In a letter before us the writer says he has tried twelve of the grapes " everywhere recommended as the best," and after half a dozen years of trial, does not regard any but the Concord to be worth growing in New Jersey. Then at the recent meeting of the Pennsylvania Society at Bethlehem, Mr. Thos. K. Harvey stated that he had tried, a very large number, and would discard all but Concord and Clinton. We have not got down to this yet. We see everywhere about us people who raise other varieties to great perfection, and we are ready to believe that the failures are due to causes which can be remedied.
