We left Chatsworth with regret; the day we spent there we would have gladly prolonged to a week, and then we should have gained but an imperfect knowledge of the treasures of nature and art which are stored up here for the admiration of thousands of visiters. Mary Queen of Scots was some time a prisoner here; so also was Marshal Tallard, who was captured at the battle of Blenheim. What were the thoughts of the beautiful Queen upon taking leave of it, history does not record; but the Marshal, no less gracefully than happily, said: "When I return to France and reckon up the days of my captivity in England, I shall leave out all those I have spent at Chatsworth." And so thought we, pausing on the mound-like hill again, as we retraced our steps to Edensor, and cast a last lingering look upon the park, and palace, and forest hills in the background, lit up by the clear, glorious sun just sinking beneath the horizon. AGRICULTURAL SHOWS. THE PHILADELPHIA SOCIETY held its annual show at the Lamb tavern, October 4, 5, and 6. The Germantown Telegraph states, in the _Report of the Committee of Arrangements_, that the display of horses was unusually attractive, exhibiting the various breeds for the turf, road, and farm, in considerable numbers. The Durham cattle seem at last to be getting the better of prejudice in that quarter, and in their superior forms and deep milking qualities, have shamed nearly everything else from the ground, save a few fine Devons and capital grade Durham milkers. Of sheep and swine, there were very few present, which is the more to be regretted, as these animals exist in considerable numbers and of superior breeds throughout the neighboring counties of Montgomery, Delaware, Chester, and Lancaster. Of Agricultural Implements and Products there was a good show, and the Plowing-Match proved an interesting affair. Peter A. Browne, Esq., delivered the address, which we find at length in the Farmers' Cabinet. Among other things, he contends no less strenuously than justly for the establishment of Agricultural schools and Professorships. From another part of the address we subjoin a few suggestions. First, then, it is feared that our agricultural friends have not yet paid _all_ the attention that the subject demands, to a judicious rotation of crops, adapted to our climate; particularly in regard to _roots_. Second. Much has been done, that is beyond all praise, in insuring the best breeds of cattle. While we hear pronounced with gratitude, the names of Mease, Powell, Brantz, Clay, Gowen, and Kelley, let us not forget that the task is not finished. Third. Soiling, it is apprehended, has been too much neglected by most American husbandmen. Fourth. Irrigation has also been too little attended to in the United States. Fifth. Proper care and precaution have not been sufficiently bestowed upon the selection of seeds. This is a subject of the greatest importance.
