Dee) on the culture of madder. May 23. 
ly first to the one side the row about the whole interval, and 
then on the other side, so as never to leave the plants bare 
of earth at both sides at the same time. It would require 
many words to describe this procefs, so as to be intelli- 
gible; but any ploughman might be taught to do it by prac- 
tice in a few minutes; nor have I ever seen a procefs in 
agriculture that is more perfect or more easy. The plants 
thus cultivated may be taken up at the end of this year if 
niecefsary, or they may be taken up during any part of the 
succeeding season, as fhall suit the conveniency of the par- 
ties. : 
- If the season fhould prove wet in the autumn, the 
planting the roots may be deferred till the spring ; but im 
general the autumnal planting is the most advisable, as it does 
not retard the growth in the spring. This kind of madder 
fhows itself earlier in the spring than the common kind. | 
The roots of madder descend to a great depth, where 
the soil is favourable, and being naturally tender, they must 
be taken up with great care. The Smyrna roots, as has 
been said, are firmer and more compact than the ordinary 
sort, and have fewer crop fibres, so that they may be 
more easily taken up, and have lefs refuse than the other 
sort. 
Where it is intended that the plants fhould be used freth, © 
they may be taken up at any season of the year they are 
wanted, and they can be preserved frefh fora very long 
«ime, merely by laying them pretty close together in any 
convenient place, and putting earth about them, so as to 
prevent them from touching each other too near and heat- 
ing. In this way they can be preserved many months, 
awith no danger and little trouble. 
I thall conclude this article with the account of the re- 
sult of Mr d’Ambourney’s experiments with the green 
root, which /hall Le given in our nevt.
