It is amazing how old questions, long since settled, continually come up for discussion. It would pay speakers to examine files of standard publications before wasting public time in giving thoughts derived from their own limited experience. We have known some favored grower of a white Doyenne pear, argue that the variety is as good as ever, in face of hundreds of examples that the fruit is valueless from a fungus attack having worn it out, - and in like manner the well-known fact that in a large number of localities the famous Albany seedling strawberry has lost the power of producing hermaphrodite flowers, and yields only staminate ones, goes for nothing at all with those in whose localities it still happens to hold its own.

It has come to be a well-known deduction, we thought, that varieties sometimes do and sometimes do not wear out. Some hold on longer than others, while some soon get unhealthy. It seems to be a law of nature that all things, sooner or later, shall wear out. Some go earlier than others. Some children die young, - some last to be centurions. Thousands of species of plants have been on the earth, as fossil botany shows, that have worn out and been replaced; though some, like the sensitive fern Onoclea sensibilis, have endured from the first till now. There is no reason to believe that varieties have any greater power than species. Some die young, some last a good while, all wear out in time.
