At the Mansfield Nurseries, (Winter Brothers) are now to be seen some very fine grapes, ripe, grown in 16-inch pots, some extra large bunches among them for pot vines. Some bunches will each weigh three pounds; color and bloom perfect; foliage large and healthy. As a feat of early forcing, this surely is unparalleled. Mr. Murray Winter informs me that they cut ripe grapes all the winter, by regular successions of pot vines.' They find a ready market for all the grapes they raise, in Boston. The heavy crops they succeed in taking from the vines must make the business very remunerative. At the same nursery tomato-forcing is one of the prominent winter features; from October until May they force from forty to fifty bushels.
