Thusa temperature iscaused whichfavors active ex-ertion through-out the year, thesummer days be-ing rarely hot,the winter rarelyexcessively prevailing westerlies, carrying an abundance of moisture (p. 161), sodistribute it over the islands that no section suffers fromdrought. Yet the western portions receive more rainthan the eastern because the ocean winds visit them first(Fig. 126). The highlands also influence the rainfall. A highland rim.

(Fig. 126). Highlands are also found in Wales, west-ern England, and most of Scotland (Fig. 122). Examine Figure126 to seewhere the rain-fall is heaviestin Great Brit-ain. Where isthe rainfalllightest?Why? As alreadystated (), themountains ofGreat Brit-ain, like thoseof New Eng-land, are soold that theyare worn verylow. Whilethis upland israrely morethan one ortwo thousandfeet abovesea-level, there are occasional peaks of hard rock that rise to agreater height (Fig. 127). For example, the granite peakof Ben Nevis in Scotland, the highest point in the BritishIsles, is forty-three hundred feet in elevation. The Scot-
