Proceedings of the California Academy of Sciences, Volume III, 1863-1867

In Short

This volume gathers the official proceedings, field notes, and meeting minutes of the California Academy of Sciences between 1863 and 1867. Operating out of rented rooms on Clay Street in San Francisco, a small, devoted band of naturalists, geologists, botanists, and survey workers present their discoveries to one another twice a month. Within these pages, they describe new marine mollusks dredged off Santa Barbara, measure the giant sequoias of the Sierra Nevada, analyze copper and gold ores from booming mining camps, and index decades of regional earthquake shocks. The collection endures as a vivid, primary record of mid-nineteenth-century American scientific practice. It captures the exact moment when disciplined empirical observation began to systematically map the vast, unfamiliar ecology and geology of the Pacific Coast.

The Story

The volume opens in 1863 within the modest rooms of the California Academy of Sciences at 622 Clay Street, San Francisco. The institution, eager to expand its reach across the region, sets out its administrative framework, inviting anyone living within one hundred and fifty miles to join its ranks. The proceedings immediately establish a steady, rhythmic pattern: two Monday evenings a month, a handful of members—sometimes as few as nine or eleven—assemble to present donations to the cabinet, deliver papers, and examine specimens brought in from the field.

In the opening phase, the scientific focus centers heavily on foundational taxonomy and immediate natural history. Botanists like Dr. A. Kellogg present detailed Latin and English descriptions of newly discovered California plants, such as Conyza salicena and Collinsia divaricata. Concurrently, field collectors and state survey members bring in unknown sea slugs, minute land snails, and marine shells gathered along the rocky shores of Catalina Island, Santa Barbara, and San Francisco Bay. The Academy acts as a central clearinghouse where crude physical finds—a pocket of pine cones, a jawbone from a thirty-foot well, or a handful of cretaceous fossils—are given rigorous scientific names and contexts.

As the months progress into 1864 and 1865, the scope of the proceedings broadens from isolated natural history items to major geological and structural investigations. The ongoing work of the State Geological Survey, led by figures like Professor J. D. Whitney, takes center stage. The members tackle the mysterious surface geology of the West, debating the total absence of the Northern drift formation west of the Rocky Mountains—a realization that directly challenges prevailing European and East Coast glacial theories. At the same time, practical industrial science demands attention. Geological surveys of gold-bearing slates, such as the "calico rocks" of Placer County, and detailed tabular surveys of copper lodes in Copperopolis record the intense extraction of natural wealth defining the state's economy.

The mid-section of the volume also turns toward natural hazards and deep time. Members compile exhaustive historical chronicles of California earthquakes, sifting through old mission archives and modern barometer records from 1850 through the severe shocks of October 1865. They catalogue the fossil remains of ancient life, identifying mastodon teeth near Mount Diablo and elephant bones across multiple mining counties, proving that megafauna once roamed the Pacific slopes. Precise trigonometric measurements of the giant sequoias (Sequoia gigantea) are submitted, cutting through popular exaggeration to record the exact heights and girths of trees like the "Mother of the Forest" and "T. Starr King."

In its final movement, covering 1866 and 1867, the horizon expands beyond California's borders. Reports arrive detailing the silver-bearing geology of Nevada's Comstock Lode, the rock salt mountains of the Virgin River, and the structural geology of the Peruvian Andes. The volume culminates in late 1867 with a special assembly called to hear George Davidson and Dr. Kellogg report on their scientific reconnaissance of the newly acquired territory of Alaska. The book closes with comprehensive indices of species, minerals, and topics, marking five years of relentless, collective labor that helped map the natural architecture of the Pacific slope.

How It Unfolds

The institutional call The Academy publishes its operational rules, inviting residents within 150 miles of San Francisco to join, while establishing regular twice-monthly meetings for scientific papers and specimen donations.

Taxonomic foundations Early sessions focus on classifying local flora and marine fauna, with detailed descriptions of new plant species from Contra Costa County and nudibranchs gathered along southern islands.

Geological surveys and industry Presentations shift toward California's economic geology, detailing the state survey's progress, gold-bearing slate quarries in Placer County, and the lenticular copper deposits of Copperopolis.

Catastrophes and ancient life Members present historical catalogues of California earthquakes from mission days through 1865, alongside reports of mastodon teeth and mammoth fossils uncovered in gold-mining gravels.

