Ay , an' the gowk 'ill come next year , The mavis fin' anither hame ; The burnie dance alang as clear , The bees gang singing * ower the kaim . The nuts an' slaes hang ripely doun ,

An' lads an' lassies pu' them fain ; An' hearken tae the laverock ' s tune , When next year shall come roun' again . It ' s this my mither aye has said , She doesna see sae clear * as I , That I hae reeled aff a' my thread , An' laid my rock an' reels a' by . '
