Henry P. Bowie, On the Laws of Japanese Painting…
“ The brush, when dipped first into the water, may absorb too much or not enough, and the sumi or ink taken on the brush may blot or refuse to spread or flow upon the material, or it may spread in the wrong direction. The Chinese paper (toshi) which is employed in ordinary art work may be so affected by the atmosphere as to refuse to respond, and the brush stroke must be regulated accordingly. All such matters have to [pg 34] be considered when the brush is being used, and if the spirit of the artist be not alert, the result is failure. ”
