It will be advantageous to cover the Vine-border, so as to keep the roots dry. This can be done with tiffany or wooden shutters; the last named is the best thing, as they can be made cheaply, and will last several seasons. Actually, the cost would not be much larger than for frigi-domo. The latter rots quickly, while the shutters are durable. The covering should be put on the Vine-border at the beginning of October.
Never mind what you read to the contrary. Next year, when your Lady Downes Grapes are stoning, keep the house as cool as a greenhouse for three weeks, and "the spot" will do you no serious damage. This is our experience, and we have grown that best keeper of all Grapes for fourteen years.
The difference between what you term the "two supposed varieties " is an assumed one; there is no difference. Its origin is at present involved in mystery. Though claimed to be a seedling of recent date, it has been found in somewhat obscure districts, where it has been for several years past. Later in the season it will come very fine indeed.
This is quite distinct from the Viola Blue Perfection as sent out by Mr B. S. Williams. It is pretty, and free-blooming, and likely to be useful in the flower garden. We think it a pity it was so named, as it leads to confusion.
October is the proper time to put in Calceolaria cuttings, and of the recently made wood. They may be kept as you describe, and should be transplanted and hardened off before final planting in the open ground. We know of nothing to take the place of Viola cornuta in your case. Sow at once and encourage the growth, and it will suit you.
We never raised Cerastium tomentosum from seed, but believe it will be in plenty of time if sown now as you propose.
There are a great many yellow Violas both in flower and growth that are not easily distinguished. The following three are distinct and most profuse bloomers, and are sure to give satisfaction, viz., Golden Perpetual, Lutea Major, and Lutea de Massipp.
The dropping of leaves is very common this year. Green-fly early in the season and the cold wet summer have caused it.
