Report to Hon. A. V. Brown, Postmaster-General : on the opening and present condition of the United States overland mail route between San Antonio, Texas, and San Diego, California

A diligent superintendent has been tasked with documenting the fledgling overland mail line that stretches from the rugged hills of San Antonio to the sun‑baked coast of San Diego. In a formal report addressed to the Postmaster‑General, he blends official statistics with vivid notes from his own journey, sketching the soil, climate, deserts, mountains and the sparse water sources that punctuate the route. His tone is practical yet curious, offering a clear picture of a corridor still being tamed by engineers and traders.

Interwoven with the technical data are excerpts from his travel journal, revealing the frantic scramble to assemble outfits, purchase supplies and secure mules before the first scheduled departure. He recounts the urgency of coordinating with distant partners, the surprise of missing dates and the difficulty of finding suitable animals in a frontier town. Listeners get a front‑row seat to the logistical puzzles and raw determination that shaped America’s early long‑distance communications.
