In 1842, Irving suffered another of those petty persecutions which he was not thick-skinned enough to endure without suffering, nor confident enough to ignore. The charges were of the most ordinary sort, and advanced by men of little weight: he had appropriated material without giving due credit for it, and he had puffed his own work. Their only claim upon our notice lies in the fact that Irving thought it worth while to confute them at length. He was perhaps especially sensitive to critical attacks at this time. His income from literary property had nearly ceased. Some of his books were out of print, and the rest were having comparatively little sale. A wave of indifference had overtaken his public. "Everything behind me seems to have turned to chaff and stubble," he wrote. "And if I desire any further profits from literature, it must be by the further exercise of my pen." It is characteristic of his modesty that he was disposed to accept this momentary neglect as final. He planned to revise all his works, in the hope of finding a renewed market for them later, but evidently expected little. A letter to Brevoort from Bordeaux dated November, 1843, accounts for the first break in his Madrid residence: "I am now on my way back to my post, after between two and three months' absence. I set out in pursuit of health, and thought a little traveling and a change of air would 'make me my own man again'; but I was laid by the heels at Paris by a recurrence of my malady, and have just escaped out of the doctor's hands.... This indisposition has been a sad check upon all my plans. I had hoped, by zealous employment of all the leisure afforded me at Madrid, to accomplish one or two literary tasks which I have in hand.... A year, however, has now been lost to me, and a precious year, at my time of life. The 'Life of Washington,' and indeed all my literary tasks, have remained suspended; and my pen has remained idle, excepting now and then in writing a dispatch to Government, or scrawling a letter to my family. In the mean time the income which I used to derive from farming out my writings has died away, and my moneyed investments yield scarce any interest.... However, thank God, my health and with it my capacity for work are returning. I shall soon again have pen in hand, and hope to get two or three good years of literary labor out of myself."
