fecundation: if so, the shells of the fruit of any walnut tree may be 
rendered tender, by removing all, or the greater part, of the male 
catkins, the moment they appear.

vegetating Walnut. — This is a most valuable variety for those dis- 
tricts where the frosts continue late in spring. In France, about 
Paris, its leaves do not appear before the end of June; but the fruit 
ripens nearly as early as that of the other varieties. In the London 
Horticultural Society’s Garden, there is a plant of this variety, 5ft. 
or 6ft. high, which, on the Ist of July, 1835, when every other tree in 
the garden was in leaf, had not burst a single bud.

Other Varieties. The above are the most remarkable and valuable of the 
varieties of the common walnut; the first three, on account of their fruit ; 
and the last, as a curiosity, on account of its leaves, But in the Bon Jardinier 
five others are enumerated; and in the Horticultural Society’s Fruit Cata- 
logue for 1832 nine are given, of which the most valuable for cultivation for its 
fruit is the highflier ; a variety which was originated at Thetford, in Norfolk, 
and which is held in much esteem in that county and in Suffolk. (Hort. . 
Trans., iv. p. 517.; and E. of Gard., ed. 1835, p. 942.) There is also the 
Yorkshire walnut, which is much planted in that county. The varieties 
recommended by Mr. Thompson, as having proved the most prolific in the 
Horticultural Society’s Garden, are, the round early oval; the double large 
French, No. 1, above; the tender-shelled, No. 2.; and the thick-shelled. 
A variation, worth notice, was displayed in a nut sent to us by Mr. 
Samuel Taylor of Whittington, near Stoke Ferry, Norfolk, which had 
nearly three perfect valves, but was devoid of kernel. 
Description. The walnut forms a large and lofty tree, with strong spread-/ 
ing branches. The leaves have three or four pairs of leaflets, terminated by an 
odd one, which is longer than the rest. The male catkins are pendulous, and 
are produced near the points of the shoots. The bark is thick, and deeply 
furrowed on the trunk; but on the upper branches it is grey and smooth. 
The leaves, when bruised, exhale a strong aromatic odour; and, in the ex- 
treme heat of summer, the exhalations from them are so powerful, as to 
produce unpleasant effects upon some persons, if they slumber under the
