There is always considerable uncertainty hanging over the fate of these stocks. Sometimes they will pass through a winter unscathed, and at another time will be destroyed wholesale. My experience of them has hitherto been of a very unsatisfactory kind, having on several occasions lost the whole of what otherwise appeared to be a most promising lot of plants. I hope, however, that I have just gained a wrinkle that will, in the future, prove useful. I planted out in the open ground early in the summer two separate beds of the hybrid striped Brompton Stock, which had, by the commencement of the winter, grown into very strong plants. Finding it then necessary to transplant one of the beds, I did so, and placed them close to the others, so that they formed one entire bed of about 200 plants. What is now their relative appearance? Why, this: that the severe frost we had at the end of the year killed 80 per cent of the original bed, whilst those transplanted are comparatively unhurt. After this experience I shall always transplant my winter Stocks.
