• "The conception is dignified, the expression resolute, yet tempered by that look of abstract thought which the painter reads into the faces of his sitters."
• "I am glad you like my school-boy's verses; I think them remarkably good, because of their simplicity and singleness of purpose, the absence of all matter foreign to the theme, such as abstract thought or generalizing sentiment or feeling, the concrete quality, in short, which is an important element in all really good poetry, and very rare in that written at an early age."
