[The following experiments with Potatoes were conducted under the direction of Admiral Horby, and are very interesting to Potato-growers. - Ed].

We give below the results of experiments with fourteen varieties of seed Potatoes. All the varieties were treated alike, and sown in black soil on the Knowsley Cottage Farm. Nos. 1, 2, 3, 5, 6, 8, 9, 13, and 14, were obtained from Scotland. All these are good eating Potatoes, the first particularly so; and of this kind beautifully shaped single Potatoes have been turned up from 28 to 31 oz. in weight.
