Note 133 — NOTES ON PARISHES ROUND HORNCASTLE. (continued 4)
Reading edition
Our modern rock-salt was unknown till 1670, when it was accidentally found in Cheshire. Before that time the only salt in use, was that collected by evaporation, in “salt-pans,” on the Humber or the sea-coast. Of these, Sharon Turner calculates (“Hist. Anglo-Saxons,” vol. iii., p. 251, Ed., 1836), that there were no less than 361 in the county.
