VARIETIES OF THE GARDEN PEA. 
I regret my first communication should be of a contradictory 
character, but having satisfactorily ascertained the fact, I feel it a 
duty to set your readers right, and hope my next paper will be more 
acceptable and conciliatory.

ARTICLE VI.—ON THE PREMATURE SHRIVELING OF GRAPES 
IN FORCING-HOUSES. 
BY MR. .T. D. PARKES, F. H. S., NURSERYMAN, DARTFOUD. 
A variety of causes have been assigned for that disease in forced 
grapes, which produces a shriveled appearance in the footstalks of 
the branches, and also a want of size and colour in the berries; more 
especially in the Frontignans and muscats. Some consider that it 
proceeds from the roots being too deep in the ground; others think 
it is occasioned by the temperature of the earth, in which the root 
grows (when vines are planted outside of the house) being so much 
lower than that of the atmosphere within; and some attribute the 
disease to a want of air. 
Having observed that early forced grapes are in general free from 
this disease, and that it never occurs to grapes grown in the open air; 
and having found, in a house under my care, that some bunches 
immediately over a steam pipe were free from it; I have come to the 
conclusion that the cause is stagnation of cold moist air; and the 
remedy, the application of artificial heat, to such an extent (even in 
summer, when the weather is cloudy) as to admit, every warm day, 
of opening the windows sufficient to occasion a free circulation of 
air .—Gardener s Magazine. 
ARTICLE VIL—CLASSIFICATION AND DESCRIPTIONS OF THE 
DIFFERENT VARIETIES OF THE GARDEN PEA. 
BY MR. W. TOWNSEND, NEW CROSS. 
I promised some months ago to furnish an account of the different 
varieties of the Garden Pea (Pisum sativum) but until now no op¬ 
portunity has occurred. I hope it will not be the less acceptable on 
account of the long delay. You of course, are aware that my obser¬ 
vations have been made during several successive seasons, upon the 
same kind of soil, each variety having the same kind of treatment 
and being sown at the same time. Tt must be observed that those
