PLAIN PERPENDICULAR GRAIN.
2. [Plain white diagonal lines]. Pencil drawing.
3. [Plain white perpendicular lines]. Pencil drawing.
4. [Plain white aquatint grain]. Pencil drawing.

5. [Black aquatint]. This is not a variety in constant use. Three states are shown.
6. [Black diagonal lines]. This is the pattern in greater requisition. The method of working is shown, but the possibilities of this pattern are seen admirably and to the best advantage in the illustration of [Venetian Fête on the Seine].
