states, that the old and new seed being sown in equal parts, a quart 
for an acre broad cast, the latter attracts the fly till the whole is 
strong enough to escape. 
3. To Destroy Insects on Fruit Trees. —Two gallons of 
boiling water poured on two ounces of tobacco, and three or four 
handfuls of the tender shoots of elder. The trees sprinkled with a 
small hearth-brush for two or three weeks, will effectually destroy 
the insects. Elder-water frequently sprinkled on honey'-suckles and 
roses, prevents the insects lodging upon them. The above decoction 
may be made of any strength, as it is perfectly innocent to the tree. 
See Vol. 3. p. 367. 
4. Fumigation of Orchards and Turnip-Grounds, to des¬ 
troy Insects. —Long dung, wet straw, weeds, &c. on every side, 
in heaps, and likewise some in different parts of the inclosure, set¬ 
ting fire to some of the heaps on the east side, if an east wind blow, 
and some within the body of the orchard, but always on the side 
from whence the wind happens to blow, so that the smoke from the 
smothering of the heaps may blow through and fumigate for some 
weeks.—Vol. 4, see p. 203—210. In harrowing or brushing in 
Turnip Seed, add to the harrow or thorn bush, a hush of stinking- 
elder, (Sambacus) the dragging which over the field will leave such 
a disagreeable smell, as will probably be sufficient without other fu¬ 
migation. 
5. The Cranberry. —At Sir Joseph Banks’s, at Spring Grove, 
near Hounslow, a cranberry-bed was constructed on the side of the 
pond, (in 1805) twenty feet long, by five and a half broad, a few 
stakes being driven into the bottom, parallel to the side, and lined 
with old boards. The bottom of this was filled up with stones and 
rubbish, and on these was laid a bed of black mould, three inches 
above, or seven inches below the usual surface of the water. On this 
the plants were placed; and in the autumn of 1807, they produced 
an abundant crop of fine fruit; about five dozen bottles were gathered. 
The plants were of the American sort, and ripen well, without being 
subject to the attack of vermin, or to injury from excesses of heat or 
cold, wetness or drought. 
6. Method of Cultivating Geraniums. —Take up the old 
roots in autumn, and instead of throwing them away after taking 
cuttings, shake off the earth from the roots, and taking away all the 
succulent branches, lay the roots by the heels in sand, in a common 
frame, to preserve them from frost. Plant them out in April, and 
they will bloom during the summer. A hedge has been successfully 
managed in this way.
