This primitive and historical mansion has since passed through many changes and trials, which it may be my lot hereafter to notice. At the time of the sojourn of Diedrich Knickerbocker it was in possession of the gallant family of the Van Tassels, who have figured so conspicuously in his writings. What appears to have given it peculiar value, in his eyes, was the rich treasury of historical facts here secretly hoarded up, like buried gold; for it is said that Wolfert Acker, when he retreated from New Amsterdam, carried off with him many of the records and journals of the province, pertaining to the Dutch dynasty; swearing that they should never fall into the hands of the English. These, like the lost books of Livy, had baffled the research of former historians; but these did I find the indefatigable Diedrich diligently deciphering. He was already a sage in year's and experience, I but an idle stripling; yet he did not despise my youth and ignorance, but took me kindly by the hand, and led me gently into those paths of local and traditional lore which he was so fond of exploring. I sat with him in his little chamber at the Roost, and watched the antiquarian patience and perseverance with which he deciphered those venerable Dutch documents, worse than Herculanean manuscripts. I sat with him by the spring, at the foot of the green bank, and listened to his heroic tales about the worthies of the olden time, the paladins of New Amsterdam. I accompanied him in his legendary researches about Tarrytown and Sing-Sing, and explored with him the spell-bound recesses of Sleepy Hollow. I was present at many of his conferences with the good old Dutch burghers and their wives, from whom he derived many of those marvelous facts not laid down in books or records, and which give such superior value and authenticity to his history, over all others that have been written concerning the New Netherlands. But let me check my proneness to dilate upon this favorite theme; I may recur to it hereafter. Suffice it to say, the intimacy thus formed, continued for a considerable time; and in company with the worthy Diedrich, I visited many of the places celebrated by his pen. The currents of our lives at length diverged. He remained at home to complete his mighty work, while a vagrant fancy led me to wander about the world. Many, many years elapsed, before I returned to the parent soil. In the interim, the venerable historian of the New Netherlands had been gathered to his fathers, but his name had risen to renown. His native city, that city in which he so much delighted, had decreed all manner of costly honors to his memory. I found his effigy imprinted upon new-year cakes, and devoured with eager relish by holiday urchins; a great oyster-house bore the name of "Knickerbocker Hall;" and I narrowly escaped the pleasure of being run over by a Knickerbocker omnibus!
