Few people have an idea of the vast strides which have been made in the skilful culture of the hothouse grape. The Florist and Pomologist, has recently placed on record the full notes made at the National Show of 1881, at Manchester, in England. The premiums for the heaviest bunch of grapes was awarded to Mr. Roberts, gardener to the Countess of Charleville. It was the variety GrosGuillaume, and weighed twenty pounds! He also exhibited one bunch of Trebbiana, a white grape, which weighed twenty pounds, three ounces. The premiums ranged from $100 to $150.
