On the 6th we left Harrisburg, at 9 o'clock in the morning, for New York, visiting the famous Iron Works on our way, and halting at Middleton to inspect the farm of Colonel Long, which is one of the sights of the country, and which all the agriculturalists of the party declared was an exceedingly well-managed display of agricultural skill; an admirable exhibition of what may be done in the States to emulate the best establishments of the old country. The produce of the farm was pronounced to be excellent, the fields clean and well apportioned, beautiful pasture for stock, and fine arable for various crops, but the result of conversation with Colonel Long led some of the party to the conclusion that a farmer with good land in England can, at present prices, hold his own with any farmer in the Eastern States. The most interesting fact connected with the investigation was the discovery that the cultivation of tobacco is making great way in Pennsylvania, and that wheat has been abundant in consequence of the impossibility of competing with the West. Heavy manuring is requisite; nevertheless large tracts of Pennsylvania are passing under cultivation for tobacco-growing, and are stated to produce a weed almost equal to the best Maryland or Virginia.
