Close to it on my shelves stand four volumes which are the monument of another intellectual life devoted to the investigation of nature. De Saussure, whom Mr. Ruskin reverences as one of his ablest teachers, and whom all sincere students of nature regard as a model observer, pursued for many laborious years a kind of life which was not, and could not be, self-supporting in the pecuniary sense. Many other patient laborers, who have not the celebrity of these, work steadily in the same way, and are enabled to do so by the possession of independent fortune. I know one such who gives a whole summer to the examination of three or four acres of mountain-ground, the tangible result being comprised in a few memoranda, which, considered as literary material, might (in the hands of a skilled professional writer) just possibly be worth five pounds. Not only do narrow pecuniary means often render high intellectual enterprises absolutely impossible, but they do what is frequently even more trying to the health and character, they permit you to undertake work that would be worthy of you if you might only have time and materials for the execution of it, and then spoil it in the doing. An intellectual laborer will bear anything except that. You may take away the very table he is writing upon, if you let him have a deal board for his books and papers; you may take away all his fine editions, if you leave him common copies that are legible; you may remove his very candlestick, if you leave him a bottle-neck to stick his candle in, and he will go on working cheerfully still. But the moment you do anything to spoil the quality of the work itself, you make him irritable and miserable. "You think," says Sir Arthur Helps, "to gain a good man to manage your affairs because he happens to have a small share in your undertaking. It is a great error. You want him to do something well which you are going to tell him to do. If he has been wisely chosen, and is an able man, his pecuniary interest in the matter will be mere dust in the balance, when compared with the desire which belongs to all such men to do their work well." Yes, this is the central passion of all men of true ability, _to do their work well_; their happiness lies in that, and not in the amount of their profits, or even in their reputation. But then, on the other hand, they suffer indescribable mental misery when circumstances compel them to do their work less well than they know that, under more favorable circumstances, they would be capable of doing it. The want of money is, in the higher intellectual pursuits, the most common hindrance to thoroughness and excellence of work. De Sénancour, who, in consequence of a strange concatenation of misfortunes, was all his life struggling in shallows, suffered not from the privations themselves, but from the vague feeling that they stunted his intellectual growth; and any experienced student of human nature must be aware that De Sénancour was right.
