Irving had now fairly arrived at maturity. The experience of the last few years had done much to sober him. He was still fond of society, and still of a cheerful temper; but the absorbing sophomoric joy in cakes and ale was now past and not to return. The pinch of necessity had come at last: the world no longer offered him the life of an elegant dawdler. He had a serious business before him,--to gain a competency for himself and his brother. The unpractical younger brother was to be after this the mainstay of the family fortunes. And what especially makes this the finest moment of his life is the sudden and clear perception that to gain this end he must depend upon the steady and fruitful exercise of his gift for writing. It was not to be taken up as a last resort, but as a matter of deliberate choice. Presently he received the offer of a good position on the Navy Board at Washington, with a salary of $2400. A few years earlier he would have snatched at it. "Flattering as the prospect undoubtedly is which your letters hold out," he wrote to his brother Ebenezer, "I have concluded to decline it for various reasons.... The principal one is, that I do not wish to undertake any situation that must involve me in such a routine of duties as to prevent my attending to literary pursuits." His determination was sturdy enough, but he was not then nor afterward the master of his moods. "I have heard him say," notes Pierre Irving, "that he was so disturbed by the responsibility he had taken in refusing such an offer and trusting to the uncertain chances of literary success, that for two months he could scarcely write a line." His elder brothers were heartily disappointed by the decision. They could not suppose that he would prove greatly more busy or fruitful in the future than he had in the past, and up to this time, he had done little enough. The youthful "Salmagundi" sketches, the broad satire of the Knickerbocker History were not much for a man of leisure to boast of at thirty-five. But they did not reckon justly with the new seriousness which had come into his purposes. Washington Irving was always fitful in his manner of working, often uncertain of himself and of his work. But from this time on he had no doubt of his calling; he had ceased to be a man about town, and become a man of letters. III MAN OF LETTERS--FIRST PERIOD
