GOSSIP WITH READERS AND CORRESPONDENTS.--We would respectfully ask the reader's attention to the advertisement of the '_Knickerbocker Library_,' on the second page of the cover of the present number. 'Our best exertions shall not be wanting' to make the series all that the publishers hope for it. That the _materiel_ is good, our readers, we think, need not be informed. The plan has been cordially welcomed by the press, with a single exception; and in that, the _quo animo_ was so apparent as to neutralize the slur intended by the writer. We shall be enabled to secure the earliest literary rarities on both sides of the water for the 'Knickerbocker Library,' and the style in which they will be presented will be unsurpassed. . . . WE lament in the recent death of WILLIS GAYLORD, the loss of a beloved relative, who was our elder companion in childhood and youth, and our faithful friend and correspondent, to the close of his useful and honored life.

In the pathetic language of one by whom the intelligence of his death is communicated, he was truly 'the friend of the farmer--the friend of humanity.' We have the proceedings of a meeting of the New-York Agricultural Society, held in the State-House at Albany, on receiving the intelligence of the death of Mr. GAYLORD. The President, JOHN P. BEEKMAN, Esq., of Columbia county, passed a high and deserved eulogium upon the character of the deceased. 'The judgment of every intelligent farmer in the State,' he observed, 'will respond to the assertion that to no man whatever, excepting perhaps Judge BUEL, is the agriculture of the State more indebted than to Mr. GAYLORD. For myself, I can declare in all sincerity that there is no man whose writings caused within me a greater desire to be honored with a personal acquaintance. The character of WILLIS GAYLORD was in all respects what might be expected from his writings; benevolent, enlightened, elevated; yet plain, practical, unassuming. Every day of his useful life was marked, not merely by the exercise of his versatile talents on the multifarious subjects embraced by agriculture and the domestic arts, but by the acquisition and promulgation of knowledge in
