Having lost his parents, his father in 1800 and his mother in 1805, Crosse took over the management of the family estates at the age of 21. Among his experiments Crosse erected "an extensive apparatus for examining the electricity of the atmosphere," incorporating at one point an insulated wire some long, later shortened to , suspended from poles and trees. Using this wire he was able to determine the polarity of the atmosphere under various weather conditions. His results were published by his friend George Singer in 1814, as part of Singer's "Elements of Electricity and Electro-Chemistry".
