the latter.** The foil of the experiment 

 ground is a rich black mold, worth 25 /. 

 per acre. 



Madder. 

 In May 1768, one row of madder plants, 

 four feet from the rows of other things, 

 and eight inches from plant to plant, was 

 fet in the experiment ground : I never 

 viewed any plants mere luxuriant. They 

 are regularly horfe-hoed and hand-weeded; 

 and will, I have no doubt, become in two 

 years a fine crop, and a vaft one in three. 

 Mr. Scroope propofes extending the plaDta- 

 tion to more rovv^s by flips. No foil can 

 pofFibly be better fuited to it. 



Hollow Drains. 



In the draining w^et foils, this moft fpirited 

 cultivator has found no method fo efficacious 

 as the hollow drain. His method of making 

 them is to cut a trench 27 inches deep, 18 

 inches wide at top, and four inches wide at 

 bottom ; they are filled up by crouding 

 large flones in, fo as to lodge (wedged) 

 within fix or eight inches of the bottom ; 

 Over thefe they are filled up with fmaller 

 ftones within a foot of the furface ; over 

 thefe, is a layer of bean flraw, and then the 

 remainder of the trench is filled up with the 

 molds. The digging cofts 3^. a rood. 



Their cfFed is prodigious ; the wetteft 

 foils are at once laid dry and found, and
