212 I'HE KITCHEN-GARDEN. [March. 
considerably strong, for if exposed fu ly to this, during their infant 
Slate, few uftlieni would escape destruction thereby; were you to 
place a piece of board on end, about fifteen inches broad, and two 
feet and a half high, at the south side of each hill, leaning a little 
over the plants, this would answer the end effectually, without de- 
priving them of the benefit of the circulating air. The first season 
is their critical period, having survived that, they have nothing to 
fear afterwards. Onions, lettuces or any other low growing crops, 
may be either sown or planted in the intervals for the first year, so 
that they are kept at a proper distance from the young plants. The 
supernumerary plants, one being sufficient to be left in each of these 
places for ultimate perfection, may be transplanted the spring fol- 
lowing into new plantations, similarly prepared and at the same dis- 
tance. 
The November following, all the leaves being then decayed, cover 
the crowns of the plants two inches deep with earth from the inter- 
vals, and if there is danger of any wet lodging, throw up trenches, 
rounding the beds as is commonly done to asparagus, and for the 
first winter, lay some dry litter over the plants. In the March 
following, strip the covering till you just perceive the tops of the 
plants, give all the ground a slight digging and dress it neatly after 
you, observing to keep the beds well hoed, and always free from 
weeds 
Thus proceed every autumn and spring, till the roots have four 
years growth, when some of them may be taken up for use; but it 
is generally admitted that their medicinal virtues increase, until they 
are eight or ten years old. 
You must be very circumspect in the choice of ground; particu- 
larly, that it is not subject to lodge wet, for this plant, by no means 
agrees with too much moisuue; preferring a rich dry sandy loam, 
to any other kind of soil, 
RhuDarb may also be propagated by offsets from the old roots, or 
by sowing the seed in seed-beds, and transplanting them when a 
year old, into such beds and at the same distances as befoie directed 
for sowing the seed; but they always produce larger and better 
roots, when sown where they are to reuiain. 
The proper time to take up the roots for use, is in autumn, after 
the leaves and stalks are totally decayed; when taken up, wash them 
clean, trim off the small fibres, and lay them in an airy place to dry, 
for four days, then rasp off the outward skin which greatly obstructs 
the quickness of drying, from the pores not being laid open for the 
herbaceous moisture to exhale; the mere stripping off the bark, will 
not be sufficient, the rasping it off, and the lacerating of the out- 
ward part of the root adjoining it, will be necessary; for, the lateral 
pores must be opened, lo permit the confined watery fluid to exude 
freely. Then cut them in slices, which string on pack-thread so as 
not to touch, and hang them up in a stove-room, to be kept con- 
stantly warm till they are effectually dry. Should the season even 
prove hot enough for drying them in the sun, the former method 
would be preferable; for by exposing them so much to the sun and 
light, they would be greatly impaired in the colour, and perhaps
