The Repair of Casa Grande Ruin, Arizona, in 1891: Fifteenth Annual Report of the Bureau of Ethnology to the Secretary of the Smithsonian Institution, 1893-94, Government Printing Office, Washington, 1897, pages 315-348

In Short

This report details the Bureau of Ethnology’s 1891 intervention to save the Casa Grande ruin in Arizona from imminent collapse. Through technical specifications, administrative correspondence, and site surveys, the document chronicles the precarious state of the structure—a massive, rammed-earth dwelling—and the emergency repairs performed to hold its walls together. Beyond a mere project summary, the work serves as an early, sobering argument for the federal responsibility to protect irreplaceable indigenous heritage from the dual threats of natural weathering and human vandalism.

The Story

The narrative begins with a recognition of the Casa Grande ruin as a unique, singular survivor among the prehistoric clusters of the Gila and Salt River valleys. Unlike many other sites that have vanished into the landscape, this specific structure remains standing, though it is rapidly succumbing to the ravages of time. The author establishes that while natural erosion has been a slow, consistent force for centuries, the damage inflicted by souvenir-seeking tourists over the previous two decades has been significantly more destructive. The walls, composed of massive, hand-laid blocks of rammed earth, have begun to sap at the ground level, creating a structural weakness that threatens to bring the entire building down.

The government’s response is born of bureaucratic necessity. After initial, impractical proposals by special agents are discarded, the Bureau of Ethnology assumes control. The work is defined by limited resources and the need for immediate, targeted intervention. A contract is awarded to local builders, prioritizing four critical actions: clearing debris, underpinning the eroding walls with brick, repairing missing lintels in the doorways, and installing braces to prevent the south wall from bowing outward. The project is a race against a two-month, later extended to four-month, deadline.

As the work progresses, it becomes clear that the budget is insufficient to cover all desired repairs, leading to the omission of a proposed roof—a decision that haunts the later sections of the text. By the time the contractors finish, they have significantly exceeded their original estimates for material and excavation, performing a level of labor that earns praise for quality but leaves the project technically incomplete.

The final arc of the report shifts from the 1891 repair to a retrospective analysis conducted in 1895. The site’s custodian, Reverend Isaac T. Whittemore, begins an urgent correspondence with federal authorities, arguing that the emergency work of 1891 was merely a stopgap. A subsequent inspection by W. J. McGee confirms this fear: while the reinforced portions remain stable, the profiles of the walls are being slowly lowered by wind and rain, and new crevices are widening. The report concludes with an authoritative recommendation for the installation of a permanent roof to shield the site, framing the ruin not just as a pile of earth, but as a critical, tangible record of a prehistoric people that the government is obligated to preserve.

How It Unfolds

The site's significance The author provides an architectural analysis of the ruin, noting that it is unique for its height and its construction technique of rammed-earth blocks. He emphasizes its strategic location on a flat plain, which once offered an unparalleled view of the surrounding Gila valley.

The call to action Initial attempts by government agents to secure the site prove too costly or impractical for the allotted budget. The Bureau of Ethnology is brought in to streamline the project, focusing on emergency measures that can be executed quickly and within a strict financial limit.

The mechanics of restoration The reader is walked through the specific, physical challenges of the repair, including the need to excavate base-level debris and the delicate process of underpinning walls with brick. Each phase is documented with legal contracts, oaths of disinterestedness, and detailed specifications for materials like squared lumber and cement mortar.

The assessment of labor A formal report provides a side-by-side comparison of the work authorized versus the work actually performed by the contractors. While the builders exceeded their contract in volume, the author notes that the site remains vulnerable without further intervention.

The plea for longevity The closing sections move to 1895, where the failure of the initial, smaller-scale repairs becomes evident. The report concludes with official recommendations to Congress to secure long-term protection for the site, shifting the focus from repair to permanent stewardship.

The People

Cosmos Mindeleff acts as the primary voice, serving as the technical architect and the administrative face of the Bureau of Ethnology. He is a pragmatic, precise observer who balances the reality of limited government funding against the undeniable, crumbling needs of the site. His writing is marked by a clinical dedication to documentation, viewing the ruin as a vital historical record that requires scientific management.

Reverend Isaac T. Whittemore, the site’s custodian, appears in the later portions of the book as the moral and practical advocate for the ruin. He represents the local perspective, possessing an intimate, daily knowledge of the site’s deterioration that he translates into fervent appeals to the Secretary of the Interior. His persistent requests for more funding demonstrate a shift from simple maintenance to a more protective, curator-like mindset.

The contractors, T. L. Stouffer and F. E. White, appear as the hands-on agents of the work. Despite the financial constraints and the potential for corner-cutting, they are credited with doing high-quality work, even exceeding their authorized workload to ensure the integrity of the underpinning. They represent the practical, local partnership required to translate federal policy into physical reality in the rugged, remote environment of 1890s Arizona.

In Its Own Voice

"Casa Grande ruin occupies a position near the southwestern corner of the group, and its size is insignificant as compared with the entire cluster of ruins, or even with the remains of the large structure which occupied the north-central part of the area."

The author establishes the physical context of the site, clarifying that the famous ruin is only a small portion of a much larger, neglected archaeological expanse.

"When abandoned, however, sapping at the ground level would commence and would in time bring down all the walls; yet in the two centuries which have elapsed since Padre Kino's visit to this place--and Casa Grande was then a ruin--there has been but little destruction from the elements, the damage done by relic hunters during the last twenty years being, in fact, much greater than that due to all causes in the preceding two centuries."

This observation highlights the sudden, alarming shift in the preservation status of the ruin caused by the influx of human visitors.

What It's Really About

The book is centrally concerned with the tension between the physical fragility of the past and the slow, bureaucratic machinery of the state. It raises the question of whether a ruin can truly be "preserved" through temporary measures, or if preservation requires an ongoing, escalating commitment of resources. The text implicitly argues that historical sites are not static objects but living concerns; once the initial intervention is made, the government assumes a permanent role as a guardian. It also subtly critiques the romanticism often applied to archaeological sites, insisting instead on the importance of accurate measurements, technical specifications, and historical context to ensure that the preservation process itself does not destroy the authenticity of the site.

Why Read It Today

Readers with an interest in the history of the American West or the evolution of historic preservation will find this report fascinating. It captures a pivotal moment when the United States began to formally recognize that certain landscapes were not merely resources to be exploited, but heritage to be protected. The prose is clean, direct, and unapologetically technical, reflecting the mindset of a late-19th-century scientist tasked with saving a piece of history before it dissolves into the desert floor.

While the book contains the detached, sometimes clinical tone of a government report, it is imbued with a quiet urgency that remains relevant. Modern readers may find the period-specific attitudes towards indigenous history, filtered through the lens of colonial-era explorers like Padre Kino, to be a stark reminder of the era’s limitations. However, there is a profound, almost poignant satisfaction in following the meticulous effort to save a structure that has outlasted its original builders by centuries. The photographs and detailed descriptions of the repair process allow you to visualize the ruin in its raw, vulnerable state, making the reader feel like a witness to a historic act of salvage. If you enjoy the intersection of engineering, history, and the quiet beauty of the desert, this report offers a rewarding, grounded experience.
