetism. It balances this skepticism with M. E. Duter's valid laboratory findings on how electrification expands Leyden jars.

Celebrating global connectivity Cyrus W. Field commemorates the twenty-five-year anniversary of the New York, Newfoundland and London Telegraph Company. He recounts the twelve years of public doubt, financial strain, and persistent effort that preceded the successful laying of the Atlantic cable.

Examining natural and industrial goods Articles survey physical phenomena and global manufacturing, from an Iowa cave where ice freezes in summer to Berlin's production of aluminum nautical instruments. Comparative studies demonstrate how American machine-made locks and latches outperform crude English hand-made hardware.

The People

• Peter Cooper: An inventor, manufacturer, and philanthropist who learned three distinct trades before finding success. He wants to develop useful industrial apparatuses and create viable businesses, but faces political obstacles, changing market demands, and early commercial failures. Ultimately, his persistence enables him to build a lasting legacy as a premier American mechanic and civic leader.
• Cyrus W. Field: The visionary promoter behind the transatlantic telegraph cable. He seeks to establish direct, instant communication between North America and Europe, facing twelve years of public skepticism, failed attempts, and severe financial risk. Supported by a small group of persistent partners, he succeeds in connecting two continents.
• M. E. Duter: A French researcher investigating electrical properties. He aims to prove that charging a Leyden jar causes a true physical expansion of its glass container rather than a thermal fluctuation. By conducting precise measurements with varying flask thicknesses, he successfully verifies his hypothesis before the scientific community.
• American Inventors: A collective group of tradesmen, engineers, and workshop mechanics striving to secure patents and commercialize their devices. They face resistance from short-sighted corporations and Congressional figures seeking to limit license fees, forcing them to actively defend their legal and economic rights.

In Its Own Voice

"The fact that they were able to inveigle one branch of the American Congress into assenting to their unjust and mischievous scheme is one of the anomalies of our recent history."

The editors warn readers that corporate lobbying poses a direct threat to the constitutional rights of domestic inventors.

"Those who applaud our success know little through what struggles it was obtained. One disappointment followed another, till 'hope deferred made the heart sick.'"

Cyrus W. Field reflects on the persistent failures and public skepticism that preceded the successful laying of the Atlantic cable.

"The English 'Norfolk latch,' on the other hand, is ill designed, uncomfortable in hand, clumsily finished, the japan hangs about it in lumps..."

A contributor sharply contrasts traditional British manufacturing methods with the superior, machine-made design of American hardware.

What It's Really About

Beneath its notices and technical descriptions, the journal addresses the tension between raw individual ingenuity and structured industrial power. It argues that technological progress relies on protecting the rights of individual inventors against consolidation and legislative overreach. The text systematically contrasts scientific rigor with popular delusion, using empirical evidence to debunk perpetual motion while elevating precise laboratory research and sound engineering. Furthermore, it reflects a strong sense of national pride, continually demonstrating how American mechanical standards, machine production, and entrepreneurial persistence outpace older European traditions. The underlying theme is a firm faith in practical knowledge as the primary driver of human betterment and national prosperity.

Why Read It Today

This issue appeals to historians, engineers, and general readers fascinated by the mechanics of daily life in the late nineteenth century. Reading it offers an unvarnished, firsthand view of an era when electricity, global telegraphy, and mass production were actively reshaping society. The prose is clean, direct, and authoritative, striking a balanced tone that respects the reader's intelligence while explaining complex physical principles.

The chief difficulty for a modern reader lies in its fragmented, period-specific structure. Because it is a weekly periodical, the text shifts abruptly from legal commentary and deep-sea biological studies to brief patent summaries and commercial advertisements for items like boiler coatings, lawnmowers, and rose bushes. Archaic terminology and long lists of technical specifications require patient reading. However, this varied structure is precisely what gives the issue its vivid texture. What stays with you is the extraordinary enthusiasm for practical problem-solving, capturing a historical moment where every natural phenomenon offered a puzzle to solve and every mechanical task presented an opportunity for improvement.