Measuring the wilderness Naturalists submit precise physical measurements of the big trees in Calaveras Grove, cutting through sensationalism with exact figures for tree heights and trunk circumferences.

Expanding horizons The proceedings stretch far past state lines, examining Comstock Lode tellurium ores, South American Andean geology, and preliminary reports from the 1867 scientific expedition to Alaska.

The People

Dr. A. Kellogg The Academy's librarian and resident botanist, Kellogg is driven by an obsessive desire to document the uncatalogued plant life of the West Coast. He spends his years receiving pressed specimens from mountain glades, describing new species with painstaking morphological detail, and ultimately joining the 1867 survey expedition to Alaska to record its flora.

Professor J. D. Whitney As State Geologist and early President of the Academy, Whitney seeks to bring rigorous empirical science to a chaotic frontier. He constantly pushes the membership to examine grander structural questions—such as mountain elevations, coal formations, and the absence of drift phenomena—standing firm against popular exaggeration and economic speculation.

Dr. James G. Cooper Vice President and active zoologist, Cooper focuses on dredging and gathering marine mollusks, nudibranchs, and land shells from Monterey to the Channel Islands. His work aims to establish a clear geographical distribution of Pacific Coast invertebrate life.

Robert E. C. Stearns A prolific contributor and officer, Stearns is fascinated by conchology, natural anomalies, and fisheries. Whether measuring a giant sunfish in the San Francisco fish market or tracking land snails across local ranches, his goal is total observational thoroughness.

William H. Dall A young, energetic naturalist who uses the Academy as a springboard for major northern explorations. Dall challenges established geographical errors in natural history texts and carries the Academy's scientific directives directly into his fieldwork along the northern Pacific coast.

In Its Own Voice

"More than fifty specimens were found on water plants in clear stagnant ponds, two or more often sticking on the back of a larger one."

This quiet observation introduces a newly discovered species of freshwater shell found in California, highlighting the meticulous, hands-on field collection that fills the volume.

"So frequent were they, that the inhabitants abandoned their houses for the greater part of this period, and lived under trees, etc., and slept out of doors at Santa Barbara."

Here, the text quotes historical accounts of the 1812 earthquake series, illustrating how human record-keeping is mined to construct the region's seismic history.

"In passing through the Italian Fish Market in this City, in the month of October, 1866, I noticed an unusually large specimen of Orthagoriscus analis, commonly called 'Sun Fish'..."

This line captures the spontaneous nature of Victorian natural science, where a routine walk through a local market becomes an opportunity for precise scientific measurement.

What It's Really About

Beneath its dry lists of specimens and meeting minutes, this volume is about the systematic organized effort to establish intellectual order on an unfamiliar frontier. In the 1860s, California was largely viewed through the lens of resource extraction—gold, copper, timber, and land. The Academy’s implicit argument is that true ownership and understanding of a region require patient, unpaid, and unglamorous empirical study.

The text constantly grapples with the tension between popular myth and scientific fact. Whether measuring the actual height of the big trees, questioning the presence of European-style glacial drift in the West, or correcting published errors regarding marine species distribution, the contributors insist on primary evidence over received wisdom.

It also reflects the collaborative nature of nineteenth-century science. Knowledge is built not by isolated geniuses in grand universities, but through a network of army officers, local teachers, miners, and amateur collectors sending boxes of rocks, pressed grasses, and bottled sea life back to a shared room in San Francisco.

Why Read It Today

This volume appeals to readers who delight in primary history, historical ecology, and the raw mechanics of scientific discovery. Reading it feels like looking through an open window into Civil War-era California. It offers a tangible sense of place, where San Francisco’s Clay Street serves as the intellectual anchor for a vast, sparsely populated territory stretching from San Diego to the Aleutian Islands.

The prose possesses a calm, unhurried clarity. Modern readers will find a quiet satisfaction in the descriptive precision—the exact dimensions of a snail shell measured in hundredths of an inch, or the vivid color changes of a sea slug dredged from Santa Barbara waters. It provides an ecological baseline showing what the Pacific West looked like before widespread urbanization altered its landscape.

The text does present real difficulties for a general reader. It is not a narrative, but an institutional ledger full of Latin binomials, chemical formulas, ore assays, and repetitive meeting notes. Structural entries often list dozens of species or mineral angles without thematic narrative. Yet for those willing to browse its pages, the reward is an authentic, unvarnished encounter with the pioneers who mapped the natural world of the American West.
