About the Photos

Our holdings include hundreds of glass and film negatives/transparencies that we've scanned ourselves; in addition, many other photos on this site were extracted from reference images (high-resolution tiffs) in the Library of Congress research archive. (To query the database click here.) They are adjusted, restored and reworked by your webmaster in accordance with his aesthetic sensibilities before being downsized and turned into the jpegs you see here. All of these images (including "derivative works") are protected by copyright laws of the United States and other jurisdictions and may not be sold, reproduced or otherwise used for commercial purposes without permission.

Re: Chloro Boat

Replaced by more reliable and less hazardous injection at the filter. Many of these pools were just 'ponds' lined with tiles. Drains were used for drastic changes in water level. They did not have any sort of circulation via pipes, as a typical pool does now.

The boat 'looks fun' but as anyone who has ever cleaned a shower with 5% bleach will attest, it was all but fun.

Man, what happened to these things?
We could certainly use some mega chloro boats today.
