sea seemed to have a beneficial influence in preventing orlessening the disease. Much of the wheat crop, in varioussoils and situations, was comparatively exempted, or so littleinjured as to give an abundant produce, and of good quality:But no circumstances occurred that could throw any light outhe causes of these differences, at least in a practical view ofthe subject, so as to point out any means of preventing oreven lessening the evil on any future opportunity *.
“ As far as could be learnt in Berwickshire, where the re-porter then resided, all kinds of wheat usually cultivated tliefe,were equally affected by the disease, or nearly so; other cir-cumstances being similar, the variety named creeping wheatexcepted. In East Lothian , the thin-chaffed wheats sufferedmuch loss injury than the thick-chaffed varieties. Both au-tnmn-sown and spring sown wheats were affected, but the au-tumn-sown obviously and materially more so than the spring-sown crops. This difference was perhaps owing to the spring-sown crops having lowered later than the autumn-sown, soas not to have had so.much of its pollen washed away. Beard-ed wheat is not cultivated as a kind in Berwickshire; yet headsof that variety are often found in most fields, more or less nu-merous, as an accidental mixture. A field of wheat infectedby the mildew,, in which there was a considerable intermix-ture of bearded wheat, was carefully inspected in autumn.LS08, but no difference could be perceived in the degree ofdisease between the bearded, and the smooth eared kinds.This observation was particularly attended to, because in thebefore-mentioned queries, it was mlleged that bearded wheatswere not nearly so liable to the disease. Perhaps the beardedkinds there alluded to, belonged to the summer species, ortriticum ccstivum.
* Hedges and trees, by preventing a free circulation of air, would detain viols-'ture longer on the grain, than in open situations. Near tire sea, there is gene-rally a circulation of air occasioned by the- tides, periiaps even in the calmestweather.
