ON the 10th of July, a beautiful morning, but rather chilly, 

 for there had been a sharp frost, not an unusal occurrence in 

 these mountainous localities, we started at four o'clock. The 

 sun was already up, and shining on the head and shoulders of 

 Ben Ledi, "that raised its ridge in air;" but the genial effects 

 of solar heat were unfelt in the valley where we were, and the 

 benumbing effects of the chilling, damp, frosty atmosphere were 

 felt at our finger-ends. The great length of daylight, even at 

 Edinburgh, was one of the phenomena not unobserved. In the 

 beginning of July the light at nearly eleven o'clock in the evening 

 was quite equal or greater than the light at nine P.M. in London. 

 The sun, after setting, is several degrees nearer the horizon in 

 Scotland, than in the south of England. The sun's dip under the 

 horizon is as much less in the Scottish capital, as the latitude of 

 London is less than that of the former ; or, in other terms, the 

 difference of latitude will be the difference of the sun's horizontal 

 depression in the two places respectively. But there is another 

 minor cause of the excess of the twilight in Scotland above that 

 of London, viz. the greater purity of the atmosphere. The 

 causes of greater atmospheric purity are not so simple as the 

 above-stated cause of long twilight; but the facts are well 

 known. 



The road lies along the left bank of the eastern branch of the 

 Teith, by the little hamlet of Kilmahog, where the celebrated 

 Pass of Leny commences. This Pass is formed by a spur of Ben 

 Ledi on the West, and a similar spur of Benvoirlich on the east. 

 The river rather rushes than runs through this defile. It forms 

 a series of rapids, or a succession of abrupt falls, for the space of 

 about a mile : where it issues from the lake it is as placid as the 

 Loch itself. The road is a good one, as all the Highland roads
