Alexander Hastie Millar, Dictionary of National Biography… (1912)
“ He found English subjects for his pictures in Surrey, Kent, and Yorkshire, but his main themes were Scottish highland landscapes. He was a pioneer among the Scottish 'out-of-door' artists, frequently completing his pictures directly from nature a practice which explains his vigour and realism. In 1871 he was elected an associate of the Royal Scottish Academy, and in 1884 an academician. His diploma picture, dated 1883, is a characteristic highland landscape, 'Coire-na-Faireamh,' now in the Scottish National Gallery, Edinburgh. ”
