What mak' ye o' the phrase, no confined to the Scots tongue, I believe, o' an eaves-drapper?
The whilk, no doobt, represents a body that hings aboot yer winnock, like a drap hangin' ower abune it frae the eaves--therefore called an eaves drapper.

But the sort of whilk we noo speak, are a waur sort a'thegither; for they come to the inside o' yer hoose, o' yer verra chaumer, an' hing oot their lang lugs to hear what ye carena to be hard save by a dooce frien' or twa ower a het tum'ler.' At the same moment the door opened, and a man entered, who was received with unusual welcome.
'Bless my sowl!' said the president, rising; 'it's Mr.Lammie!--Come awa', Mr.Lammie.Sit doon; sit doon.

He was characterized by a certain simple alacrity, a gentle, but outspeaking readiness, which made him a favourite.
'I dinna richtly mak' oot wha ye are,' he answered.

'Ye hae unco little licht here! Hoo are ye a', gentlemen?
I s' discover ye by degrees, and pay my respecks accordin'.' And he drew a chair to the table.
''Deed I wuss ye wad,' returned MacGregor, in a voice pretentiously hushed, but none the less audible.
