Come see the north-wind’s masonry.
Out of an unseen quarry evermore
Furnish’d with tile, the fierce artificer
Curves his white bastions with projected roof
Round every windward stake, or tree, or door.
Speeding, the myriad-handed, his wild work
So fanciful, so savage, nought cares he
For number or proportion. Mockingly
On coop or kennel he hangs Parian wreaths;
A swan-like form invests the hidden thorn;
