Recently I have had the task of looking for texts and/or internet sites
that refer the use of canaries in coal mines for the detection of gas.
Although the phrase "like a canary in a coal mine" is very much over
used, I have yet to find a single reference in a mining text to the
actual use of canaries.
If anyone on this list is aware of any texts, bulletins, etc. that refer
to the use of canaries in coal mines, it would be very much appreciated
if you could forward this information to me. This research will be used
to provide an historical background for animals as sentinels for the
detection of environmental risks.
Thank you,
