Arlington

 The Sanborn dated 1911 (Sheet 5) depicts a small one-story wood jail in Arlington, Texas. It was located in block 49 bordered by Center and Abrahms streets.  It was gone In 1917 (Sheet 2) and there was a much smaller one-story wood jail in block 47 or 48 next to the Fire Department.

Fort Worth

The Sanborn fire insurance maps dated 1885, 1889, and 1893 (all Sheet 3) depict a small one-story brick building in Fort Worth, Texas. It was located next to the two-story brick county jail just to the north of the Public Square. The map refers to it as “old” and this suggests to me a vacant calaboose that was used prior to the completion of the county jail.  The only jail present in 1898 (Sheet 1) was a three-story structure described as fireproof.
