An engraver whose hands must be of an exquisite delicacy of stroke, should not lay stone walls. Sir David Brewster gives exact instructions for microscopic observation:—"Lie down on your back, and hold the single lens and object over your eye," &c. &c. How much more the seeker of abstract truth, who needs periods of isolation, and rapt concentration, and almost a going out of the body to think! 2. Spend after your genius, _and by system_. Nature goes by rule, not by sallies and saltations. There must be system in the economies. Saving and unexpensiveness will not keep the most pathetic family from ruin, nor will bigger incomes make free spending safe. The secret of success lies never in the amount of money, but in the relation of income to outgo; as if, after expense has been fixed at a certain point, then new and steady rills of income, though never so small, being added, wealth begins. But in ordinary, as means increase, spending increases faster, so that, large incomes, in England and elsewhere, are found not to help matters;—the eating quality of debt does not relax its voracity. When the cholera is in the potato, what is the use of planting larger crops? In England, the richest country in the universe, I was assured by shrewd observers, that great lords and ladies had no more guineas to give away than other people; that liberality with money is as rare, and as immediately famous a virtue as it is here. Want is a growing giant whom the coat of Have was never large enough to cover. I remember in Warwickshire, to have been shown a fair manor, still in the same name as in Shakspeare’s time. The rent-roll, I was told, is some fourteen thousand pounds a year: but, when the second son of the late proprietor was born, the father was perplexed how to provide for him. The eldest son must inherit the manor; what to do with this supernumerary? He was advised to breed him for the Church, and to settle him in the rectorship, which was in the gift of the family; which was done. It is a general rule in that country, that bigger incomes do not help anybody. It is commonly observed, that a sudden wealth, like a prize drawn in a lottery, or a large bequest to a poor family, does not permanently enrich. They have served no apprenticeship to wealth, and, with the rapid wealth, come rapid claims: which they do not know how to deny, and the treasure is quickly dissipated.
