78 NOTES ON THE BIRDS OP lONA. 



green, It is yet sufficiently obvious that the flat space along the river below 

 the High Green and Flesher's Htiugh, may have been a beach; and the 

 flat expanse of King's Park and the High Green sloping up to Monteith 

 How, another. The second of these levels gives us the line of London-Street 

 and Trongate, and may be traced in this way a considerable distance. Mr. 

 Kobert Chambers describes the terraces of Glasgow in these words: — 



^'If we make a cross movement from the river bank at the Broomielaw, 

 the following ancient beaches will be found: — First, the street of Broomielaw, 

 a piece of ancient haugh ten feet above high-water mark* second, another 

 flat at Anduston, at about thirty feet; third, a terrace sloping up to the 

 skirts of Garnet Hill, somewhat irregular, but exhibiting some entire pieces, 

 (for example the site of St. Matthew's Free Church,) and attaining an extreme 

 height of somewhat more than eighty feet. A similar cross movement in the 

 eastern suburbs, starting at the green and passing up to the lodge at the 

 house of refuge, gives a precise repetition of these gradations. The Mill- 

 Street Factory is there seated upon the sixty-four — seventy feet level. In the 

 central part of the city we pass at once from the twenty- six alluvium, (for 

 example at George Square,) up a steep slope to an irregular height, not less 

 than one hundred feet, remarkable for a capping of dikivium, containing a 

 number of far transported boulders. But in the line of the High Street, the 

 University Buildings clearly sit upon the same terrace which we find at 

 Dowanhill and the Mill-Street Factory. On the right bank of the Moleud- 

 mar Burn, opposite Craig Park, there is a fine piece of terrace about one 

 hundred and fifty yards in length, and perhaps fifty above the tiny stream. 

 This is approximately about one hundred and forty-four feet above the level 



of the sea."

NOTES ON THE BIRDS OF lONA. 



BY HENRY D. GRAHAM, ESQ. 



[I HAVE much pleasure in forwarding you the accompanying notes, addressed 

 to me by my esteemed correspondent Mr. Graham. Few observers are better 

 situated than that gentleman for noticing the occurrence and habits of some 

 of the rarer sea-fowl; and as he has, for a considerable time, paid close 

 attention to ornithological pursuits, under the most favourable circumstances, 

 it is likely his letters may prove interesting to many of your readers. I have 

 only to add that Mr. Graham is quite an enthusiast, and the observing the 

 habits of sea-birds especially affords him untiring delight. "I love," he says, 

 '^to pursue the aquatic tribes upon their own blue element, and to 'hunt a 

 field for health unbought.' I have spent days and nights in 'solitary places,' 

 watching them with my dog and gun, and I look upon the wild screaming 

 races that people the rocks, the caverns, and the sea-waves, as the companions 

 of some of my happiest hours."
