CLIMATE

the prevalence of south-westerly winds, accompanied by fre-quent showers, and often long tracts of rainy weather,

6. That the influence of the German Ocean, upon the eastcoast of Scotland , is also very considerable. Being five de-grees warmer in summer, than the Atlantic, a copious eva-poration takes place, throughout its extent, which producesthe eastern hoars (as they are called) or thick mists, whichare seen, at a certain period of the day, to arise from thesea, and advancing upon the land, occasion colds and otherdisorders.

3. Peculiar Soil and Natural Productions,

Countries, in a state of nature, are found to be colder thancountries in the same latitude, which have been long undercultivation; which accounts, in a great measure, for the dif-ference of climate under the same parallels, in Europe andAmerica . .

The soil of Scotland , in several districts, especially on theeastern coast, is dry, and a great proportion of it cultivated.Hence, the climate is warmer, than in some other countries,in the same latitude.

It seems unquestionable, that the prevalence of carse or claysoil, or peat, more especially when undrained, and probablytoo, of woods, at least in flat countries, has some effect uponthe climate of the adjacent districts.

An instance of the influence of a carse soil, is given in theStirlingshire Report *. In the carses of that district, inter-mittent fevers had formerly prevailed; but by an improvedmode of ploughing, and more effectual draining, joined toother circumstances, as more substantial houses, better food,clothing, &c. these fevers have disappeared. From the samecauses, agues have likewise disappeared in other parts of Scot-land .
