The poem is written in really old Swedish. A modern way of writing it would be something like this: När skönheten (/konsten) kom till byn då var klokheten där, då hade de bara elaka saker att säga. Då sköt de efter henne med tusen gevär, (De gjorde allt för att bli av med det/henne) eftersom de ju var så förutseende allihop. When beauty came to the village the wisdom was there, then they only had bad things to say about it. They shot after it/her with a thousand guns (They did all they could to remove it/her from their sight), as they were oh so farsighted Or something like that...

Wenn die Schönheit zum Dorf gekommen ist, dann die Klugheit da war, dann sie allein Dorn und Galle hatten. Dann sie auf sie mit tausenden Gewehren schießten, weil sie alle so verklugt sind. Ferlin makes up a non-existing verb for himself, writen in german maybe Ferlin would've wrote the poem something like this. Just kidding:-p

I do not know the translation of the word, but I found translation of the whole poem http://johnirons.blogspot.se/2012/02/another-famous-poem-by-swedish-poet.html May be that will help you
