The Duke of Buccleuch Grape does well on its own roots; but our own experience is that the Muscat of Alexandria is the stock for both it and the Golden Champion. It does not follow that because a Vine is very strong growing that it makes a good stock for others. Gros Guillaume, a very strong grower, is the worst of stocks, and it does best itself in Muscat roots. We have proved this beyond a doubt. Black Hamburg, an excellent stock for some Grapes, is not the stock for Gros Guillaume. It does very well on Hamburg roots for about two years, and then goes back; others have proved this besides ourselves.
