No man ought to buy a name and grumble afterwards if the picture becomes of less value. Even such names as Raphael ought to weigh as nothing when before their pictures. If the thing is bad in Raphael, it is bad in Whistler; if it is good in Raphael, it could not be bad if it was Whistler. If a picture is worth 200_l._ to the man who paid that sum for it, it can never be worth a farthing less to him afterwards. If a man buy a coat, a house, a horse, or a picture, he ought to know _why_ he is buying it; and if it is value in his eyes, it cannot, or ought not to, be made valueless by all the newspapers or critics in the world. And if he has no knowledge on the matter, no likings, no opinions, he ought to depend on some one whom he can trust who has knowledge, and never alter afterwards; or he ought to spend his money only on what he has fixed ideas about, or give it away in the cause of charity, about which we all, as human beings, even the weakest, have surely some sentiment clinging about us as a forecast of heaven. If he spends his money only for fashion's sake, he deserves not only to lose it, but to lose also the respect of every man of sense and purpose, for he is a fool incurable. We cannot all be educated on every subject, but we can all tell what pleases us, and it is our duty to manhood to say so, and not take the opinion of others against our feelings. For instance, if we are eating something nice, is it no longer nice if our neighbour says it is not? or ought we weakly to take the fashionable dish that we abhor, and pay ever so much more for it, with our mouth watering after the cheap dish that we can understand and relish? Water-colour painting is the use of transparent colours with the ground or paper serving as our white. The treatment may either be by wash or stippling and hatching. Stippling and hatching is the going over our work with dots or crossed lines. Like engraving, its chief merit is the vast labour it costs, if that is a merit; yet at times it has to be done where washes fail to bring the effect. Opaque or body colour, like fresco painting, is the mixing of Chinese or zinc white with the colours. A little chemistry should be studied in this work, as some of the other metals do not agree with zinc.
