Which sound device is emphasized in both of these poetic passages

by the shores of gitche gumee,
by the shining big-sea-water,
stood the wigwam of nokomis,
daughter of the moon, nokomis.
dark behind it rose the forest,
rose the black and gloomy pine-trees,
rose the firs with cones upon them;
bright before it beat the water,
beat the clear and sunny water,
beat the shining big-sea-water.
(henry wadsworth longfellow, "the song of hiawatha")

we rest.—a dream has power to poison sleep;
we rise.—one wandering thought pollutes the day;
we feel, conceive or reason, laugh or weep;
embrace fond woe, or cast our cares away:
(percy shelley, "mutability")
