P. F. G. thinks that he has spoilt a water-colour sketch by laying in the sky unevenly, and asks if there is any remedy. Undoubtedly. Let him turn the drawing upside down, and, with a flat camel's hair brush and plenty of clean water, wet it all over; then with gentle rubbing, keeping the brush constantly full of water, level the inequalities. To remove the more stubborn blemishes, a sponge may be necessary.

Millicent seems to have had a similar trouble, which, however, is not confined to her sky; but our answer to P.F.G. applies equally to her case. We may add that by wetting an uneven wash with a soft brush and water, and rubbing it very lightly and rapidly with a cloth, the tint may be made to look even, and, at the same time, have a granulated appearance that answers well for old walls, backgrounds, portraits, and all places for which a rather rough surface is desirable. When a tint cannot be got at once of the required depth or tone, it must be gone over with other washes of colour until the object shall be attained; but in doing so, care must be taken not to disturb the under colour. When a wash of colour is laid on the paper, leave it to dry before again working on it. Any defect observed may then be rectified more easily, (2) For sketching purposes, when a very light kit is desirable, we know of nothing better than Rowney's "Registered Sketching Case," which was illustrated in their advertisement last month.
