Not content with this fingle trial, I determined 

 to repeat my experiment (till farther: therefore, 

 in the latter end of autumn 1776, after having 

 taken the haulm and feed off, I manured fix acres 

 of wheat-ftubble, which I intended for turnips the 

 enfuing feafon. This done, I immediately plowed 

 it, leaving it to incorporate freely with the earth 

 till the following fummer, which had the defired 

 effect; for the turnips which grew upon it were 

 as large as thofe on the land which had been 

 manured. 



The two fucceeding years, 1778 and 1779, I 

 repeated this experiment, which anfwered beyond 

 my utmoft expectation. Hence I infer, that the 

 fly is cither ingendered in the new muck [dung] 

 or inticed by it. But when this manure is laid 

 on in the autumn preceding, it lofes all its noxious 

 qualities, and, from what I have obferved, retains 

 all its nutritive ones; though, philofophically 

 fpeaking, they are liable to be in fome degree ex- 

 haled by the heat of the fun. 



Another material advantage accruing from au- 

 tumn manuring for turnips is, that all the feeds 

 contained in the manure, and which of courfe are 

 carried on the land with it, vegetate almoft im- 

 mediately, and are moftly killed by the leverity of
