Among the many useful works of General Le Duc is the statistics of grape culture now before us, compiled by the chemist of the department, Dr. Mc-Murtrie. Fifteen hundred circulars were sent out and about half responded. Among the many interesting facts brought out by this report is the slowness with which new varieties replace the old. Concord, Catawba, Isabella and other fa- i mous old kinds are yet represented over a large extent of country. Another singular thing is the steadiness with which grapes decline in some localites. An Egg Harbor correspondent, for instance, reports that when Concord was first planted in that part of New Jersey twenty-five to thirty pounds could be taken from one vine, but this has gradually declined until two pounds per vine is about all the same vines will produce.

There is evident]}' a tale to tell about this matter, which, to an intelligent questioner, the vine would be glad to tell. To our mind improper culture is at the bottom of it all, but it will never do to tell an old " Vigneron " that he does not know what he is doing, and so the old story that "varieties wear out " goes running on.
