distempers in wheat.

ashes, but reported the above as the preceding tillage. 
There can be no doubt but the failure was owins to the 
excessive tillage, in which the land had been fouled 
by the seeds of the above weed, whose growth was ac¬ 
celerated by the manure; I have known other instances 
of over-tilled land being rendered foul, so as to choke 
the crop by applying manure, which does more harm 
than good to any crop, unless the land can be kept 
clean from weeds. 
Notwithstanding this failure, the average crop of 
wheat in Worcestershire may be put high. I estimate 
the common fields and light sandy land to produce 
20 bushels per acre, the enclosed loams to average 
4 quarters at least, or 32 bushels of y gallons each, which 
is the usual Worcestershire measure, and will weis-h 
upon the average 70lbs. weight. In the Yale of Eve¬ 
sham in good enclosed land the blue cone wheat will 
often produce from 40 to 45 bushels per acre; the 
average of seed sown is two bushels and a half per acre; 
sometimes on strong land, and late in the season, three 
bushels per acre are sown. 
The distempers to which wheat in this county is 
principally subject are, mildew and smut; of the 
former there is no great complaint this season: I saw it 
only in a few instances, and mostly in the parishes of 
Littleton. No attempt has ever been made at prevention 
or cure, or can be I suppose, other than good husban¬ 
dry, keeping the land clean, and sowing in proper sea¬ 
son a good sort of grain; the cause is, I believe, in 
the atmosphere, too much humidity and want of sun¬ 
shine, the proximate causes, and improper tillage and 
an abundance of weeds the predisposing ones. With 
respect to minute fungi being the cause of this distem¬ 
per; this is doubtless beginning at the wrong end ; such,
