tivation of carrots, beets, cabbages &c. and when it 

 is intended to manure an old meadow. 



Q. What inconveniences result from the use of 

 green dung ? 



A. Green dung has the inconvenience of contain- 

 ing noxious seeds which later on shoot and infest 

 the cultivated lands ; it does not contain, moreover, 

 as many rich fertilizing agents, as the dungs which 

 have begun to ferment, 



Q. Does the use of green dung oh fields in which 



vegetables are to be grown, offer the same inconve- 

 nience ? 



' A. No, because the numerous weedings to which 

 these fields are submitted destroy the weeds ; but 

 even in this case, the dungs which have begone to 

 ferment have a much greater value. 



Q. Are weed seeds also found in roten dung ? 



A. There are no weed seeds in rotten dung, be- 

 cause these seeds are decomposed by the putrefac- 

 tion of the dung. 



Q. What is meant by cold and hot dungs ? 



A. Cold dungs are those which ferment and decay 

 slowly and with difficulty; hot dungs are those 

 which ferment and decay rapidly. 



Q. Give illustrations of these two kinds of dungs ? 



A. The cow and swine dungs are cold manures, 

 the horse and sheep dungs are hot manures.
