There was a popular song based on this first line of Longfellow's - the one quoted above, attrib to Glenn Miller in google, with the blacksmith shouting "chestnuts!", which was danced to with actions like putting hands on chests & heads to accompany 'chest - nuts'. A children's version we used to sing, late 30s, went

Under the spreading chestnut tree
Arthur Askey said to me
"If you want to get your gas-mask free
Join the blinking ARP!"

~M~

Notes: Arthur Askey a very popular radio comedian of the time. The name of the celeb mentioned at this point varied acc to taste of the singer. The Opies, in Lore & Language of Schoolchildren give, probably more convincingly, "Mr Chamberlain", Prime Minister just back from Munich promising "Peace in our time" but still going on with Civil Defence preparations like Air Raid Precautions [ARP]. They date it to 1938, but state it was still a girls' ball-bouncing chant in Aberdeen in 1952!

Most had to pay one shilling and sixpence [eighteen old pence] for their gas-mask, the ownership of which was nevertheless compulsory in the prewar years of war-crisis; but by joining a Civil Defence organisation like ARP and becoming an Air Raid Warden [like Mr Hodges in Dad's Army], one could get it issued free (my father was one from 1938: I still have his badges [real hallmarked silver!] & the metal strip attached to our front gate to show a warden lived there).
