Thwartled and a mystery cross

What is the meaning of the old Sussex word ‘thwartled’?

Here is a clue. The Marchant Diary contains the following entry: “George and May thwartled; the boys rolled in the afternoon.” Thwartled means cross-ploughed.

*In 1932 one E Kemp of Ninfield wrote the following to the Sussex County Magazine: “Some years ago I made a pilgrimage to Lewes on purpose to find the Bethesda Chapel.

“As I was going John Street, a woman was standing at her door so I asked her where the Chapel was.

“ ‘Yes sir, right opposite,” she said. “I asked what had become of it?”

“ ‘It fell down one snowy night,’’ she replied. “Now it is a girls’ school and a builder’s warehouse.’’ ‘

* Another letter to the SCM: “On a recent Downs walk near Ditchling Beacon I came across a small iron cross about 3ft high in a direct line with Westmeston Church, almost on the top of the Down.

“The left arm of the cross bore the date October 8; in the centre were three initials CHC and on the right the date 1888. Is the reason for its erection known?”
