John S. Trecartin

John S. Trecartin is known for Raising P. V. Squabs for Profit, a hands-on manual drawn from his own experience building and running the Passaic Valley Squab Farm in Caldwell, New Jersey. In the book, he presents squab raising not as a hobby, but as a serious commercial venture, with advice on housing, feeding, breeding, and marketing.

The surviving record available online is fairly slim, but the book itself makes clear that he wrote from practical knowledge and aimed to help readers build a workable business. That direct, experience-based approach gives his writing a useful, plainspoken feel that still appeals to readers interested in small-scale farming and older agricultural methods.

Because reliable biographical sources on him are limited, much of what can be said with confidence comes from the book and library records rather than from detailed modern profiles. Even so, his work remains a vivid snapshot of an era when specialized farm manuals were written by people actively doing the job themselves.
