Why is Dorset's motto is 'Who is Afear'd'?

Actually the motto of Dorset is 'Who's Afear'd'

" The motto of 'Who's afear'd' was one of four originally suggested, including Lord Shaftesbury's suggestion; 'Excellence where Beauty Reigns'. 'Who's afear'd' was adopted by the Society of Dorset Men in 1905 at the suggestion of Thomas Hardy. It was converted to Dorset dialect by them in 1908, and was suggested to the County Council by a Colonel C.D.Drew, then curator of the Dorset County Museum"
