plant is six feet, its diameter ten and a half feet, and its age 
four years. We have two more, nearly as good ; and two others 
one year old, which have opened 100 flowers each. In the 
morning and evening, the fragrance of these flowers scented the 
air to the distance of 60 yards. An engraving of the Brugman-

The principle here acted upon by Mr. Spence, that of short- 
ening the roots to induce the production of laterals, or additional 
feeders, and then increasing their supply of nutritive matter, is 
one that deserves the attention of all Horticulturists. This 
principle may be applied by numerous methods, which will 
readily present themselves to the minds of practical men. Judg- 
ing of the principle, theoretically, (for we have not practical 
knowledge on the subject) we may as reasonably anticipate 
advantages to accrue, in many instances, from pruning the roots 
of a plant, as from shortening its branches. 
133 Filberts; Planting. So little attention is usually paid to 
the management of Filbert Bushes, that we think an article on 
the subject in the Auctakium may be useful to very many of 
our readers. More plain and practical directions we have not 
met with, than are given by Mr. Rogers in his Fruit Cultivator, 
a little work of real merit, — a practical guide ; to which we are 
indebted for the following instructions. The cultivation of the 
Filbert in England is but little regarded, excepting in the 
county of Kent, where hundreds of acres testify that it forms a 
prominent branch of rural economy. The most favourable 
land for a plantation seems to be a light loam on a dry gravelly 
subsoil ; with proper attention, however, the Filbert will succeed 
on almost any soil or situation. It should be observed that too 
rich a soil is not favourable to its productiveness ; hence it is 
not requisite that manure be supplied to the ground in which 
it is planted. Winter, or very early in spring, is the season for 
making plantations. “ The young plants which are chosen by 
the Maidstone growers are such as have been raised from layers, 
and which have been lined or bedded out in the nursery for two 
or three years. The plantations in Kent are either in single 
rows, or in entire quarters or fields. The plants are put in at 
eight or ten feet distances, more or less, according to the quality 
of the soil. Six hundred and eighty plants are required for an 
acre, at eight feet distances every way ; at ten feet distances,
