-By the shores of Gitche Gumee,
B<u>y</u> the sh<u>i</u>ning Big-Sea-Water,
Stood the wigwam <u>o</u>f N<u>o</u>k<u>o</u>mis,

Dark behind it r<u>o</u>se the f<u>o</u>rest,
Rose the black and gloomy pine-trees,
R<u>o</u>se th<u>e</u> firs with c<u>o</u>nes up<u>o</u>n th<u>e</u>m;
Bright b<u>e</u>fore it b<u>e</u>at the water,
B<u>ea</u>t the cl<u>ea</u>r <u>a</u>nd sunny w<u>a</u>ter,

Embrace fond w<u>oe</u>, or cast our cares <u>a</u>way:
