1) A kind of deer-leap which involved a modification of the pale around a park. It allowed deer to enter the park but made it difficult for them to leap out again.
Mary Higham discussed the word in connection with Leagram Park within the Forest of Bowland: 1603 with a pale of wood and divers salters left therein for the deer to come out of the forest. It is said to derive from Latin saltatorium and is clearly a vernacular form. What is probably an unusual Latin spelling is found in the Ministers’ Accounts for Pickering Forest where expenses ‘for stopping up an old deer-leap’ are detailed: 1314 pro uno insultorio antiquo obstupando. An alternative English spelling is ‘sawtry’: 1526 Herry Savyll ... and his adherentes ... came to the seid park pale and satt upon the sawtryez of the seid pale, Wortley Park
1621 and so back agane on the common to the Sawtrye into Sir Henry Bellasis parke, Brandsby. The word may survive in some of the many minor place-names with ‘salter’ as an element.
