Thomas Ewing Dabney opens his 1921 account of the New Orleans Industrial Canal with a philosophical flourish on the frailty and power of the human mind, then pivots abruptly to the canal's engineering specifics. The book, published by the Board of Commissioners of the Port of New Orleans, is both a promotional document and a technical record. Dabney's prose oscillates between rhapsodic praise—'Man can trust his mind'—and granular descriptions of lock gates, sluice valves, and concrete viaducts. The excerpts reveal a work that treats infrastructure as heroic endeavor, with the canal's construction framed as a triumph over 'unspeakable odds.'

A Foreword's Unlikely Leap

The foreword, signed by Port Commission President William O. Hudson, begins with a meditation on the human mind's capacity to 'stand unlimited agony' and 'build against a thousand years.' This abstract, almost poetic opening seems incongruous for a canal report, yet it establishes the book's rhetorical strategy: to elevate a civil engineering project into a monument of human will. Dabney then ties this directly to the canal, claiming 'nowhere has Man won a greater triumph over unspeakable odds than in New Orleans.' The language of mental fragility—'a flower pot falling out of a window can destroy it'—is deliberately contrasted with the permanence of concrete and steel. This framing suggests the author intends the canal not merely as a commercial asset but as proof of collective intellectual daring.

Numbers as Narrative

Dabney's descriptions of the lock are dense with figures: the lock's top sits '20 feet above the natural ground surface,' the emergency dam weighs '720 tons,' and each of the five sets of gates is 'four and a half feet thick and weighing 200 tons each.' The repetition of precise measurements—'8 by 10 feet, narrowing at the opening to 8 by 8 feet'—creates a rhythm of factual authority. Yet these numbers also serve a persuasive function, implying that the canal's scale is commensurate with the city's ambitions. The inclusion of Henry Goldmark's letter, praising the 'uniformly high grade of construction' and 'unique method used for carrying on the very difficult and risky work of excavation,' adds an external voice of expertise. Dabney lets the engineer's technical approval stand as objective validation.

Buried Forests and Subterranean Rivers

In a striking phrase, Dabney mentions 'the dredging of a canal through buried forests 18,000 years old, the creation of an underground river.' This geological detail is not elaborated in the excerpts, but it hints at the physical challenges faced during excavation. The 'buried forests' evoke a prehistoric landscape beneath the modern city, while the 'underground river' suggests the need to manage groundwater or redirect subsurface flows. Such references ground the canal's construction in a deep time that contrasts with the rapid pace of industrial expansion. Dabney's willingness to include these natural obstacles underscores the narrative of human ingenuity overcoming not just financial or political hurdles, but the very forces of geology.

The Lock as a Machine for Commerce

Dabney devotes considerable attention to the lock's operational details: six capstans 'each operated by a 52-horsepower electric motor,' sluice gates closed by motors of the same power, and a filling or emptying time of ten minutes. The lock is presented as a finely tuned mechanism, with 'the refinement of precaution' embodied in the emergency dam. The description of traffic crossing via a 'steel bascule bridge 65 feet wide, with two railroad and two street car tracks, two vehicle roadways, and two ways for pedestrians' emphasizes the integration of the canal into the city's transport network. Dabney's focus on these functional elements suggests that the canal's value lies not just in its existence but in its efficiency and redundancy—a system designed to keep commerce moving even in the event of a gate failure.

Dabney's book is best read as a hybrid: part civic boosterism, part engineering case study. Readers interested in the rhetoric of infrastructure will find his juxtaposition of philosophical preamble and technical specification revealing. Those seeking pure data will appreciate the detailed lock dimensions and cost breakdowns. The excerpts do not cover the canal's economic impact or later history, so the book's claims should be weighed against other sources. Approach it as a contemporary document that reveals how early twentieth-century New Orleans chose to narrate its own industrial ambition.
