THE LOCH LOMOND AND OTHER VALLEYS. 221 



the fiord of Loch Fyne consists of a series of fea- 

 tures which are more or less systematic; for the 

 deep portions extend along regular lines, and where 

 these lines cross or join into one another, there 

 are extra deep soundings, and each shift in these 

 lines corresponds with lines of features in the 

 adjoining country. G-lenshira is connected with a 

 break in the strata, and Glenary appears as if it 

 followed a similar line. However, the drift greatly 

 obscures the evidence in the latter case ; but the 

 sudden deep opposite Inverary lies at the junction of 

 these two lines with those of the breaks that exist 

 higher up and lower down in the main channel of the 

 fiord; while a little farther S.W. one of the deepest 

 spots in the upper portion of the loch is where the 

 break occupied by the Douglas Water joins into and 

 slightly deflects the main break. The island and 

 shoals at Minard Narrows seem to be brought up by 

 a fault ; so also does the Otters Spit, and the various 

 islands and shoals in the bay ; but as the country in 

 the vicinity of Loch Fyne was not all examined, nothing 

 further can be said about them. 



The lower portion of this fiord has a nearly 

 gradual slope from the Frith of Clyde to the Otters 

 Spit Narrows, but N.N.E. of these to Minard Narrows 

 there are deeps, which, however, are not as considerable 

 as those previously mentioned in the reach between 

 Minard and Loch Shira. These different soundings
