We have seen no Market-Gardens of any note since writing our last. Many of the private gardens about Manchester and Liverpool send the finer vegetables, and also fruits, to market; and the vegetables sold in large quantities are raised by small farmers in the sandy districts in the neighbourhood of these towns, as at Knutsford, Altringham, Ormskirk, Everton, &c. The mode in which the Altringham carrot is cultivated for seed shall be detailed hereafter.
