Story of buying mill in 40 acres of land. Comments on importance of remoteness of laboratory for measurements; reasons for moving from Bowerchalke. [34:22] Comments on need to calibrate commercial ECDs. Story of using old barn space to calibrate ECD using ‘exponential dilution’ technique. Detailed description of calibration process. [39:33] Discussion of use of calibration measurements in global ‘Atmospheric Lifetime Experiment’ [ALE]. Story of establishing ALE, for CMA. Comments on location/personnel of ALE stations. Mentions later take-over of ALE by GAGE. [42:04] Mentions ill health of self and wife; transfer of Adrigole station to Mace Head, Galway by GAGE. [43:12] Discussion of consistency across ALE network. [44:20] Story of buying holiday cottage on Bantry Bay, Adrigole in mid 1960s. Description of rural poverty in Western Ireland, mid 1960s.
