Sir, – While watching, for the first time, a perplexed swallow hunting in vain for flies over my lightly frosted lawn some mornings ago, I fell to wondering what if this is not the last frost of this winter but the first frost of the next? And if so, ( pace the swallow) is this a first? – Yours, etc,
LIAM J McMULLIN,
Donamon, Co Roscommon.
