It is a well known fact, proved by the history of the one huge vine in the grapery at Hampton Court, in England, that a single grape-vine is much more successfully trained over a whole grape-house than the number usually grown. But there are numbers of others, as successful or more so. Manresa House at Rockhampton, also in England, according to the Journal of Horticulture, has one which occupies 3825 square feet. It is a Black Hamburg. The length of the grape-house is 224 feet. It is 26 years old. This year 625 bunches were matured, numbers weighing 3 and 4 pounds each.
